So I can't speak to how to wear a pixie cut with curlys, but I know others on the forum can.
As far as where to start with CG: Yes, do a final clarifying wash with a shampoo with SLS. Make sure it doesn't have any silicones. (here's the list
of all the ones that hide in hair products).
Then, get a thin conditioner to co-wash with, Suave is a favorite around here and can very often be found for around $1 per bottle. (I like the coconut one!). I also use VO5 Herbal Escape Balancing Conditioner, which I believe was only about $3. After your final shampoo, you'll co-wash going forward. Just use a blob of conditioner to scrub dirt and buildup off your scalp.
Then you'll want a rinse out conditioner that can be either rinsed out completely or left in your hair. Favorites on the forum include Tresemme Naturals Nourishing Moisture conditioner (about $5-$7 at drugstores, grocery stores, Target, etc) and Generic Value Products Conditioning Balm from Sally's Beauty Supply (around $7-8, sometimes on sale). The CG method says to saturate your hair with conditioner, until it feels slick like seaweed. You can either rinse most of it out, or rinse minimally to leave the conditioner in (you'll have to experiment to see what works for you).
Then, finally, you'll need a gel. I know LA Look's line is popular, you can search the forums for more info. I use Biotera gel from Sally's.
Remember, no terry cloth towels touch your hair -- use an old t-shirt instead.
You can also search naturallycurly for the CG method to get some more guidance. I picked up the Curly Girl book and I still reference it for help.
Whew, hope that helps. PM if you have more ??s
