The Health Site explains that hair rebonding is a chemical process that breaks down existing bonds in hair and restructures it by creating new bonds. According to Fashion Central, hair loss is one of the most common side effects of the process. The chemicals weaken the hair and cause breakage.
The heat that is applied after the chemical treatment also causes damage, reports Fashion Central. It can burn the scalp if not applied properly. Rebonded hair also needs constant care in order to restore and maintain its health, and this can be expensive and time-consuming. To minimize the risk of negative effects, only a professional stylist should perform rebonding.
