The Nano Tough was built specifically for women who have very thin or delicate hair - breaks under any tension.
These Strongbands™️ are the perfect example of mini but mighty! Your hair is thin but that doesn't mean you don't need it out of your face to get stuff done. This size can also be perfect for hairstyles like half ponytails, or at the ends of your braids if your hair is super thick.
They provide optimal hold for a ponytail diameter of 2.5 inches or less. For more information on sizing, check out "What Size Should I Get"
