I am a male in my mid 30s and have had scalp psoriasis since I was a kid. It varies in severity and sometimes will go away for months. I have even had it disappear for more than a year at a time. The last couple of years it has been consistently there, but not bad. In the Spring it returned full force, the worst it has been in 10 years. I would be fine throughout the day after washing my hair, but by late evening and certainly the next morning I would develop an extraordinary amount of plaques. The psoriasis also started migrating to areas of my scalp it typically did not inhabit.
I live in the Midwest and a month ago I spent a few days in Las Vegas. At the exact same time I added 1 teaspoon of L-Arginine powder to about 4 ounces of regular head and shoulders shampoo. I have been using head and shoulders shampoo for years. I added the arginine as an experiment to see if it would have any effect on my age related hair thinning. I have had very little scalp psoriasis since I started this. Maybe 10 plaques total in one month, less than the amount I was getting in one day. Most mornings this month I have woken up to a completely clear scalp. And not once have I felt like I need to wash my hair before going out in public.
This could be complete coincidence as psoriasis is something that comes and goes from my life with no apparent reason. The remission could have been triggered by my travel to a dry climate. Or it could have been triggered by the weather change going on in the Midwest. I will note though that I spent some time in a dry climate over the summer and it made my condition worse. It has also only been a month, which is a very short time to judge the impact of a supplement.
So there are the caveats. But I wanted to share something that seems to be working for me. There is an area of my scalp that had a plaque everyday for at least a year and it hasn’t had one in over 20 days.
For full disclosure I use OTC Nizoral every other day (sometimes less) and regular head and shoulders with NOW brand L-Arginine powder added to it (1 heaping teaspoon of powder to 4 oz. shampoo) on the other days. When I wash my hair I gently massage it into my scalp and let it sit for a couple minutes. And then rinse it out well. The only thing that has changed in my long-term routine recently is the addition of L-Arginine powder to my shampoo. Whether or not that is the variable that caused my scalp psoriasis to go away is unknown, but it probably wouldn’t hurt to try if you are looking for a new approach.
Sorry this is so long, I wanted to be thorough as possible. I plan on experimenting with the amount of arginine and also plan on adding L-Citrulline to the mix.
