Dirty hair is gross. But cmon, honestly I hate showering everyday. Don't get me wrong, I love the feeling of 'getting right out of the shower' clean. But I hate that it takes me literally over an hour just to get ready. The majority of the time definitely goes towards air drying my hair, b/c it gets so frizzy and dry if I run the blow dryer through it.
Anyway, so what I like to do is wash my hair every other day. I'm in the process of 'training it' to be able to adapt to the change. I concluded that since I wash it everyday, and with it being all frizzed out nasty....it just gets dry. So my body compensates for the oil depletion by producing even more oils to keep my hair nicely conditioned and anti-dandruffy. Makes sense? So maybe if I stop showering on the daily, maybe once every other day (2-3 days is PUSHING the questions towards maintaining good hygiene, of mine & others haha) so that my body would sense that it does not need to produce as much oils. Hence making me have more free time to sleep, and saving more water and shampoo. :)
In the meantime, I've google'd up on some dry shampoos. Which comes in a hairspray can, and you just spray it into your roots and I'm assuming that it kinda sprays a powder or drying agent to soak up your natural oils. I haven't tried it yet, but I think I might give it a try.
Also, another thing to mention....the difference between expensive salon shampoos/conditioners from your local drugstore's shampoo is that there is more water in the salon ones. So I guess it's a more mild and gentle formula on your hair than harsh shampoo'ing and stripping your tresses of natural oils.
