Minoxidil is a well-known medicine used to treat high blood pressure and hair loss in both males and females. The brand name for Minoxidil is Rogaine.

Minoxidil acts as a vasodilator, available in both oral and topical forms. While the oral tablet is used under prescription for high blood pressure, the topical liquid and foam are commonly used over the counter to treat hair thinning and male or female pattern baldness.

What are the Uses of Minoxidil?

This medicine is mainly used for promoting hair growth and is sometimes prescribed for blood pressure management.

Conditions Minoxidil Treats

  • Male pattern baldness (vertex area only)
  • Female pattern hair loss (2% solution)
  • High blood pressure (oral form, by prescription)

Secondary Uses of Minoxidil

  • Occasionally used in combination therapy for resistant hypertension.
  • It may help in hair thickening when applied consistently.

Minoxidil for Men

Minoxidil for men is used to treat male pattern baldness, especially at the crown of the scalp. The 5% solution or foam is often preferred for its stronger effect. It works by improving blood supply to hair follicles, promoting new hair growth. Regular application is key for visible results. Results may vary by individual.

Minoxidil for Women

Minoxidil for women is commonly used to treat thinning hair or female pattern hair loss. It helps improve hair growth by increasing blood flow to hair follicles. The 2% topical solution is usually recommended. Consistent use may lead to thicker, healthier hair over time. Always use as directed by a healthcare provider.

How Does Minoxidil Work (Mechanism of Action)?

Minoxidil 5 works by relaxing and widening blood vessels, which improves blood flow to hair follicles and helps lower blood pressure.

As a vasodilator, Minoxidil increases blood supply to the scalp, revitalizing hair follicles and stimulating growth. In its oral form, it relaxes blood vessel walls, helping reduce blood pressure.
