Hey girls! I'm 9 weeks pregnant! My hair is falling out like it did before pregnancy and still does now! In summer I was taking Roaccutane, I know they have side effects, but do they still work? Has anyone experienced this? What can I take? Of course, I will consult with my doctor! But I forgot to mention that first appointment with the doctor...
