The Bottom Line

MSM shows very early and limited promise for hair thinning based on animal studies, but there are no human clinical trials to support its use for this purpose.

Only 2 studies exist, both showing positive results but neither involving human participants
MSM is a sulfur-rich compound that theoretically supports keratin and collagen formation
One animal study showed potential benefits when MSM was combined with minoxidil
Human clinical trials are needed before MSM can be recommended for age-related hair thinning
