Is this for you?

The KEVIN.MURPHY Young.Again Immortelle Infused Treatment Oil is a weightless leave-in treatment oil infused with immortelle, to counteract the oxidisation and ageing processes.

Straightening irons, blow dryers and colour start the oxidisation process which damage the hair's cell structure and act like rust to decay the hair.

  1. Luxury


    This oil is the most beautiful I've ever used.
    Smells divine.
    A light weight oil that nourishes the hair without weighing down too much
    Love it
  2. Great pre blowdry serum


    I love this as a pre blow dry serum for my blonde locks. My hair has been in very very good condition since using this oil. I highly recommend for anyone with lack lustre/split or dry hair. comb hair, apply oil (one pump is enough), and then blowdry - style as per usual.
  3. Received a trial size


    I think it's lovely but I prefer cream leave in treatments too oil ones. If you prefer oil I would give this a try





  5. Brilliant!!!


    This product is one of my favourites by far! I got a sample and then purchased the full size. It works wonders, my hair is thick, dry and frizzy but when I use this it is so soft and shiny and not greasy at all! It works better when blowdrying my hair but is also amazing without heat. Love it
  6. My favourite hair product


    I love this product! Great for bleach damaged hair. I use it just after washing my hair. I also use it in my dry hair on the second day after washing just to add some moisture and shine back into the ends. Not as greasy or heavy as other products I have tried in the past.
  7. Lovely hair oil


    Really great hair oil. It nourishes my hair and leaves it feeling soft and healthy. I love the shine and the packaging is great. Really good price as well considering how much you get. This will easily last me about a year. Would recommend
  8. Really good for making hair look healthy


    I like that this oil doesn't make my hair feel heavy, it keeps it feeling clean and fresh. I try not to use too much, as it can make my hair feel a bit greasy otherwise.
  9. Best hair oil


    I have fine, wavy/curly coloured blonde hair. This product is one of the only oils that makes my hair silky smooth and healthy looking without making it look oily. I only need to use the oil after washing and if I wash 2-3 times a week, the oil gets me through at least 6-8 months! I'm onto my 4th bottle, have been using it for a few years now.
  10. Exceptional for my fine Asian hair


    I received a sample of this and wasn't expecting much. I usually avoid leave-in hair oils as they weigh my fine, straight Asian hair down. However, when travelling I couldn't bring my usual leave in conditioner spray so opted for this instead - it's EXCEPTIONAL. I air dried my hair the entire week and it was soft, smooth and glossy. It also stayed that way after putting a wave through with my ghd ...

  11. Best oil


    I am really loving this oil and it has done wonders for my hair. I also really love the packaging! Looks lovely on my bathroom vanity
  12. Better oil than most


    I got this oil in a pack with some other products and I switched over to using it from the oil I was using at the time (I'd been using the other product for a few years). Straight away you could tell it was a better quality product despite being at the same price point, the oil on my fingertips felt lighter and less greasy and I found I could get away with using much less product.

    I ...

  13. BETTER than Olaplex No 7 - big call I know


    This is actually amazing - rub it into damp almost dry ends only, and then blow dry and your hair is salon soft and looks amazing - for a really deep overnight treatment I rub it into my roots and ends and brush through and leave overnight before washing out. It lasts for ages, and is so cost efficient given the generous size and long shelf life. I use this every day. I rate it over Olaplex No 7.
  14. Worth its weight in gold!


    I love all of the Kevin Murphy products, even though they can seem a little on the pricey side they are definitely worth it. They feel and smell amazing in your hair and this particular item is a new staple.
  15. Love it

    Silky smooth

    Received free gift from adore. Really superb oil. Repair damage hair. Instantly felt silky smooth.
  16. Please bring back the DUO!


    Received as a sample and purchased the DUO with the leave in repair. That combination is incredible however this oil alone is something I would re-purchase. It has the perfect consistency to ensure that you hair is feeling healthy and not too oily. Also the best finishing product for slickness and a great shine.
  17. Amazing


    This is the most incredible hair product and lasts for ages making it worth every penny. I lather in into damp ends and then blow dry and my hair is soft, voluminous and silky.
  18. Lovely!


    Light but nourishing on my bleached hair. Smells great and makes my hair soft and shiny. Doesn’t weigh down. Great for everyday use.
  19. Light but luscious


    I have fine medium lightened hair, and my main goals and concerns are to keep body and prevent too much breaking from heat and colouring. I have used the Kevin Murphy Young Again serum for the last 6 years after my salon recommended it, it lasted a very long time, and I loved the way it didn’t weigh hair down, and smelled lovely. I really liked this product and it definitely can last a long time e...

