### ⭐⭐ No good for African hair.

### ⭐⭐⭐⭐⭐ I like it
*by R***. on 11 June 2026*

### ⭐⭐⭐⭐⭐ Amazing at home keratin treatment
*by K***O on 15 July 2026*

I have only ever used keratin complex treatment(NKST). It is to be used only by professionals but you can easily obtain it off of Ebay and Poshmark. It is supposed to be salon strength. The big drawback is you cannot wash your hair for three days after treatment. That is almost impossible for me. I tried this and process is exactly the same. Wash with clarifying shampoo, apply product, blow dry after thirty minutes and then flat iron. This was much more moisturizing and way less toxic smelling. NKST makes my eyes sting and my scalp will itch. This did none of those things. As soon as I finished flat ironing it, my hair felt completely different as opposed to the NKST post treatment. Much softer and it actually looked healthier. The NKST makes my hair feel like straw. Washed it the next am. Less than 24 hours. My hair is frizz free and easier to blow dry. I will be throwing away my remaining NKST product. This so far is amazing!!
