What is topical minoxidil?

Topical minoxidil is a medication used to treat hair loss and promote hair growth. It works by increasing blood flow to the scalp, which stimulates new hair growth. The most common form of topical minoxidil is a foam or liquid applied directly to the scalp twice daily.

What is topical minoxidil used to treat?

Minoxidil is a topical medication used to treat hair loss and promote hair growth in both men and women.

Minoxidil will not cure baldness, but it can help you keep the hair you have while preventing further balding. In addition, minoxidil has been shown to encourage hair growth. It may take several months for hair growth to occur, and the regrown hair will fall out if you stop using minoxidil.

How does topical minoxidil work?

Minoxidil belongs to a class of medications known as vasodilators. These drugs work by opening blood vessels, allowing blood to flow more freely throughout the body. This increased circulation delivers more oxygen and nutrients to the follicles, resulting in thicker and healthier hair growth over time.

Minoxidil also decreases the resting phase of hair follicles and increases the growth phase.

How do I use topical minoxidil?

Topical minoxidil is available in the following forms:

• Solution
  
• Foam
  
  

The dosage and frequency of use depend on the condition being treated, its severity, and how you respond to the medication.

Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or frequency of use without consulting your provider.

How long until I see results?

Topical minoxidil is used to treat hair loss and promote hair regrowth. The effects can be noticeable within a few months, but it may take up to four months or longer to see significant improvement.

Continue using topical minoxidil even if you start seeing results. Regular use is crucial for the treatment's effectiveness.

Are there any other uses for topical minoxidil?

While topical minoxidil is primarily used to treat hair loss, healthcare providers may prescribe it off-label for other conditions, such as promoting hair growth in areas affected by alopecia areata.

Discuss any alternative uses of topical minoxidil with your healthcare provider.
