Researchers developed a model that shows hair follicles increase skin absorption of caffeine by 20%.

Researchers created a skin treatment that could effectively deliver medication into hair follicles.

Boosting β-catenin signaling in certain skin cells can enhance hair growth.

A patch made from human lung fibroblast material helps heal skin wounds effectively, including diabetic ulcers.

Myristoleic acid helps hair growth by boosting cell growth and recycling processes in hair follicle cells.

Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.

Different body areas in mice produce different hair types due to interactions between skin layers.

Different types of sun exposure damage skin cells and immune cells, with chronic exposure leading to more severe and lasting damage.

Proretinal nanoparticles are a safe and effective way to deliver retinal to the skin.

Certain fats in the skin help control inflammation and health, and changing these fats through diet or supplements might treat skin inflammation.

Tridax procumbens plant extracts, especially from ethanol, have strong antibacterial effects and contain beneficial compounds like flavonoids and tannins.

Menopause can lead to skin and hair problems due to hormonal changes, but hormone replacement therapy might help slow these effects.

Skin surface lipids are important for skin health and altering them could help prevent aging and treat skin conditions.

Dermatologists should customize cosmetic treatments for dark-skinned patients to minimize risks and complications.

Fullerenes show potential in skin care but need more safety research.

Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

The document concludes that low-dose acne treatment is most suitable for moderate acne, with high patient satisfaction and low relapse rates.

Aging skin is affected by inflammation, reduced stem cell function, and slower wound healing.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Bone marrow-derived stem cells improved healing and reduced scarring in second-degree burns in rats.

Cell-based models help test if cosmetic ingredients really work for hair growth and skin health.

Tissue engineering could be a future solution for hair loss, but it's currently expensive, complex, and hard to apply in real-world treatments.

Hyaluronate fragments can help reverse skin thinning by working with the CD44 receptor.

A new hydrogel made from human cells improves wound healing by working with immune cells to promote repair.

Buffalo flies and Stephanofilaria nematodes cause severe skin lesions in beef cattle, and treatment should target both.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

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.

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

Male and female skin differ due to hormones, affecting conditions like hair loss, acne, and skin cancer, and suggesting a need for gender-specific treatments.

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