Oral minoxidil for hair loss is typically prescribed at a dose of 1 mg daily, as this dose has been shown to be effective and safe in improving hair density and diameter, with significant improvement in hair growth after 6 months of treatment 1. When considering oral minoxidil for hair loss, it is essential to weigh the potential benefits against the potential risks and side effects. The medication works by widening blood vessels and increasing blood flow to hair follicles, prolonging the growth phase of hair. Some key points to consider when prescribing oral minoxidil for hair loss include:
- Starting with a low dose, such as 1 mg daily, and adjusting based on response and side effects
- Monitoring patients for side effects, including fluid retention, increased heart rate, and lowered blood pressure
- Regular follow-up appointments to assess efficacy and adjust dosing as needed
- Patient education on the importance of continued treatment to maintain results, as hair loss will resume upon discontinuation
- Consideration of alternative treatments, such as topical minoxidil or low-level laser therapy, for patients who experience side effects or have poor response to oral minoxidil According to a study published in the Journal of cosmetic dermatology, 1 mg daily oral minoxidil may be as effective and safe as standard topical minoxidil in female and male pattern hair loss 1. Another study published in the Journal of the American Academy of Dermatology found that low-dose oral minoxidil has a good safety profile, with systemic adverse effects being infrequent and only 1.7% of patients discontinuing treatment due to adverse effects 2. It is also important to note that oral minoxidil should only be used under medical supervision, and pregnant women or those with certain cardiovascular conditions should avoid it. In terms of dosing, a review of oral minoxidil as a treatment for hair disorders found that different dosing regimens have been utilized, ranging from 0.25 to 5 mg daily, with women requiring lower doses and men requiring higher doses for maximal efficacy 3. Overall, oral minoxidil can be a effective treatment option for hair loss, but it is essential to carefully consider the potential benefits and risks and to monitor patients closely for side effects.
