Topical Minoxidil 5%
First-Line Hair Growth Treatment

How minoxidil works

Minoxidil was originally developed as an oral blood pressure medication; researchers noticed patients growing hair as a side effect. The topical form was developed specifically for hair loss. It works by prolonging the anagen (growth) phase of the hair cycle, enlarging miniaturized follicles, and increasing local blood flow to the scalp. It does not address DHT — which is why combining it with finasteride produces stronger results.

Who it's for

Minoxidil is FDA-approved for androgenetic alopecia in both men (5% concentration) and women (2% and 5%). It is typically first-line for women because finasteride is contraindicated in women of childbearing potential. For men, it's most effective combined with finasteride.

Formulations available

• Minoxidil 5% topical solution: standard treatment, applied twice daily
• Minoxidil 5% foam: easier to apply, less likely to drip
• Compounded minoxidil + finasteride combo: a single-bottle option for men that combines two commonly used hair-loss medicines
• Compounded minoxidil + finasteride + tretinoin 3-in-1: tretinoin has been studied as a possible way to improve minoxidil response in some people; evidence is limited
• Custom concentrations: higher compounded strengths may be considered by your physician for patients who plateau on 5%

Compounded formulations are compounded preparations, not FDA-approved (there is no FDA-approved topical finasteride in the US). They are prepared by a licensed 503A compounding pharmacy (for example Hallandale Pharmacy or Valiant Compounding Pharmacy); the dispensing pharmacy is named on your prescription label.

Timeline and expectations

• Weeks 2–8: possible initial shedding phase (new hair pushing out old)
• Months 3–4: reduced shedding, early regrowth
• Months 6–12: visible density improvement
• Ongoing: continued use maintains results; stopping leads to loss within 3–6 months

Side effects

Most common: scalp irritation, dryness, itching. Less common: unwanted facial hair growth (more frequent in women), dizziness, headache (rare with topical). Oral minoxidil at low dose (off-label for hair loss) is sometimes used by physicians as an alternative; discuss with your doctor.

Pregnancy and childbearing potential: minoxidil is not recommended during pregnancy or breastfeeding. Combination formulas that contain finasteride are not for anyone who is pregnant or may become pregnant, who should also avoid handling them; tretinoin should be avoided in pregnancy or when planning pregnancy.

Pricing

• Minoxidil 5% topical: $29/month care fee
• Oral finasteride 1 mg with minoxidil 5%: $29/month care fee
• Medication is not included: sent to a pharmacy that works for you: a local retail pharmacy such as Walmart, or a low-cost online pharmacy. You pay the pharmacy directly; YourMDRx Savings shows cash prices and coupons.
• Compounded topical finasteride + minoxidil, with or without tretinoin: $29/month care fee + compounded add-on. Compounded medication add-on: once your physician selects the compounding pharmacy, you receive a final price proposal (medication, shipping and our care fee) to accept before anything is made. You make one payment to YourMD for that proposal; the licensed compounding pharmacy prepares and ships it. Compounded medications are not FDA-approved.
