Why people think creatine might help hair

Hair follicles are among the most metabolically active tissues in the body, and creatine helps cells recycle energy. That's led to speculation, and to some hair products listing creatine as an ingredient. But a plausible idea isn't evidence, and no clinical trial has shown creatine regrows hair.

What the research shows

In the 2025 randomized trial, men taking 5 g a day for 12 weeks had no change in hair density, follicular units or thickness compared with placebo. Good news if you were worried about loss; no help if you were hoping for growth. See the study.

What actually helps hair grow

• Minoxidil: FDA-approved, stimulates growth.
• Finasteride: lowers DHT and often produces some regrowth.
• Ketoconazole shampoo: supports a healthy scalp.
• Laser caps: FDA-cleared low-level light therapy.
• Hair transplant: moves permanent follicles to bald areas.

Supporting your hair with nutrition

Enough protein, iron, zinc and vitamin D supports normal hair growth, and correcting a true deficiency can reduce shedding. Supplements beyond that, including creatine, biotin in people who aren't deficient and "hair gummies", have weak evidence for regrowth.
