Went for a keratin treatment over a month ago and the smell of the chemical she uses is nasty. At first i thought it would be a temporary thing, but it has been over a month, and every time i wash my hair, no matter what kind of shampoo, it brings out that horrible smell of the treatment. My husband unfortunately has to put up with the smell and i cant wait til it wears off. My hair also didnt even stay straight as she said it would be. The only plus (and reason for 2 not 1 star) is my hair does feel softer. Do not go here for a keratin treatment unless you want to leave smelling like a wet dog.
