Cutting and implanting hair follicles can create finer, more natural-looking hairlines, with about half of the implanted hairs growing back.

The CO₂ laser is better for hair transplantation because it causes less damage than the Ho:YAG laser.

Pattern baldness is likely caused by a dominant gene influenced by testosterone levels, making it more common in men.

Optimal transplant density for Chinese male hair loss patients is 35-50 hair/cm², with minimum 106.88 hair/cm² left in donor area for esthetic satisfaction.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Hair follicle biology advancements may lead to better hair growth disorder treatments.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Common baldness, also known as Androgenetic Alopecia, is caused by a combination of genetic factors and hormones called androgens.

Hair growth is cyclic and influenced mainly by local factors.

Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

Some wound-healing cells can turn into fat cells around new hair growth in mice.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.
