research Hair through the female life cycle
Women's hair generally gets thinner and less dense starting in their mid-thirties, with hair loss becoming more common as they age due to both genetics and environment.

research Critical study of hair growth analysis with computer-assisted methods
The Trichoscan system was found to be inaccurate for measuring hair growth, needing better software to be useful.
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 Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.

research The clinical management of hirsutism
The document concludes that managing hirsutism involves identifying the cause, using a scoring system for severity, combining cosmetic and medical treatments, encouraging weight loss, and providing psychological support, while noting the need for more research on drug treatments.
research Protein disulphide isomerase-mediated grafting of cysteine-containing peptides onto over-bleached hair
PDI helps restore over-bleached hair's strength and structure by attaching special peptides.
research Immune cell regulation of the hair cycle
Immune cells affect hair growth and could lead to new hair loss treatments.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.
research Raman spectroscopy and electronic microscopy structural studies of Caucasian and Afro human hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
research Hair care practices and structural evaluation of scalp and hair shaft parameters in African American and Caucasian women
African American women report more hair issues and use different hair care practices than Caucasian women, and have different hair and scalp characteristics.
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 Evidence for biological shaping of hair ice
A fungus is essential for forming and shaping hair ice on dead wood.
research Study of seed hair growth in Populus tomentosa, an important character of female floral bud development
Poplar seed hairs grow from the placenta at the ovary base, with endoreduplication playing a key role in their development, and share similar cellulose synthesis processes with cotton fibers.
research Keratin‐based particles for protection and restoration of hair properties
Keratin-based particles safely improve hair strength, smoothness, and heat protection.
research Molecular modeling and structural characterization of a high glycine–tyrosine hair keratin associated protein
The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.
research LC-ESI-QTOF-MS/MS characterization of phenolic compounds from Prosopis farcta (Banks & Sol.) J.F.Macbr. and their potential antioxidant activities
Prosopis farcta has strong antioxidants, useful for food and medicine.
research Hair follicle transcriptome profiles during the transition from anagen to catagen in Cashmere goat (Capra hircus)
The transition from growth to regression in Cashmere goat hair follicles involves changes in expression of genes related to keratin and cell differentiation.
research Role of platelet rich plasma gel in the wound healing of black Bengal goat
Homogenous PRP gel heals goat skin wounds best, promoting quick recovery and hair growth.
research Gender differences in scalp hair growth rates are maintained but reduced in pattern hair loss compared to controls
Women's hair grows faster and thicker than men's, but hair growth slows for both genders with pattern hair loss.
research Improvement of androgenetic alopecia with topicalSophora flavescensAiton extract, and identification of the two active compounds in the extract that stimulate proliferation of human hair keratinocytes
Sophora flavescens extract helps hair growth and treats hair loss.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Abnormal Wool Growth and Alopecia of Artificially Reared Lambs
Lambs fed a liquid diet showed abnormal wool and skin, which improved with more B-vitamins, suggesting a link to B-vitamin deficiency.
