Scientists can control how skin stem cells divide by using different treatments.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Wounds heal without scarring in early development but later result in scars, and studying Wnt signaling could help control scarring.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

Steroid sex hormones activate matriptase in prostate cancer cells but not in breast cancer cells.

A woman developed male traits from accidental contact with her husband's testosterone gel.

Fetal skin has unique immune cells different from adult skin.

Careful planning and technique in upper facial rejuvenation can minimize risks like hair loss, nerve damage, and scarring.

Secondary amenorrhea has many causes and requires thorough evaluation to treat and restore menstrual cycles.

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Injectable platelet-rich fibrin improves hair growth and reduces hair loss in women.

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.

Western diet may cause male pattern baldness; low glycemic diet with magnesium could help.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

Certain gene variations in the Vitamin D receptor may increase the risk of chronic hair loss.

A patient with myotonic dystrophy had several autoimmune disorders and thyroid cancer, suggesting a possible link between these conditions.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Telogen Effluvium is a common hair loss condition that can be short-term or long-lasting and is often caused by stress, illness, or nutritional issues.

PRP helps skin heal, possibly through special cells called telocytes.

Targeting a protein that blocks hair growth with microRNAs could lead to new hair loss treatments, but more research is needed.

Hair transplants onto a scalp reconstruction flap improved appearance successfully.

The article explains how to rebuild parts of the head and face and how to transplant hair to cover scars, highlighting the need for careful planning and choosing the right method for each patient.

The article concludes that microvascular free flaps, especially the latissimus dorsi flap, are recommended for large scalp reconstructions, and hair transplantation offers high survival rates and excellent aesthetic results.

Understanding the scalp's five-layer structure is crucial for better surgical outcomes and fewer complications.
