Nearly three times as many saw improvement.

statistically significant: p = .008

context

Can hands-on scalp work matter for your hair itself, not just your mood? One careful trial says it can help.

method

86 people rubbed either an essential-oil blend or a plain carrier oil into their scalp every day for seven months, and neither they nor the assessors knew which was which.

finding

44% of the essential-oil group improved, versus 15% on plain carrier oil: a real, statistically significant difference (p=.008).

What this study shows

Daily scalp massage with certain essential oils beat a carrier-oil control (44% vs 15% improved, p=.008)
A real, statistically significant benefit for an autoimmune hair-loss condition
The trial was randomized and double-blind

What this study does not show

Alopecia areata is an autoimmune condition, different from the gradual thinning most people picture as “hair loss”
Both groups were massaged, so we can't credit the oils over the hands
It's a single trial that hasn't yet been repeated

Everybody's different, so results vary, and none of this is medical advice. If a scalp or hair concern sticks around, please see a doctor or dermatologist.
