Just wondering if anyone else has been using squaric acid for treatment. I was using a 0.1% solution. My dermatologist prescribed this to me and for the last couple of months my hair started to regrow and the dermatologist kept saying "it's working". It also kept the scalp pain in check which was great. Because scalp pain equals hair falling out in my book. I was really excited that this might be the solution. Until 2 weeks ago when the shedding suddenly started again and it almost seemed to come back with a vengeance now. Scalp hurts again and hair falling everywhere. It's so frustrating, especially after it took so long to regrow and then it just all falls out within a few weeks. Now of course I am doubting that the squaric acid works at all. I also have a prescription for 0.25% squaric acid which I haven't used yet. Maybe I need stronger stuff to kick it to the curb. But stronger stuff also means more itching I am sure. Just wondering if anyone had any positive experience with the squaric acid and how often did you apply it? When I started out I applied it almost every day and towards the end only once a week.
