Where the evidence stands
One small 2015 trial found rosemary oil and 2% minoxidil gave similar hair counts after six months in men with pattern hair loss. It has not been convincingly repeated, and 2% is the weaker strength of minoxidil.
How it's used: A few drops diluted in a carrier oil, massaged into the scalp.
A small 2014 trial in 76 men found modestly higher hair counts after 24 weeks of capsules compared with placebo. The capsules also contained other ingredients.
How it's used: Oral capsules; sometimes as a topical oil.
A small 2024 trial in 60 women with pattern thinning found amla syrup taken for 12 weeks improved the share of hairs in the growing phase compared with placebo. One trial, short follow-up.
How it's used: Eaten as fruit or syrup, in oils, or as powder in hair packs.
Studies in mice show faster hair regrowth with Eclipta extracts. There are no good-quality human trials yet.
How it's used: Infused oils, applied before washing.
A tiny 2002 study in patchy hair loss (alopecia areata) reported regrowth in some people. It has not been tested for everyday hair fall or pattern hair loss.
How it's used: Applied to the scalp, then washed off.
May reduce stress in some trials, and stress can trigger shedding. There is no direct evidence that it grows hair.
How it's used: Capsules or powder taken by mouth.
A US study found lead, mercury or arsenic in about 1 in 5 Ayurvedic medicines bought online, both US- and Indian-made (Saper 2008, JAMA ↗). Buy from makers that publish lab testing, patch-test oils on your skin first, and tell your doctor what you take, especially if you are pregnant or on other medicines.

If you want something with stronger evidence
For pattern thinning, minoxidil (and finasteride for men) are far better studied than any herbal option. You can use a herbal oil alongside them. Minoxidil vs natural alternatives →
