It helps in controlling hair loss and managing frizzy, weak, coarse hair.
I use organic's Hair color, and organic salon systems took in the company that started the keragreen treatment and reformulated it. Mind you, Organic salon systems is formulated in the UK and made there, they are ver strict on what goes into their color and products. I went to a class for color and the Keragreen treatment had just come out and they touched base on the treatment, I was very skeptical about the product but after seeing what it does and DOES NOT SMELL, at all... the L-cystine is actually a amino acid, which in some cases have found to stimulate more hair growth.
I currently do not have the product yet ( I am going to order in next week) I was sold when it first came out but the salon i worked for didn't want to buy it for me. I am very sensitive nosed, and we used a product called simply smooth keratin treatment and i was told it had not formaldehyde it in, they were wrong after doing testing there was .02 percent of formaldehyde. I could smell and clients could to. NOT GOOD!!! If i were to go with anything i would go with the keragreen over simply smooth anyway. If you want more information on it go to Organic Salon Systems Professional Organic Salon Products
they will give you a run down of the ingredients and what they are...
take it from a hairstylists point of view!!!
