Do you mean breakage (short bits and pieces of hair)? Your hair is probably overprocessed then. You should do an Aphogee treatment immediately. Are you familiar with this product? It's a heavy duty protein treatment that stops the damaging effects of chemical overprocessing.
You should purchase the following (Sally's has it):
(The first three products sometimes are purchased in a kit. Buy the kit, if you have the option, instead of individual bottles.)
--Aphogee Shampoo

--Aphogee Treatment for Damaged Hair

--Aphogee Balancing Moisturizer
http://www.sallybeauty.com/shop/product.asp?pf%5Fid=670505&dept%5Fid=1215
--Also have a good deep conditioning moisturizer
You will need to follow the directions precisely though (and I mean precisely). Warning: Your hair will get extremely hard. Do not under any circumstances manipulate, touch or comb your hair at the hardening stage. Leave it alone.
After you complete the three step Aphogee treatment, follow up with a deep conditioner for 20-30 minutes under a hooded dryer.
Some other members have had good success using their own shampoo (instead of Aphogee's and skipping the Balancing Moisturizer and just going straight to the deep conditioner). Do a search on this board for "Aphogee." I will try to bump you if I find a thread. Let us know how you are doing.
P.S. In the future, don't let the perm sit on your head for more than 20-22 minutes.
