What types of injuries to the scalp can lead to irreversible damage to the hair follicles? Do minor damage to the epidermis (superficial abrasion, minor skin injuries as a result of improper removal of the eczema or accidental scratching of a pimple while washing the head) also cause permanent and irreversible damage to the hair follicles on the scalp, so that no hair will grow in this place?
