I bleached (at a parlor) my hair about 6 months ago and have noticed a noticeable thinning overall in my hair since then. My question is does bleaching cause permanent hair loss?
When bleaching is done improperly, there are chemicals in the bleach that can burn your hair follicles resulting in a permanent loss of hair. We see this at times in professional salons when either the person doing is new, or the person doing it did not follow a strict protocol designed to prevent such happenings. When the damage happens, it kills hair follicles at the root. Sometime, Minoxidil (Rogaine) may grow new hairs, but this is generally not a reversible thing. If it particular bad in a single area, then maybe a hair transplant can address it,
