More clinical studies than any laser hair growth device.

HairMax has invested in clinical studies on light energy for hair growth across HairMax laser devices. These studies included 460 men and women and were conducted at leading medical research centres including the Cleveland Clinic, the University of Miami, and the University of Minnesota.

  • Multi-centre, double-blind, randomised controlled device study designs.
  • Designed to support 510(k) submissions to the FDA.
  • Approved by an IRB and run to Good Clinical Practice guidelines.
  • Monitored by a contract research organisation.

How laser therapy helps

Designed to support follicles through the growth cycle.

Low-level laser therapy uses therapeutic red light to help energise hair follicles and support thicker, healthier-looking hair over time. The result is a non-invasive routine that fits at home, without asking customers to start with medication.

1
Light reaches the scalpMedical-grade laser diodes deliver targeted red light directly to thinning areas.
2
Follicles receive energyThe treatment is designed to support cellular activity around the hair follicle.
3
Consistency builds resultsHairMax devices are made for regular home use, helping customers stay with the routine.
Clinical study design

Measured at baseline, 16 weeks, and 26 weeks.

Subjects were instructed to use the laser device three times per week on non-consecutive days. Hair density measurements were taken throughout the study period to assess terminal hair count changes from baseline.

Clinical photography

Global and macro images from HairMax study materials.

Qualified subjects had global images recorded at each visit using a stereotactic device, with target areas prepared for hair density evaluation and blinded review.
