Traction alopecia is more common in African women than girls, especially when traction is applied to chemically relaxed hair; avoiding such hairstyles may reduce the risk.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

Prolactin slows down hair growth in mice.

Hair problems can be caused by genetics or the environment, and treatment should focus on the cause and reducing hair damage.

STAT5 activation is crucial for starting the hair growth phase.

The article concludes that developing in vitro models for human hair structures is important for research and reducing animal testing, but there are challenges like obtaining suitable samples and the models' limitations.

Different processes create patterns in skin and things like hair and feathers.

Cat color patterns are determined early in development by gene expression and epidermal changes, with the Dickkopf 4 gene playing a crucial role.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Fine wool sheep have more genes for wool quality, while coarse wool sheep have more for skin and muscle traits.

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.
