I'm 4A with the longest parts 4 inches.
1. First thing first, you need different roller sizes if your hair is different lenghts, I use the hard rollers that have a cover- pink- large, green- medium, and blue for small.
2. Divide your hair in four sections- use your Denman to stretch the hair and use a clip to keep each part down.
3. Arm yourself with a water bottle and small tooth comb- the black one with the pointy end- you need this to smooth your ends.
4. I don't use setting lotion- it makes my hair dry- I only use a moisturizer like CDHHB on my hair from root to end.
5. Start with the spray bottle- the hair must be completely soaked or you end up with fuzz- spray the hair, grab the small tooth comb, pull hair tight and pull comb through the ends- you don't loose hair believe me!
6. Wrap the hair around the roller- put the cover on and go to the next section of hair. Use small sections of hair.
7. Sit under the dryer for atleast an hour- maybe longer in yours but you can not leave the dryer until the hair is completely dry or again you will have fuzz.
I don't recommend free standing rollers that don't have covers- the purple, gray, red, so on.
