what kind of rollers do you use and how small were they?magnetic rollers are really good. and make sure you get the hair ends wet enough that they 'stick' to the roller, and that they are wrapped smoothly around it. it could possibly be the oil that you put on there that made it do this though. when i used to do my rollersets, i used watered down leave in conditioner (motions is good , elasta qp is too) to keep my hair wet while i rollersetted. then i experimented with foam setting lotions ( dudleys,motions foam wrap) they work well if you are trying to have firmer curls with hold. i dont recall ever putting oil on there until afterward my style was finished. i always seem to think of oil like cooking grease. once that heat hits it, it heats it up and it 'cooks' whatever its on. try not to use too much oil when applying heat . i mean, of course, everyones hair is different, so different results. but if you keep experiencing the same thing, that could be the culprit
