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

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

Proteins from stem cells improved hair growth in patients with hair loss.

Hair follicle stem cells are promising for wound healing but require more research for safe clinical use.

Scientists made stem cells that can grow hair by adding three specific factors to them.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

Stem-cell therapy shows promise for skin conditions but needs more research.

Stem cell therapies show promise for hair regrowth but need more research to confirm effectiveness.

Bead-jet printing of stem cells improves muscle and hair regeneration.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Understanding how epigenetic regulation affects stem cells is key to cancer insights and new treatments.

IL-6 from stem cells helps repair skin and grow hair.

Low-level laser therapy improves hair growth and dermal papilla cell function.

Hair follicle stem cells might help treat traumatic brain injury.

A protein called desmoglein 3 is important for keeping hair follicle stem cells inactive and helps in their regeneration.

Blocking Prostaglandin D₂ may help treat hair loss.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Different skin stem cells help heal wounds, with hair follicle cells becoming more important over time.

Minoxidil boosts hair growth by triggering growth factor release from specific stem cells.

CD34+ and CD34- melanocyte stem cells have different regenerative abilities.

Different types of cell death affect skin health and inflammation, and understanding them could improve treatments for skin diseases.

Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.

Exosomes from skin cells can boost hair growth by stimulating a gene called LEF1.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

TAF4 is important for skin cell growth and helps prevent skin cancer in mice.

Lab-made tissues from dog fat stem cells can help grow hair by releasing a growth factor.

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.
