Alexandre Costa, endocrinologist: "Minoxidil helps with your hair, but it lowers your blood pressure."

Endocrinologist Alexandre Costa explained in a recent interview that one of the most effective treatments for alopecia , minoxidil, was originally used as a medication for hypertension. Its use, he points out, can be an advantage or a risk depending on each patient's profile : if blood pressure is high, it helps; if it's low, it can cause dizziness and discomfort. He also warns that this drug can promote hair growth in other, unwanted areas of the body.

Throughout the conversation, Costa emphasized that there are no natural remedies with proven effectiveness for halting baldness. Although some compounds are frequently mentioned, their actual impact is limited. According to the specialist, the only methods with consistent results are pharmacological, with oral, topical, or mesotherapy options, each with its advantages and disadvantages.

In the case of minoxidil, the oral form is more effective but also carries more side effects. The topical version acts only on the applied area and is less potent, while mesotherapy—injections into the scalp —is painful, expensive, and less effective , making it, in the words of the endocrinologist, a formula for "patient loyalty" rather than an optimal solution.

Costa knows what he's talking about, having undergone two hair transplants himself after losing his hair at an early age . He acknowledges that medication and the transplants have allowed him to regain his appearance, but warns that neglecting treatment or combining it with unhealthy habits—such as certain competitive bodybuilding regimes—can lead to the reversal of the results achieved.

Beyond hair, the endocrinologist addressed the importance of taking care of metabolism and body composition. He emphasized that protein is the most underrated macronutrient and that maintaining a good level of muscle mass helps not only with aesthetics but also with metabolic health and fat burning. In his experience, many of the problems he sees in consultations stem from bad habits repeated daily rather than from occasional excesses.

Regarding mental health, Costa sent a clear message: focusing only on the physical is a mistake. For him, psychological well-being, meditation, and personal development are just as important as nutrition or exercise. He believes that giving to others, sharing knowledge, and helping without expecting immediate benefits ultimately results in a more fulfilling life.

Finally, he offered some straightforward advice for those considering treating baldness: educate yourself and personalize your treatment. What works for one person may not be safe for another, and medical supervision is key to avoiding major problems while trying to maintain—or recover—your hair.
