Curly hair loves care - but let’s be honest, finding what actually works can feel like trial and error. One ingredient that’s been trending in the natural hair community is MSM powder. But what is it, and is it really worth the hype?
Short for methylsulfonylmethane, MSM is a natural sulphate compound found in plants, animals, and even our bodies. Sulphate is key to keratin - the protein that gives your hair structure and strength. So, it makes sense that MSM is gaining attention for its potential to support longer, stronger, healthier hair.
What is MSM powder and how does it work?
MSM is an organic form of sulphate that helps your body produce collagen and keratin - two proteins that are essential for healthy hair, skin, and nails. While it’s more commonly used in joint health supplements, many people take it to support hair growth.
The theory is that MSM helps lengthen the anagen (growth) phase of the hair cycle, giving your strands more time to grow before shedding. It may also support scalp health by reducing inflammation and oxidative stress - two things that can get in the way of growth.
Scientific studies are still catching up, but within the curly hair community, MSM has earned a rep as a go-to for encouraging thicker, stronger curls.
Benefits of MSM powder for curly hair
- Supports hair growth – MSM may help extend the growth phase of hair, leading to longer strands over time.
- Improves scalp health – Its anti-inflammatory properties can soothe and balance the scalp.
- Strengthens strands – As a natural sulphate, MSM supports keratin production for stronger, more resilient curls.
- Helps with moisture retention – Stronger hair holds hydration better, keeping curls juicy instead of dry or brittle.
- Reduces excess shedding – Some users report less hair fall after consistent use.
Everyone’s hair reacts differently, but if you're looking for something natural that supports growth and scalp health, MSM might be worth a try.
How to use MSM powder for curly hair
- As a supplement – Mix the powder into water or juice, or take it in capsule form if you don't like the taste.
- In DIY treatments – Add MSM to your deep conditioners, hair masks, or scalp oils for topical use.
- In leave-ins – Blend a small amount into your favourite curl cream or leave-in conditioner.
Start with a low dose and increase gradually. Some people experience detox symptoms like mild headaches when they first start taking it, this usually passes as your body adjusts.
What to expect when using MSM powder
MSM isn’t a miracle overnight fix. You’ll likely need to use it consistently for several weeks (or months) to see results. Here’s what people often report:
- A healthier, more balanced scalp
- Stronger, more elastic strands
- Improved length retention due to reduced breakage
- Subtle curl definition improvement over time
Taking photos or keeping notes can help you track your progress, since changes are often gradual.
Best ingredients to pair with MSM powder
- MSM + aloe vera – Great for soothing the scalp and promoting hydration when used topically.
- MSM + biotin – A popular combo for supporting healthy hair from the inside out.
- MSM + vitamin C – Helps your body absorb MSM better. Try taking your powder with orange juice.
Can MSM powder cause side effects?
For most people, MSM is safe when used in moderation. But like any supplement, it can cause side effects for some:
- Headaches or mild digestive upset during the first few days
- Fatigue or breakouts due to detox effects
- Faster nail and hair growth (bonus?)
Start with a low dose (e.g. 1/8 tsp daily), drink plenty of water, and give your body time to adjust. If you're unsure, check with a healthcare professional first.
How to choose a high-quality MSM powder
- Look for purity – Products labelled as “OptiMSM” are considered high quality and third-party tested.
- Watch for fillers – Avoid powders with added sugars, colours, or unnecessary extras.
- Pick your format – Powder mixes easily with drinks, but capsules are great if you prefer convenience.
What to know before getting started
- Start slow – Begin with a small dose and work your way up.
- Be consistent – MSM works best when used daily over time.
- Stay hydrated – Water helps reduce detox effects and supports your scalp.
- Check for interactions – If you're on medication or have a health condition, talk to a doctor first.
Final thoughts on MSM powder for curly hair
MSM powder isn’t a magic fix - but early research and anecdotal evidence suggest it may support hair growth, scalp health, and stronger strands over time.
From stronger strands to a happier scalp, this natural supplement has earned its place in the routines of many with curly hair. Whether you take it internally or add it to your deep conditioner, MSM could be the low-key hero your routine’s been missing.
