Keratin Express Plus 4 FL oz Smoothing Treatment Professional Hair Treatment up to 12 weeks Do not use it on Pregnant Women, Children and Nursing.This product contains Formaldehyde

Instant manageability, shine, and damage repair! My hair looks and feels so much better than the $150 for a keratin express treatment from my stylist.

I’ve used this product for many years, i have frizzy hair and this product makes it soft and smooth. It lasts around three to four months. I will always use it

used this for a long time. best product.

I like that the serum can be sprayed & doesn’t go on heavy, which makes it easier to dry before straightening. I don’t think it lasts 12 weeks but this keratin is easy to use & isn’t a time suck.

This stuff is the best! Lasts about 6-8 weeks and no frizz, and I have frizzy hair!
