Hair Serum Clinical Study Results

In clinical and experimental studies using a 3% Procapil solution, 92% of users reported a reduction in hair loss, and a noticeable improvement in the quality of thinning hair was observed. While some manufacturers add very low levels of Procapil, it is important to note that significant hair loss treatment results should not be expected from such formulations. In hereditary hair loss observed in 95% of men, it has been shown that the concentration/effectiveness ratio of 3% is ideal. The success rate seen in clinical trials has been consistently observed in standard users as well. The use of 3% Procapil solutions differs from other hair regrowth products, as most require two doses daily, while Procapil is applied as a single daily dose after the first 3 months. The success achieved with this single daily dose of 3% Procapil continues to improve.

Peptide Biotinyl-GHK Clinical Research
In clinical studies on the active ingredient Peptide Biotinyl-GHK:

- The control group using the formula showed 121% more hair growth than those not using it.

- ß In vivo studies: A 4-month clinical study covering one full cycle of the telogen phase showed a significant increase in the anagen/telogen ratio in the group using the formula.

- After 14 days of use, strong lamination was observed in the papilla level of the hair follicle and in the outer root sheath. The protective and restorative effect of Peptide Biotinyl-GHK on hair follicles was observed to be 30 times higher.

- After 4 months of use, significant new formation was observed in the bulb region of the telogen hairs. The root sheath of the anagen hairs also thickened and transformed into clearly defined cell bases. High-quality root sheaths were observed, with excellent dermal-epidermal basal lamina adhesion on the outer side of the hair shaft. On the inner root sheath side, connection points with the hair shaft were observed.

Biotinyl-GHK, an effective peptide, ensured the retention of the hair thanks to adhesion proteins. Apigenin, with its vasodilator and flavonoid effect, inhibited the production of dihydrotestosterone (DHT) through the action of oleanolic acid derived from plant leaves, by blocking the 5a-reductase enzyme, which causes genetic hair loss.
A 4-month clinical study covering the telogen phase confirmed the noticeable anti-hair loss effect of the complex, testing its effectiveness. Morphological and immunohistochemical analyses of hair samples taken at the beginning and end of the study revealed significant changes in telogen hair bulbs, root sheaths, and the density of laminin 5 and collagen IV.
