research Improvement of Hair Growth in Mouse Skin by Application of Consciousness Energy Treated Test Item
The Biofield Energy Treated herbal mixture increased hair growth in mice compared to the untreated mixture.
research Hair-Hair Contact Dynamics and Interactions Studied with Atomic Force Microscopy
Hair movement can indicate hair quality and health.
research Effect of retinoids on follicular cells
Retinoids can change the hair growth cycle by extending the growth phase and shortening the rest phase.
research Telogen Effluvium
Telogen Effluvium causes more hair loss because hair moves to the resting phase too soon.
research The kinetics of moisture sorption by hair
Hair absorbs moisture differently based on its structure and treatment, with changes occurring at 30% humidity.
research Sensitive Quantitative In Vivo Assay for Evaluating the Effects of Biomolecules on Hair Growth and Coloring Using Direct Microinjections into Mouse Whisker Follicles
The new "whisker follicle microinjection assay" can test how different biomolecules affect hair growth and color.
research The effect of relative humidity on the spreading of ethanol on human hair fibers
Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.
research A Hair Growth-Promoting Effect of Chinese Black Tea Extract in Mice
Chinese black tea extract helped mice grow hair, especially when combined with capsaicin.
research Follicular Penetration of Caffeine from Topically Applied Nanoemulsion Formulations Containing Penetration Enhancers: In vitro Human Skin Studies
Nanoemulsion creams with certain enhancers can greatly increase caffeine delivery through skin.
