Minoxidil is a popular solution for hair regrowth, but it's important to be aware of minoxidil side effects before starting treatment. Common side effects include scalp dryness, itching, flaking, or irritation. Some people may also experience increased hair shedding initially, which is usually temporary and part of the hair growth cycle. Less common but more serious minoxidil side effects can include dizziness, unwanted facial hair growth, rapid heartbeat, or swelling in the hands or feet. These side effects vary from person to person and may depend on how sensitive your skin or scalp is. It's important to apply minoxidil only to the affected areas and follow the recommended dosage. If you notice any unusual symptoms, it's best to stop using the product and consult a healthcare professional. Understanding these minoxidil side effects can help you make an informed decision and use the product more safely and effectively.
