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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyStudy: 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.
