You can do a few things do reduce hair breakage:
1) When you get out of the shower, blot your hair with your towel instead of rubbing vigorously. This will reduce the friction on your delicate hair.
2) Use a wide toothed comb to get knots out, and be gentle. A spritz of leave-in conditioner on the ends will help you work the comb through tangled areas. "Infusium" is by far the best.
1) If you blowdry your hair, make sure that you don't do so while its soaking wet, when hair is at its weakest. The tension from your hairbrush combined with heat damage from the hairdryer can cause your hair to snap. Give your hair a 15-minute "pre-dry", you can do your makeup or grab some breakfast while you wait.
3) Be gentle with your hair if you do blowdry and take a few extra moments to make certain you are not over-pulling your hair as you style. As your hair dries, it begins to gain back its tensile strength, so baby it while its wet.
4) If you like pulling your hair back in tight ponytails or other constricted styles, you may want to stop (or at least give your hair a few days rest in between). The constant tension on the hair can cause it to weaken and eventually break off.
5) Use a good, intense conditioner at least once a week to help strengthen any damaged areas.
6) Since beauty always comes from within, make sure you are feeding yourself right. Do a search on the Internet for foods that help aid with hair strength. I have been taking Flax Oil for the past 6 months and my hair has never been stronger (Flax oil is an excellent source of Omega-3 fatty acids, which are essential for shiny, strong hair).
Hope this helps!
