Has anyone ever taken an antidepressant and it made their hair go straight? I've been on one since April 2011 and my hair is getting less and less curly. My hair is waist length and I used to be a 3a/b and now I'm barely a 2a. It's not just the length pulling out the curl because my bangs are about down to my eyebrows and they barely wave. My hair used to start spirally after it was 1" or longer. I use no heat at all, I haven't straightened my hair in 4 years. My hair is very healthy and thick - it's just going straight.
