not good for thick hair definitely not made for curly hair [SEP] in theory these should be great but the truth is they are not made very well i cannot say i am shocked given the price was less than for of them definitely not for thick hair and questionable for most adult hair the main issue is that the closure does not have enough of a knotted area to be very effective on staying closed so if you are wanting for younger girls or adults with very fine hair they are possibly worth getting the colors are the thing that will make it worth the purchase
