Can the side effects of TCA be permanent?

This tca peel was done by me, at home, not by a doctor! under 15%. Can a tca peel done "improperly" at "home" cause hair loss and hypopigmentation?(white streaks in skin/beard) What can i do if this is the case? =( If it can't cause hair loss even if done improperly please be clear and specific. Look closely at the whiter areas in the picture. Peel was 1 year ago. These are only "after pictures," this week. 'Recommendations' otherwise for improving my skin please? Help. I use tazorac and duac.
