Silk & your hair.
Watching your hairline? Your hat sits right on it for hours a day, and most are lined with cotton that grips, rubs and dries out the hair there.
Your hairline takes the most wear of any hair on your head, and a hat band sits right on it. Every time your hat shifts, cotton grips those fine hairs. Wear it daily and that friction shows up as dryness, frizz and breakage.
What changes.
Rough fibers grip the hair shaft and pull with every movement.
Grade 6A mulberry silk. The band glides over hair instead of gripping it.
Repeated friction frays and breaks strands at the hairline.
Less friction means less breakage where your hat sits.
Soaks up your scalp’s natural oils, drying hair out.
Leaves natural oils in place, keeping hair balanced.

Hats and your hair, answered.
Can wearing a hat cause hair loss?
Research hasn’t shown that hats cause pattern hair loss. What a hat can do, worn every day, is add friction, pressure and heat right at your hairline, which can lead to breakage and stress on the hair there. If you’re noticing thinning, see a dermatologist, and in the meantime choose a hat that isn’t tight and has a smooth lining.
Does wearing a hat every day damage your hair?
It can. A rough cotton band grips and frays the hair shaft each time your hat shifts, and cotton soaks up the natural oils that keep hair soft. Over time that shows up as dryness, frizz and breakage.
Why is Hatsy Silk-Tech™ gentler on your hair?
Hatsy Silk-Tech™ glides instead of gripping, so there’s far less friction on each strand, and it leaves your hair’s natural oils in place. It’s the same reason people sleep on silk pillowcases.
Is it OK to wear a hat if my hair is thinning?
Yes. Just avoid hats that are tight or have rough bands. A Hatsy has an adjustable silk strap and a silk band, so there’s less pressure and friction at the hairline.
How does a Hatsy fit?
Every Hatsy is one size with an adjustable silk strap at the back, so it fits most heads. The brim is pre-curved (7cm). If the fit isn’t right, you have 30 days to return it.
How do I wash my Hatsy?
Hand wash cold and let it air dry. Washing your hat regularly matters for any hat, since sweat and oil build up in the band over time.
