Will MSM Improve Hair Growth?

Some readers report that taking the dietary supplement MSM can improve hair growth and make it fuller and thicker.

Is there anything you can take to improve hair growth? Some supplement manufacturers claim that their nutraceuticals can help achieve thick, healthy hair. Our readers embrace one popular supplement that is usually promoted to ease joint pain. 

MSM to Improve Hair Growth? 

Q. Years ago, I read in your column that MSM supplements (without glucosamine) helped hair stay full and thick. I started taking it about 2002, and I have pretty, thick healthy hair at age 57. I definitely saw an improvement in my hair within a few months of starting the supplement. Thank you for your good advice!

What Is MSM?

A. MSM stands for methylsulfonylmethane. It is a naturally occurring compound with well-established anti-inflammatory activity. A review of the medical literature concluded that MSM can ease the pain and stiffness of arthritis (Nutrients, March, 2017). Most people who take it are using it for that purpose.

Some preliminary research suggests that this dietary supplement alone or in combination with other compounds may be helpful for skin quality and texture (Journal of Clinical and Aesthetic Dermatology, Apr. 2019). There are hints it might benefit hair, but we could find no data to support its ability to improve hair growth in humans. Some people speculate that MSM can be beneficial for hair health because it is a good source of sulfur. Until there are clinical trials, however, this remains hypothetical.

Side Effects of MSM:

Fortunately, most people seem to tolerate MSM well, and it has a good safety profile (Complementary Therapies in Medicine, Aug. 2019). Doctors have reported only a few adverse reactions. In one case, a patient developed a rash similar to eczema (Australasian Journal of Dermatology, Nov. 2016). Another patient, a 35-year-old woman, developed glaucoma with acute angle closure (Journal of Glaucoma, April/May 2015). Although such problems appear to be rare, they remind us that even popular supplements may have unpleasant side effects.

What exactly is the natural source of MSM? Is it a mineral? How does it work, what form is it in, and where is it available?

Here’s what we found in a search:

I use liquid MSM drops in my eyes as a dry eye treatment. Of all the treatments I tried — prescription drops, warm compresses, etc. — liquid MSM drops have worked the best.

I have been taking MSM since I turned 42 when I developed popping in my knees, stiffness, and the onset of arthritis in my hands. Now, about 25 years later, I have a full head of hair that barely has any gray and have avoided knee surgery. If I miss taking it for a few days, my knees start hurting and popping. I keep some liquid msm in the fridge for such emergencies. I do supplement with biotin for healthy nails.

I found that sea buckthorn is far more helpful in promoting thicker, shinier hair and stronger nails.

Read the reviews on products containing MSM and other MSM products, and you will see complaints about it upsetting the stomach to the point where it has to be stopped. It did it to me, and I had to stop it immediately.

If a person has an allergy to sulfa drugs, will MSM cause an allergic reaction?

My doctor suggested Biotin supplements for hair growth, and that has worked well for me.

I read that MSM could be helpful for weak, peeling fingernails, so added MSM to my supplements. To my surprise, it enhanced the effect of my rosacea treatment. It did not eliminate the need for Metronidazole topical cream, but the MSM did make a difference. An extended time without the MSM demonstrated a worsening of the rosacea.

Reading online review comments, and it also may help with neuropathy pain and inflammation. Just ordered some!
