Either consciously or unconsciously, self-inflicted damage to hairs may be a cause of hair loss in some individuals. There are two types of self-induced hair loss:
Trichotillomania – This type of hair loss is commonly seen in childhood, more frequently in girls than in boys. The people who compulsively and continuously pull or pluck their hairs experience trichotillomania. This implies that this disorder has a strong psychological basis.
Traction alopecia – This type of hair loss is caused by the continuous and excessive pulling and tension of the hair due to some types of hair styling or hair systems fixed on the hair itself.
