Hårtap og tilskudd: Det ingen forteller deg

Biotin for håret. Vitamin D for hårtap. Selen for “sterkere hår”.

Men hva sier egentlig forskningen?

Og kan noen tilskudd gjøre hårtap verre?

I denne episoden går jeg gjennom tre av de vanligste tilskuddene folk tar mot hårtap, og hvorfor mer ikke alltid er bedre.

Jeg snakker om dokumenterte mangler, overdosering, feilbruk av kosttilskudd, og hvem som egentlig trenger disse tilskuddene.

Hvis du noen gang har vurdert “hair gummies”, TikTok-anbefalinger eller dyre hårtilskudd: hør denne episoden først.
