Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

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.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Modern hair restoration techniques have evolved from punch grafting to methods like micro-grafting and follicular unit transplantation, but they are labor-intensive, expensive, and can lead to patient dissatisfaction. Future treatments may involve cloned hair follicles and drugs like finasteride.

Combining scalp reduction and hair transplants improves coverage and appearance for male baldness.

A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.

Pubic hair transplantation can help women with little to no pubic hair, using scalp hair for a natural look and requires careful aftercare.
