research Managing hair loss in midlife women
The conclusion is that proper evaluation and treatment of hair loss in midlife women is important, considering the emotional impact and potential for various treatments.
research Lipid peroxides induce early onset of catagen phase in murine hair cycles
Lipid peroxides can cause early hair loss by damaging hair follicles.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research Foxp1 Regulates the Proliferation of Hair Follicle Stem Cells in Response to Oxidative Stress during Hair Cycling
Foxp1 helps control hair stem cell growth and response to stress during hair growth cycles.
research Protective effects of human umbilical cord blood‑derived mesenchymal stem cells against dexamethasone‑induced apoptotic cell death in hair follicles
Stem cells from umbilical cord blood may prevent hair loss caused by certain medications.
research Paracrine crosstalk between human hair follicle dermal papilla cells and microvascular endothelial cells
Cells from the base of hair follicles help blood vessel cells survive and grow, which is important for healthy hair.
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 Modeling Oxidative Stress–Linked Telogen Effluvium: A Monte Carlo Simulation Using Published Trichoscopy Norms and Cannabis Exposure Distributions
Higher cannabis use may be linked to more severe hair loss.
