Hair measurably thicker in 24 weeks.

thicker strands, not more of them

context

Could regular scalp massage make hair thicker over time? A small early study offers the first hint.

method

9 healthy men used a scalp-massage device for four minutes a day, on just one side of the head, for 24 weeks.

finding

Over 24 weeks, hair shafts grew roughly 8% thicker (0.085 mm to 0.092 mm), though the number of hairs stayed the same.

What this study shows

Hair-shaft thickness rose from 0.085 mm to 0.092 mm (about 8%) with daily device massage
A measurable change in a surrogate marker over 24 weeks
A reasonable prompt for larger, better-controlled research

What this study does not show

Just nine men, no blinding, and part-funded by the device maker
The number of hairs didn't change
Thicker shafts are not the same as new growth or fuller hair

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.