  20. Bloody amazing


    This product is amazing. I have fairly thin, curly blonde hair and this is the only product that gets my knots out after I shower. It's also very lightweight so your hair doesnt look oily / doesnt get weighed down. Would 100% recommend.
  21. Worth every penny


    I have long straight hair that gets dry ends easily. Fairly fine hair but lots of it.

    I’ve tried them all. Oribe, kerastase etc and there’s nothing like this. It didn’t weigh my hair down at all. I get comments all the time on how great my hair looks!
  22. Nothing Special, disappointed


    I purchased this oil based on the amazing reviews it had. However for my hair it didn’t make the mark. My hair is still frizzy and dry after using this product religiously for over 3 weeks. Very disappointed given the price and fantastic reviews.
  23. No good for my hair


    I received a small bottle of this as a sample and unfortunately it didn't seem to nourish my curly coarse hair at all.
  24. Love this oil


    Although it is pricey I love this oil. You only need the smallest amount and if too much is put on it is heavy and slightly greasy but if used correctly it’s great!
  25. Great for thick hair!


    I've been using this product for over a year and recently gave it to my mum to try. We both have thick, coarse hair and we're enjoying the softness this leaves after blow-drying. Highly recommend!
  26. Ok


    Got this as a sample and wasn’t really impressed. There are cheaper hair oils out there that do an equally good or even better job.
  27. Makes my hair feel young again!


    Oil and freshly washed hair? Sounds like a recipe for disaster but you couldn’t be more wrong. I have oily roots and dry ends and was very concerned when using this product for the first time as I’ve found it hard to find treatment products that don’t weigh down my hair leaving it greasy. I love this product!! It leaves my hair silky smooth and frizz free. Would buy it 100 times over...
  28. Incredible product if used correctly!


    This was recommended to me by my hairdresser. I have fine, blonde, fragile, split end prone hair. You must use this product correctly though, if you don't use it properly, it will only end up making your hair oily. You wash your hair, then towel dry it. Wait until your hair is almost completely dry but still slightly damp, and then use one-two pumps worth of the serum, and massage it through your ...

    I received this product as a sample and did enjoy it!

    It doesn't have much of a smell and the texture was not what I was expecting - it was a gel type consistency rather than an oil.

    My hair did feel nice and was smooth but I didn't notice any amazing results for the price.
  30. lovely light oil that works well in fine hair


    After trying this product in a sample size I loved it and have ordered the full size bottle. I have fine mid length hair and I only use a small amount. It makes my hair feel soft & shiny when I blow dry it. Doesn’t feel greasy at all and dose not weigh my hair down either. It’s a very light pleasant fragrance but once put through the hair you can’t smell it at all. Love it and recommended it!
  31. Such a gorgeous oil


    My hair is pretty unruly. This is a fantastic oil that keeps my ends hydrated and so soft. Helps fight frizz as well. If you want beautifully soft hair, this is the product to use!
  32. love it!


    i received a sample of this with an order and it is great! i use it after washing and makes my hair smooth and soft for days! will buy a full size now as my hair just doesn't feel as nice without it
  33. Great product & it lasts!


    I usually alternate between using this and the Kérastase Serum Thérapiste Dual Treatment. The kerastase one is a tiny bit better but both are amazing and really help my dried out, highlighted, damaged hair. The only thing is this lasts 4x as long as the kerastase and therefore is a lot better value for money! Smells great, not too heavy and doesn't make my hair greasy! I will definitely keep buyi...

  34. I recommend this.


    I have enjoyed using this treatment oil. My hair looks so much healthier with the use of this.
  35. Tames the Beast without the grease


    This product is fantastic, often hair treatment oils can leave your hair feeling greasy and really heavy. This product is lightweight and smooths your hair leaving it feeling amazing. It smells heavily aswell, which is an added bonus. I use it nearly every day in my hair and have found it has made a big difference.
  36. Can't go without


    I just can't imagine my life without this now. I received a generous sample which lasted weeks with my last order. I am purchasing full size right now. I love this !!! I have processed blonde hair, fine and lacking in bounce. After using this product for a few weeks now I cannot go without it. This lightweight formula that distributes so easily has been a game changer. My hair is bouncy , nourishe...

  37. Totally amazing


    Tames curly frizzy hair without weighing it down. Scrunched it through the ends before putting on smooth again by Kevin Murphy (In damp hair) and it has worked so welll, I’m way over due for a hair cut so I have some split ends and frizziness but this almost feels like iv just had my hair cut. LOVE IT
  38. LOVE IT!


