After 15 years of struggling with seborrheic dermatitis of the face and scalp I am finally free of this horrible condition. For me it wasn't a deficiency but something I was allergic too which caused my body to react and therefore create this condition. Everyone is different but if you are still struggling with this condition and cannot find out why here is my feedback. I used and tried everything under the sun and the sun (uvb therapy). Vinegar, which was a big help for awhile but not a cure all, all types of cream, soaps, shampoos, vitamins, mineral, amino acids, immune boosters, immune suppressants etc. All of this adding stuff here and there but did not think to take a look at stuff I use everyday. Sulfates are my biggest enemy, especially sodium laurel sulfate. This is my cause of seborrheic dermatitis. It was in the shampoo I was using for 10 years and I quit using it and my scalp got was free of flakes but my face was not and I could not figure out why.
So fast forward 5 years later I went back to using a shampoo with SLS and bam it was back on my scalp worse than ever and my face got alot worse. So I switched my shampoo back to an all natural and my scalp cleared but my face remained a red flaky mess. So one day I checked every product that I used and the SLS was in the last place I could imagine... In my toothpaste!!! I felt so dumb that I had never seen that before.
So I switched to an all natural toothpaste that is SLS free and viola... Face is as clear as ever. I guess it was circulating through my gumline making my face breakout. Ok that was the silver bullet. But you must repair the skin barrier that had been damaged by this chemical. I found a product called _____ cleanser and moisturizer that is SLS free and this repaired my skin. I do not use it anymore simply because I do not need too. *I am not trying to sell anything on here just trying to help someone if possible. Just avoid all SLS which is in 99% of products out there. Peace out. Pat
