Sulfate-free hair dye is a type of hair dye that does not contain sulfates, which are harsh detergents that can strip the hair of its natural oils, causing it to become dry, brittle, and frizzy. Sulfate-free hair dyes are gentler on the hair and scalp, and they can help to preserve the hair's natural moisture balance.
Sulfate-free hair dyes have become increasingly popular in recent years as people have become more aware of the potential damage that sulfates can cause to the hair. These dyes are available in a wide range of colors and formulas, and they can be used to achieve a variety of different looks. Sulfate-free hair dyes are also less likely to cause scalp irritation and allergic reactions.
