Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.

Different types of sun exposure can damage skin cells and affect healing, with chronic exposure being more harmful, and certain immune cells help in the repair process.

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

Nonpalmoplantar skin cells can be made to express keratin 9 by interacting with palmoplantar fibroblasts.

Effective sunscreen formulations can reduce skin absorption and enhance protection.

Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Tiny particles called extracellular vesicles show promise for treating skin conditions and promoting hair growth.

Scientists turned mouse skin cells into hair-inducing cells using chemicals, which could help treat hair loss.

The skin's microbiome helps hair regrow by boosting certain cell signals and metabolism.

Hair turning darker can be a sign of skin cancer.

Different types of skin cells and immune cells play a role in healing UV-damaged skin, with chronic UV exposure causing lasting damage to certain skin cells.

Acne is linked to complex skin microbe interactions, and new findings suggest microbiome-based treatments could be effective.

Different fibroblasts play key roles in skin healing and scarring.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

Targeting TGFβ can improve skin immunity in older people.

Large-scale fibronectin nanofibers help heal wounds and repair tissue in a skin model of a mouse.

Certain mouse strains develop a skin condition similar to a human hair loss disease due to genetic defects.

Activin B helps heal skin wounds and grow hair by activating a specific cell signaling pathway.

Nanoethosomes can improve the skin penetration of Lidocaine for topical use.

The secretome from mesenchymal stem cells shows promise for treating skin conditions and improving skin and hair health, but more research is needed.

MSCs and their exosomes may speed up skin wound healing but need more research for consistent use.

Boosting β-catenin signaling in certain skin cells can enhance hair growth.

Silk nanofiber hydrogels help stem cells heal wounds faster and improve skin regeneration.

Blocking certain immune signals can reduce skin damage from radiation therapy.

Tiny particles called extracellular vesicles show promise for skin improvement and anti-aging in facial care but face challenges like low production and lack of research.

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.

Zinc pyrithione dissolves quickly on the skin and in hair follicles, especially in smaller particles.

Exosomes show promise for improving wound healing, reducing aging signs, preventing hair loss, and lightening skin but require more research and better production methods.

Adding TERT and BMI1 to certain skin cells can improve their ability to create hair follicles in mice.
