Who neither listen or read, everyone is afraid of coloring agents ammonia. It is believed that it will be gentle without him. This is not entirely true, the damage causes a completely different component of hair.
Ammonia only accelerates the process of injury to the hair itself, but not the primary cause of injury. Remember this.
Hazardous ingredients for hair - hydrogen peroxide. That is how much of it is contained in a percentage, the degree of damage to the hair depends. And the damage, I should say - permanently, it will be impossible to restore the hair from the word at all, if you use coloring agent with the content of hydrogen peroxide is more than 3%.
I can tell you as someone who is not the first year delivers supplies for masters of beauty salons and barbershops: blondirovanie often used in 9%, and then all of 12%. But extreme expose somehow ammonia.
Do not forget such a simple thing. Our hair is made of protein. Any staining - a thermal and chemical burns in one bottle. When you cook the eggs in a pan, then its elastic protein folds and becomes brittle. Is it possible to return the egg white is somehow old liquid form? Not. That's the same thing with the hair.
Staining with a 9% content of hydrogen peroxide - is a chemical burn. Corrosive elements evaporated from water cells burnt hair. Everything, no caring oil will not help them to harsh chemicals do not become less aggressive.
So pay attention to the content of H2O2 (hydrogen peroxide), and it does not matter - is present in the hair dye, ammonia or not.
