i second the hair diary idea, i did that as well, and used it in a blog..... have you thought about that you may be protein sensitive? if my is is really dry i sometimes think that some sort of protein slipped into my routine. I was still having trouble so i stopped using products al together and was just using nautral things, now i only really use oils and a natural condish.

my hair: 3c, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
my hair goal length is bra strap length when curly.

I also blog about my hair journey, please feel free to read and comment/ask questions http://www.naturallycurly.com/blogs/...air-blogs/2494
