Which formula should I use?
Most doctor sites suggest the 2% or 5% solution and women the 2%. I’m not sure on local regulations on their use, but the 12.5% minoxidil or the 12.5% minoxidil with Azelaic Acid or the 15% also seem popular. Availability of the 12.5% and 15% minoxidil vary depending on your location. You can buy 12.5% minoxidil with Azelaic Acid online (or the 15% minoxidil) and in the pharmacy (if they sell it in your country).
And of course, you should ask a doctor! If you’re lucky to be insured, the visit could cost you from $10 – $100 (if you live in the US) – without insurance a dermatologist visit could cost as much as $350. Online consultations for prescription medications are common, legal and a cheap alternative to an in-person doctor visit if you live too far from a dermatologist or don’t have insurance.
