just use all different types of shampoos thats wot i doHow should shampoo be used?
I know Redken is a great shampoo that was #1 on the shampoo list in the newspaper and is used by most hair dressers. It is safe to use everyday, most shampoos are. Don't use the Nexxus one everyday if you've heard it isn't safe, use it two or three times a week instead. Head and Shoulders is definitely safe, my brother uses it all the time. Overall, most shampoos are safe to use everyday. Just wet your hair and scrub the shampoo into a big soapy lather. Rinse and add conditioner if you like, but don't over do it. Shampoo should only be a palm sized amount, and conditioner should be a penny sized amount. About once a month skip a day of washing your hair to give your scalp a rest and to leave some natural oils in.
i'd use head and shoulders i really dont like nexxus one bit it's seems liek it's really cheap i dont like it stick with head and shoulders
In general, I would not shampoo your hair every day. I would only suggest washing your hair every day if you have a very oily scalp. Consistent washing generally causes hair to dry out. I wash my hair every other day, and I normally use Aussie. Garnier Fructis, or Pantene ProV. They all work great.
lather. rinse. repeat.
