Hair loss occurs in males, females, children and adults. Hair loss can be an isolated problem or associated with another disease or condition. It can be temporary or permanent, depending on the cause. Hair loss can be due to decreased growth of the hair (anagen hair loss), increased shedding of the hair ( telogen hair loss), conversion of thick terminal hairs to thin vellus hairs (pattern hair loss), congenital or acquired hair shaft abnormalities and inflammatory skin disease that damages or destroys the hair bulb.
Male Pattern Hair Loss
The term “common baldness” usually means male pattern or permanent pattern baldness, scientifically known as androgenetic alopecia as the role of androgens in its occurrence is well understood. It usually begins at the age of 30 but can occur at any age after puberty. Men who have this type of hair loss usually inherit the trait. In this type of baldness, hair loss typically results in a receding hairline and loss hair on the top of the head.
Female pattern hair loss
The most common type of hair loss seen in women is androgenetic alopecia, also known as female pattern hair loss. But as in men, it does not have to be complete hair loss. There is marked thinning of hair on the top known as Christmas tree pattern.
