The only thing that helped me with my Seborrheic Dermatitis is tea tree oil and the Scalpicin with salicylic acid, but then started using Rite Aid Brand of Scalpicin which I had better results. I don't have that many flakes, but the itching is unbearable. What's funny is when I tried the tea tree oil by itself it did not do much. And when I tried the salicylic acid by itself I only receive temporary relief. But when I alternated the tea tree oil and the salicylic acid every other day I received tremendous results. What I do is one night I put on Scalpicin and leave it in all night and take a shower in the morning, and the next night I apply the tea tree oil. I had a really bad case, so I put on a lot (almost half the bottle per application). The tea tree oil has a strong odor that could smell up the house, just to warn you. Also note that there are two Scalpicin's. One contains hydrocortisone and one contains salicylic acid. So if you try my method make sure you get the right one. For me, the hydrocortisone only temporary relieved my itching. I would by the Rite Aid brand or the CVS brand that says Scalp Relief of Scalp Itch and Dandruff Relief, as I received good results with these. Again I tried almost all of the products on the market, also Apple Cider Vinegar and Lemon Juice, and this is the only thing that has helped me. Another thing to note is your itching might occur on the day after the night you used the tea tree oil, but it will go away the next day when you take a shower the day after you put on the salicylic acid. I used to have a rough scalp and this has truly helping my scalp return back to normal.
