once a day, usually in the morning cos less bad hair days this
way. if i'm out and perspire, i'll wash again at night and the next
morning will do a light wash instead.
treadstarter, even if u live in a country where winter is 365days,
once a week is not enough for proper personal hygene. try washing
your hair more often pls. using a conditioner on the ends of your
hair will help with "stiff" hair.
btw, for hair dun have moisturizer. have conditioner (leave
in/rinse), hair mask, hair oil, hair serum, hair ampil (sorry dun
know spelling), etc.
