How can you only wash your hair once a week?
every few days I need to "reset" my hair so could I get in the shower and just wet and condition it or just wet it? Or does that count as washing your hair?
Sure you can, in fact either one is a great thing to do to refresh your hair and keep it hydrated. There are no rules as to how often one should wash their hair anyway. Each person should do what works best for them.
