Coconut oil protects hair from damage better than regular grooming practices.
research Dexpanthenol Promotes Cell Growth by Preventing Cell Senescence and Apoptosis in Cultured Human Hair Follicle Cells
Dexpanthenol helps human hair follicle cells grow by preventing aging and death, and by supporting growth signals.
research Results of 60-second timed hair counts in women between the ages of 20–60 years
The 60-second timed hair count is a reliable and simple way to measure hair shedding at home, showing older women tend to shed more hair than younger women.
research Do follicles matter? Testing the effect of follicles on hair cortisol levels
Hair follicles increase hair cortisol levels, so consistent hair collection methods are important.
research VDR is an essential regulator of hair follicle regression through the progression of cell death
Vitamin D Receptor is crucial for hair follicle shrinkage and cell death, affecting hair growth.
research A single arm, exploratory and pilot study to evaluate the efficacy of a multi-component water-based herbal supplement in hair growth, density, follicle strength and hair fall in healthy male and female subjects
The herbal supplement improved hair growth, density, and strength without side effects.
research Age-related changes in the dorsal skin histology in Mini and Wistar rats.
Mini rats have thinner skin, more fat, and different hair cycles than Wistar rats due to lower growth hormone levels.
research Human hair follicles display a functional equivalent of the hypothalamic‐pituitary‐adrenal (HPA) axis and synthesize cortisol
Human hair follicles can produce cortisol like the body's stress response system.
research [An immunohistochemical study on the normal human anagen hair and hair follicle using anti-hair keratin monoclonal antibodies (HKN-5, HKN-6, HKN-7 and HKN-8)].

research Identification of factors contributing to phenotypic divergence via quantitative image analyses of autosomal recessive woolly hair/hypotrichosis with homozygous c.736T>ALIPH mutation
Different hair fiber development might explain why hair loss severity varies in patients with a specific genetic mutation, and treatments that thicken hair could help.
research Abstract # 1697 Hair cortisol concentrations associate with hair growth rate
Hair cortisol levels can indicate stress and are affected by washing frequency, not cosmetic treatments.
research Abnormal expression of VDR in the hair follicle of alopecia areata
Low Vitamin D receptor levels in hair follicles may contribute to alopecia areata.
