Hello. I am new to all of this and am completely overwhelmed. I started massively losing my hair in September 2012 and within a two week time period I was completely bald. I am now receiving squaric acid treatments to hopefully restart the hair growth. The doctor said it could take up to two years to see if it works. Has anyone done this treatment or have seen it actually work? It's not painful, just expensive and time consuming (I have to have someone else apply it weekly).
