And away we go...
Day 1: After the first treatment, my hair pretty much felt like straw. I brushed it a few times with my trusty Mason-Pearson brush, and it's a lot softer now. Still not great, but better.
Day 4: I did it again last night. Today, my hair is still kind of "crispy" and dull. I'm still going to wait it out though.
Day 9: I caved. After 3 days of camping, my hair was full of soot and dust. Last night, I washed it with shampoo. But I just used a very small amount, and followed it with an ACV rinse.
