ESR2 gene variations may be linked to female pattern hair loss.
research Expression of type I hair keratins in follicular tumours
Pilomatrixomas likely originate from the hair matrix due to changes in hair keratin expression.
research Effect of cyproterone acetate on rate of hair growth in hirsute females
Cyproterone acetate reduced hair growth in most hirsute females and made hair softer, thinner, and lighter.
research Hypoxia improves hair inductivity of dermal papilla cells via nuclearNADPH oxidase 4‐mediated reactive oxygen species generation'
Low oxygen levels can make hair-growing cells better at growing hair through a process involving reactive oxygen species.
research Differential expression and functionality of ATP-binding cassette transporters in the human hair follicle
Certain transporters are found in human hair follicles and may affect hair growth and loss.
research How effective is intralesional injection of triamcinolone acetonide compared with topical treatments in inducing and maintaining hair growth in patients with alopecia areata? A Critically Appraised Topic
Intralesional triamcinolone acetonide can regrow hair in alopecia areata but often has temporary effects and side effects.
