Nano-Keratin Relaxer from Research In Beauty
Talking and Sharing about Nano Keratin
I am an hairstylist in bethesda MD. I use the Nano-Keratin Relaxer from Research In Beauty. I love the performance and the amount of formaldehyde is very low. It is 1.5% and compared to the Marcia Teixeira is much less disturbing in fact is not disturbing at all. I`ve used the marcia before I tried this one and I can tell you guys that is much better.
This is my opinion.
