I keep reading about "sealing" the hair and how important it is. I looked it up and got a little overwhelmed by the results. So much information! Can it be as simple as dropping a few drops of oil onto my palm and grazing the hair when it is damp or dry? If so which is better? I could also add oil to a spray bottle and mist the hair I think if I mix it with water. Which technique works for you and why?
