research Growth and viability of Liaoning Cashmere goat hair follicles during the annual hair follicle cycle
This study observed that primary hair follicles in Liaoning Cashmere goats had broader hair bulb widths compared to secondary follicles, with the difference diminishing during the anagen phase of hair follicle development.
research Hair Growth Promoting Effect of 4HGF Encapsulated with PGA Nanoparticles (PGA-4HGF) by β-Catenin Activation and Its Related Cell Cycle Molecules
This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.
research Scanning Electron Microscopic Study on Collagen Fibrils in the Mink Dermis during the Hair Cycle and Growth
This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.
research Integrative and Mechanistic Approach to the Hair Growth Cycle and Hair Loss
This review evaluates the hair cycle's phases and the factors influencing the transition between anagen and telogen, advocating for a holistic approach to addressing hair loss, though no specific results are reported.
research GROWTH FACTORS IN HAIR ORGAN DEVELOPMENT AND THE HAIR GROWTH CYCLE
This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.
research Shikimic acid, a mannose bioisostere, promotes hair growth with the induction of anagen hair cycle
In this study using a mouse model and human hair follicle cells, shikimic acid was found to promote hair growth and may serve as a new therapeutic agent for alopecia.
research The genetically programmed hair growth cycle and alopecia: what is there to know?
This review discusses recent advances in hair follicle research, highlighting therapeutic and cosmetic applications, but reports no new study results.
research The effects of finasteride (Proscar) on hair growth, hair cycle stage, and serum testosterone and dihydrotestosterone in adult male and female stumptail macaques (Macaca arctoides).
Finasteride increases hair growth, prolongs hair cycle, and lowers dihydrotestosterone levels.
research Differential effects of caffeine on hair shaft elongation, matrix and outer root sheath keratinocyte proliferation, and transforming growth factor‐β2/insulin‐like growth factor‐1‐mediated regulation of the hair cycle in male and female human hair folliclesin vitro
