Hair elemental analysis could be useful for health and exposure assessment but requires more standardization and research.

The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.

Ancient Chinese goats evolved cashmere-producing traits due to selective breeding, particularly in genes affecting hair growth.

The study developed a method to analyze ancient hair proteins using very small samples.

Sardinians were historically short due to a mix of genetics and factors like disease and poor nutrition, but recent height increases suggest better living conditions had a bigger impact.

Dates may improve heart health, fight infections, protect kidneys, reduce inflammation, support pregnancy, promote dental and bone health, enhance mental function, and have anti-cancer properties, and are also beneficial for skin and hair care.

Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.

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

Humans lost body hair relatively recently in evolution.
