Magnesium Hair Spray: Science, Benefits, and Best Practices
If you’ve heard people talking about using magnesium spray for hair, you’re not alone. From TikTok hacks to holistic wellness circles, this mineral-rich mist is gaining attention for its potential to support scalp and hair health. While there’s no solid clinical proof that magnesium spray promotes hair growth, science does suggest it may help create the right conditions for healthier hair and scalp.
Why Magnesium Matters for Hair
Magnesium is essential for hundreds of bodily processes—including protein synthesis, cell repair, and blood flow. Low magnesium levels have been linked to inflammation and poor circulation, both of which can impact scalp health. When used topically, magnesium chloride spray may help:
-
Support scalp circulation
-
Calm inflammation or itchiness
-
Balance oil production
-
Reduce buildup from calcium or styling products
While magnesium for hair growth hasn’t been proven in controlled studies, these effects can indirectly support stronger, shinier, more resilient hair.
How to Use Magnesium Spray for Hair and Scalp
-
Start with a clean scalp. Apply to dry or slightly damp hair before washing.
-
Spray directly on the scalp. Focus on roots or thinning areas.
-
Massage gently. Use fingertips to stimulate blood flow for 1–2 minutes.
-
Let it sit. Leave on for 10–20 minutes before rinsing or shampooing.
-
Adjust as needed. Use a few times per week, depending on tolerance.
Because magnesium chloride can feel slightly sticky, some users prefer to rinse it out, while others leave a light mist in as a scalp tonic.
Realistic Expectations
Using topical magnesium or magnesium hair spray won’t regrow hair overnight—but many people notice less scalp irritation, fewer flakes, and an overall “healthier” look and feel. Think of it as scalp nutrition: natural, minimal, and supportive of long-term balance.
What the Research Says
A PLOS One pilot study (Kass et al., 2017) found that topical magnesium cream led to measurable increases in magnesium levels in some participants, showing that magnesium can be absorbed through the skin. Gröber et al. (2017) reviewed the topic and concluded that topical magnesium may support localized effects like improved circulation and skin health, though more research is needed.
In 2024, Nightingale et al. demonstrated in Intestinal Failure that a topical magnesium formula helped raise magnesium levels in patients with absorption issues—further evidence that the skin can take in magnesium chloride.
The Bottom Line
Magnesium spray for hair is a simple way to care for your scalp naturally. While research is still catching up, anecdotal results and biological plausibility make it a worthy addition to your routine. When it comes to nurturing healthy hair from the root up, topical magnesium just might become your new secret weapon.
