Review title is OUCH! [SEP] [[ASIN:B072HH2J8X Healthcom 24 Pack Hair Styling Twist-flex Rods Flexible Curling Rods Hair Rollers for Girls and Women]] OUCH! Tried these one evening and I was unable to sleep on my side....just too hard and uncomfortable. Taking them out was a nightmare! The velcro tangled my hair and it was difficult to remove. As far as using a hairdryer...wouldn't they melt?
