Hairless mice have longer hair follicles and abnormal structures during the catagen phase.
research Avaliação quantitativa em cortes histológicos transversais do couro cabeludo
The study found average numbers for different types of hair follicles in the scalp and observed differences between men and women, suggesting reasons for more common hair shedding in women.
research Age-Related Changes in Female Scalp Dermal Sheath and Dermal Fibroblasts: How the Hair Follicle Environment Impacts Hair Aging
Aging causes changes in the scalp that can affect hair growth and lead to older-looking hair in women.
research Trichoscopy in Asian Patients
Asian patients show different trichoscopy features compared to Caucasians, like thicker hair and different alopecia signs.
research 성장기 모낭에서 큐티클층의 각질화 과정
The cuticle layer in hair follicles thickens during keratinization due to incomplete cytosol loss.
research “Cloned” Hairlines
Cutting and implanting hair follicles can create finer, more natural-looking hairlines, with about half of the implanted hairs growing back.
research Normal head-hair length is correlated with its diameter
Hair length and thickness are related, with thickness peaking at about a quarter of the hair's maximum length.
research New aspects of the structure of human hair on the basis of optical microscopic observations of disassembled hair parts.
Human hair's strength comes from a honeycomb-like structure and macrofibrils.
research TRICHOSTASIS SPINULOSA
Trichostasis spinulosa mainly affects the nose, with many tiny hairs in one follicle, possibly influenced by hormones and sunlight.
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 Features of structure of external layer of murine hair at different stages of malignant tumor development
Hair structure worsens as tumors grow in mice.
research Clinical, trichoscopic, and histopathologic characteristics of patients with alopecia and hypothyroidism: An observational study
Hypothyroidism patients with hair loss typically have thinning hair, smaller hair follicles, and normal hair shedding.
research Quantitative study of the human hair follicle in normal scalp and androgenetic alopecia
Alopecia causes smaller hair follicles and affects growth-related structures.
research Selective follicular targeting by modification of the particle sizes
Medium-sized particles penetrate hair follicles better than smaller or larger ones, which could improve delivery of skin treatments.
research Supplementary Material for: Life of the B10 mouse: a view from the hair follicles and tissue stem cells
Mouse skin and hair aging starts at 200 days, with changes in hair follicles and more white hairs as signs of aging.
research Analysis of the hair coat of domestic catswith special focus on histological structure
Domestic cat hair varies in thickness and length, with guard hairs being longest and thickest, and all hair types mainly contain keratin.
research Gross morphology and ultrastructural characterization of the skin in Yuyi hairless mice(Mus musculus)
Yuyi hairless mice lose hair after birth, develop thick, loose skin with folds, and show disorganized skin structure as they age.
research Three-dimensional ultrastructural analysis of human skin with the arrector pili muscle interacting with the hair follicle epithelium
The method effectively analyzes skin tissue changes, especially in the arrector pili muscle and nerve fibers with hair follicles.
research Exploring Mechanical Niches Identified by Hair Follicle Compression and How These Transduce Proliferation and Differentiation Cues in Epidermally Derived cells.
Less stiff collagen promotes higher cell growth in hair follicles.
research Faculty Opinions recommendation of De novo production of dermal papilla cells during the anagen phase of the hair cycle.
New cells join the hair's dermal papilla during the growth phase, possibly affecting hair thickness.
