Losing 50 to 100 hairs a day is normal. However, if shedding is heavy, some areas look thinner, or your hair feels finer, it is worth seeing a dermatologist. The earlier hair loss is treated, the better the results.
Most common causes
- Androgenetic alopecia: the most common type, in men (receding hairline and crown) and women (thinning along the parting). It has genetic and hormonal components.
- Telogen effluvium: sudden diffuse shedding a few months after severe stress, illness, childbirth, a strict diet or iron deficiency. It is usually temporary.
- Alopecia areata: round bald patches that appear suddenly, caused by the immune system.
- Scarring alopecias: less common, but they need early diagnosis and treatment to prevent permanent loss of hair follicles.
How it is diagnosed
In clinic I examine the scalp with trichoscopy (dermoscopy of the hair) and, if needed, order a blood test to rule out causes such as iron deficiency or thyroid problems.
Treatment
- Topical and oral treatments tailored to each type of hair loss, such as minoxidil or anti-androgens.
- Hair mesotherapy, including dutasteride in selected cases of androgenetic alopecia.
- Injections for alopecia areata.
- Correcting nutritional deficiencies where present.
Results of hair treatment are assessed after 3 to 6 months, so consistency is essential.
If you notice you are losing hair, book an appointment: an accurate diagnosis is the first step.
