I have had bad eczema for a couple of years on and off now.
I prefer not to use setroid creams but recently that seems to be the only thing that works. I am taking flaxseed oil daily and I think that has worked to improve my skin slowly. I will have to see if my skin stays good after I stop the current usage of steroid cream. If it doesnt then I am going to try and see a dermatologist.
I used to suffer from a mild form of psoriasis on my scalp in my early teens...it used to flare up when I was stressed. Now, it's gone alhumdulillah but I still have to be careful about what I use in my hair just because I don't want to trigger it off again. I make sure my shampoos and conditioners are mild. I used to use baby shampoos but now I use a shampoo that doesn't contain SLS's and parabens. Also, I avoid using any stay-in hair products in my hair, I'll use hairsray very very rarely. I also apply oils in my hair whenever I can just to keep my scalp moisturised.
