My 15 year old son has been suffering from Seb derm on his scalp and along his hairline for months now. Nizoral shampoo did nothing so he’s been alternating between regular Head & Shoulders and Vichy Selenium DS shampoo (he washes his hair every other day)and got prescribed Locoid by the GP. The Locoid worked but it’s very difficult to quit as after 3 days without Locoid it’s always starting to return. Could anyone advice on a routine that would work to keep the Seb derm at bay a bit better without having to resort to Locoid all the time? His hair gets oily very quickly so would daily washing be a better idea? I would also like to incorporate MCT oil as I’m reading so many good things about it. Could anyone advice us?
