Hair helps prevent scalp skin cancer by supporting immune protection.

Skin can produce blood cells, often due to disease, which might lead to new treatments for skin and blood conditions.

Hair protects the scalp from skin cancer by aiding immune defense.

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.

Minoxidil affects cell growth in two ways: low doses increase growth, while high doses slow it down and can be toxic.
