Day 17, using 5% twice a day on 40% of my scalp. Honestly, I have not had a big flare up yet. It's almost like it's not working. The red sores on my scalp are slightly worse and are painful, but not like expected. Areas around my sores are not red or dry. I'm assuming it hasn't activated yet. I've read that if you don't have a flare up within 4 weeks to go back and see your doctor.
