Well I have joined a few challenges around here, but at the end of the day what I'm finding works best for me is sticking to my regimen. I've adopted a lot of the same principles to my everyday hair care, so I don't think there's anymore I can do to change things or make it better. For me I do from time to time switch around products when my hair seems like it needs it, and steal some techniques found in various challenges... But at the end of the day, keeping it simple works.
