The back of the scalp has more nerve fibers than the front, which may explain why some people feel more sensitivity there.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.

Follicular Unit Extraction (FUE) hair transplant is less invasive, leaves no scars, and has quicker recovery times, but it's more time-consuming and challenging. Automation helps speed up the process and improve graft survival, reducing the need for traditional strip surgery.

Hair transplant techniques and scalp micropigmentation can effectively hide scars and hair loss after cranial surgery.

Hair transplants help transgender patients look more like their gender identity, with different procedures for trans women and men.

Minoxidil 2% and 5% are common treatments for female pattern hair loss, with other options including anti-androgens, oral contraceptives, and hair transplantation.

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.

A new method using Y-27632 improves the growth and quality of human hair follicle stem cells for tissue engineering and therapy.

Deep learning can accurately automate hair density measurement, with YOLOv4 performing best.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Light therapy might help treat hereditary hair loss by improving hair follicle growth in lab cultures.

FUT-MD hair transplants have higher follicle survival rates than FUE transplants.

Ergonomic improvements in hair transplant surgery reduce discomfort for surgeons and may improve patient outcomes.

Sheep-derived factors improve human hair cell clustering, which may help hair growth.

Primary cicatricial alopecia, a rare disorder causing permanent hair loss, is hard to diagnose and treat, with treatments like anti-inflammatory drugs and steroids offering varied results and no guaranteed cure. Psychological support for patients is important, and future research should aim to identify causes of the condition.

PRP or nanofat injections improve scar tissue quality but don't significantly boost hair transplant results for scarring hair loss.

Stem cell therapies could be a promising alternative for hair loss treatment, but more research is needed to understand their full potential and safety.

The document concludes with the creation of a Hair Transplant Foundation after reviewing the early hair transplant techniques and discussions from a forum.

The review suggests that a special cell-derived treatment shows promise for various skin conditions and hair growth but needs more research for confirmation.

Hair loss due to scarring can be treated by reducing inflammation, removing scar tissue, and transplanting hair. The Follicular Unit Extraction technique is effective but requires skill and time. Future focus should be on scar-less healing methods.

Most patients stop using topical minoxidil due to side effects.

No CD44 in alopecia areata, present in normal and androgenetic alopecia.

Indonesia's dermatologic surgery training program aims to improve patient care by educating skilled surgeons.
