Oral minoxidil, originally developed as a blood pressure medication, has been found to have a side effect of promoting hair growth. This led to its use as a treatment for hair loss, particularly male and female pattern baldness. While topical minoxidil (applied directly to the scalp) is more commonly used for hair loss, some individuals may opt for oral minoxidil if topical treatments are ineffective or not well tolerated.
Studies have shown that oral minoxidil can be effective in promoting hair growth in people with certain types of hair loss, including androgenetic alopecia (male and female pattern baldness) and alopecia areata. However, oral minoxidil carries a higher risk of side effects compared to topical minoxidil, including low blood pressure, fluid retention, and heart palpitations. Therefore, it is typically prescribed at lower doses and with careful monitoring by a healthcare professional.
It’s important for individuals considering oral minoxidil to discuss the potential benefits and risks with their healthcare provider to determine if it’s the right treatment option for them. As with any medication, results can vary from person to person, and it may take several months of treatment to see noticeable improvements in hair growth.
