Follicles form hair
Root cause: Follicles need a steady supply of a few nutrients; sudden hair loss needs a doctor.

How this step works · what slows it down · sources
Hair follicles in the skin form hair. Several nutrients are authorised to contribute to the maintenance of normal hair and nails. NIH NIAMSEUR-Lex
“EU claim” items use the exact wording of Reg. (EU) No 432/2012 EUR-Lex; listed foods meet the legal condition of use (amounts per normal portion, BLS 4.0 / USDA).
Authorised claims say a nutrient contributes to a normal body function. They do not mean that eating more than you need improves that function, or that a food treats any condition. Population studies show associations, not proof of cause.
Meal options built from this flow
Pick any option per meal. Ranked by how well one portion covers this goal's targets and how many steps above its foods support (reference adult, everything diet). The planner adapts portions, diet type and allergies.
In short
Zinc and selenium contribute to the maintenance of normal hair and nails; biotin to normal hair; copper to normal hair pigmentation.
