I have tried head & shoulders, selsun blue, maximum strength coal tar shampoo, and nizoral, but none work. The coal tar and nizoral maybe worked a little bit for awhile then stopped working. Apple cider vinegar worked well for awhile, but had to be used pretty often and can still be smelled the next day. Now, even it doesn't work that well and has to be used every day.
I've heard to add some tea tree oil to your regular shampoo. I bought some but am unsure how much to add. Anyone know?
Any other thoughts on how to stop this or what might cause it?
