Hi,
I had foliculitis on my back for years. I tried everything but eventually went for the epsom salt bath option and it really worked. After 2 weeks it was miles better but I was told to do it for 2 months to make sure it didn't come back so it can get quite expensive. This stuff from amazon is quite cheap and 2kg can last a month if you don't have too much water in the treatment bath. http://www.amazon.com/gp/product/B000FVUJ28?ie=UTF8&tag=wwwtvcatchphr-20&...
You can get it cheaper on ebay, but I'm never quite sure that it's the real deal.
3 months after my last epsom bath and i'm still clear so fingers crossed
good luck everybody!
