Wash your body and hair with olive oil soap (very affordable from greekinternetmarket dot com) and rinse your hair every three or four days with white vinegar (keep a squeeze bottle in the bathroom).
Yes... I can get mine that way. I always use conditioner and shine sprays. It gets really shiny when I use my flatiron!
I feel a hair shampoo commercial coming.
its this thing called a hair straightener
Guinness and egg yolk as conditioner (rinse it off) - try it ;-)
