For the past week or two I have had extremely greasy/oily hair and never used to. Does anyone know if it could be pregnancy related or something else? I regularly change shampoos so its not a build up of shampoo or something. Also, I tried not using conditioner for a few days to see if it helped and it didn`t. As soon as my hair dries after taking a shower it looks greasy! Its so gross, any suggestions?
