i have very fine straight hair [SEP] i have had this for about months and it has less than half the bristles left i have very fine straight hair so it is not like i tortured it with difficult hair and expected it to last forever i remember losing a quarter of the bristles by months or so if you do not mind buying a new one every to months then by all means buy this one i however am investing more in a better one that hopefully lasts at least a year
