Wow, I forgot about this challenge. Since my last post, I did the BC. I only have 0.5 inch of hair on my head. I'm probably not going to need anymore heat passes.
This challenge flew by!!! I haven't even been considering using heat. I went from just making APL to Full APL this summer so this is something I will do every year from now on because it obviously works
After using the last heat pass, I did 'touch up' my straightened hair after about 10 days to make it last a little longer so technically I used 4 heat passes but the challenge did make me think twice about my heat usage.
