From the Guidelines
There is no conclusive evidence to suggest that creatine supplementation directly causes hair loss, and individuals can safely use creatine without significant concern for hair loss as a side effect. While some studies have raised concerns about the potential for creatine to increase dihydrotestosterone (DHT) levels, which is associated with male pattern baldness, the current evidence is limited and inconclusive 1. The study by Leonberg-Yoo et al, published in 2020, discusses the potential nephrotoxicity of various dietary supplements, including creatine monohydrate, but does not provide any evidence linking creatine to hair loss 1. In fact, the study highlights the importance of considering the potential effects of dietary supplements on kidney function, particularly in individuals with pre-existing kidney disease, but does not mention hair loss as a potential side effect of creatine supplementation.
Some key points to consider when evaluating the relationship between creatine and hair loss include:
- The lack of strong scientific evidence supporting a direct link between creatine supplementation and hair loss
- The potential for creatine to increase DHT levels, which may contribute to male pattern baldness, but this finding has not been consistently replicated in larger studies
- The importance of considering individual factors, such as genetics, age, and hormonal changes, which can influence hair loss
- The need for further research to fully understand the potential effects of creatine supplementation on hair loss
It is essential to note that the study by Leonberg-Yoo et al 1 provides valuable insights into the potential effects of dietary supplements on kidney function, but does not provide any conclusive evidence on the relationship between creatine and hair loss. Therefore, individuals can safely use creatine supplementation without significant concern for hair loss as a side effect, but should always consult with a healthcare provider if they have concerns about potential side effects or interactions with other medications.
From the Research
Creatine and Hair Loss
- There is no direct evidence that creatine causes hair loss, as shown in a 12-week randomized controlled trial 2.
- The study found no significant differences in dihydrotestosterone (DHT) levels, DHT-to-testosterone ratio, or hair growth parameters between the creatine and placebo groups 2.
- The results of this study provide strong evidence against the claim that creatine contributes to hair loss 2.
Alternative Supplements for Hair Loss
- Saw palmetto, a botanical extract with antiandrogenic properties, has been shown to have positive effects on hair regrowth in patients with androgenetic alopecia (AGA) and telogen effluvium 3.
- A nutritional supplement containing omega 3&6 and antioxidants has been found to improve hair density and reduce telogen hair percentage in women with female pattern hair loss 4.
- Biotin, a popular hair supplement, has limited research to support its efficacy in healthy individuals, and its utility as a hair supplement is not supported by high-quality studies 5, 6.
