Micrografts and minigrafts for hair restoration provide high patient satisfaction and can cover large areas of hair loss, including sideburns, eyebrows, and beards.

PRP treatment increased hair density, especially in men and younger patients with AGA.

3% hydrogen peroxide does not harm hair graft survival compared to saline.

Blocking Rab27a slows hair growth, while blocking Rab27b encourages it.

Hair transplantation has evolved to refined techniques like FUE and FUT, with Finasteride and Minoxidil as the only other proven treatments for hair loss.

Using both follicular units and slit grafts for hair transplants may give better hair density and graft survival.

Bobby Limmer was crucial in developing a hair transplant method that uses natural hair groupings for a more realistic look.

Both sutures and staplers are equally effective for hair transplant donor area closure, but staplers are faster and easier to use.

Hair transplants are effective for male and female pattern baldness, have evolved in technique, and require careful planning for natural results and managing complications.

Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.

FUE is a less invasive hair restoration method with potential to become standard, offering benefits like reduced scarring and pain, but requires experience to minimize risks.

High-density hair transplants can have high survival rates with improved techniques, but lower densities might also give good results.

Surgical hair restoration has improved since 1959, with new techniques like minigrafts, micrografts, and scalp reductions creating more natural hairlines and reducing bald skin, despite some risks and potential for scarring.

Transplanting skin cells is a safe, effective, and affordable treatment for vitiligo.

New hair loss treatments show promise, but more research is needed to confirm their effectiveness.

DNMT3A is crucial for healthy skin and hair growth.

Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.
