To secure our reusable, organic face masks, tie them tightly with the two straps behind your head. The mask should fit snugly against your face. To prevent slipping over time, tie your upper ties tight and at the crown of your head — this is especially important if you have thin or fine hair. For those with thicker hair, the straps should stay firmly in place. Wearing a hat will also help create some friction to keep the straps from slipping. If you wear your hair in a ponytail or bun, tie the upper straps above it (see photo). Still having slippage? Try using bobby pins or clips.
