A Word From Our Expert
— Dr. Jonathan Rick
Like all treatments, hair regrowth approaches require knowledge of costs and benefits. Thankfully most treatments are very safe, but we still need to strike an acceptable balance between financial cost and known clinical efficacy. I usually start with topical minoxidil and then escalate to topical finasteride if needed. I then discuss Nutrafol or similar products in addition to minoxidil and finasteride.”
