Researchers used a laser to create advanced skin models with hair-like structures.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

Red Ginseng Extract helps hair grow and improves skin health by stimulating cell growth and enhancing the body's antioxidant defense system.

Human fetal placental stromal cell injections speed up healing and improve skin and hair recovery after radiation damage.

The 675 nm laser effectively improved facial acne scars in dark skin with minimal side effects.

Wnt-3a helps grow more skin stem cells, which could lead to new hair loss treatments.

Meis2 is essential for touch sensation and nerve function in mice.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

Skin cell behavior is influenced by the tightness of nearby cells, affecting their growth and development.

Sleep problems and skin issues affect each other; poor sleep can worsen skin conditions, and some skin treatments can improve or harm sleep quality.

Hair and nails are skin parts that develop early and serve protective and functional roles.

A protein called FGF9 helps regenerate hair follicles in mice after skin damage, and increasing FGF9 could potentially help human hair growth.

TGFα gene mutation in mice causes abnormal skin, wavy hair, curly whiskers, and sometimes eye inflammation.

Skin grafting and wound treatment have improved, but we need more research to better understand wound healing and create more effective treatments.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Natural products in cosmetics are beneficial for skin and hair care with low toxicity.

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

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Polymeric nanoparticles show promise for treating skin diseases.

Seaweeds have beneficial compounds for skin care, including anti-aging and protective effects.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Cannabinoids may help treat various skin conditions.

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.

Skin aging is a complex process influenced by various factors, leading to wrinkles and sagging, and should be considered a disease due to its health impacts.

Surgical face-lifts are more effective, but fractional radiofrequency is a good, less invasive alternative for treating skin laxity.

The research improved understanding of hair and skin properties across different ethnicities and conditions.

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

Human hair and skin friction vary by ethnicity, hair type, and environmental conditions.

Skin fat helps with body temperature control and has other active roles in health.

Skin problems in COVID-19 patients are rare and may be due to the body's complex immune response or blood clotting issues.
