I've had this since I was about 7 and it never goes. I use betacap scalp solution but don't think it's helping anymore. Recently my gp have me dovabet scalp gel but it makes my hair very greasy. Normally i wash my hair every 3-4 days. I've tried no shampoo, no sulphate .. no improvement. I now use selsun shampoo but my head still itches a lot - sometimes I wake up in the night scratching.
Does anything help?
