Removing Loc Build up

Last night I was talking to my husband about his locs, and the reason why he is starting to form a build-up in his locs. I do his hair every week, so there is no reason for build-up. I started thinking about what changed in his regimen and I came up with the following list:

1. Paul Mitchell Tea Tree pomade-which works wonders on his oily scalp
2. He was way overdo for a ACV rinse
3. He has been shampooing his hair with undiluted Peppermint soap

Now that I know the culprits, I am going to take matters into my own hand, and get back to what I know. I will keep you posted.
