Alopecia is a condition that shows hair loss due to many reasons, one of which is medication. Such a condition is known as Drug-induced alopecia and it can influence any part of the scalp or body. The extent of hair loss depends on the dosage and duration of medication that the person is taking. No doubt, extensive hair loss will require hair loss treatment. You may require a hair transplant after facing hair loss due to medication. 

Signs of drug-induced alopecia

Drug-induced alopecia is often seen after 3 months of starting a medication. The pattern will generally start with thinning hair, followed by patches of hair loss.

Stopping the intake of the medication is the best way to treat drug-induced alopecia. However, people should consult a doctor before withdrawing from the medication.
