Scalp medical tattooing effectively camouflages bifid parietal whorls.

Pica disorder in central Iraq is mainly found in females and is linked to low iron levels; treatment with iron improves most patients.

Researchers found a genetic link for hereditary hair loss but need more analysis to identify the exact gene.

Stress and hormones like progesterone can affect absence seizures, but their effects change with different life stages.

Hair transplants can cause hair loss if done while lichen planopilaris is active; wait until it's inactive for two years and check with a scalp biopsy first.

The guidelines recommend informed consent for gender-affirming treatments and stress the importance of personalized, culturally sensitive care for transgender individuals.

Dehydroepiandrosterone (DHEA) is a prohormone important for producing sex steroids and has potential health benefits.

Testosterone is important for men's sexual function, may help some women's sexual desire, while other hormones and neurotransmitters also play complex roles in sexual behavior.

Human skin can make serotonin and melatonin, which help protect and maintain it.

The document concludes that mouse models are helpful but have limitations for skin wound healing research, and suggests using larger animals and genetically modified mice for better human application.

Growing human skin cells in a 3D environment can stimulate new hair growth.

Noggin is necessary to start the hair growth phase in skin after birth.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Special fiber materials boost the healing properties of certain stem cells.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Silver can help prevent and treat infections but its effectiveness varies and should be weighed against costs and side effects.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

The drug IPI-926 is safe at 160 mg daily and may help treat certain tumors, especially basal cell carcinoma.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

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.

Stress can stop hair growth in mice, and treatments can reverse this effect.

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

More men are getting benign prostatic hyperplasia, and there are many treatments, from medication to surgery, with new methods being developed.

Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.

Scientists created stem cells that can grow hair and skin.

No treatment fully prevents hair loss from chemotherapy yet.

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

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.
