Male and female skin differ in many ways, which could lead to gender-specific skin treatments.

Early diagnosis and treatment, using finasteride, minoxidil, or hair transplantation, improves hair loss outcomes.

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.

Aging causes skin stem cells to work less effectively.

Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

Microneedles help improve skin appearance and deliver skin treatments effectively, but safety concerns need more research and regulation.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Fat cells in the skin help start healing and form important repair cells after injury.

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

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.
