- How does low level laser therapy actually stimulate hair growth? Low-level laser therapy is thought to work by boosting energy production in follicle cells. Sham-controlled trials report modest gains in hair counts, but the mechanism is not proven in people.
- Who benefits most from low level laser therapy—men, women, or both? Sham-controlled trials report hair-count gains in both men and women. The largest trial reported that the gain did not depend on sex, but no trial was designed to compare men with women.
- How many sessions of laser therapy are usually needed before noticing thicker hair? Controlled trials of home laser devices measured hair counts after 16 to 26 weeks of regular use. Average gains were modest and varied between people.
