i have long dark brown hair and i want to add some dimmension to it. however, i have a skin problem that makes me have to use medicated shampoo. so if i got highlights they would strip out pretty easy. i was think maybe if i got some subtle highlights on the underside of my hair it may not be seen as much when it starts to wash out. i really dont know what this will look like. i dont think i have ever seen this done. how does it sound to yall?

not best pic, but can see my hair.
