I have a couple of scabs on my scalp that are concerning. I am a medical esthetician so am aware of most conditions. I just returned from a camping trip where I did not wear a hat and got sunburned on my scalp. Am of Scottish/American Indian descents. The scabs are very light greenish and not itchy. I did just finish a round of antibiotics but do not have any symptoms of candida/yeast overgrowth and replenishing good bacteria.
