The Multi-Organ-Chip improves the growth and quality of skin and hair in the lab, potentially replacing animal testing.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Researchers created human hair follicles using a new method that could help treat hair loss.

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

Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.

Pig skin is a good substitute for human skin to measure drug absorption, but differences in skin structure and enzymes across species must be considered.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

The document recommends using both clinical evaluation and various measurement methods to assess skin greasiness, considering factors like temperature and hormones.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Microneedles help improve skin appearance and deliver skin treatments effectively, but safety concerns need more research and regulation.

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.

Aromatherapy with certain essential oils is a safe and effective treatment for hair growth in alopecia areata patients.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

Ethosomes improve finasteride delivery through skin for hair loss treatment.

Nearly half of the French individuals surveyed reported having a sensitive scalp, more common in women, often linked to hair loss and symptoms like itching, and triggered by factors including shampoos and pollution.

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

The nude gene causes skin cell overgrowth and improper development, leading to hair and urinary issues.

Mice with human skin protein K8 had more skin problems and cancer.

A 3-month stay in space causes skin thinning, disrupts hair growth, and changes muscle-related genes in mice.

Improved hair loss treatment using special particles and surfactants.

People with atopic dermatitis are more likely to develop other skin conditions due to shared genetics and immune pathways.

Eph/ephrin signaling is important for skin cell behavior and could be targeted to treat skin diseases.

A special hydrogel helps heal skin without scars and regrows hair.

Engineered skin substitutes can grow hair but have limitations like missing sebaceous glands and hair not breaking through the skin naturally.

Finasteride slightly better long-term, minoxidil faster initial results, but stopping minoxidil may cause hair loss.

The conclusion is that measuring how drugs partition into artificial sebum is important for predicting their delivery into hair and sebaceous follicles, and it provides better information than traditional methods.

Excipients greatly affect how well curcumin nanocrystals penetrate the skin and target hair follicles.

Using a special laser can improve how well hair loss treatments get into the skin and hair follicles.

Stress in mice delays hair growth and treatments blocking substance P can partly reverse this effect.

15-lipoxygenase helps keep skin healthy by reducing inflammation.
