What is a common side effect of using hair bleach?

Using hair bleach often results in hair dryness and brittleness due to the harsh chemicals involved in the bleaching process. Bleach works by penetrating the hair shaft to strip away the natural pigments, which disrupts the hair's natural moisture balance. This disruption can lead to the depletion of essential oils and proteins that keep hair healthy, resulting in a texture that feels rough, dry, and more prone to breakage.

In contrast, options like hair growth, color retention, and increased shine are typically not associated with the side effects of bleaching. Hair growth is influenced by various factors including genetics and overall health, rather than directly linked to the bleaching process. Color retention is not a typical outcome of bleaching, as the concept involves removing color rather than maintaining it. Increased shine is often a result of healthy hair; bleaching generally has the opposite effect, leading to dullness due to the damage caused. Thus, the impact of bleach on hair health primarily manifests as dryness and brittleness, making it crucial for those undergoing bleaching to implement effective restoration and conditioning routines afterward.
