This product is expensive but it was a last resort and I'm SO glad I decided to splurge on it. It leaves my hair feeling like I just walked out of the salon. I've only ever seen the results with air-drying so I imagine blow-dry results would be even better.
I'm not 100% sure how long you're meant to leave this on your hair but I put a 50c coin amount mid-ends (shoulder length hair) and leave it for 10-15 minutes then just rinse out. I found this gives much better results than just using it as a quick conditioner.
I strongly recommend this product if your hair is giving up trying to look decent and no other product is working for you.
