The study's conclusions
Across four months, evaluators saw steady improvements in shine, volume, thickness, softness and scalp appearance, with significant gains at each monthly assessment. Hair strength improved, macro photos showed more visible hairs in a fixed area, and brushing tests showed less loss related to breakage.
The researchers concluded that the TRIOXIDIL® regimen provided strong cosmetic support for men and women concerned about thinning hair and early signs of hair loss.
What participants said
At month four, self-perception questionnaires were highly favorable: a majority of participants reported improvements in the look of hair thickness, volume, scalp health and reduced visible hair loss from breakage.
Putting it into practice
If you'd like to follow the routine that was studied:
- Wash with TRIOXIDIL® Shampoo and Conditioner three to five times a week.
- Apply the TRIOXIDIL® Topical Treatment once a day.
- Give it at least two to four months before judging results.
- Take monthly photos in the same light to track changes.
- If you're actively losing hair, consider adding OTC Minoxidil and talk to a dermatologist.
