[MENTION=135579]Heisenberg[/MENTION] Sir, Waiting for your reply.
First of all it is important to know that you do have SD. Sometimes it can be misdiagnosed but we will assume you have it for now. You haven't mentioned having it on your face so I will also assume you only have it on your scalp and so it should be easier to treat because I think you have a mild case of it.
I think it would be good if you can Google the symptoms for your own peace of mind too. Don't go on the pictures because they are the absolute worst case scenario (something I had). SD is a chronic and lifelong condition, but contrary to popular opinion you can be clear of it 99-100 percent of the time if you find your solution. Your skin is a complex organ and everything that works for one person will not work for you. For example, if I apply an ointment twice a week and it works for me, it may not necessarily be enough for you. Right now though, i'd like you to follow my advice completely, at least for two to three weeks.
SD is fungal in nature. We have to treat it both internally and externally. Remember whatever I tell you, may sound hard at first but it becomes a lot easier once you are clear. You can take stuff out of it and see how much you can get away with. But only when you are sure you are clear. It spreads easily when it is present so you need to be aggressive while it's there.
External treatment:
First, you will get a SLS/SLES free shampoo which you will use for the rest of your life. That i am afraid will not be an option. And I recommend this to everyone even if you don't have any scalp condition.
Additionally, you will get a couple of anti dandruff shampoos. My recommendation would be H&S and Selsun blue. Active ingredient in both are different but very good against the fungus that causes SD. Different is also important as I will explain later. Get a packet of baking soda (not baking powder please) and a bottle of Apple cider vinegar - the two best natural topical anti fungals.
Lastly, you will need coconut oil. The cold pressed kind. It needs to say cold pressed and should not be the refined kind because that kills off its anti fungal abilities. If you live in Karachi, you can go to Saddar where they press the oil out in front of you and that should suffice. If coconut oil doesn't suit you for whatever reason, you can use grapeseed oil which doesn't have anti fungal properties but it will do for the most important reason we will be using it.
So this is how it will go - you will apply coconut oil at night before you sleep and wash it off the next morning with your SLS free shampoo. The coconut oil should not stay on your scalp for more than 12 hours so try to put it on before sleeping and don't put it on in the day. This is because while coconut oil has good anti fungal properties it also has something that the SD fungus feeds on. It has a positive net effect unless it stays longer than 12 hours. Grapeseed oil doesn't have any anti fungal properties as such but it protects yours scalp from getting too dry when you shampoo which in turns produces more oil and that's always yummy for fungus. However you don't need to worry about Grapeseed oil staying in your hair for too long. I'd start off with coconut oil. You need to have oil in your head before you shampoo at least until you are clear.
After you shampoo your hair you will use a spray bottle to spray Apple cider vinegar on your scalp. It may burn but that's a good thing and the burn will be gone in a few minutes. It may also have a really horrifying smell but don't worry because you will wash it off in about ten minutes. It is important you use Apple cider vinegar after washing off your shampoo and leave it on for at least 5 minutes. 10 is good and you can wash it off. The rest of the day you will not let water touch your scalp. The following day you can shower but again don't let water touch your scalp.
At night you will repeat the process, coconut oil at night, shampoo in the morning with a SLS free shampoo and a good spray of Apple cider vinegar and then a final rinse with water to wash it off. Make sure the Apple cider is sprayed on your scalp and not just your hair. So basically you are going to shampoo every other morning only. Not every day and not every two days etc. Thats very important. Obviously you will use coconut oil the night before the morning you will shampoo only.
Let's say you washed your hair on Monday morning as I have told you to wash it (coconut oil, SLS free shampoo, Apple cider rinse), next will be Wednesday. Friday will be different though because you will use your anti dandruff shampoo instead of SLS free shampoo. That will be the only difference on your third wash. Then you'll do a normal SLS free shampoo on Sunday and again on Tuesday. Thursday will be Anti dandruff shampoo again except this time you will use a different anti dandruff shampoo. So if you used H&S last time, you will use Selsun blue this time. It is important to rotate the anti dandruff shampoos because they stop being effective otherwise. In short, your third wash will be an anti dandruff shampoo. You can go longer without it once you are clear. But it's also important not to just wash with it every time because that would make sense right? No because it doesn't work like that and it also has SLS which we don't want to use on every wash. I also told you to get baking soda but let's ignore it for now because it's more important for the face and we will only use it on scalp if this does not get you 100 percent clear. You will do this for two three weeks at least and tell me how it goes. You can be more flexible after it's clear which you will have to experiment with.
Internally:
All my dermatologists told me that what you eat has no effect on your dermatitis. That turned out to be the biggest BS a doctor has ever told me. While you are on this regiment you will absolutely avoid everything with milk. Especially milk itself. So avoid stuff like cheese but avoid milk completely 100 percent. Once you are clear you will be able to introduce it back and see how much of it your body can take. Milk might not be a cause for you at all but it's better to eliminate it for the first three weeks to be sure. Some others have had problems with stuff like sugar and gluten but it's not a trigger for me. I can also have anything now except direct milk without it causing an issue. So I enjoy my pizza and whey protein shake. You need to avoid it until it's gone. If your case is really bad you might want to consider other elimination diets too but for most people it's milk so start with that until you are clear.
Lastly but most important, raw garlic. Best anti fungal in the world period. You will cut up a clove of garlic into small pieces and swallow it with water every night. Repulsive for some but I was desperate enough and it is the best thing I tried. An alternative is Biotin but it gave me side effects at 5000 mcg like acne and it wasn't as effective but still good if you refuse to have raw garlic. Just do it until you are clear at least. Also try to get zinc 30 mg and have have it once a day but most important here is garlic and avoiding milk and it's products until you are clear.
I hope this helps you. Please let me know if you have it on your face and describe the condition on your scalp in detail. Does it itch all the time? Dead skin come off which I'm assuming you are confusing for dandruff. Looks like raw skin once dead skin comes off? Burn? Ask me any questions you might have. Good luck
