Researchers created a rat model to study skin damage caused by radiation, which could help develop new treatments.

Injecting scalp tissue micrografts is a safe and effective treatment for hair loss after COVID-19.

New therapies are being developed that target integrin pathways to treat various diseases.

Hair follicles are normally protected from the immune system, but when this protection fails, it can cause hair loss in alopecia areata.

Smoking increases early hair loss risk in men; quitting may help prevent it.

Adding platelet-rich plasma improves hair density and thickness in androgenetic alopecia.

Both methods improve hair density and thickness; double-spin may be more effective.

BeauTop improves hair growth in androgenetic alopecia patients.

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

Platelet-rich plasma (PRP) may improve healing in chronic wounds and vitiligo and promote hair regrowth, but more research is needed.

Leptin, a hormone from fat cells, affects immune responses and can influence skin diseases and hair growth.

Broussonetia papyrifera extract helps hair growth by regulating specific proteins.

The Chinese herbal supplement BeauTop can potentially boost hair growth and thickness by increasing a protein called Vascular Endothelial Growth Factor.

3D bioprinting improves wound healing by precisely creating scaffolds with living cells and biomaterials, but faces challenges like resolution and speed.

Hyaluronic acid injections can improve mouth opening and quality of life in scleroderma patients.

A new method using Platelet-rich Plasma (PRP) in a microneedle can promote hair regrowth more efficiently and is painless, minimally invasive, and affordable.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

In September 2016, there were major advancements and promising clinical trials in stem cell research and regenerative medicine.

The study found that stem cells and neutrophils are important for regenerating hair follicle structures in mice.

Scientists identified a unique type of human skin stem cell that could help with tissue repair.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

The new skin patch with human matrix and antibiotic improves wound healing.

Autologous Platelet and Extracellular Vesicle-Rich Plasma (PVRP) has potential in enhancing tissue regeneration and improving hair conditions, but its effectiveness varies due to individual differences.

Modified rat stem cells on a special scaffold improved blood vessel formation and wound healing in skin substitutes.

WNT signaling is crucial for skin development and healing.

Hair aging is caused by stress, hormones, inflammation, and DNA damage affecting hair growth and color.

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

Old drugs like finasteride and spironolactone are being successfully used for hair loss and skin conditions, and many other drugs show promise for new uses in dermatology.

Combining microneedling with platelet-rich plasma enhances skin repair and collagen production but may not offer significant extra benefits.
