Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

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.

Muscles and nerves that cause goosebumps also help control hair growth.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Thyroid function affects skin health, with a complex interaction between the two.

Different lasers and radiofrequency affect skin differently, important for dermatologists to choose the right treatment.

DNA methylation and long non-coding RNAs are key in controlling hair growth in Cashmere goats.

Scientists have made progress in growing mini-organs and regenerating parts of the skin, with plans to treat hair loss in a future trial.
