Too early to see
Seen this all over the internet and finally bit the bullet, it’s too early to comment on how it’s repaired my hair but I can say you only need one pump and my hair does feel really nice after using it

I love it
I love the damage repair from using this after only one week. One of the best benefits is I no longer need to straighten my hair which keeps it healthier and saves me time.

Amazing
I have 3b/c curly and very thick hair which is very prone to damage and and frizz. I was skeptical try this as the price is so steep but bought it in the sale and it transformed my hair. A little bit does go a long way but with the density of my hair I only get around 3-4 uses per bottle (which is a lot more than I could get out of another product of this size) and so my only complaint is the size.
