A balanced diet with enough protein, iron and other nutrients supports normal hair growth, but no single food or supplement regrows pattern hair loss. Mega-doses of supplements can even harm, so test for deficiencies with a doctor and focus on regular, varied meals.
Myth: biotin fixes everything
Biotin helps only if you are deficient, which is uncommon; high doses can also affect some lab tests.
Myth: more protein is always better
You need enough, not extreme amounts. Crash diets are a common cause of shedding.
What helps
Regular meals, protein at each meal, iron-rich foods, fruit and vegetables, and checking with a doctor if you diet strictly.
Questions
Should I take a hair supplement?
Only to fix a known gap; ask a doctor or pharmacist.
Can crash diets cause hair loss?
Yes, rapid weight loss can trigger shedding a few months later.
