I was just about to post the same thing. I have the exact same problem. I think the twists may be my problem. I wear mini twists a lot and I think I lose a lot of hair with the process of putting them in and tangles from shed hair when I remove them. My new plan is to add protein to my regimin to stop breakage and wear twist outs (twisting every other night). Not sure if this will help with retention, but I have to change something. I know my hair will get more moisture but I don't know if it will be too much manipulation. Basically I wrote all of this but I have no advice.
