All the steps I've taken to prevent shedding (mostly from jrob):

1. Replaced my shower head with one that has much better filtration (I can feel the difference from this alone)
2. jrob's shampoo/conditioner/sealer combo
3. Satin pillowcases (still adjusting to them, I find it hard to sleep with them for some reason)
4. Wide tooth comb when my hair is knotted after the shower

Unfortunately because the partial I'm using isn't big enough, I rely on a combination of dermmatch and gel to blend the hair - and this usually necessitates that I wash my hair every day or every other day. So much for keeping it to a minimum...
