Even the best hair relaxers cause damaged hair. It is important to know how hair relaxing can be less damaging on the hair, and how growing out relaxed hair can be made faster. Hair vitamins can help relaxed hair by adding strength to hair, stop breakage and help grow faster!
Some people assume (falsely) that compared to lye hair relaxers, "no lye" hair relaxers are much safer and take the “damage” worry away from the hair. Both types of hair relaxers straighten the hair by breaking down di-sulfide (sulfur bonds) bonds in the hair.
Black hair relaxers not only break the di-sulfide bonds in the hair but they destroy them. This is what causes the hair to become straight. Both cause damage to the hair and both can cause irritation to the scalp if not used properly.
Lye relaxers contain sodium hydroxide as the active ingredient. With "no lye" hair relaxers, calcium hydroxide and guanidine carbonate are mixed to produce guanidine hydroxide. There are also “thio relaxers” they are made of thioglycolic Acid Salts. Namely diammonium dithiodiglycolate and or ammonium thioglycolate are the ingredients used in “thio relaxers”. Different brands will argue which has the lowest Ph, but as far as damaging the hair, all do a great job of destroying the s-bonds in the hair. The result is hair that is dry and damaged.
The best way to avoid damaged hair in relaxing the hair is to start out with strong healthy hair growth. When chemicals are applied to weakened hair in the beginning, the end result is far worse than if the hair was strong to begin with. By applying chemicals to weak (damaged) hair, you can almost except the result to be a disaster.
