Masculine facial features may not reliably indicate heritable health, and more research is needed.

Horizontally sectioned scalp biopsies are more reliable for diagnosing hair loss in women when three samples are taken instead of one.

PRP treatment improves hair growth, and the device used can affect results, with some being more effective.

Turmeric may have benefits for skin health, but more research is needed to confirm its effectiveness.

Different types of stem cells and their environments are key to skin repair and maintenance.

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.

Over one-third of women experience hair loss, with female-pattern hair loss being most common, and treatments include minoxidil and possibly hair transplantation.

The conclusion is that the risk of losing significance in meta-analysis results increases with smaller effects and more missing data, and using the median standard deviation for imputation is recommended.
