I am seriously considering doing this. When I had locs I did them myself so I don't see why I can't with relaxed hair. Only problem I foresee is cutting. I like my hair in short hairstyles. I gave it a trim last week cause it was getting too long and I couldn't get to the hairdresser. Except for a little patch at the back of the head (which is hardly noticeable), it looks pretty good.

I just need some more practice.
