Outer root sheath cells consistently express certain keratins influenced by their environment.
research The cell biology of human hair follicle pigmentation
We need more research on human hair follicle pigmentation, not just mouse models.
research Cultured dermal papilla cells from androgen-dependent human hair follicles (e.g. beard) contain more androgen receptors than those from non-balding areas of scalp
Beard hair follicles have more androgen receptors than non-balding scalp hair follicles.
research VEGF induces proliferation of human hair follicle dermal papilla cells through VEGFR-2-mediated activation of ERK
VEGF promotes hair follicle cell growth through the VEGFR-2/ERK pathway.
research Thyroid Hormones Directly Alter Human Hair Follicle Functions: Anagen Prolongation and Stimulation of Both Hair Matrix Keratinocyte Proliferation and Hair Pigmentation
Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.
research The in vitro properties of dermal papilla cell lines established from human hair follicles
Dermal papilla cells from human hair follicles form unique structures and don't live as long as other skin cells in lab conditions.
research Activation of Transient Receptor Potential Vanilloid-3 Inhibits Human Hair Growth
Activating TRPV3 stops human hair growth.
research 17α‐estradiol induces aromatase activity in intact human anagen hair follicles ex vivo
17α-estradiol boosts aromatase activity in female hair follicles, potentially helping with hair loss.
research Olfactory receptor OR2AT4 regulates human hair growth
A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.
research Correlation of cortisol in 1-cm hair segment with salivary cortisol in human: hair cortisol as an endogenous biomarker
Hair cortisol levels can reflect salivary cortisol levels in humans.
research Thyrotropin releasing hormone (TRH): a new player in human hair‐growth control
TRH stimulates human hair growth and extends the hair growth phase.
research Sequences and differential expression of three novel human type-II hair keratins
Hair differentiation starts earlier than thought, involving multiple type-II keratins.
research Oxidative Damage Control in a Human (Mini-) Organ: Nrf2 Activation Protects against Oxidative Stress-Induced Hair Growth Inhibition
Activating Nrf2 protects human hair follicles from oxidative stress and helps prevent hair growth inhibition.
research A neuroendocrinological perspective on human hair follicle pigmentation
Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.
research Profiling the Response of Human Hair Follicles to Ultraviolet Radiation
UVB radiation harms hair growth and health, causing cell death and other changes in human hair follicles.
research In vitro characterization of human hair follicle dermal sheath mesenchymal stromal cells and their potential in enhancing diabetic wound healing
DS-MSCs from hair follicles may improve diabetic wound healing.
research Chronological ageing of human hair keratin fibres
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Estrogens and Human Scalp Hair Growth—Still More Questions than Answers
The effects of estrogen on human hair growth are unclear and need more research.
research Effect of ethnicity and treatments on in situ tensile response and morphological changes of human hair characterized by atomic force microscopy
