A substance called VIP might protect hair follicles from being attacked by the immune system, and problems with VIP signaling could lead to hair loss in alopecia areata.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

The document concludes that hair follicles have a complex environment and our understanding of it is growing, but there are limitations when applying animal study findings to humans.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Researchers found that bulge cells from human hair can grow quickly in culture and have properties of hair follicle stem cells, which could be useful for skin treatments.

Hair follicle damage happens during hair transplants and can impact success; better surgical methods are needed.

NFIC helps rat dental cells grow and turn into bone-like cells.

Outside factors like grooming, chemicals, and the environment can damage hair and cause disorders.

Hair growth is influenced by factors like genetics and nutrition, and more research is needed to understand hair loss and growth mechanisms.

Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.

The document concludes that hair loss is common and can be treated with medications like minoxidil or surgical options, and it significantly affects people's psychological well-being.

Korean hair is typically thicker with a slower growth rate, and treatments like Dutasteride are effective for male pattern hair loss without major side effects.

The document concluded that FDA-approved treatments like minoxidil and finasteride are effective for hair loss, while the effectiveness of natural remedies and other non-approved treatments is not well-supported by evidence.

Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.

Testosterone and dihydrotestosterone affect hair growth, and new techniques like the folliculogram help study it, but fully understanding hair growth is still complex.

Zinc deficiency disrupts hair growth and cycle, but zinc supplements can fix this.

Hair growth and pigmentation in mice involve specific stages crucial for research.

Certain immune cells in the skin release a protein that stops hair growth by keeping hair stem cells inactive.

Researchers developed a quick and easy way to get and grow cells from the base of human hair follicles.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

MicroRNA-148a is crucial for maintaining healthy skin and hair growth by affecting stem cell functions.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Hair follicles can regenerate after radiation damage but not during a specific growth phase.

M-CSF-stimulated myeloid cells can turn into skin cells and help heal wounds and regrow hair.

TGF-β2 helps activate hair follicle stem cells by counteracting BMP signals.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

mTOR signaling helps activate hair stem cells by balancing out the suppression caused by BMP during hair growth.

The conclusion is that Fgf18 and Tgf-ß signaling could be targeted for hair loss treatments.
