🧴 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.

📊 What It’s Used For

Minoxidil 5% is FDA-approved for:

• Male pattern baldness

• Female pattern hair loss (FPHL)

It's also commonly used off-label for:

• Beard growth

• Eyebrow thickening

• Telogen effluvium support (post-stress shedding)

📌 How to Use Minoxidil 5%

General guidelines:

• Apply 1 mL twice daily to thinning areas (or once daily for foam or if sensitive — still effective for many).

• Ensure the scalp is dry before use.

• Do not wash for 4 hours after application.

• Avoid getting the product on the face unless intentionally applied for beard growth.

💡 Who Gets the Best Results

• Younger users

• Hair loss within the last 5 years
