research 1618 Simulated solar radiation (SSR) induced skin inflammation across skin types measured by dynamic optical coherence tomography and laser doppler
Sunlight simulation causes skin inflammation, with different skin types reacting at different levels of exposure.
research Photobiomodulation devices for hair regrowth and wound healing: a therapy full of promise but a literature full of confusion
Photobiomodulation may help with hair growth and wound healing, but research is inconsistent and needs better quality studies.
research The effects of narrowbands of visible light upon some skin disorders: a review
Visible light can improve skin disorders and hair loss, but more research is needed to understand long-term effects.
research Estimation methods for human circadian phase by use of peripheral tissues
New method uses hair follicle cells to estimate human body clock phase, potentially improving sleep disorder diagnosis.
research Extended theory of selective photothermolysis: A new recipe for hair cooking?
Permanent hair removal is hard, but using longer laser pulses at lower power might improve results.
research INTERACTION OF α-MELANOCYTE-STIMULATING HORMONE, MELATONIN, CYCLIC AMP AND CYCLIC GMP IN THE CONTROL OF MELANOGENESIS IN HAIR FOLLICLE MELANOCYTES IN VITRO
α-MSH and cyclic AMP boost melanin production, while cyclic GMP and melatonin reduce it.
research Induction of ornithine decarboxylase in specific subpopulations of murine epidermal cells following multiple exposures to 12-O-tetradecanoylphorbol-13-acetate, mezerein and ethyl phenylpropriolate
TPA strongly increases ODC activity in certain skin cells, potentially aiding tumor growth.
research Chronic circadian misalignment is a risk factor for hair growth impairment
Disrupted sleep patterns from artificial light can slow hair growth and may lead to hair loss.
