    Hair Color Chemistry: How Hair Coloring Works

    Apr 23, 2018· How Hair Lightening Works. However, bleached hair tends to have a pale yellow tint. The yellow color is the natural color of keratin, the structural protein in hair. Also, bleach reacts more readily with the dark eumelanin pigment than with the phaeomelanin, so some gold or red residual color may remain after lightening.

    Chemistry Fun Molecule Project Ideas ?! Help Please ...

    Feb 26, 2009· Hey ! So for chemistry, we have to make a molecule structure (3D) but to make it more "fun" (and time consuming... =P) we have to make each atom look like what the molecule is. For example, if I do chocolate (theobromine) as the molcule each atom would be made up of chocolate. Now obviously, chocolate would melt, I'm not that artistic so I can#39;t make 3D models of chocolate.
