MSM for Hair
A sulfur-rich compound that may donate sulfur to keratin, strengthening hair and boosting growth.
Also known as: Methylsulfonylmethane • Dimethyl Sulfone
Overview
Methylsulfonylmethane (MSM) is an organic sulfur-containing compound found naturally in some plants and animals. Sulfur is a critical building block for collagen and keratin, the primary proteins that make up hair, skin, and nails. By providing a bioavailable source of sulfur, MSM is thought to strengthen the disulfide bonds in keratin, making hair more resilient. It may also help lengthen the anagen (growth) phase of the hair cycle.
Key Benefits
Provides Sulfur for Keratin
MSM is a rich source of sulfur, which is a key component of the amino acid cysteine. Cysteine is crucial for forming the strong disulfide bonds that give keratin its strength and durability.
May Lengthen the Anagen Phase
Some research suggests that MSM can prolong the anagen (growth) phase of the hair cycle, leading to longer and thicker hair over time.
Reduces Inflammation
MSM has anti-inflammatory properties that can help soothe scalp conditions and create a healthier environment for hair growth.
Dosage & How to Take
Doses for hair health typically range from 1 to 3 grams per day.
| Purpose | Dose | Notes |
|---|---|---|
| Hair, Skin, and Nail Support | 1-3 grams/day | Start with 1 gram and gradually increase to assess tolerance. Can be mixed with water or juice. |
| Joint Health and Inflammation | 3-6 grams/day | Higher doses are often used for managing joint pain and arthritis. |
Best Time to Take
Best to split the dose (e.g., morning and evening) to maintain stable levels.
With or Without Food
Can be taken with or without food. Taking it with a source of Vitamin C may enhance absorption and utilization.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Distilled MSM (e.g., OptiMSM) | High | Purity and avoiding potential contaminants. | Multi-stage distillation is considered the gold standard for producing pure MSM, free from heavy metals and impurities. |
| Crystallized MSM | Good | General use. | A common form, but may not have the same purity guarantee as distilled MSM. |
Side Effects & Safety
Common
- Generally well-tolerated.
Rare
- May cause mild digestive issues like bloating or diarrhea in sensitive individuals, especially at higher doses.
- Headaches.
Contraindications
- None well-documented, but those on blood thinners should consult a doctor.
Interactions
MSM is considered very safe and does not have significant known drug interactions.
Scientific Research
The Effect of Methylsulfonylmethane on Hair and Nail Health
A 2019 study on women showed that taking MSM (at 1g or 3g per day) resulted in statistically significant improvements in the appearance and condition of hair and nails as rated by both subjects and experts.
