Skin surgery has significantly advanced since 1950, with improvements in chemical peels, hair restoration, lasers, and Mohs surgery, and the development of less invasive techniques and specialized training.

Epidermal stem cells show promise for future dermatology treatments due to ongoing advancements.

Some cosmetic procedures show promise for treating hair loss, but more research is needed to confirm their safety and effectiveness.

Lichen planus is a chronic autoimmune disease that is hard to treat and more common in women.

PRP may help hair growth in alopecia areata without major side effects, but more research is needed.

The OVOL1 gene, controlled by β-catenin, is crucial for creating hair follicles.

Plastic surgeons need to understand skin anatomy and physiology to effectively treat aging and diverse skin types.

Using superficial temporal fascia helps prevent Frey syndrome after parotid surgery.

Mast cells likely promote skin scarring and fibrosis, but their exact role is still unclear.

A condition with certain scalp changes may come before acne keloidalis nuchae and other similar hair loss disorders.

Scientists found a way to grow human hair cells in a lab that can create new hair when transplanted.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

Burn reconstruction improves with new techniques, materials, and tissue engineering.

Transplanted baby mouse skin cells grew normal hair using a new, efficient method.

Hair transplant techniques and scalp micropigmentation can effectively hide scars and hair loss after cranial surgery.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Dissecting microscopes give more and better quality hair grafts than magnifying loupes.

The flap assay grows the most natural hair but takes the longest, the chamber assay is hard work but gives dense, normal hair, and the patch assay is quick but creates poorly oriented hair with some issues.

Improving the environment and cell interactions is key for creating human hair in the lab.
