Immune cells around hair follicles help control hair growth and could be targets for treating hair disorders.

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.

Hair color is determined by different melanins and changes with age.

Low-level laser treatment helps mice grow hair by increasing certain protein levels linked to hair growth.

Treat pattern hair loss with finasteride and topical minoxidil.

A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.

Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

The gene Foxn1 is important for hair growth, and understanding it may lead to new alopecia treatments.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Oxidative stress contributes to hair graying and loss as we age.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Muscles and nerves that cause goosebumps also help control hair growth.

Four genetic risk spots found for hair loss, with WNT signaling involved and a link to curly hair.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Light can turn on hair growth cells through a nerve path starting in the eyes.

Oxidative stress damages hair and contributes to aging, and managing it can help maintain hair health.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

Cholesterol balance is important for hair health, and problems with it can lead to hair loss conditions.

Runx1 controls fat-related genes important for normal and cancer cell growth, affecting skin and hair cell behavior.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

The study concluded that hair growth in mice is regulated by a stable interaction between skin cell types, and disrupting this can cause hair loss.
