Long-time readers know that I think that the Doctors of Pharmacology who publish the Natural Medicines Comprehensive Database have one of the best, if not the best (evidence-based, trustworthy, and medically reliable) internet resources for natural medications (herbs, vitamins, and supplements). This month they’ve sent prescribers a warning about MSM for hair loss.
Methylsulfonylmethane (MSM) is best known as a remedy for osteoarthritis. But it’s now showing up in products promoted for hair loss including:

• TriMedica Pure MSM Shampoo,
• Hair Loss Support Liquid,
• Hair Loss Alopecia Shampoo,
• Sulfur Plus, and many more.

The thinking is that MSM contains sulfur, which is an element important for hair growth. And, some people who try it often say that it works.
But, the NMCD experts tell us prescribers to “explain to patients that there is no reliable scientific evidence that MSM is effective for increasing hair growth.”
If this changes, I’ll let you know. And, in the meantime, it might not hurt to try, but there’s no evidence that it will help.
