I had silky straight hair all my life. My last month on accutane I saw a weird change in my hair when the bottom has turned wavy.Then I stopped my treatment. I was told it will go back to straight but it’s been 3months and it’s still curly. I have also noticed that my hair growing from my scalp has turned wavy. Is there a chance that I get back to my old straight hair and how much time should I wait if so?
