Minoxidil is a widely recognized treatment for hair loss, including the thinning hair often seen in women during and after menopause. This medication is available in two forms: a topical application, which is FDA-approved for hair loss treatment, and an oral tablet, used off-label for the same purpose. The topical form can be purchased without a prescription, while the oral tablet requires a prescription.

How Minoxidil Works

Minoxidil is a vasodilator, and was originally used as a medication to lower blood pressure. An unexpected side effect of minoxidil was increased hair growth. The exact mechanism for promoting hair growth is not entirely understood. It’s believed to improve blood flow to the scalp and hair follicles, increasing the supply of nutrients and oxygen, which may stimulate hair growth and extend the growth phase of hair. It was initially formulated as a topical medication, but more recently, researchers have determined that low dose oral minoxidil is a safe and effective alternative to the topical form.

Potential Benefits of Minoxidil 

• Minoxidil has proven effective in stimulating hair regrowth in areas affected by thinning, with both its topical and oral forms showing positive outcomes.

Forms of Minoxidil and Their Approval Status

• Topical Minoxidil: This form is FDA-approved for treating hair loss and is available over the counter. It is applied directly to the scalp and comes in 2% and 5% concentrations.
• Oral Minoxidil: Although not FDA-approved for hair loss, oral minoxidil is prescribed off-label for this condition. It requires a prescription and is taken as a once-a-day tablet.

Timeline for Results

Individuals using minoxidil typically begin to see noticeable results within 3 to 6 months of consistent application or ingestion. It’s important to note, however, that to sustain these benefits, treatment must be continued indefinitely. A common initial response to minoxidil treatment is hair shedding, occurring within the first 2 to 8 weeks. This phase, which can be stressful,, is actually a positive indication that the hair follicles are preparing for new growth by releasing hairs that were no longer growing.

Usage and Considerations

Topical minoxidil should be applied to the scalp in the area of hair loss, adhering to the recommended dosage and frequency. Oral minoxidil is taken once daily, with the precise dosage determined by a healthcare provider.

Side Effects and Considerations

Topical minoxidil may cause scalp irritation or undesired hair growth in other body areas. Oral minoxidil can lead to more systemic side effects, such as changes in blood pressure or fluid retention, and should be used with caution, especially by individuals with heart conditions.You may also experience hair growth in areas other than the scalp. 

Conclusion

Minoxidil provides a hopeful solution for women dealing with hair loss during and after menopause. With options for both topical and oral use, it caters to different needs and preferences. Understanding the timeline for results and the commitment required to maintain these results is crucial for anyone considering minoxidil for hair loss treatment. As always, consulting with a healthcare professional is essential to choose the safest and most effective treatment plan.
