5% minoxidil works better for hair growth and density, with minor irritation.

Zinc oxide nanoparticles in sunscreen do not penetrate deep into the skin.

Mutations in the SRD5A3 gene cause a new type of glycosylation disorder by blocking the production of a molecule necessary for protein glycosylation.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Cells from balding scalps have more androgen receptors than cells from non-balding scalps.

Some patients taking finasteride or dutasteride may have ongoing sexual problems and depression even after stopping the medication.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.

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

Lecithin organogels could be good for applying drugs to the skin because they are stable, safe, and can improve drug absorption.
