I have just been told I am disgusting by a "friend"
I only wash my very short hair once a week (sometimes longer) because frankly I hate having wet hair, I hate the feeling of water down my neck and I hate my head feeling cold.
I also hate getting out of the bath or shower for this reason but obviously force myself to do this once a day.
I use dry shampoo inbetween and noone has ever commented on my hair being a mess and I actually find it easier to style when it is a bit dirty.
