I used to wash my hair every other day, but my hairdresser used to tell me that its so dry and that i should wash it less.
Since then, i have "trained" my hair so that i only wash it twice a week and i noticed such a great difference in the quality of my hair. Its stronger and healthier than ever before! It was hard at first because i hated that oily look. But in a matter of a month, my hair just got used to it i guess!
Whats the norm for you ladies?
