High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

Hair follicle bulge cells don't help skin regrow after glucocorticoid damage; interfollicular epidermis cells do.

Less AgNOR protein production is linked to hair loss.

Skin RAGE levels are linked to inflammation and cell death.

Hair health depends on various factors and hair loss can significantly affect a person's well-being; understanding hair biology is key for creating effective hair care treatments.

Electrospun matrices help regenerate skin and hair follicles using PCL and collagen scaffolds.

Hair growth-related cells need the enzyme SCD1 to help maintain the area that supports hair growth.

The Siah1 and Siah2 genes are active in mouse skin development and hair growth, especially right after birth.

Certain miRNAs might be involved in a hair loss condition called frontal fibrosing alopecia and could possibly help in its diagnosis.

The study found that sweat glands normally suppress immune responses, but this is disrupted in certain skin diseases, possibly contributing to their development.

Finasteride helps female-pattern hair loss.

Fat-related cells are important for initiating hair growth.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Antibiotics can reduce acne but may lead to resistant bacteria, and understanding the skin's bacteria is important for treatment.

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.

Stress can stop hair growth in mice, and treatments can reverse this effect.

Hair loss treatments include medications and new methods like low-level light therapy, which may work by boosting cell activity and blood flow.

Botulinum toxin has potential for treating various skin conditions and improving wound healing.

FA2H is essential for normal fur and sebum production in mice.

Common acne treatments can cause various side effects, like skin irritation and more serious issues, but combination therapies are often more effective and better tolerated.

Over half of the adult women with acne in the study had higher than normal levels of male hormones, especially DHEA.

Antiandrogens can help treat skin conditions like acne and excessive hair in women when used carefully.

The document concludes that new treatments are needed to better manage acne and reduce side effects related to current therapies.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Stem cell therapy is a promising approach for hair regrowth despite potential side effects.

The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.

A complex of 5-aminolevulinic acid and glycyl-histidyl-lysine peptide may help increase hair count in male pattern hair loss without side effects.

Skin problems in PCOS, like excess hair, acne, and hair loss, may not always indicate high male hormone levels and need careful diagnosis for proper treatment.

The conclusion is that Pigmented Epithelioid Melanocytoma can start from hair follicle stem cells or from a mole on the skin.
