Plant-based chemicals may help hair growth and prevent hair loss but need more research to compete with current treatments.

The document concludes that permanent hair loss conditions are complex, require early specific treatments, and "secondary permanent alopecias" might be a more accurate term than "secondary cicatricial alopecia."

Androgen receptor signaling causes early aging of cells important for hair growth by damaging their DNA.

Cryopreserved mouse whisker follicles can grow hair when transplanted into nude mice.

Adult mouse skin contains stem cells that can create new hair, skin, and oil glands.

Hair follicle stem cells are controlled by their surrounding environment.

Androgenetic alopecia involves genetics, hormones, and can be treated with medications or surgery.

SDF-1/CXCL12 and its receptor CXCR4 are crucial for melanocyte movement in mouse hair follicles.

Special particles from skin cells can promote hair growth by activating a specific growth signal.

The review concluded that keeping the hair-growing ability of human dermal papilla cells is key for hair development and growth.

Platelet-rich plasma (PRP) may help with various hair loss types, but more research is needed to find the best use method.

The study concluded that similar pathways regulate hair growth in dogs and mice, and these pathways are disrupted in dogs with Alopecia X, affecting stem cells and hormone metabolism.

Best solution for storing hair grafts is saline with ATP at 4 degrees Celsius, but no definitive best method was confirmed.

Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.

Skin stem cells can help improve skin repair and regeneration.

VEGF helps squamous cell carcinoma grow in ways beyond just blood vessel formation.

Nanoencapsulated antibiotics are more effective in treating hair follicle infections than free antibiotics.

Nanocarriers with plant extracts show promise for safe and effective hair growth treatment.

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

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.

Advancements in tissue engineering show promise for hair follicle regeneration to treat hair loss.

Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.

New methods to test hair growth treatments have been developed.

Stem cells, especially from fat tissue and Wharton's jelly, can potentially regenerate hair follicles and treat hair loss, but more research is needed to perfect the treatment.

Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Human dermal fibroblasts help microvascular endothelial cells grow, but not vice versa.

Platelet-rich plasma (PRP) is effective in treating various skin conditions and improving hair density, thickness, and patient satisfaction, with lower relapse rates for Alopecia Areata.

Keratin from hair and wool is used in medical materials for healing and drug delivery.
