Each group of hair follicles on the scalp shares one muscle that helps control hair movement.

The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.

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.

Endoscopic forehead and brow lifting safely and consistently improves aged eyebrows, but may have complications.

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.

Women with androgenetic alopecia have fewer terminal hairs, phenol in nail surgery is safe, and a new hair transplant method is faster and less damaging.

The research provides specific measurements for hair follicles that can improve hair transplant and regeneration techniques.

The curved nonrotary punch is better for hair extraction in people with tightly curled hair.

A new vaccine using a porous scaffold boosts immunity and protects against the flu better than traditional methods.

Skin-derived stem cells grow faster and are easier to obtain than hair follicle stem cells, but both can become various cell types.

Alhydran and DermaCress moisturizers are more effective and cost-efficient for scar hydration than silicone gel.

FUE hair transplants offer minimal scarring and are good for short hairstyles but are time-consuming and can be costly.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

New nanocomposites with copper show promise for healing burn wounds and regenerating skin.

The document concludes that careful surgical methods and choosing the right materials are key for successful scalp, skull, and frontal sinus reconstruction.

EFBL offers hidden incisions, faster recovery, and fewer risks, but may raise hairline and cost more.

New nanofiber technology improves wound healing by supporting cell growth and delivering treatments directly to the wound.

Silver can help prevent and treat infections but its effectiveness varies and should be weighed against costs and side effects.

Facial feminization surgery is effective in helping transgender women appear more feminine and has high patient satisfaction.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.
