Remedy that WORKED!!I also suffered from Pityriasis Rosea. What worked for me within days!
1. I took vitamin D 2000mg
2. Showered in cool water with Selsun Blue Medicated Shampoo ( morning & evening)
3. Moisturized skin with coconut & tea tree oil ( twice a day)
4. Did Photo therapy treatments ( not tanning booth) twice a week.
I believe it was the Photo therapy sessions ( 2-3 min) that were the remedy. By that evening of my 1st treatment the breakouts started drying up! The itching was GONE after the 2nd treatment. I had a total of four 2-3 min treatments. After that I continued to moisturize with "Eucerin Professional Repair" because the breakout areas were dry and dark...Within a week after stopping PhotoTherapy my skin was back to normal!!
