Lasers in hair transplantation show promise but are not yet standard, with current methods causing some side effects and needles still being preferred for creating recipient sites.

Most men's multi-hair follicles naturally stand perpendicular to a line from the top of their head, which is important for natural-looking hair transplants.

New treatments for vitiligo may focus on protecting melanocyte stem cells from stress and targeting specific pathways involved in the condition.

Many Iraqi patients had skin problems at the site where a vein was taken for heart surgery.

Platelet-rich plasma may improve wound healing by stimulating cell growth and blood vessel formation.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

Lasers in hair transplantation may have potential but require caution due to possible damage and reduced graft survival.

The two-step procedure of fat grafting followed by hair grafting improves scalp and facial scar correction.

Hair restoration surgery techniques can effectively treat scalp deformities and have evolved to provide natural-looking results.

Tissue expansion is a useful method for reconstructive surgery with good results and room for further enhancement.

Hypochlorous acid spray improves wound healing and reduces redness and itching in hair transplant surgery.

Skin cells release substances important for healing and fighting infection, and understanding these could improve skin disorder treatments.

Ruxolitinib helps protect skin stem cells and keeps skin healthy in mice with skin GVHD.

Nitric Oxide has potential in medicine, especially for infections and heart treatments, but its short life and delivery challenges limit its use.

Stem cells and their exosomes show promise for repairing tissues and healing wounds when delivered effectively, but more research is needed on their tracking and optimal use.

Graphene oxide helps deliver a skin healing agent over time, improving skin and hair follicle regeneration.

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

Chemotherapy can cause skin problems like hair loss, mouth sores, and skin darkening, and recognizing these can affect treatment decisions.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Toxic epidermal necrolysis is a severe skin reaction often linked to drugs, requiring careful medication use and supportive care.

Male hormones worsen kidney transplant damage, but blocking them helps.

Modern wound dressings like hydrocolloids, alginates, and hydrogels improve healing and are cost-effective.

Deep Plane Fixation in scalp surgeries allows for more tissue removal with less tension, leading to better healing and less scarring.

Deep Plane Fixation in scalp surgeries allows for more tissue removal with less tension and minimal scarring.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

Human hair follicles produce and respond to erythropoietin, helping protect against stress.
