I use the keracare shampoo and conditioner Keracare are also makes an oil sheen with humidity block. if your interested in oil sheen. I know some people prefer serum. I personally like it for my relaxed hair. Use sparingly, on shampoo day after roller setting I use it, then on my ends maybe one more time in the week before wash day again. I also like a bump too so I roller mine on satin foam covered rollers. But the only thing the oil sheen had mineral oil, but I personally don't mind it.
