I just started to henna about a month ago and I can still smell it on my hair, and it STINKS. I wash anywhere from 2-4x/wk. Lately since it's getting colder my sebborheic dermatitis is acting up so I've been washing (w/poo) every other day and DC after. It still smells like henna. Does anyone have any advice on what I can do to get rid of the smell? Will I have to wait until my next one and add some sweet smelling EO's?
