I'm going with dry scalp as I've had that problem before with the same symptoms... It just kinda went away for me. Leave the salt out of the deep cleaning thing and see if that helps.
yeah i was wondering if mebbe it was the salt or the lemon juice. i didnt use it the first couple of times ( teh lemon juice )
Something no one has mentioned is Rosemary tonic. Use dried rosemary, and put it in boiling water, use that stuff on your scalp. Helps a lot.
I remember getting scabs for the first few weeks after backcombing. Eventually they went away, but now even 10 months later I've got dandruff unless I use Nizoral every day, and even then I still have some.
