Nutrition, Oral Supplements, And Alternative Therapies For Hair Loss

January 2026 in “ Updates in clinical dermatology ”

Selena R. Pasadyn, Omair Irfan, Melissa Piliang

TLDR Proper nutrition and alternative therapies can help manage hair loss.

The document reviews the impact of nutrition, supplements, and alternative therapies on hair loss, emphasizing the importance of micronutrients like zinc, selenium, iron, and vitamins. Zinc supplementation benefits alopecia areata patients with low zinc levels, while iron deficiency is linked to hair loss in women. Vitamin D may also influence hair health. Although biotin is popular, its effectiveness is debated. Alternative treatments such as tocotrienol, rosemary oil, and melatonin show potential in promoting hair growth. Addressing nutrient deficiencies and exploring alternative therapies are crucial for managing hair loss.
