Eastern Red Bat hair contains various glycerophospholipids, mainly phosphatidylcholine.

Naked hair shafts are significantly associated with scarring hair loss and may help diagnose it, especially when multiple are found.

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.

A Taiwanese patient had hair loss and skin bumps without the usual gene mutation, suggesting other genetic factors might be involved.

Each group of hair follicles on the scalp shares one muscle that helps control hair movement.

The document explains hair and nail biology, common hair loss conditions and treatments, oral and genital skin diseases, and the risks and treatments associated with squamous cell carcinoma.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

Skin stem cells can help improve skin repair and regeneration.

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

Skin diseases are common and can significantly affect people's lives; better outcome measures and ethical clinical trials are needed to improve dermatology care.

Azelaic acid may help treat acne by killing bacteria, reducing inflammation, and preventing clogged pores.

Herbal shampoos clean and improve hair naturally without harmful side effects.

Antiandrogens and androgen inhibitors like spironolactone, finasteride, and dutasteride can treat hair loss and skin conditions, but they have risks and side effects, including potential harm to pregnant women and risks of cancer and heart issues. Herbal remedies also have antiandrogenic effects but lack safety validation.

The document concludes that scalp health is influenced by complex factors affecting sebaceous glands, including hormones, aging, and various substances.

The document explains various skin conditions and their treatments.

Skin stem cells are crucial for maintaining and repairing skin, with potential for treating skin disorders and improving wound healing.

The article concludes that hormonal therapy is an effective long-term acne treatment, even for those without hormonal imbalances.

Hair disease research is a growing and evolving field in dermatology, with recent significant advances.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

Lecithin organogels could be good for applying drugs to the skin because they are stable, safe, and can improve drug absorption.

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

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.

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

Oxidative stress contributes to hair graying and loss as we age.

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

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Trichoscopy is a useful, non-invasive way to diagnose different types of hair loss.

Male pattern baldness involves smaller hair follicles, larger oil glands, and other tissue changes, but not major blood supply issues.

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

Niosomes are promising for skin drug delivery, offering benefits like improved drug penetration and stability.
