In brief: Trauma to hair bulb

The living part of the hair is the bulb, which is deep to the surface of the scalp.
Hair shaft is the non-living part. Hair dye, bleach, or perms do not cause permanent damage to the root of your hair, so the follicle can still regenerate another shaft. However, treatments that cause scarring such as hot combing or very tight braids or any process that cause scarring, resulting in permanent loss.

In brief: Dyes, perms

Bleaching, color treatments, permanents, hair straightening treatments can all have harm effects on hair health especially if they're done on a constant frequent basis.
It's also possible to be allergic to the chemicals used in these treatments which would cause severe rash and hair loss. If you notice breakage of hairs and patches of hair loss, that could be related to the hair treatments.
