Insane
Hair felt insane instantly after, also curls now last 2/3 days which is unheard of for my hair, unsure how but must be related

It worked for me
I have very fine hair and I really noticed a difference after using this. A little goes a long way with the product so one bottle lasts several months and whilst it is expensive I think it's worth the money.
