Quite common and present at birth, congenital atrichia usually appears as small spots where the follicle does not grow hair.

Generalised hair loss brought on by aggressive brushing, styling or hair weaving. It is also caused by prolonged stress or tension (pulling) created by overly tight weaving, extensions and corn rowing styling techniques placed on weak hair. It can result in permanent hair loss. Extreme heat styling and strong chemical services like beaching, colouring and permanent waving can also cause temporary rapid hair loss.

The unnatural and irresistible urge to pull out one’s own hair caused by certain psychological disorders. It’s estimated that 8 million Americans are affected by this compulsive action. These disorders can actually cause people to impulsively pull out their hair in large clumps. There are prescribable drugs that have been effective in treating this condition. However, hair re-growth is not always successful.

A patchy hair loss caused by Trichophyton Tonsurans, a fungal infection of the scalp. This common scalp fungus causes hair to break off at the scalp. Flaking and scaling on the scalp is a symptom of tinea capitis. If treated early, hair loss can be minimised.

A generalised hair loss that occurs after physical trauma, emotional stress, or thyroid abnormalities — usually within 2 or 3 months of incident. High levels of stress, surgery, infections, high fevers and sudden hormonal level changes (like from childbirth) can trigger this form of hair loss in both men and women.

Hair loss caused by the radiation and chemotherapies used to treat cancer. Radiation and chemicals used in cancer treatments work to kill the cancer and often cause hair to stop growing as well: They are designed to kill cells that reproduce very rapidly like those produced in the hair papilla.
