330-360 / 1000+ resultsresearch Delayed Telogen Replacement in a Boy’s Scalp
Androgens may worsen a natural hair resting phase, possibly leading to hair loss.
research Expression pattern of human hair keratin basic 1 (hHbl) in hair follicle and pilomatricoma
hHbl gene is active in hair shaft cells and some pilomatricomas.
research Exogen Hairs in Women with and without Hair Loss
Women with and without hair loss have similar amounts of exogen hairs, so these hairs are not a key factor in hair loss conditions.
research Female hair concerns with age
As women age, they experience changes in hair density and volume, face challenges in distinguishing normal hair loss from disease, and have limited access to treatments for hair issues.
research Sudden whitening of the hair in an 82-year-old woman: the ‘overnight greying’ phenomenon
An 82-year-old woman's hair turned white suddenly, likely due to a rare form of alopecia that targets pigmented hair.
research The Ultrastructure of Tissue Attached to Telogen Hair Roots
Recognizing specific tissue types on telogen hair roots can improve DNA typing.
research PREMATURE HAIR GRAYING: FACTORS THAT CONTRIBUTE THE MECHANISMS OF THE PROCESS
Premature hair graying is caused by various factors and mechanisms.
research Congenital hypotrichosis due to short anagen
Some children are born with unusually short, fine hair because their hair growth phase is short, but this often gets better by itself during puberty.
research 804 Human hair follicles operate core elements of a functional peripheral equivalent of the central hypothalamic-pituitary-thyroid axis
Human hair follicles have their own thyroid hormone system.
research Human hair morphology: a scanning electron microscopy study on a male Caucasoid and a computerized classification of regional differences.
Hair varies in size and features depending on body region.
research Characterization and Chromosomal Localization of Human Hair-Specific Keratin Genes and Comparative Expression During the Hair Growth Cycle
Two specific hair keratin genes are active during hair growth and decline as hair transitions to rest.
research Changes in Characteristics of Murine Hair Follicles and Tissue Stem Cells Throughout Life
Mouse hair follicles age, causing more white hairs due to fewer pigment stem cells.
research Research Snippets
New hair regrowth model introduced, imiquimod kills skin cancer cells, T-cadherin loss makes skin cancer more invasive, no strong link between PTCH1 gene and skin cancer after transplant, and male teens more likely to have hereditary hair loss.
research The Transplanted Hairline
Leg hair transplants can create a natural-looking hairline and show successful growth over several years.
research Some electron microscope observations on hardening in the human hair follicle
The hair follicle structure is more complex than thought, with new findings on protein formation.

Females have higher estrogen receptor levels in hair than males, and these levels decrease in white hair compared to black hair.
research Pohl-Pinkus constrictions of hair following chemotherapy for Hodgkin's disease
Chemotherapy caused the patient's hair to have alternating thick and thin segments.
research Towards a “free radical theory of graying”: melanocyte apoptosis in the aging human hair follicle is an indicator of oxidative stress induced tissue damage
Oxidative stress causes hair to gray by damaging and killing pigment cells.
research Short anagen syndrome in a girl with curly dark hair and consanguineous parents
A 3-year-old girl has short anagen syndrome, causing her hair to stay short.
research Hair Counts from Normal Scalp Biopsy in Taiwan
The conclusion is that normal scalp hair counts for Taiwanese people were established, showing age-related differences but not sex or scalp location differences.
research Neuroendocrinology of the hair follicle: principles and clinical perspectives

Hormone therapy increases facial and body hair in transgender men, while hair removal improves well-being in transgender women, but cost is a barrier as insurance often doesn't cover it. Dermatologists can use various treatments for these hair issues.
