Trichoscopy is useful for diagnosing and monitoring alopecia areata treatment.

Camellia japonica extract may improve scalp health and promote hair growth.

DHT may reduce inflammation caused by certain bacteria in skin cells.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

Prolactin may affect hair growth differently based on gender and scalp area.

ATP increases melanin production in skin after UV exposure, with the P2X7 receptor being crucial for this process.

Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.

Estazolam reduces anxiety-like behavior in PTSD by increasing allopregnanolone levels.

DHT affects bone growth by altering gene activity in osteoblasts, potentially complicating steroid use.

A compound from brown algae boosts the production of a certain inflammatory substance in skin cells.

A specific gene mutation is linked to a hereditary form of dystonia that responds well to certain medications.

Human skin has less GDNF and its receptor with age.

Backhousia citriodora leaf extract effectively reduces oily skin across different ethnic groups.

Finding functions for unknown GPCRs is hard but key for making new drugs.

Annurca apple extract may help treat hair loss and protect against oxidative stress.

The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.

Aging causes skin stem cells to work less effectively.

The document concludes that adenosine receptor agonists have potential for treating various conditions, but only a few are approved due to challenges like side effects and the need for selective activation.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

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.

Formyl-peptide receptor agonists could be new anti-inflammatory drugs.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

The study concludes that the EDA2R gene is activated by p53 during chemotherapy but is not necessary for chemotherapy-induced hair loss.

Mice that can regenerate tissue have cells that pause in the cell cycle, which is important for healing, similar to axolotls.

Sonidegib and vismodegib are similarly effective for advanced basal cell carcinoma, but sonidegib might have a slightly better safety profile.

Teriflunomide effectively reduces relapses and disability in MS and has a manageable safety profile.

Combining cosmetic procedures with lifestyle changes improves antiaging results.

Active oxygen species might be involved in skin tumor growth, but their exact role is unclear.

Researchers created immortal human skin cells with constant testosterone receptor activity to study hair loss and test treatments.

Removing the ROBO4 gene in mice reduces skin inflammation and hair loss by affecting certain inflammation pathways and gene expression.
