Visible light can damage skin and most sunscreens don't block it well; more research is needed on its effects and protection methods.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.

Some herbal therapies may help with skin conditions, but more research is needed to confirm their safety and effectiveness.

Androgens may cause hair loss by increasing TGF-beta1 from scalp cells, which inhibits hair cell growth.

Estrogens can improve skin aging but carry risks; more research is needed on safer treatments.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

Researchers created human hair follicles using a new method that could help treat hair loss.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

New effective scar treatments are urgently needed due to the current options' limited success.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

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

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

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

Fibromodulin might help reduce scarring if increased in adult wounds like in fetal skin that heals without scars.

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.

Blocking JAK-STAT signaling can lead to hair growth.

Some skin medications are safe during pregnancy and breastfeeding, but others can harm the baby and should be avoided.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Accurate diagnosis and effective oral treatment are key to managing tinea capitis and preventing its spread.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Congenital Adrenal Hyperplasia is a genetic disorder with two forms, causing symptoms like early puberty and severe acne, but can be identified through screening and treated with glucocorticoids.

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