Review title is I took a chance, but again, I was wrong [SEP] See, I have naturally curly hair.  The issue is when the weather is very dry over a few days' time, my hair goes flat.  Curly hair curls a LOT in humid weather; hence, the frizz which we deal with!  Anyway, I saw these and thought that maybe during those really dry winter days these would assist me in getting my hair to curl as it should.  Now, the problem is, curly hair "fights" with some hair items - from my younger years my sisters used bristle curlers (they had straight hair) but the first time I tried using them, my hair like BIT INTO those bristles and man, I nearly had to cut my hair off to get those demon curlers out of my hair!  These are similar, apparently to the bristle, demon curlers as they grabbed a hold of my wet hair and when I tried to pull one off, even holding onto the hair at my scalp, I could feel the tube holding onto my hair for dear life.  That was with WET hair...I'm glad I did not wait for my hair to dry before attempting to pull the tube off!  I have several friends with longer, straight hair and I'm sure they will have a different, happier and more comfortable experience than I did.  What I'm saying is that I'm sure they work - for those with straight hair.  If you have curly hair, best be careful when using them!
