Doctor's Notes on Hair Loss (Alopecia)
- Scarring alopecia, which is irreversible hair loss characterized by damage to the underlying skin which results in scarring that destroys the hair follicle and its potential for regeneration; and
- non-scarring alopecia, which is a common and potentially reversible type of hair loss.
Common causes of hair loss include
- male pattern baldness,
- female-pattern baldness,
- telogen effluvium (occurs mostly in females, especially post pregnancy),
- alopecia areata,
- certain medications and
- chemotherapy drugs,
- poor nutrition and strict dieting, and
- certain types of weight loss (bariatric) surgery.
Hair loss is a symptom itself that is usually noticed by individuals when they look at themselves in a mirror or when others bring it to their attention. Hairs on the pillow in the morning or more hairs in the hairbrush or comb can be signs of hair loss. Women may notice less hair in their ponytails or widening parts.
