Breakage :(

I keep having issues with breakage. I know that the problem lies in protein/moisture imbalance, but I don't know how to meet in the middle, so to speak. For example, I did a homemade protein treatment last week, because I keep having broken hairs in my comb when I comb my hair. Not a lot, about a medium amount, but still. My goal is a few hairs or no hairs. And I know it can be done because I've watched girls on YouTube like Nina Pruitt and ULoveMegz have little to no broken hairs in their combs.
  So my homemade protein mix was one whole egg and some extra virgin olive oil. I left it in my hair for one hour without heat (or else I'd have scrambled egg head) as instructed by an article on hairfinity.com. After I rinsed and conditioned, I still had some breakage. :(
  The next few days, I also noticed that my hair was hard...a symptom of protein overload. But....how can I have protein overload and still have breakage?? I don't get it. I hated my hair feeling hard, so I deep conditioned on dry hair overnight with extra virgin coconut oil and my hair felt SOOOO much better :) I love my coconut oil!!
 Anyway so...I think I'm just going to continue to do a weekly protein treatment. Probably not with an egg, but I use my Aphogee 2 minute reconstructor and it works well. I guess trial and error leads you to the hair of your dreams right? Here of some of my dream hair lengths :)

My main goal length is bra strap length, but I recently decided my short term goal is full arm pit length because...it's still so long and pretty and I would be BEYOND happy if I got there and not bra strap  length. It just seems more within my reach :)
