Are you dyeing to have better hair? After trying out their new formula side-by-side with the old standby on hundreds of potential customers (new formula is on the right), chemists at Procter & Gamble may have made some headway in the decades-old dyeing process that always seems to leave hair dull and frizzy.

Thanks to hair's natural water-repellent coating, called the f-layer, droplets tends to bead up (left). When treated with standard hydrogen peroxide-dye formulas, however, the layer is easily disrupted, allowing water to soak in (right). A new reformulation, however, allows hair to be dyed without the same f-layer disruption, once again keeping the water out (middle)."; Tech_Frontiers_HairDye_080407[i++] = new Array("","Bad hair day","","http://msnbcmedia.msn.com/j/msnbc/Components/Photo_StoryLevel/080403/080403-Hair2-hmed-130a.hmedium.jpg","","Image: frizzy hair", "", "", "", "", "", "", "Courtesy of Procter & Gamble", "273", "284", "#000000", "", "", "", ""); Tech_Frontiers_HairDye_080407[i-1].body = "Bad hair day
Talk about a bad hair day. After five dye jobs and 12 shampoos, a clump of human hair shows the normal wear and tear of high-pH dye formulas that have long left their mark in the form of cuticle damage, split ends and a whole lot of frizz."; Tech_Frontiers_HairDye_080407[i++] = new Array("","Tame that mane","","http://msnbcmedia.msn.com/j/msnbc/Components/Photo_StoryLevel/080403/080403-Hair3-hmed-1230a.hmedium.jpg","","Image: Strand of hair", "", "", "", "", "", "", "Courtesy of Procter & Gamble", "273", "263", "#000000", "", "", "", ""); Tech_Frontiers_HairDye_080407[i-1].body = "Tame that mane

A closer look at what happens to dyed hair cuticles. After five dye jobs with a conventional high-pH formula, these magnified strands show significant surface damage to the scales of the cuticle, on average. Note especially the two strands on the right, where the cuticle has been almost entirely chipped away. The result can be dry, dull hair with plenty of split ends due to damage in the underlying cortex layer."; Tech_Frontiers_HairDye_080407[i++] = new Array("","Better hair","","http://msnbcmedia.msn.com/j/msnbc/Components/Photo_StoryLevel/080403/080403-Hair5-hmed-1230a.hmedium.jpg","","Image: Magnified hair strands", "", "", "", "", "", "", "Courtesy of Procter & Gamble", "273", "383", "#000000", "", "", "", ""); Tech_Frontiers_HairDye_080407[i-1].body = "Better hair
After five dye jobs with the new combination, Procter & Gamble chemists found that magnified hair strands show less overall surface damage to the scales of the cuticle. Note especially the three on the left. The result, company chemists say, is an overall smoother feel and shinier look."; // END editorial data
