Comb through damp hair to work out tangles. Your hair shouldn't be sopping, just damp.
Apply setting lotion or setting mousse to your entire head, working it through with the comb for full and even coverage.
Begin at the back of the head and part off a section no wider or thicker than 1 inch. Place the roller under the end of your hair and roll it under until it's touching your scalp. Keep your tension even so that your hair stays straight and smooth.
Secure the roller and move on to the next section of hair. Repeat over your entire head, tucking in the ends to prevent frizz.
For loose waves, use jumbo magnetic rollers. The smaller the rollers, the tighter the curl.
Direct rollers to the back of your head so that your hair falls away from your face.
Wait until your hair is completely dry before removing rollers.
Don't use big chunks of hair to make setting go more quickly. Your hair will take longer to dry and won't be smooth.
