Q: Are there DHT blockers that are sold in the pharmacy over the counter? — C.C., — Fairfield County, Connecticut
A: The only effective DHT blockers are finasteride (Propecia, Proscar) and dutasteride (Avodart).
These medications require a doctor’s prescription and are not sold OTC. Nizoral is a topical shampoo for seborrhea (a type of dandruff) that is sold over the counter, but it is not effective in treating hair loss.
