Just like everything else, this is a journey.
I started mine on my own after I read a lot of websites and watched videos of others doing their locs. I paid close attention to how they washed and dried their baby locs.
And if you don't want to fully immerse them, there are other options like just cleansing your scalp. (I think someone I knew used a product by Taliah Waajid?) You should be able to feel the direction she twisted them in.
Hopefully, that could hold you until you find a new loctician. The hardest part is getting your hair all parted and the locs started and those are the only things I would change if I could do mine over!
Also: please don't think of it as "tainted". This is a journey and sometimes there are unexpected stops, turns and waits. This is a "wait". What if she hadn't shown her colors so early and REALLY jacked your locs up?
The journey continues and YOU keep on being positive!!
