I love, love, love these things. I was at Target about nine months ago and I bought a pack of the black Scunchi No Slip Grip headbands and as an introductory sample one Evolution Band came included in the back. Initially didn’t know what to do with it, so it sat for a couple of months unused. While during that time I was going through the black bands like water. They were always getting stretched out from my puffs and were never tight enough to wear as a regular headband even brand new. So, I decided to give that weird little rubber thing a try, and can I say pure awesomeness! :-) The Evolution headband almost feels like some type of rubbery gel and it’s very elastic and held it shape for months and months of continuous use. This is the only bands that I use in my hair, they’re super stretchy, soft, they don’t snag or snarl my hair, and I can wipe them clean from my hair products. As long as Scunci keeps making them, I’m going to keep buying them. I even have a small stock pile started just in case to give me peace of mind. Scunci No Slip Grip Evolution Headbands are awesome!
