- Hair loss in men is usually androgenetic alopecia, also called male-pattern hair loss.
- It often begins with a receding hairline or thinning crown and progresses slowly over years.
- Ordinary hereditary loss usually causes no pain, pus, scarring or sharply defined round bald patches.
- Redness, burning, scales, crusts, hair breakage or loss of eyebrows and beard suggest another cause.
- Early assessment particularly matters if uncertain between ordinary pattern loss and scarring or systemic causes such as thyroid disease, anaemia or a medicine side effect.
- Do not suddenly start products or use them without guidance if you take other medicines, plan to have children or have scalp disease.
