I'm so interested in trying this product!!! It, to me, is a more affordable version of Design Essentials. My issue is frizz. I can rollerset and my hair be perfect. Then when I walk outside, frizz central (South Florida problems). When I did a BKT years ago, that was the only time I had frizz free hair (regardless the amount of moisture in the air). I've been looking for an alternative to the BKT and settled with Design Essentials. I haven't yet purchased it and was excited when i saw the D&L Anti-Reversion. Will definitely be purchasing. Many ladies upthread questioned the usability or their idea of reversion. It's not a leave-in, it's a treatment. It deals not with relaxed hair reverting back to natural, but rather new growth reverting back once you use the product. Ladies who want frizz free hair in between relaxers should really use this product!!!
