I think it helps to do these three things:
1. Avoid the use of too much heat, (flat irons, pressing combs, hot curlers.)
2. Wear hair in styles that do not require excessive manipulation and/or are not too tight on your hair.
3. A wide-tooth comb is a must, and a good detangling conditioner is another must.
Maybe you should stop handling your hair every day. Could you wash/condition/detangle once a week or every five days instead of every day?
