Hair Loss in Men
Hair loss accompanied by changes of the scalp may indicate a group of conditions known as scarring hair loss. Hair falls out because of damage to the hair follicles (the tiny holes in the skin from which hairs grow).
An allergic or toxic reaction to a hair product, such as hair dye or a new shampoo, might cause this.