    OK, I used this years ago but recently got free samples of it and fell in love with it again, it tames my frizziness! I love the product would definitely recommend this as an after youve washed, blow dried and straightened your hair
  39. Hair feels soft


    My hair has bad chemical damage and this has managed to make my hair feel soft, I’m impressed by that.
  40. Smells amazing


    I received a deluxe sample with my goodie bag in my last adore order. This smells absolutely divine, and does treat hair. However, I have long, wavy thick hair which is already well hydrated and in good condition- I found that this weighed my hair down a bit, so i’ll now use it on my ends only.
  41. One of the best


    I have been using this product for years. It is so light and doesn’t add weight to your hair but it’s so silky and my hair has been in really good condition through continual use. Also great to add to dry hair when it’s a bit frizzy to tame it but not weigh it down. Better than any other hair oils/serums that I have used.
  42. Game changer!


    I received this oil as a sample size in a gift with purchase. It smells divine, made my hair super soft and shiny and helped control frizz.
  43. Great stuff!


    Was recommended this by my hairdresser and my hair is pretty fine and struggles to grow in some areas.
    This really helps my hair look shiny and thick, in addition to KM's other amazing products. As with most of the range, the product smells great and works. Can't fault it!
  44. Favourite


    My favourite product to use now having used Moroccan Oil & Biosilk in the past. It’s light, nourishing, non greasy, smells great & gives my hair a nice shine. My hair is healthier & stronger for using this product.
  45. Life changing...


    I have naturally very dry and difficult hair, and then I do everything I shouldn’t do to my hair (bleach it, use styling tools on it)... And since having a baby, I’ve found it’s needed a bit more love. Enter Kevin Murphy Treatment Oil. With one use, my hair is easier to manage, and feels (and looks) shiny and healthy.
    Could not recommend this product enough!!
  46. Smells Divine


    I have long thick bleached hair. I put this in after a shower and it helps de-tangle my hair. It feels light, smells divine and doesn't weight my hair down. The ends of my hair are looking a lot healthier and all my hair looks so shiny.
  47. Love it


    My hair is dry and brittle from bleaching from dark brown (nearly black) to blonde. This stuff is amazing and has done wonders for my dry ends. I have used it for a week and only on the ends of my hair. The frizzy is gone!
    The smell is amazing and it does not leave my thin hair feeling weighed down.
    Awesome and worth every cent. The product goes a long way!
  48. I Couldn't Be HAPPIER


    After every wash, I put about a 20cent piece worth of oil in the ends of my hair and on any areas with broken hair. I HAVE NOTICED A DIFFERENCE, my hair is happy, soft and growing well - a lot less breakage - a noticeable difference. I am 35yo, have been getting blonde foils for many years.
  49. Incredible


    Love love love. I have very curly hair which I blow dry. This is a fantastic oil that keeps my ends hydrated and so soft. Helps fight frizz as well. If you want beautifully soft hair, this is the product to use!
  50. Not moisturing enough for my very damaged and dry hair


    I was so hopeful about this product however it doesnt seem to do anything for my hair - it doesnt even feel like I have put product in. My hair is very dry and damaged tho. Trying to use it up so that I don't feel like I wasted money!
  51. This oil will make you belive in the power of Kevin!


    Can Kevin Murphy work miracles? Well I'm not sure about that, but the Young.Again treatment oil definitely works wonders for my hair. You only need the tiniest bit, just one drop worked through your hair to make a difference. My hair is a frizzy mess without it, and when I do heat style my hair I know it's protected by the Young.Again oil and won't dry out. Plus this product doesn't smell like som...

  52. Best product for soft hair


    I use heating products everyday so my ends are quite dry, this is the first product I've used that turned my straw hair into silk! Softens, de-tangles and makes it look shiny, I love this so much. Lasts ages, will definitely keep repurchasing.
  53. Lifesaver of a product for platinum blonde


    With platinum blonde hair, I’ve naturally experienced a ton of damage to my locks overtime including breakage and extreme dehydration.

    I’ve been using this product for 6-9 months in combination with Olaplex 3, 4 and 5 and have seen a drastic improvement in the strength of my hair. The KM formula is extremely nourishing but most suprisingly it’s still really lightweight.

  54. My Favourite hair product


    A little bit goes a long way with this one, so it's a wise investment. I bought my first bottle a few years ago and I only just finished it!it works very well and keeping my ends hydrated and minimising splitting.
  55. Hair restored


    Absolutely love this product. After months of over-using purple shampoo my hair was stripped and dry this has been the only product that has really restored it to a gorgeous feel and look. So soft and lustrious. Miracle
  56. Incredible Shine


    I have tape hair extensions which often get dry and dull looking and sometimes can even feel like straw. This is the only product which can rejuvenate them and make my hair feel like it is soft and silky. I apply this and then use my steampod to help the serum soak into the hair and I swear my dull hair actually shines after this. The product smells amazing and is so rich and nourishing you only n...

