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

Human skin produces sex hormones like estrogen and testosterone, influenced by ARO and StAR, which may affect skin elasticity and hair growth.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Keratinocytes control how melanocytes work.

Human hair matrix cells and dermal papilla fibroblasts can form early hair follicle structures but don't produce hair shafts yet.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Different human hair follicle stem cells grow at different rates and respond differently to a baldness-related compound.

Cholesterol sulfate buildup due to a genetic mutation disrupts the skin barrier, leading to the scaling skin seen in X-linked ichthyosis.

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

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.
