I've used natural soap bars for cleansing for almost five years. They were the "rage" on nc.com, at the time, but have since fallen out of favor because of the high pH. They are very gentle, just a little "more" then cowashing. For me, they remove the residual ingredients from the richer products that I use (my low porosity hair doesn't absorb everything.) However, they won't remove chemicals! Unless, they aren't "natural bars--Lush bars used to contain SLS (don't know if they've made any changes.)

My hair LOVES protein. I do at least one PT a week and use a lot of products with protein. If my products for the day don't have protein, I use a protein spray or some SKB as my first layer. My favorite PT is CJ Repair Me. While I can use gelatin in my okra gel (one package to 4 c of water), I can't do the gelatin PT (one package to 1/4-1/3 c of water.) It coats my hair and doesn't get absorbed.
