Man, I feel you. I have those kinda days too. The ladies here have given you great advice. Six months- girl you are just getting in good!
This whole process takes time-- and it takes alot longer depending on where you are starting out. I know for me, I started off with a pretty bad head of overprocessed (colored and relaxed to death) hair. I think I've finally gotten the last strings of that mess off within the last year or so
First, Give yourself a little credit!
I know sometimes we have little triumphs that we tend to overlook on our quest for something greater. I know you're battling breakage-- but has it gotten a bit thicker? Shining a little more on its own? Feeling a little nicer? You know, showing the early signs of progress? Once you find your stride, you'll be good to go! So sit back, relax and try to understand what your hair is telling you.
I'd be careful trying too many regimens and techniques all at once. Give your hair a chance to clearly respond to something. Take a method/product, give it a whirl-- if it doesn't work-- scrap it. I wouldnt' even get into mixing stuff up yet. There are lots of great gems and strategies on this forum, but if you combine every last strategy you will be starting more threads like this one.
They can't all work together.
Your breakage could be a response to a whole myriad of factors. Listening to your stats it does sound like a protein issue to me. Naturals typically don't need that much protein, and most newbies typically don't need so much protein in the beginning either. But, your breakage might simply be a matter of you keeping your hands in your hair too often-- or your water might be hard.
Slow it down, sista! This is supposed to be fun!
