10 Ways Chemical Treatments Damage Your Hair


5. Brush damage

No matter how sleek your hair is, using a brush or comb will always cause friction, harming hairs by inflicting physical damage and by allowing chemicals to penetrate the hairs’ surfaces.  Breaks in the surface allow moisture to evaporate from within the hair, causing dryness, brittleness and eventual structural damage.  Since these are also symptoms of chemical damage, brush damage inflicts an inevitable toll on hair that may already be suffering from excessive treatment.  One way to minimize this is by avoiding brushing when hair is wet, since it is weaker and easier to break then.
