My doctor just gave me a shampoo sample called DERCOS by Vichy Laboratories. It contains selenium sulfide. I’ve used it 2x - so far so good.

Be sure to leave the oil on for awhile 4 hours using the cap that comes with it.
Then shampooing it out and rinsing it all out.

That sounds about right.

Ask your doctor for prescription of sell selsum blue. Really scrub this selsum into ur scalp really good and leave it in overnight every night for a week and ur skin if ur having problems there to. And after a week it should heal up for at least 3 straight months me and my son use this. Don’t buy dandruff shampoo over the counter u want ur doc to prescribe you some.
