Male pattern baldness may be caused by scalp pressure on hair follicles, which increases with age and leads to a cycle of hair loss. This process is not directly determined by genes.

Hair transplantation effectively treats scalp scars with high success and patient satisfaction.

Combining scalp reduction and hair transplants improves coverage and appearance for male baldness.

PRP or nanofat injections improve scar tissue quality but don't significantly boost hair transplant results for scarring hair loss.

The commentary suggests that using a single-scar technique for hair transplants can give good cosmetic results, but some surgeons hesitate to use it despite ways to address their concerns.

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Early recognition and management of connective tissue diseases like lupus are crucial in young patients.

Doctors should consider SLE in males even if antinuclear antibody tests are negative.

Reconstruct lips with proper planning, templates, and revisions for appearance and function.

Dental pulp stem cells might not reliably become neurons.

PRP may help with aging and osteoarthritis, improving tissue repair and reducing surgery risk.

Hydrogel composites have great potential in regenerative medicine, tissue engineering, and drug delivery.

Cicatricial alopecia, a permanent hair loss condition, is mainly caused by damage to specific hair follicle stem cells and abnormal immune responses, with gene regulator PPAR-y and lipid metabolism disorders playing significant roles.

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.

Incisional slit grafting for hair transplantation gives natural-looking results and has a high success rate.

Testosterone therapy may slightly improve sexual function in postmenopausal women, but its long-term safety is unknown.

Cavity macrophages gather on organ surfaces but don't really invade or help repair the organs after injury.

Selective Androgen Receptor Modulators (SARMs) are drugs that can control the effects of androgens in different tissues, potentially having fewer side effects and promising for treating various conditions.

New techniques have enhanced our understanding of how stem cells function and the role of mutations in aging tissues, which may influence future cancer therapies.

Scientists made structures that look like human hair follicles using stem cells, which could help grow hair without using actual human tissue.

A woman's ovarian tumor causing high testosterone was successfully removed, and her symptoms improved.

Decreased IGF-1R expression may contribute to sacrococcygeal pilonidal sinus development.

New findings suggest targeting IL-23 could treat psoriasis, skin cells can adapt to new roles, direct conversion of skin cells to blood cells may aid cell therapy, removing certain tumor cells could boost cancer immunotherapy, and melanoma may have many tumorigenic cells, not just cancer stem cells.

The conclusion is that accurate diagnosis of different types of hair loss requires good teamwork between skin doctors and lab experts.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Oral retinoids are effective for various skin conditions but have side effects and should not be used during pregnancy.

Skin changes can help diagnose and manage endocrine disorders like thyroid problems, diabetes, and adrenal gland conditions.

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

Extramammary Paget disease can spread deeply into tissues, reaching up to 3.6 mm.
