My hair is long, thin, layered, straight, dry and color treated. I try to keep heat styling to a minimum but I can't just wash and go either. Hot rollers don't hold a curl in my hair. Velcro rollers work ok but I can't sleep in them. I bought 2 sets of these foam rollers several years ago so but I didn't use them often. I don't know why I stopped because they are great. Probably because I thought the next curling iron or set of hot rollers would be better.
The best thing about them is you can easily vary the type of curl you get. You can also use a setting spray if you want. Using them on very damp hair and sleeping in them will produce the tightest curl. Using many rollers and and wrapping small sections of twisted hair tightly will produce springy coils. Using them on nearly dry hair, wrapping larger sections of hair more loosely and sleeping in them will give you big, loose curls. The curl really lasts too, even in my very difficult to curl hair.
The rollers don't take long to put, just wrap & twist, in but I don't think they'd be very effective without leaving them in overnight. The downside is they obviously don't work as quickly as heat styling appliances. The other short fall I see is that the cushion part of the roller is fairly short which I compensate for by just using more rollers. They produce curls, not volume so I often set the top of my hair in large velcro rollers. They are very comfortable to sleep in and easy to remove. I bought mine at Walgreens and I just saw them on sale, $6 for a set of 18. Sometimes, old school works better. It may take some experimenting to find out what works in your hair but I definitely think these are worth a try if you have the time. continued >>
