You only need a tiny amount, this lathers massively.
I have oily roots and use this every 2 weeks or so. Makes hair squeaky clean. I also use it on my 5 year old every 2 weeks to get rid of the buildup of anti tangle spays and conditioners I use on her. I honestly don’t know if it’s worth the price though. I can see it lasting ages. Couldn’t use it every wash though, it’s very drying and I feel might strip hair too much.
I found that this was a super hydrating, and fairly good toner. it didn't leave pigmentation in my hair, and I found that my fine hair was easy to comb after a shower (which is consistently an issue for me). I would certainly recommend this to others who are seeking a mild tone and a nourishing product.
Loving this as a treatment for my hair, it is great for fine hair and would definitely recommend as an addition to the normal hair care routine! Really adds volume, only downside is it’s a little pricey, but you don’t need much to go a long way.
