Shampooing your Hair Every other Day

So after reading some Yahoo Questions I have decided to try Shampooing my hair every other day. My hair has a mind of its I own I swear it it typically very dry or very greasy never in between! So I tried the first day as usual with shampooing my hair had some frizz. The next day I only conditioned ( i was using my ovation cell therapy bottle). My hair that day smelled really nice and was very soft. I did do a bad mistake and decided to straighten my hair with the added protective heat spray I used it made my hair look really greasy. Ick. The next day I washed my hair and it is looking good! I did not straighten or blow dry my hair. I think this may have helped. I plan to try this throughout the week and let you know what worked. I think this formula has to be different for every person and their hair. I definitely say though going with out shampoo for dry frizzy hair is a Must!
