The document recommends using both clinical evaluation and various measurement methods to assess skin greasiness, considering factors like temperature and hormones.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Different types of stem cells and their environments are key to skin repair and maintenance.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Electrolysis is effective for permanent hair removal, but technique is key to avoid scarring, and sometimes hormonal treatment is needed for women with hirsutism.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

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

Probiotic bacteria improved skin and hair health in aged mice.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Dexamethasone speeds up hair loss in mice, while cyclosporin A slows it down.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

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

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Hormones, especially androgens, play a big role in acne, but most acne sufferers don't have a hormone disorder. Hormonal treatments, including birth control pills, can be very effective for women whose acne doesn't improve with regular treatments.

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

Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.

Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

Liposomes could improve how skin care products work but are costly and not very stable.

New treatments targeting specific genes show promise for treating keratin disorders.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Researchers found that hair shedding happens mostly when new hair is growing and involves a unique process.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

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