Superdrug 10 pk Black 3.5mm Silicone Bands

genuinely do hold hair without slipping. not the cheapest but work out at more reasonable price when bought, as I did, buy 1 and get 1 half price

Good hold, indeed non slip! But need to be careful when taken it off or it will pull off a few hair. But the hold is the best hair band I have ever used. Great for sports! My mum and friends abroad tried them and loved them, so I have bought many packs...
