I'm looking for ideas, too. My 4-yr-old son has XLI. I have tried T-Gel shampoo and dandruff shampoos, but they are so drying, they make the problem worse.
What kind of shampoo works best for daily basis? Should it be something "moisturizing"? Does conditioner help at all or is it irrelevant?
For scale removal, our dermatologist prescribed Carmol Scalp Treatment Lotion, which works very well and does not seem to burn or itch my son's scalp, but is very expensive (>$100/tube).
