8 Hair Loss Types, Symptoms, Diagnosis, Causes And Treatments

1. Androgenetic Alopecia - Most Common

Androgenetic Alopecia

When hair loss is related to androgens and genetics, it is known as Androgenetic Alopecia, or more commonly just balding. It affects roughly 50% of men by age 50 years, and perhaps as many women older than 40 years by menopause.

2. Telogen Effluvium - Second Most Common

Telogen Effluvium

It is a scalp disorder which causes temporary hair loss due to shedding of Telogen Phase hair after some shock to the system. Unlike Androgenetic Alopecia, this condition causes diffuse/generalised thinning, instead of localised baldness.

5. Traction Alopecia

Traction Alopecia

6. Folliculitis Alopecia - Scarring Alopecia

Folliculitis Alopecia

Severe folliculitis can cause permanent hair loss and scarring, the result of active destruction of the hair follicle and the follicle is irreparably damaged and replaced by fibrotic tissue.
