Hello & Welcome Stekelly.

I found Arachis Oil (Refined Peanut Oil ) is good for the scalp.
You leave it on over night then wash it out with a good shampoo in the morning. Use a fine tooth comb on it. A nit comb is ideal. Then give it a good brush.
You can get this from your G.P. or health food shops.
I used this when my scalp P was very bad or dry. I used to have scalp P very bad.
DONT USE if you have a peanut allergy.
You could also try T-Gel or Alphosyl Shampoo. You could also try Bettamouse shampoo which you can only get from your G.P. as it contains steroids. I used it once and have never looked back.
