I have been using minoxidil 10% almost 4 weeks, i started with 5%, i see thin hair growing in bald area but are thin, should i go for derma roller?

See a dermatologist: At age 22, you may be experiencing hair loss due to genetics, or anabolic steroid abuse. A more complete approach to your hair loss problem, irregardless of the cause, would be Minoxidil 2.5 mg orally daily, and Proscar 5 mg tablets. You need to quarter the Proscar tablets via a pill cutter from your local pharmacy, and this will equal 1.25 mg of finasteride, i.e. Propecia.
