Topical Minoxidil 5%

Topical Minoxidil

What It Is

Minoxidil is a topical hair growth medication originally developed as a blood-pressure drug. When applied to the scalp, it promotes hair growth and slows hair loss.

Available as:

• 5% solution

• 5% foam (often better tolerated)

• Higher concentrations (10-15%) exist but are not FDA-approved.

How It Works

Minoxidil acts locally on the scalp and supports hair growth through multiple mechanisms:

1. Increases blood flow to hair follicles

It widens blood vessels, improving oxygen and nutrient delivery to follicles.

2. Prolongs the anagen (growth) phase

Hair stays in the growing phase longer - thicker and longer hair.

3. Enlarges miniaturized follicles

Helps reverse follicle shrinkage seen in androgenetic alopecia (male/female pattern hair loss).

4. Converts vellus hairs to terminal hairs

Thin “peach-fuzz” hairs gradually become thicker, pigmented terminal hairs.
