Only if you're deficient — zinc fixes shedding caused by low zinc, but extra zinc doesn't grow hair in people with normal levels.
Zinc is essential for the hair-growth cycle, and a genuine deficiency can cause hair loss that resolves once corrected. But most people who eat a normal diet aren't deficient, and there's no good evidence that taking extra zinc beyond your needs grows more hair. Worse, chronic high-dose zinc can cause copper deficiency and its own type of hair loss.
Bottom line: don't supplement zinc blindly for hair. If you have risk factors (restrictive diet, gut conditions) or unexplained shedding, ask for a blood test and correct a real deficiency. Otherwise, focus on proven treatments and a balanced diet rather than guessing with high-dose minerals.

FAQ
Can low zinc cause hair loss?
Yes — a true zinc deficiency can cause shedding that improves when levels are restored. But this is uncommon in people eating a varied diet, and testing is better than guessing.
How much zinc is safe?
Staying near the recommended daily intake is safe; chronic high doses (well above it) can cause copper deficiency and even hair loss. Don't megadose zinc without a confirmed need and medical advice.
