research Efficacy of intramuscular injections of biotin and dexpanthenol in the treatment of diffuse hair loss: A randomized, double‐blind controlled study comparing two brands
Both brands of biotin and dexpanthenol injections improved hair loss, with Bayer also increasing the ratio of thick to thin hairs.
research Steroids excreted by human skin. I. C19-steroids in axillary hair.
Human skin releases different steroids, with some coming from sebaceous glands and others from sweat glands.
research Cutaneous hydroxystereoid dehydrogenases and rat-hair-cycle
Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.
research Effects of glucocorticoid on human dermal papilla cells in vitro
Dexamethasone may cause hair loss by stopping cell growth.
research TrichoScan
TrichoScan accurately measures hair growth and loss, showing increased hair counts and thickness with treatment.
research Evaluation of a new X-ray fluorescent analysis technique for the creation of a Nordic hair database: elemental distributions within the root and the virgin segment of hair fibers.
The new X-ray technique allows for precise and non-destructive measurement of elements in hair, creating the first database of its kind for a specific ethnic group.
research Hair diameter diversity: a clinical sign reflecting the follicle miniaturization.

research A 29 Year Old Man with Patchy Hair Loss
The man has patchy hair loss likely due to alopecia areata.
research Determinants of hair cortisol and hair cortisone concentrations in adults
Hair cortisol and cortisone levels increase with age, are higher in diabetics, vary by gender, decrease with frequent hair washing, and are lower in winter.
research Supplementary Material for: Dexamethasone, a synthetic glucocorticoid, induces the activity of androgen receptor in human dermal papilla cells
Dexamethasone increases androgen receptor activity in scalp cells, which might explain stress-related hair loss.
research LC‐MS/MS‐based method for long‐term steroid profiling in human scalp hair
A new method accurately measures long-term steroid levels in human hair.
research Reliability and Validity of a Photographic Method for Measuring Facial Hair Density in Men
The photographic method for measuring facial hair density is reliable and valid but needs further testing on different hair densities and skin colors.
research Dexpanthenol may be a novel treatment for male androgenetic alopecia: Analysis of nine cases
Dexpanthenol improves hair growth in male baldness.
research SERUM-CONCENTRATIONS OF Dehydroepyandrosterone-sulfate IN MEN WITH ANDROGENETIC ALOPECIA
Men with hair loss don't necessarily have higher levels of the hormone DHEA-S, but this hormone tends to decrease with age.
research Helpful diagnostic markers of steroidogenesis for defining hyperandrogenemia in hirsute women
The study concluded that androstendione and DHEA are important for diagnosing high male hormone levels in women with excessive hair growth.
research Direct quantitative digital autoradiography of testosterone metabolites in the pilosebaceous unit: an environmentally advantageous trace radioactive technology
