Hair gel

Hair gel is a hairstyling product that is used to stiffen hair into a particular hairstyle. The results it produces are usually similar to but stronger than those of hair spray and weaker than those of hair glue or hair wax. A version of gel, known as "Mousse", was patented in the mid-1980s by Michael J. Hoover.Fact|date=June 2007

Types

Many brands of hair gel in North America and the United Kingdom come in numbered variants. Higher numbered gels maintain a greater "hold" on hair, while lower numbers do not make the hair as stiff and in some products give the hair a wet look. A category typically referred to as "ethnic" gels are designed and manufactured specifically for sculpting the hair texture common to African Americans. Ampro Industries is a common example of this category.

Some forms of hair gel include temporary Hair coloring for the hair, including variants in unnatural colors associated with various subcultures, and is popular within the goth and raver subcultures. Fact|date=February 2007

Cationic polymers

Cationic polymers are one of the main functional component of hair gel. The positive charges in polymer cause it to stretch, making the gel more viscous. Hair gel withholds procedures that allow men and women to make their hair styled and textured in ways they desire.This is because the stretched-out polymer takes up more space than a coiled polymer and thus resists the flow of solvent molecules around it. The positive charges also bind the gel to the negatively charged amino acids on the surface of the keratin molecules in the hair. More complicated polymer formulas exist, e.g. a copolymer of vinylpyrrolidone, methacrylamide, and N-vinylimidazole. [http://www.corporate.basf.com/basfcorp/img/stories/wipo/haargel/Haargel_e.pdf]
