had this done at their salon. I never had a problem with keratin, nor did I request "environmentally safe" nor anything lke that. In fact, all I asked was for Keratin treatment in my hair.
The front of my hair is undyed and white (from my greying hair) I want it that way, and go through the trouble of not touching that part when I dye my hair at home, and when I go to the salon.
Chi changed the color of my hair. The dyed hair went from dark brown to reddish light brown. Any my undyed white is now caramel blond. I am very unhappy. I can always redye the back but the front I have to wait for it to regrow. That could take upwards of a year.
I've been reading the reviews and find that the color change is pretty common. If I had knonw there was even a possiblity of that, I would not have done it. And to add insult to injury, my hair is still frizzy. A tiny bit less, but definitely not worth the money.
i am a stylist. it's hard to determine what a chemical process will do to your hair, each person's hair is different. it may produce the same result in 99 people, but that 1 last person may experience something completely different. results can be affected by many things, such as medicines, illnesses, allergies, or previous hair treatments.
i'm sorry you had a bad experience, but don't let that sour you on the salon, stylist, or the product. for frizz, try to apply a tiny amount of leave-in conditioner or smoothing treatment. paul mitchell and it's a 10 have good products for that. also, try using a platinum shampoo, such as shimmering lights, to try to pull the caramel color out of your front. if you choose to recolor the back, you can use the shampoo all over and it will brighten up your color. i use another name brand of the same kind of shampoo and it keeps my blond highlights white instead of brassy or caramel.
