research Finasteride increases anagen hair in men with androgenetic alopecia
Finasteride helps increase hair growth in men with hair loss.
research Diffuse female hair loss: are androgens necessary?
Female hair loss can occur without androgens.
research Hair follicle stem cell differentiation is inhibited through cross‐talk between Wnt/β‐catenin and androgen signalling in dermal papilla cells from patients with androgenetic alopecia

Hair analysis can track haloperidol dosage history.
research The hair cycle on the human thigh and upper arm
Men's thigh hair grows longer and has a longer growth cycle than women's, but arm hair growth is similar between genders.
research HAIR DIAMETER IN FEMALE BALDNESS
Women with thinning hair have thinner hair strands than women without hair loss.
research What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women
Caucasian women's hair appears thickest in their 20s, with perceived thinning after mid-30s due to both decreasing density and diameter.
research Differential effects of caffeine on hair shaft elongation, matrix and outer root sheath keratinocyte proliferation, and transforming growth factor‐β2/insulin‐like growth factor‐1‐mediated regulation of the hair cycle in male and female human hair folliclesin vitro
Caffeine affects hair growth and health differently in men and women.
research Rat hair follicle growth in vitro
Rat hair follicles grow longer in vitro, but certain factors can inhibit this growth.
research Trichothiodystrophy: an ultrastructural study of the hair follicle
Trichothiodystrophy causes abnormal protein deposits and distortion in hair follicles.
research Hair removal in hirsute women with normal testosterone levels: a randomized controlled trial of long-pulsed diode laser vs. intense pulsed light
Both intense pulsed light and long-pulsed diode laser effectively reduced facial hair in women, with no significant difference in satisfaction after 6 months, but intense pulsed light was more painful.
research ‘A detective look’ at hair biopsies from African-American patients
Recognizing specific features of African-American hair can help diagnose hair loss conditions.
research Low sex-hormone binding globulin levels in young women with diffuse hair loss
Young women with diffuse hair loss may have low SHBG levels, which could lead to more active testosterone and contribute to their hair loss.
research HAIR LOSS IN WOMEN
Hair loss in women often doesn't follow a pattern, isn't linked to age, may be genetic, and can be related to thyroid issues or other health factors.
research Hormonal changes in menopause: do they contribute to a ‘midlife hair crisis’ in women?
Menopause-related hormonal changes affect hair but are not the only cause of hair changes in middle-aged women.
research Procyanidin B-2, extracted from apples, promotes hair growth: a laboratory study
Apple extract called procyanidin B-2 was found to greatly increase hair growth.
research Hair greying is associated with active hair growth
White hair grows thicker and faster than black hair due to higher activity of growth-related genes and proteins.
research Prolonged maintenance of human hair follicles in vitro in a serum-free medium
Human hair follicles can grow in a lab for at least 9 days without serum, keeping their natural characteristics.
research Biology of the eyelash hair follicle: an enigma in plain sight
Scientists don't fully understand eyelash hair follicle biology, including growth and color, and suggest more research is needed.
research Absence of vellus hair in the hairline: a videodermatoscopic feature of frontal fibrosing alopecia
Lack of small, fine hair on the front hairline is a key sign of frontal fibrosing alopecia.
research The lack of significant changes in scalp hair follicle density with advancing age
Aging alone barely affects the number of hair follicles, meaning hair loss is minimal without other conditions like androgenetic alopecia.
research Hair shedding in women: how much is too much?
The hair shedding scale accurately identifies abnormal hair shedding in women with long hair, with grades 5 and 6 indicating excessive shedding.
research Characteristic features of ageing in Korean women’s hair and scalp
