I have coloured hair. My scalp can be very scaly and dry but have greasy hair, need to wash every day.
I used to just avoid washing too often as i had long hair and by wearing it up and using dry shampoo managed fine.
I have a short bob now, so i am washing every day and my poor scalp is in tatters.
Have been reccomended WEN by a friend, also aveda but wanted to canvass opinion before investing in either as bith are pricey.
Cheers
