Greetings. Hair color allergy may lead to occurrence of eczema , dandruff and oozing of serous liquid from scalp. Please see a qualified dermatologist. Also he'll benefit from a low strength corticosteroid shampoo. If oozing is too much, and if pus like then anti biotics may be necessary. Hope this helps. Further queries may be sent on follow up messaging. Warm regards.
