Is it normal to wash my hair only once per week? i'm female.
I find that my hair only needs to be washed once a week; any more often, and the natural oils get washed away and my hair gets dry, as I dye my hair to get rid of the grey hairs. Also, I use very good quality shampoo ($US35 per bottle of shampoo and the same for the conditioner - our prices are almost double US prices) and I save serious money by only washing my hair once a week. My hair always looks fine.
