| Popis: | Hair loss is a common aesthetic disorder that can be triggered by genetic, inflammatory, hormonal, and environmental factors acting on hair follicles and their life cycle. There are several types of hair loss that differ in causes, symptoms, and spatial and temporal progression. Androgenic alopecia, a common form of hair loss, is the consequence of a decreased microcirculation of the scalp as well as the toxic action of elevated dihydrotestosterone levels on the hair bulbs. In the present study, the lotions TRINOV Lozione Anticaduta Uomo and TRINOV Lozione Anticaduta Donna, containing dihomo-γ-linolenic acid (DGLA), S-equol, and propionyl-l-carnitine, were tested on 30 men and 30 women (mean age of men was 46.6 ± 6.4 years; mean age of women was 49.5 ± 9.0) with signs of androgenic alopecia, respectively. DGLA is a precursor of the prostaglandin PGE1, which acts by improving microcirculation; S-equol inhibits 5α-reductases, thus preventing the transformation of testosterone into dihydrotestosterone; and propionyl-l-carnitine promotes lipid metabolism, stimulating energy production. These three molecules are loaded into liposomes for their effective transdermal delivery. Daily topical applications of the lotions resulted in a hair count that significantly increased for women and marginally increased for men after 6 months of treatment. Furthermore, significant increase in anagen hair and a significant decrease in telogen hair were observed starting from 3 months in male and 1 month in female patients. Thus, the formulations under investigation were effective in attenuating androgenic alopecia-related hair loss in men and women. |
