I use head and shoulders and it has made such a difference in my sores .

I have PN on my scalp as well. I did have an infection from scratching my scalp and the dermatologist had to prescribe antibiotics. She informed me that no matter how much I wash my hands or clean under my nails, infection is still possible dume to the presence of bacteria. The dermatologist suggested taking NAC to combat the itching and to break the itch/scratch cycle. I also use Head and Shoulders Bare and prescription scalp oil as needed.

Good luck. I hope you feel better soon.

It's possible, I suppose, as it gets to other parts of our bodies many say it doesn't. Like ears & nose. I also was my hands a lot, my Dermo asked me why... ??? Duh! So I still wash them a lot, and try to ensure I use a good thick lotion on tips, and have used a lot of Vaseline on hands and feet, especially in winter and summer when they get the dryest.

Hasn't it though? I found the suggestion on this very website! I use the Bare formula because it contains no additives. I also use Dove sensitive skin and Lubriderm moisturizer.
