Smilco4 Pack Shower Caps, Double Waterproof Layers Reusable Bath Caps for Women Hair Protection

Q: Can this product be used under a heat cap?

Dear buyer: Our shower cap can be used under a heat cap, but we don't recommend it because it's made of EVA that changes shape when the temperature reaches 80°C or 176°F!

Q: How big are they? Is it a Good size for a very long hair?

Dear Buyer. The size of this shower cap is 12.6 inches in diameter on the outer ring and 5.3 inches on the inner ring (the inner ring is designed with an elastic band). How long it fits depends on the density of your hair!

Q: Do they have to be washed in washing machine to be cleaned between uses?

I do not clean each time I wear the shower cap. It is substantial enough to accommodate long hair. I’ve not washed mine yet but would probably put in a laundry bag and then air dry. Very nice shower cap.
