A chemical cut is a term used to describe severe hair damage caused by harsh chemicals from straightening treatments, coloring, excessive straightening, strands, or lights made with hair weakened by chemicals. It occurs when the bonds in the hair are broken due to over-processing from too much bleach, hair dye, or chemical straightening. The hair becomes so damaged that it looks messy, the ends look split, and the overall appearance is dull. In some cases, the bleach can actually eat away at the hair, causing it to melt and fall off in pieces. To avoid getting a chemical cut, it is best to limit the use of harsh chemicals on your hair and to take good care of your hair by using nourishing products and avoiding excessive heat styling. If you do end up with a chemical cut, there are ways to repair and revive your hair, such as using deep conditioning treatments and avoiding further chemical treatments until your hair has had a chance to recover.
