I was diagnosed with it at about... 16. I always had some dandruff not much dry skin on my body but it started to get major and sometimes I'd have sores. We'll leave it at that... I went to about 4 derms. All different ages, and ethnicities so no one can say Dr.Billy was too old go see Dr. Paulaquani she's 34 from Morocco
where they know more about skin lol. They all said the same thing and gave basically the same solutions.
Steroids, Zincs / Tars / Acids Shampoos. The steroids... Well they work for many Desonide Lotion did wonders for me BUT stop using it and it comes right back. Keep using it and your skin will thin and it probably will stop working like it did for me. The shampoos they actually made it worse for me so after the derms it's on me. I did get one good solution. Stop using chemicals until your scalp is better.
So I stopped using dyes and chemical straighteners. Also I stopped using commercial soaps on my skin
Then I was clueless... If doctors couldn't help who could. The answer was ME
