Ive never used that shampoo but the good you can gage for yourself now that you know how your hair feels when the gunk is out. How often to clarify is different for everyone. I think some people do it like every couple of months.for a weekly cleanse, I use Shea Moisture Retention shampoo. Does that get all the gunk out? I do cowash everyday, but with a cone-free conditioner and I use cone-free products.You have to listen to your hair and find out how "clean" you need to be . . Like cocoj I do it every week because I use a lot of products ie gel, conditioners, butters, oils ect. I also cowash about every two days. I dont use cones but since my hair is fine i still get buildup easily. I need all product out of my hair once a week for clean slate. I just gave my cousin a Shea Moisture shampoo from the hibiscus line because it wasnt getting my hair clean enough.
