Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.

Aging scalp skin contributes to hair aging and loss, and more research is needed to develop better hair loss treatments.

Minoxidil can help thicken hair in some people with male pattern baldness, especially if used early and continuously.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Eastern Red Bat hair contains various glycerophospholipids, mainly phosphatidylcholine.

Hormonal treatments can help with hair loss, acne, and excess hair growth, but it takes 3-6 months to see results and patients should know the possible side effects.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

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.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

Prolactin may be important for skin growth and immune function.

The arrector pili muscle might play a role in hair loss and needs more research to understand its impact.

Researchers created a skin treatment that could effectively deliver medication into hair follicles.

Lizards can regrow their tail scales with the same structure, distribution, and gender-specific features as the original ones, and this unique ability is not seen in adult mammals.

The method allows for 3D tracking of hair follicle stem cells and shows they can regenerate hair for up to 180 days.

New treatments for skin diseases are more effective and patient-friendly, but many still lack a cure.

Human hair cells can be used to grow new hair on rat ears, suggesting a possible treatment for hair loss.

Blood-derived CD34+ cells speed up healing, reduce scarring, and regrow hair in skin wounds.

Pellagra, caused by niacin deficiency and presenting with photosensitivity, should be considered in patients with relevant symptoms and risk factors.

Finasteride increases hair count and improves hair growth with low risk of side effects.

Most skin tumors in the study were benign, with squamous cell carcinoma being the most common malignant type.

Proper care and diet are crucial to prevent health issues in gerbils.

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

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

Too much androgen can cause hair loss; finasteride may help.

Nanoparticles can improve skin treatments by better targeting hair follicles, but more research is needed for advancement.

Hair follicle stem cells are a promising source for tissue repair and treating skin or hair diseases.

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

Effective hair loss assessment requires a mix of precise measurement methods.

An extract from Quercus acutissima bark was found to reduce sebum production and block an enzyme linked to acne.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.
