Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

Different immune cells like platelets, mast cells, neutrophils, macrophages, T cells, B cells, and innate lymphoid cells all play roles in skin wound healing, but more research is needed due to inconsistent results and the complex nature of the immune response.

Hedgehog signaling in certain cells is crucial for hair growth during wound healing.

Regulatory T cells help heal skin and grow hair, and their absence can lead to healing issues and hair loss.

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.

Obesity can worsen wound healing by negatively affecting the function of stem cells in fat tissue.

Cannabinoids like CBD and THC may help treat non-cancer skin diseases, but more research is needed.

Ultrasound can help deliver genes to cells to stimulate tissue regeneration and enhance hair growth, but more research is needed to perfect the method.

Scientists turned mouse skin cells into hair-inducing cells using chemicals, which could help treat hair loss.

Nanostructured delivery systems could potentially improve hair loss treatment by targeting drugs to hair follicles, reducing side effects and dosage, but the best size, charge, and materials for these systems need further investigation.

WNT signaling is crucial for skin development and healing.

Autophagy helps control skin inflammation and cancer responses and regulates hair growth by affecting stem cell activity.

Nanofiber scaffolds help wounds heal by delivering drugs directly to the injury site.

Plumbagin may help protect cells, reduce inflammation, and has potential for treating various diseases, but more research is needed.

T-regulatory cells are important for skin health and can affect hair growth and reduce skin inflammation.

Stem cells from hair follicles in a special gel show strong potential for bone regeneration.

Bacterial cellulose is a promising material for biomedical uses but needs improvements in antimicrobial properties and degradation rate.

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

Raccoon dogs in Schleswig-Holstein, Germany, were found with sarcoptic mange, showing severe skin issues and potential for spreading the disease.

Sponges made of soy protein and β-chitin with human cells from hair or fat can speed up healing of chronic wounds.

Removing Mediator 1 from certain mouse cells causes teeth to grow hair instead of enamel.

PBMCsec can help reduce and improve thick skin scars.

A new hydrogel with micronized amnion helps achieve better, scar-free skin healing.

Melatonin, the sleep hormone, can help treat skin conditions like dermatitis, hyperpigmentation, and scalp disorders, and may also aid in skin aging prevention and regeneration. However, it's not recommended for asthma due to its pro-inflammatory effect.

The new microwell device helps grow more hair stem cells that can regenerate hair.

The black orchid Brasiliorchis schunkeana produces chemicals that attract certain insects and have potential antimicrobial properties.

Cinnamon may help manage obesity and improve conditions related to Polycystic Ovary Syndrome (PCOS).

Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.

Using minoxidil for hair loss might cause sudden vision loss, so use it with caution and monitor closely.

Researchers successfully grew horse skin cells that produce pigment from hair follicle samples.
