“This is the first hat I’ve ever seen that is genuinely better for your hair and skin. The silk lining isn’t a gimmick, it’s the same principle I tell every patient who asks how to protect their hair while living their life.”

Why It Works
The Hat Built For Your Hair, Skin & Comfort.
01
Prevents Hair Loss Caused By Hats
Daily hat-wearing creates friction at the hairline. Over time that friction causes breakage and thinning. Real silk eliminates that friction. Your hair grows where it’s supposed to.
02
Clears Hat-Related Acne
Cotton traps heat and bacteria against your scalp and forehead. Silk is naturally breathable and antimicrobial. No more breakouts at the brim. No more hat-line acne.
03
All-Day Comfort
Silk regulates temperature better than any synthetic material. Cool when it’s warm. Not scratchy. Not tight. You forget you’re wearing a hat — which is exactly the point.
04
Doctor Developed
Co-developed with Dr. Robert Dorfman — Beverly Hills hair restoration surgeon, Oxford and Northwestern trained. The first hat clinically designed to protect both hair and skin.
