research Changes in serum free testosterone, sleep patterns, and 5‐alpha‐reductase type I activity influence changes in sebum excretion in female subjects
Sleep, testosterone levels, and a specific enzyme activity affect skin oil production in women.
research MELATONIN
Melatonin may help with sleep issues, depression, and cancer, but more research is needed.
research Effects of maintaining solstice light and temperature on reproductive activity, coat growth, plasma prolactin and melatonin in goats
Goat reproductive activity and coat growth are affected by light and temperature, with temperature altering prolactin levels and hair growth, but not melatonin or estrus onset.
research Aging in hair follicle stem cells and niche microenvironment
Aging in hair follicle stem cells leads to hair graying, thinning, and loss.
research ORIGINAL RESEARCH—ENDOCRINOLOGY: Comparison of the Steady‐State Pharmacokinetics, Metabolism, and Variability of a Transdermal Testosterone Patch Versus a Transdermal Testosterone Gel in Hypogonadal Men
The testosterone patch and gel are both effective, but they have different absorption patterns and effects on hormone levels.
research Human long-term deregulated circadian rhythm alters regenerative properties of skin and hair precursor cells
Disrupted sleep patterns can harm skin and hair cell renewal, but melatonin might help.
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.
research Hair test reveals plasticity of human chronotype
HairTime can predict and adjust human sleep patterns using a hair sample.
research Large Scale Gene Expression Profiles of Regenerating Inner Ear Sensory Epithelia
Birds can regenerate inner ear cells using specific gene pathways, unlike mammals.
research The transcriptional landscape of seasonal coat colour moult in the snowshoe hare
Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.
research Measurement of hair growth
Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.
research Simultaneous LC-MS/MS quantification of glucocorticoids, melatonin and its metabolites in hair
The new method can measure sleep-related hormones in hair effectively and could help track long-term sleep patterns.
research Light Pollution and Oxidative Stress: Effects on Retina and Human Health
Excessive blue light harms eye cells and disrupts sleep patterns.
research Quantitation of Hepatitis C Virus RNA
Long-term high-dose fluconazole can cause reversible hair loss.
research Circadian clocks: from stem cells to tissue homeostasis and regeneration
Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.
research Investigation of a non-invasive method of assessing the equine circadian clock using hair follicle cells
RNA from horse hair follicles can track circadian rhythms non-invasively.
research Peripheral Skin Temperature and Circadian Biological Clock in Shift Nurses after a Day off
Shift nurses show altered body temperature and stress hormone levels, suggesting their body clocks adjust to irregular schedules.
research Mechanism of Sleep Disturbance in Children with Atopic Dermatitis and the Role of the Circadian Rhythm and Melatonin
Children with atopic dermatitis often have sleep problems due to itching and may benefit from melatonin, which helps with sleep and skin symptoms.
research Minoxidil and male-pattern alopecia: a potential role for a local regulator of sebum secretion with vasoconstrictive effects?
Minoxidil, a common hair loss treatment, might work by counteracting a hormone that reduces hair growth and promotes hair loss.
research The circadian molecular clock creates epidermal stem cell heterogeneity
The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.
research Noninvasive method for assessing the human circadian clock using hair follicle cells
Scientists found a new, less invasive way to study body clocks using hair cells, which shows shift workers' body clocks don't match their lifestyles.
research Circadian clock-mediated control of stem cell division and differentiation: beyond night and day
The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.
research Stem cells and the circadian clock
The circadian clock influences the behavior and regeneration of stem cells in the body.
research A simple method using ex vivo culture of hair follicle tissue to investigate intrinsic circadian characteristics in humans
Researchers developed a way to study human body clocks using hair tissue, which works similarly in both healthy and dementia patients.
research The Circadian Clock in Skin
The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.
research Nocturnal eczema: Review of sleep and circadian rhythms in children with atopic dermatitis and future research directions
Children with atopic dermatitis often have sleep problems, affecting their growth and behavior.
research Rhythmic expression of circadian clock genes in human leukocytes and beard hair follicle cells
Human leukocytes and beard hair follicle cells have internal daily clocks, and PER1 and PER3 genes may indicate individual circadian rhythms.
research Local circadian clock gates cell cycle progression of transient amplifying cells during regenerative hair cycling
Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
research Female pattern hair loss: A clinical, pathophysiologic, and therapeutic review
No cure for female pattern hair loss, but various effective treatments exist.
