There could be a few things going on. Do you have dandruff? Excessive dandruff?
I had ringworm for the last 10 years and it completely blanketed my scalp. It was a thick layer! I could not tell I had it other than dandruff and some scabbing on my head. I would consider getting tested for ringworm, which is caused by both fungus and parasites. If you do have it, you’ll need to kill the parasites internally while using a few types of special shampoo. I highly recommend this one shampoo sold by vitamin shoppe “anti-dandruff shampoo.” And you’ll also need a selenium sulfide shampoo as well to kill ringworm…
Hope this helps! I was able to improve my hair with the protocol as well as by killing the parasites.
