TRIOXIDIL® is FOLIGAIN’s hair care complex for thinning hair. This timeline follows what happened in a four-month clinical study of the TRIOXIDIL® regimen, so you know what to look for at each stage and when to judge your results.
About the study
- Who: 61 adults (30 men and 31 women), ages 18 to 75, with self-assessed thinning hair that felt dry, weak or thin. People with a diagnosed hair loss condition did not take part.
- What they used: TRIOXIDIL® Shampoo and Conditioner three to five times a week, and TRIOXIDIL® Topical Treatment once a day.
- How long: four months of use (January to May 2019), with assessments at the start, at month 2 and at month 4.
- How it was measured: clinical expert assessment, macro photography of a fixed scalp area, a controlled brush-friction count and a participant questionnaire.
- Who ran it: Princeton Consumer Research Corp, 2019.
The timeline at a glance
| When | What the study found | What to do |
|---|---|---|
| Day 1 | Starting point: evaluators scored volume at 1.5 out of 5 and shine at 1.8 out of 5. | Take starting photos and set a routine you can keep. |
| Month 2 | 44% fewer broken hairs when brushing. Softness rose from 2.5 to 4.0 out of 5. 98% of participants said their hair looked fuller. | Keep going and compare photos with day 1. |
| Month 4 | 76% fewer broken hairs when brushing. Volume rose from 1.5 to 4.3 out of 5. More visible hairs counted in the measured scalp area. | The fairest point to judge your results. |
| After month 4 | The study ended at four months. | Keep using your routine to keep your hair looking its best. |
Day 1: your starting point
At the start of the study, a clinical evaluator scored each participant’s hair on a 0–5 scale. Volume averaged 1.5, shine 1.8, thickness 2.5, softness 2.5, scalp appearance 2.3 and strength 3.0. Visible hairs in a fixed scalp area were counted with macro photography, averaging 126.4.
This is the moment to take your own starting photos: same room, same light, same angle, hair dry and styled the same way.
Month 2: less breakage, softer hair
The first changes participants noticed were in how their hair felt and how much broke during brushing.
- 44% fewer broken hairs and 33% fewer intact shed hairs were collected during a controlled brushing test.
- Evaluator scores rose for shine (1.8 to 3.0), volume (1.5 to 2.9), softness (2.5 to 4.0) and scalp appearance (2.3 to 3.6).
- 98% of participants agreed their hair looked fuller and thicker, and 95% said it felt softer.
- 75% said they could see more hairs, and 80% said they were losing fewer hairs.
The visible hair count in the measured scalp area had not changed yet at month 2. That comes later, so this is not the time to stop.
Month 4: the clearest results
By the end of the study, every evaluator score had improved, and the count of visible hairs had gone up.
- 76% fewer broken hairs and 82% fewer intact shed hairs collected during brushing.
- Evaluator scores reached 4.3 for volume, 3.4 for thickness, 4.7 for softness, 4.0 for shine, 4.5 for scalp appearance and 3.8 for strength, out of 5.
- Visible hairs in the measured scalp area rose from 126.4 to 132.6, a statistically significant increase.
- 100% of participants agreed their hair looked fuller, 89% said they were losing fewer hairs and 85% said they could see more hairs.
Shine, volume, thickness, softness and scalp appearance showed statistically significant gains at each monthly assessment.

Getting the most from your routine
- Use the full regimen: shampoo and conditioner three to five times a week, and the topical treatment once a day.
- Apply the topical treatment to the scalp, not just the hair.
- Take photos monthly, not daily. Compare day 1 with months 2 and 4.
- Choose a supply size you will keep up with. A larger supply lowers the price per month.
- Many people pair TRIOXIDIL® with FOLIGAIN minoxidil. Follow the directions on each product.

Do I need to use all three products?
The study tested the full regimen: shampoo, conditioner and topical treatment used together. That is the routine these results apply to.
Can I use TRIOXIDIL® with minoxidil?
Yes, many people use both. Follow the directions on each product, and ask a doctor or pharmacist if you have questions.
