Hi, I’ve had Lichen Planipolaris for 2yrs now. The best shampoo and conditioner I feel that doesn’t irritate the scalp is Vanicream. Anything hypoallergenic is good. I stopped dying my hair as well because I know it will irritate my scalp. Also, keep your scalp covered from the sun. Sometimes I forget to do that and my scalp gets so inflamed. Hope this helps.
