Stronger, longer hair? Doctor comments on hair supplements

Supplements promise to strengthen and accelerate hair growth , but according to hair medicine specialist Alexandra Lopes , they only work when nutritional deficiencies are identified. Beyond that, indiscriminate use can pose more risks than benefits.

One of the most popular compounds in these products is biotin, a B-complex vitamin . The expert clarifies that it can indeed help with hair growth and strengthening —but only in specific cases. "Biotin is effective when there's a deficiency confirmed by tests. If levels are normal, supplementation won't yield significant results," she states.

Another point of concern is consumption without medical advice. According to Alexandra, excess vitamins can overload the body and mask health problems. "The indiscriminate use of supplements can cause side effects and make diagnosis difficult. It's a risk that people often don't consider."

Before considering capsules, it's essential to consider what's on your plate. The Onne Clinic specialist emphasizes that the foundation of hair health lies in nutrition . "A diet rich in iron, zinc, protein, and B vitamins provides the nutrients hair needs to grow strong and resilient," she explains.

According to Alexandra, signs such as persistent hair loss, thinning, frequent breakage, brittle nails, and skin changes may indicate nutritional deficiencies. "These symptoms should be evaluated by a professional. Correct diagnosis is essential for effective and safe treatment," she concludes.
