Clinical study ยท Skin and Cancer Foundation Inc. ยท 2026
17.4% more hair on average in 6 months.
We tested the actual products, not just their ingredients. We gave the HairSmart Protocol to 30 men and women with pattern hair loss, and dermatologists measured every scalp for 6 months.
Individual results vary.

Quality of life
Hair loss bothered them half as much
After 6 months, participants said hair loss affected their confidence, social life and daily routine far less.

Measured with the Dermatology Life Quality Index (DLQI), a standard 10-question survey on how a scalp or skin condition affects daily life. Average scores fell from 9.2 to 4.4 (lower is better).

Questions about the study
No. Most brands rely on published research on individual ingredients. We tested our actual products, on real people with pattern hair loss, measured by dermatologists.
It was an open-label, single-group, before-and-after study. 30 adults (16 women, 14 men, ages 29โ74) took the protocol daily for 6 months, with visits at baseline, 3 and 6 months. Hair count and terminal-to-vellus ratio were measured by TrichoScan in the same marked scalp zones at every visit, with no needles or biopsies.
It means a change is unlikely to be down to chance alone. We used a Wilcoxon signed-rank test (two-sided, ฮฑ=0.05). The hair count gains were significant at p<.001 for all participants, for women and for men.
TVR is the terminal-to-vellus hair ratio: how many thick, mature (terminal) hairs there are compared with fine, short (vellus) ones. A higher ratio means more mature hair. We report the average of each participant's percentage change from baseline to 6 months.
The study tested the full HairSmart protocol: the Protect DHT Blocker and H5 Growth+ Vitamin taken together daily, plus the Growth Accelerator Serum. The results reflect that combination. The DHT Blocker targets the hormonal root cause, the H5 Growth+ Vitamin provides the nutritional support follicles need to function, and the serum delivers actives directly to the scalp.
We also offer products individually for customers who want to build their routine gradually. If youโre not sure where to start, the hair quiz matches you to a protocol based on your hair loss type and goals.
The study measured results at 3 and 6 months, and the data show that improvement continued between those two time points. Hair growth is a slow biological process. The hair cycle takes months. Most participants in the study started noticing changes between months 2 and 4, with the clearest visible results appearing closer to months 5 and 6.
With any supplement routine, consistency matters. If you stop after 6 months, the underlying cause of your hair loss (DHT, nutrient deficiency, inflammation) doesnโt stop. Most people who see results continue using the protocol to maintain them.
No. Zero side effects were reported across all 30 participants over 6 months.
No scalp irritation. No allergic reactions. No medication interactions. Every participant was examined by a doctor at baseline, 3 months, and 6 months. The clean safety record was physician-monitored throughout.
