Shilajit for Skin and Hair: What the Studies Show

Shilajit (salajeet) has two small studies relevant to skin: in healthy women, 250 mg twice a day for 14 weeks improved blood flow in the skin, and in trained men it raised a blood marker of collagen production. Neither measured wrinkles or glow. For hair growth or hair fall, there is no study at all.

Glowing skin and stronger hair are popular claims for Shilajit (salajeet), especially on social media. A few studies have looked at skin; none has looked at hair. This article separates the two.

Skin: what the trials found

Blood flow in the skin

In a 14-week trial, healthy women took 250 mg of Shilajit twice a day or a placebo (Das et al., 2019). In the Shilajit group:

• blood flow in the skin improved;
• genes involved in forming small blood vessels were switched on;
• no side effects were reported.

Better blood supply could, in theory, help skin health, but the study did not measure wrinkles, glow or how the skin looked.

Collagen

Collagen is the protein that keeps skin firm. In 35 trained men, 500 mg and 1,000 mg of Shilajit a day for 8 weeks raised a blood marker of collagen production, while placebo did not (Neltner et al., 2024). An earlier study in overweight adults found that genes for muscle repair and tissue elasticity were switched on (Das et al., 2016). These were not skin studies, but they point the same way.

Hair: no evidence yet

We could not find any study of Shilajit for hair growth, hair fall or grey hair. Claims that it “stops hair fall” are not backed by research. Hair loss often has a treatable cause, such as low iron (see Shilajit and anemia), thyroid problems, stress or genetics, so it is worth seeing a doctor or dermatologist.

Anti-ageing claims

Fulvic acid is often sold as “the strongest natural antioxidant”. Lab studies do describe antioxidant activity, but reviews judge that such effects have not been proven in people (Wilson et al., 2011), and no study has shown that Shilajit slows visible skin ageing. Stories about long-lived elders in Hunza are often repeated, but they are not evidence for any single food or supplement.

If your hair is falling

• Ask your doctor to check iron (ferritin), thyroid and vitamin D; these are common, treatable causes.
• Eat enough protein: daal, eggs, milk, meat or chicken.
• Sudden, patchy or heavy hair loss needs a dermatologist.

By mouth, not on the skin

Every study above gave Shilajit by mouth. Face masks and hair packs made with resin have not been studied, and the resin can irritate sensitive skin. If you want to try it on your skin, test a small patch on your arm first.

How to take it

• The skin trial used 250 mg twice a day, which is within the usual 300 to 500 mg daily range. See how to take Shilajit.
• Allow time: the skin trial ran for 14 weeks.
• Use purified resin with a published lab report: how to identify real Shilajit.

The bottom line

For skin, there are two small, encouraging studies on blood flow and collagen. For hair, there is no evidence at all. Shilajit may support skin from the inside, but it is not a beauty treatment with proven visible results.
