I appreciate this write up. I was diagnosed with SD about 10 years ago. I had a huge white flaky patch in the back of my head that inched incessantly. I went to the dermatologist and they diagnosed it. I was prescribed Loprox shampoo and Olux foam which worked wonders but is too expensive. I’ve used Neutrogena T-Sal for years when it flares upeople but I have a very mild case that doesn’t require constant treatment. Today I purchasedon’t Dermarest shampoo as my scalp has been a little itchy lately. Hoping it works as well as Neutrogena but at a more reasonable price.
Also, I’ve noticed my hair doesn’t grow as well on the side and or in the area of my head that gets the flare up. It has grown but it’s much slower and not as full.
