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...
Background Caffeine reportedly counteracts the suppression of hair shaft production by testosterone in organ-cultured male human hair follicles (HFs). Objectives We aimed at investigating the impact of caffeine a) on additional key hair growth parameters, b) on major hair growth-regulatory growth factors and c) on male versus female HFs in the presence of testosterone. This article is protected...
Ferrous ferric chloride (FFC) is a distinct form of aqueous iron composed of a complex of ferrous chloride and ferric chloride that participates in both oxidation and reduction reactions. The author's previous study showed that the supplementation of culture medium with FFC stimulated the proliferation and differentiation of keratinocytes and melanocytes in newborn mice. FFC also stimulated the...
Peppermint (Mentha piperita) is a plant native to Europe and has been widely used as a carminative and gastric stimulant worldwide. This plant also has been used in cosmetic formulations as a fragrance component and skin conditioning agent. This study investigated the effect of peppermint oil on hair growth in C57BL/6 mice. The animals were randomized into 4 groups based on different topical ap...
Mechanisms that regulate the growth of eyelashes have remained obscure. We ascertained two families from Pakistan who presented with familial trichomegaly, or extreme eyelash growth. Using a combination of whole exome sequencing and homozygosity mapping, we identified distinct pathogenic mutations within fibroblast growth factor 5 (FGF5) that underlie the disorder. Subsequent sequencing of this...
BACKGROUND Biotin has gained commercial popularity for its claimed benefits on healthy hair and nail growth. Despite its reputation, there is limited research to support the utility of biotin in healthy individuals. OBJECTIVE To systematically review the literature on biotin efficacy in hair and nail growth. METHODS We conducted a PubMed search of all case reports and randomized clinical tr...
OBJECTIVE Dermal papilla and hair epithelial stem cells regulate hair formation and the growth cycle. Damage to or loss of these cells can cause hair loss. Although several studies claim to reconstitute hairs using rodent cells in an animal model, additional research is needed to develop a stable human hair follicle reconstitution protocol. In this study, we have evaluated hair induction by inj...
It is generally agreed that the dermal papilla is a vital component of the hair and feather follicle. Lillie & Wang (1941, 1944) and Wang (1943) have shown for feather follicles that if the dermal papilla, which normally maintains its integrity throughout the growth cycles, and its ectodermal investment are removed from the follicle, feather production ceases. However, if a dermal papilla is tr...
Hair Paint is a modeling and animating tool for hair and furry objects. In this paper some improvements are done to Hair Paint to add some new features like adding hair gel to modify the physical behavior of hair or fur, addition of pony tails and hair growth direction to make more complex hair styles. We also implemented mechanisms that avoid the hairstyle mess up due to wind forces.
