Types and causes of hair loss
Hair loss can have many causes. The most common is androgenetic alopecia (male and female pattern hair loss). Other forms include telogen effluvium (temporary, often triggered by stress, illness, or pregnancy), alopecia areata (patchy loss, autoimmune), and scarring alopecias. Medical conditions such as iron deficiency and thyroid disorders may also contribute.
Identifying the pattern and likely cause is the first step. This usually involves a careful history and some basic blood tests. In some cases, specialist assessment by a dermatologist is needed.
How a telehealth GP can help
A NewDoc GP can take a thorough history, discuss the pattern of hair loss, review medications that can contribute, order relevant blood tests, and discuss treatment options that may be appropriate in your case. If specialist assessment is needed, your GP can issue a dermatologist referral.
Because hair loss often needs visual assessment of the scalp, an in-person review may be recommended in some situations. Your GP will let you know.
