Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

The new assay can track and measure melanosome transfer between skin cells, confirming filopodia's role in this process.

Scientists successfully created and transplanted bioengineered hair follicles that function like natural ones, suggesting a new treatment for hair loss.

The hair follicle is a great model for research to improve hair growth treatments.

Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.

The gene Foxq1, controlled by Hoxc13, is crucial for hair follicle differentiation.

Blocking BMP signaling causes hair loss and disrupts hair growth cycles.
