DOES THE KERATIN TREATMENT CHANGE HAIR COLOR?Updated 2 years ago
When working with cold, gray and pearl shades of blonde it is very important to follow two rules. Firstly, you need to make sure you have no keratin left on after the treatment. Secondly, before flat ironing, the hair should be thoroughly dried at 100%. Do not leave wet strands or tips. If you do not follow these rules, then the cold, gray or pearl shades of blonde during ironing will change its color to yellow or yellow-orange.
Be especially careful if you have previously bleached, and then colored into a darker tone, hair. They can become much lighter. In other cases, no significant lightening.
