Hi, I have just made the decision to try squaric acid, it is a last resort, I have been doing the injections for 3 years and they worked and kept my hair in a condition to not needing replacement hair, for some reason they stopped working for me, so now I am in wigs.  My question is, I had the first spot of squaric acid put on my head on Friday as the trial at 2% I was expecting all kinds of reaction and nothing has happened, didn't even get red, irritated anything, does anybody know if this…
