The first time I had this condition was 2.5 years and it lasted a painful 3 months. I just had an out break in November and it lasted till now. I strongly believe it was caused by a shampoo conditioner. My cure after trying many was using a skin cream ointment with Clotrimazol 1%, Neomycin 0.5%, Dexametaona 0.04% and I mixed it with full strength Iodine-iodine is a strong fungicide. It makes a good dark red paste. I popped the pimples and rubbed in the mixture. When I started my lymph gland in the back of my head was swollen and hurt horribly and after five days it is now normal size. No more pimples and it works. DO NOT PUT STRAIGHT IODINE ON THE PIMPLES AS IT WILL BURN HORRIBLY-TRUST ME. The mixture will sting a little but not unbearable. It worked for me. Try it on a small area and see. I saw relief within a few hours.
