Intense straightening shampoo for unruly, undisciplined or straightened hair.
Cleans and softens
Provides hair with the exact dose of nutrients and Pro-Keratin to discipline it.
Protects from frizz, purifying and softening hair.
Only the best
Enriched with Pro-Keratin and Kukui Oil and Evening Primrose Oil purifies the hair and scalp offering up to 4 days of anti-frizz effect, even with 80% humidity.
I was really worried because of the reviews I’d read, but it’s wonderful. I suppose it depends on your hair type, how frizzy it is, and the humidity. It worked perfectly for me because my hair is very unruly and it’s incredibly humid where I live. Keep all that in mind. It definitely adds shine and makes hair look nice; at least it worked perfectly for me.

I bought it two weeks ago, and it dries my hair and immediately makes it greasy, stiff, and dull. It’s an expensive product and I’m extremely disappointed.

I bought this shampoo for my daughter a few days ago because I trusted the brand, but it’s been the worst purchase of my life. It leaves her hair dirty, weighed down, and dull, like someone’s cracked an egg on her head. It’s awful. I don’t understand why they haven’t taken it off the market. It’s a rip-off. The brand should do something about it.

I bought the shampoo, mask, and serum two weeks ago, and it’s been terrible. My hair is greasy, looks dirty and lifeless, and my scalp is itchy.
