Scientists created a 3D skin model that shows typical signs of aging, which can help in aging research.

Newborn skin cells can change into wound-healing cells more easily than adult ones, which might explain why baby skin heals without scars. Understanding this could help treat chronic wounds and prevent scarring.

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

Fibroblast Growth Factors (FGFs) are important for tissue repair and regeneration, influencing cell behavior and other factors involved in healing, and are crucial in processes like wound healing, bone repair, and hair growth.

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

Chronic scalp lesions with crusts and pus that heal with strong topical steroids suggest Erosive Pustular Dermatosis, confirmed by biopsy showing specific immune cells.

Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

CXCL12 protein slows down hair growth through its receptor CXCR4. Blocking this can potentially increase hair growth.

Gardenia florida fruit extract may help hair grow and needs more research to understand how.

Fusidic acid can be an effective topical treatment for superficial bacterial infections in dogs.

Mice with a virus similar to COVID-19 had skin damage, but a special treatment helped repair it.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

Artificial dermis used for hair transplantation can reconstruct scalp defects effectively without the need for tissue expansion.

Liposomes could improve how skin care products work but are costly and not very stable.

Nanoparticles effectively deliver water-insoluble drugs to hair follicles, stimulating hair growth without irritating the skin.

Nanoparticles can be used to deliver drugs to hair follicles, potentially improving treatments for conditions like acne and alopecia, and could also be used for vaccine delivery and gene therapy.

Understanding different types of skin cells, especially fibroblasts, can lead to better treatments for wound healing and less scarring.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Niosomes are promising for skin drug delivery, offering benefits like improved drug penetration and stability.

Nanoparticles can enter the skin, potentially causing toxicity, especially in damaged skin.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

Microneedle made of iron oxide and PVA helps hair regrowth in alopecia treatment.

VEGF stimulates hair cell growth and increases growth receptor levels through a specific signaling pathway.

Fat stem cell particles help regrow hair.

Active transdermal technologies in cosmetics help deliver skin treatments effectively, but their safety and effectiveness depend on skin type and treatment choice.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

Platelet-Rich Plasma treatment improved hair growth and reduced inflammation in patients with patchy hair loss, but not in total hair loss, and Optical Coherence Tomography was useful in tracking this progress.

Tattooing improves appearance of scalp alopecia and scars.

Freezing gamma-irradiated amniotic fluid may help hair growth and speed up the growth phase.

Scientists discovered a new way UVB light increases skin pigmentation through the ATP-P2X7 pathway.
