Meli said:I have been sealing after I have shampooed and conditioned my hair. I don't know if that's the right thing to do. I hear some of you are applying oil to dry hair, before it is wet or shampooed. I bought castor oil and the directions read to apply the castor oil and shampoo at the same time and wash it out. How do I know when to apply the oil to dry hair verses applying the oil to post-shampooed hair. Should I ever apply the oil to hair after it has been conditioned?
