I have two pieces of these hair bands get paid and am very happy with it, because they keep my very thick, naturally curly hair well or not at all slip. In this respect, I would buy more which, should it become necessary - the parts so far are very durable and hardly worn, moreover, I have the other reviews here are taken from the tip to put the gum in hot water - and actually pull thereby again all together! The only drawbacks I see the one in the name of the product, which led me to the false expectation that they could not see when wearing hair bands - That's not - and secondly the gums are not comfortable lying down.
