What is Baldness?
Baldness, another term for alopecia, is the loss of hair from the scalp. Losing a few strands is quite normal as they grow back in most people, but as age progresses this may not be the case.
Patterned hair loss is seen in both sexes after puberty. It is found that starting at the age of 35 years, two-third men experience baldness and 40% have noticeable hair loss. In India, 0.7% of the population experiences baldness.

It can appear in different forms depending on the factors causing baldness. It may cause sudden or slow baldness and may affect your scalp or the entire body. It can be permanent or temporary.
The major signs and symptoms include

How is it diagnosed and treated?
Male-type baldness is diagnosed by the appearance and pattern of hair loss and medical history. It is classified using the Hamilton-Norwood classification system, and the female type is classified using the Ludwig system. If there is scarring of the scalp, you may be referred to a dermatologist. In non-scarring alopecia, a small scraping of the lesion may be taken to test for fungal infection. Thereafter, a scalp biopsy may be performed if no clear cause can be detected. In diffuse hair loss, you may be told to do a serum ferritin and thyroid tests.
Treatment:
- Mainly, 5-alpha reductase inhibitors are used for hair restoration. A vast majority of the products contain snake oil because of the anti-frizz properties.
- Eliminating stress can help regrow hair.
- Laser therapy has also shown to provide good results by stimulating hair growth.
- Surgery can also reverse hair loss.
- Hair multiplication, which involves self-replenishing follicle stem cells multiplied in the lab and microinjected in the scalp, can help regrow hair.
- Nutritional supplements may be taken, as essential amino acids and other micronutrients are essential for proper hair growth.
Self-care:
- Change your hair products by consulting a trichologist.
