Trichoscopy helps tell apart scalp lesions in pemphigus vulgaris and pemphigus foliaceus and is useful for choosing biopsy locations.

Trichoscopy is a quick, accurate, and non-invasive method to diagnose and treat non-scarring hair loss.

Scalp involvement is common in pemphigus and can lead to hair loss, with the severity of scalp lesions linked to overall disease severity.

Most patients with autoimmune blistering diseases experienced some hair loss, which may be underreported and linked to disease severity.

Trichoscopy helps quickly identify autoimmune diseases on the scalp but should be used with other standard tests.

Reflectance confocal microscopy is useful for diagnosing and monitoring skin diseases, but it has limitations and requires expertise for correct use.

Androgenetic alopecia involves immune cell disruptions, especially increased CD4+ T cells around hair follicles.

Applying a specific inhibitor lightens skin and hair color.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Scalp melanoma is more common and easier to diagnose early in people with androgenetic alopecia due to sun damage.

Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.

The document concludes that specific dermoscopic features can help diagnose different facial red skin conditions.

Skin structure complexity and variability are crucial for assessing skin toxicity in safety tests.

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

The document explains how hair follicles develop, their structure, and how they grow.

The skin is vital for protection, temperature control, fluid balance, immunity, and sensing, with damage affecting daily life and mental health.

Human hair keratins can be turned into useful 3D biomedical scaffolds through a freeze-thaw process.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Dermatoscopy is useful for identifying different hair and scalp conditions and can reduce the need for biopsies.

A rare benign skin tumor showed unusual features of sebaceous and sweat glands, important for correct diagnosis.

Dermoscopy is a useful tool for identifying features of skin conditions, but more research is needed to define its role in dermatology.

Treatments for permanent hair loss from scarring aim to stop further loss, not regrow hair, and vary by condition, with partial success common.

The skin is a complex barrier that protects the body, regulates temperature, and helps with immune responses.

Reflectance confocal microscopy is a useful, non-invasive tool for diagnosing some skin diseases, with potential for future improvements.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

The document concludes that various clinical methods are used to assess ageing skin and the effectiveness of anti-ageing products.

There are still challenges in diagnosing and treating chronic skin diseases, but there is hope for future improvements.

Understanding the genetics of rare inherited ichthyosis syndromes is key for better treatments and genetic counseling.

Cell-based therapies using dermal papilla cells and adipocyte lineage cells show potential for hair regeneration.

Wnt1a helps keep cells that can grow hair effective for potential hair loss treatments.
