Before getting started, wash your hair two times with a clarifying shampoo to get rid of any residue from dirt or styling products.
Pull all of your hair back into a low ponytail, but leave the top section free. Comb the free section out until it is nice and smooth.
Part the hair on the top of your head into five smaller sections running from your forehead to the back.
Now it's time to wrap the sections around your perming rods. Hold out one of the small sections and place the rod behind the hair so that it is flush against your head.
Wind the hair around the rod one or two times, depending on the length of your own roots. Secure the hair into place. Your hair may look funny since there will be a bit of a tail left over while the rod is in your hair, but that's because you are only perming the roots and not your whole head.
Repeat Steps 4 and 5 until the entire top of your head is in rollers. Divide the rest of your head into four more sections (two sides, the middle of the back and the bottom back) then do the same for the rest of your head.
Follow the guidelines on your at-home perm kit when applying the perm mixture -- different kits have different directions so make sure to follow them closely.