  57. This stuff LASTS


    I cant believe how much value/time I have got from one bottle. This definitely makes your hair feel softer, more manageable and healthier. Worth the price tag!
  58. Little Goes a Long Way


    This product is an oil, heat protector and a treatment. use the tiniest bit and it will go so far! Worth the price as this will last forever!
  59. Smoothes my curly hair


    I have fuzzy curly hair that is straightened more than its left natural. I use this to protect my hair from the straighter as recommended by my hairdresser 3 years ago and i haven't stopped using it since. 1 bottle lasts me around 1 year so its great value for money. I wont ever stop using this, my hair loves it
  60. Perfect!


    I have thick, damaged, coloured hair and this makes it feel softer than cashmere...I'm not kidding folks!


    I have extremely long curly dry hair. I have tried almost everything to hydrate and tame my frizz. This is an absolute miracle product. I no longer have to use any other styling products. This product is fantastic!
  62. Great and good for your hair


    Great product, free from nasties, WOULD RECOMMEND!
  63. Perfection


    Absolutely love this product, my hair started to go dry and nothing would work until this product. Makes it so soft its fantastic.
  64. Life Saver for Dry Hair


    Amazing Oil that does not make your hair greasy - just adds luster and shine.Can be used on wet or dry hair - both give amazing results.
  65. Amazing


    This stuff makes your hair feel like you’ve just been to the hairdressers and keeps it tame. My hair is a frizzy mess and this is my holy grail
  66. THE. BEST.


    I love this oil for my thick hair which is prone to getting pretty frizzy! I have tried so many different hair oils and this is my favourite for sure. I will definitely repurchase it whenever I run out.
  67. Awesome Product


    I have more different serums and oils that I care to admit - This one is the one. It never leaves your hair greasy or oily - you can use it dry or wet - just leave soft manageable hair with a lovely shine.
  68. Not great for thin hair


    My hair is suffering through a lot of breakage and a split ends. It is much thinner than normal and I found, when using this product that it became really oily even after I just had washed it. It smells amazing and I’m sure it would have aided in it healing if my hair hadn’t been so thin. Looking forward to trying this again once my hair is back to full thickness!
  69. Not just a cosmetic oil, it treats too!!!


    I didn’t believe that this product was a proper treatment, it just smells too good and I thought it was a finishing oil. After 3 or 4 applications I have noticed that it actually treats my hair. Took me a little while but am 100% happy with this product.
  70. Soft and Light-weight


    Although this brand is expensive, the oil worked really well in my hair, constantly making it smooth from the roots to the tip of the strand. I have really thick wavy hair, so it did make it easier to tame and use a curling iron or straightener.
  71. Good, but not amazing


    I do like this oil - it makes my hair smooth and doesn't leave it feeling greasy...however for the price, I think there are other hair oils that will do the same for far less.
  72. Fantastic for hair that has been through the wars


    I love using this product. It feels like a mini treatment on dry brittle hair. My hair responds to it & seems to retain the moisture.
  73. Leaves hair soft and smooth


    I have been using Kevin Murphy young again treatment oil for a few years and love it. My hair is lightened regularly and straightened daily.
    I have tried other products over the years, I always come back to this product, nothing compares.
    I use a tiny pump of this product in my damp hair, blow dry it and then straighten. My hair is manageable, soft and smooth.
  74. Great oil for processed hair

    Sarah melissa

    Bought this a few weeks ago and noticed the difference right away- great product. My hair was pretty damaged from bleach and very dry.
    Now it is ALOT healthier!
    Even on humid days this oil keeps my hair soft and smooth- worth the $$$
  75. Liquid Gold!!!


    This product is amazing!!! I was hesitant to purchase this because of the price but it is definitely worth it. I have lightened my hair quite a bit in the last few months so my hair was in desperate need of some moisture and a solution to my dry frizzy hair. I was previously using morrocan oil but I found that after I lightened my hair it just wasn't enough. This product has solved my frizz issue...

  76. A great treatment for dry, frizzy, lifeless hair


    I have been colouring my hair for years and as I get older my hair has become very dry, frizzy and lifeless and very difficult to control. I began using Kevin Murphy Young Again on the recommendation of my daughter and find that my hair looks much better and most importantly is easier to style. I am delighted to have found such a great product.
  77. Makes my hair soft and silky like nothing else can


    I will start by saying that my hair is coloured, curly, frizzy and I blow dry it every day. I have tried countless serums and oils on my hair but nothing has made it feel as soft as Young Again.
    My hairdresser used it on me a couple of months ago and I couldn't believe how it made my hair feel so I got online and bought some here because I'm a sucker for free chocolate :)
