Dutasteride and finasteride can help increase hair growth gene expression but need further improvement.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

A protein called sFRP4 can slow down hair regrowth.

Hair follicle stem cells change states with age, affecting hair growth and aging.

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

PKC ε increases hair follicle stem cell turnover and may raise skin cancer risk.

Stress, nutritional issues, and chronic diseases can cause hair loss, and nail changes may signal internal diseases; treatment focuses on the underlying cause.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.

α3β1-integrin is crucial for maintaining normal hair follicle shape and function but not needed for the development of the surrounding skin.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

Injected cells show potential for hair growth.

The new microwell device helps grow more hair stem cells that can regenerate hair.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

Researchers developed a method to grow hair follicles using special beads that could help with hair loss treatment.

Understanding hair follicle biology and stem cell control could lead to new hair loss treatments.

Medium-sized particles penetrate hair follicles better than smaller or larger ones, which could improve delivery of skin treatments.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.

Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.

Dog hair follicle stem cells can turn into fat cells.

Caffeine can protect scalp hair follicles from damage caused by UV radiation.

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

Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.

Human hair follicles can regenerate after removal, but with low success rate.

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

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Hair disorders are caused by a complex mix of biology, genetics, hormones, and environmental factors, affecting hair growth and leading to conditions like alopecia.

Endoglin is crucial for proper hair growth cycles and stem cell activation in mice.

Stem cells can help regenerate hair follicles.
