Researchers found a genetic region that influences the number of coat layers in dogs.

Hair transplantation effectively treats scalp scars with high success and patient satisfaction.

Corrective hair repair surgery can significantly improve appearance and quality of life for patients with unsatisfactory results from old hair transplants.

Both Follicular Unit Transplantation (FUT) and Follicular Unit Excision (FUE) are effective hair transplant methods; the best choice depends on the patient's needs and the surgeon's preference.

Hair transplants are mostly safe but can have minor complications.

Angora goat hair grows faster and produces more protein than cashmere goat hair, and certain hormones and nutrients positively affect hair growth and protein synthesis.

A hair restoration technique was introduced that mixes different types of hair groupings to reduce procedure time, limit damage, and potentially increase hair density, suggesting more hair can be transplanted than previously thought.

Dermoscopy shows that diffuse alopecia areata progresses through specific hair growth stages.

Beard hair transplantation is generally satisfying, requires 250-800 grafts, uses FUE to avoid scars, needs careful planning, has some risks, and hair regrowth starts after 4-6 months.

Using an epidural needle in hair restoration surgery can reduce grafts popping out, make the procedure easier, and result in natural-looking hairlines without obvious scarring.

Gray hair can potentially be reversed, leading to new treatments.

Umbilical cord-derived media is safe and effective for hair growth.

Fat under the skin can help hair grow longer, darker, and increase cell growth.

Chemotherapy and radiation therapy cause skin and hair damage by altering gene expression and signaling pathways.

Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.

Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.

Electric current quickly reduces hand sweating but the effect doesn't last long.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Integrin alphavbeta6 is important for wound healing and hair growth, and blocking it may improve these processes.

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

Noggin is necessary to start the hair growth phase in skin after birth.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.

The EpiLight Hair Removal System removed about 60% of hair with some side effects, and more research is needed to confirm long-term effectiveness.

Light can turn on hair growth cells through a nerve path starting in the eyes.

Different methods of preparing Platelet-Rich Plasma (PRP) can affect wound healing and hair regrowth in plastic surgery. Using a kit with specific standards helps isolate PRP that meets quality criteria. Non-Activated PRP and Activated PRP have varying effects depending on the tissue and condition treated. For hair regrowth, Non-Activated PRP increased hair density more than Activated PRP. Both treatments improved various aspects of scalp health.

Activating Nrf2 protects human hair follicles from oxidative stress and helps prevent hair growth inhibition.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.

Minoxidil may help hair growth after transplant surgery.

Pulsed-intense light can significantly reduce hair, with effectiveness depending on treatment number and timing, and has mild side effects.
