Scalp Massagers for Thinning Hair: What Two Small Studies Found

Scalp massagers range from a few-dollar silicone shower brush to rechargeable vibrating devices. They feel good, and social media credits them with thicker hair. Here is what the research behind that claim tested, so you can decide how much to expect and how much to spend.

Study 1: nine men and a massage device

In a 2016 study, nine healthy Japanese men used a scalp massage device for 4 minutes a day for 24 weeks. Their hair strands got slightly thicker on average, from 0.085 to 0.092 millimeters. The researchers also stretched hair follicle cells in a lab dish and saw changes in genes linked to the hair cycle.¹

There was no comparison group, no women, and no measured change in the number of hairs reported in the summary.¹ It’s an early clue, not proof.

Study 2: a self-reported survey

In a 2019 survey study, 1,899 people with pattern hair loss were shown how to do a hands-only scalp massage for 20 minutes twice a day. Of those, 340 answered a later survey about whether their hair seemed to change.² Results were based on people’s own impressions, collected after the fact, from the minority who responded.² That design can’t separate the massage from other treatments people were using, or from the hope of seeing a change.

What that means for your money

The evidence is thin. If you enjoy a scalp massage and keep it gentle, an inexpensive soft silicone brush is a modest treat. There’s no research basis for paying extra for vibration, heat or red-light add-ons on a massager on the strength of these two studies.

Be gentle: press and move the scalp rather than scrubbing the hair, and stop if your scalp gets sore, red or flaky.

Treatments with stronger evidence

The American Academy of Dermatology³ says effective treatment starts with finding the cause, and a dermatologist may order a blood test or scalp biopsy.³ For female pattern hair loss, products with 2% or 5% minoxidil are approved, and the AAD says it takes six to 12 months of continuous use to judge results.⁴ If a massage habit helps you remember to apply a treatment, that’s a fine pairing. Ask your dermatologist whether to massage before or after applying it.

Try: “My part has been widening for a year. What kind of hair loss is this, and what treatment would you suggest? Is a scalp massager worth adding?”
