Trichogram photographs (from the double blind versus placebo clinical trial, grade 3 to 4 alopecia volunteers) display the results after only three months. The subject on the far-left (52 year old tester) had 28,200 new hairs (+ 47 hairs per cm2). Of course, at three months they are not "full-length" hairs, but obviously enough to show a visible, discernible difference, and as you can see the growth is evident on both the hairline and crown. A reminder that the average person has at least 100,000 or more hairs on the scalp, so it makes sense that this tester visibly shows a 28% increase in density in the photograph.
The 28,000 number is a maximum experienced by the testers in the study; the average was less. Perhaps the most striking effect was that hair fall decreased 17%, and we have many customers who have commented (and posted reviews) that they experienced real results within just a week or two of starting RevivHair Stimulating Serum, primarily by it noticeably/abruptly stopping existing shedding. While everyone is of course "bio-individual" you may very well find that you can expect this effect in just a few weeks of use.
The efficiency of Redensyl® at 3% was evaluated in the double-blind test versus a placebo. Twenty six male volunteers were selected by following specific inclusion criteria: between 18 to 70 years old, brown to dark hair, with a minimum density of hair of 150 hair/cm2 and 40 telogen hair/cm2, with clinically confirmed grade 3 to 4 alopecia. Volunteers applied the placebo or the product with 3% of Redensyl® on their whole scalp daily for 3 months.
A shaved area of 1.5cm2 was defined on each volunteer to allow the measurements on a window of 0.7cm2 at D0, D28 and D84. Phototrichograms were realized using a NIKON camera associated with Canfield® Epiflash System and a contact plate to press hair on the scalp. Analysis were run with Photoshop CS5 extended® and permitted to define if hair were in anagen, telogen or undetermined phase.
Results: A non significant placebo effect is observed (mechanical activation of micro-circulation), with almost no more evolution after 1 month. Redensyl® increases the percentage of hair in anagen phase by 9% compared to T0 after 3 months, and decreases the percentage of hair in the telogen phase by 17% compared to T0 after 3 months.
