The Claim

After 12 weeks of daily 5-gram creatine supplementation in healthy young male resistance-trained individuals, there were no significant changes in hair follicle density, terminal hair rate, vellus hair rate, follicular unit count, or cumulative hair thickness.

Description
1 study reviewed
In plain English

Daily supplementation with 5 grams of creatine for 12 weeks did not change hair follicle density, the proportion of thick or fine hairs, the number of hair units, or total hair thickness in healthy young men who train with weights.

See the scientific wording

No significant changes in hair follicle density, terminal hair rate, vellus hair rate, follicular unit count, or cumulative hair thickness were observed after 12 weeks of 5-gram daily creatine supplementation in healthy young male resistance-trained individuals, indicating no measurable effect on hair follicle structure or growth.

Why this might work

Taking creatine every day does not change how hair follicles grow, how many hairs are present, or how thick the hairs become because it does not affect the cells or signals that control hair growth.

  1. Study: Does creatine cause hair loss? A 12-week randomized controlled trial

    This study gave 5 grams of creatine daily to weightlifters for 12 weeks and checked their scalp hair before and after — nothing changed. Their hair didn't thin, fall out, or grow differently than those who took a placebo.
