Purpose: To investigate the effect of Glycyrrhiza glabra root extract on hair growth in female Wistar rats. Methods: Female Wistar rats were used for the hair growth promotion studies. They were divided into three groups(n = 6) and their dorsal skin was completely denuded to completely remove hair. Paraffin oil (control), 2 % minoxidil solution (reference) or petroleum ether (60 – 80 C) root ex...

Seedlings of Arabidopsis thaliana, Columbia ecotype, were used in vitro to analyze root hair growth response to inoculation by the plant-growth-promoting rhizobacterium, Azospirillum brasilense Sp-245. Root hair length was measured at physiologically-identical stages of root growth. In seedlings inoculated with A. brasilense, root hairs were more than twice the length of those of the non-inocul...

objective: objective: dermal papilla and hair epithelial stem cells regulate hair formation and growth cycle. damage to or losing of these cells can cause hair loss. although several studies have claimed to reconstitute hairs using rodent cells in animal model, a stable human hair follicle reconstitution protocol needs more studies. here in this study we evaluated hair induction through injecti...

Biota orientalis L. leaf extract (BOLE) is used medically to improve strength and arrest hemorrhage. In China, BOLE has been used in traditional medicine for its antibacterial properties and for hair restoration. In this study, we investigated the mechanism of hair restoration by BOLE from the point of view of the sebum suppressant effect and hair loss prevention. BOLE at 25 or 50 μg/mL final c...

Eclipta alba (L.) Hassk, Asiasarum sieboldii (Miq.) F. Maek (Asiasari radix), and Panax ginseng C. A. Mey (red ginseng) are traditionally acclaimed for therapeutic properties of various human ailments. Synergistic effect of each standardized plant extract was investigated for hair growth potential on nude mice, as these mutant mice genetically lack hair due to abnormal keratinization. Dried pla...

BACKGROUND Algae have traditionally been used for promotion of hair growth. Use of hair regrowth drugs, such as minoxidil, is limited due to side effects. The aim of this study was to examine a mixture of Saccharina japonica and Undaria pinnatifida (L-U mixture) on hair growth and to compare the promoting effect of hair growth by a 3% minoxidil and a L-U mixture. METHODS To evaluate the hair ...
