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.
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.
