Moisturizers
Are concentrated with humectants. Humectants are compounds that attract
and hold moisture into the hair. They may not necessarily contain botanicals
or protein but they often do.
Reconstructors
Normally contain protein. Hydrolyzed human hair keratin protein is the
best source, because it contains all 19 amino acids found in the hair. Human
hair keratin protein has a low molecular weight. This enables it to penetrate
the hair shaft (the cortex). The main purpose of a reconstructor is to strengthen
the hair.
Acidifiers
The key word here is "acid". Yes, it
is good to put acid on your hair. When a product carries
a pH of 2.5 to 3.5 it is normally termed an acidifier.
This pH will close the cuticle layer of the hair. The
result is shiny, bouncy hair. This pH range will adjust
the beta bonds to alpha bonds. Acidifiers do not weigh
the hair. They do create shine, and add elasticity. This
category is great for people with fine textured hair.
Detanglers
Most detanglers are acidifiers (see above). Most
have low pH's 2.5 to 3.5. They close the cuticle of the
hair which cause tangles. Some "shield" the
hair shaft with polymers. Some detanglers are instant,
some take up to 5 minutes to work.
Glossers
For the most part glossers are cosmetic. Most
glossers contain dimethicone or cyclomethicone ( very
light oils derived from silicone). Used in small amounts
they reflect light. Also, they are one of the best products to control the "frizzies."
Oils (E.F.A.'s)
If you have dry hair you need to add oil to your hair. The scalp
produces a natural oil called sebum. EFA's are the closest thing to natural
sebum (sebum contain EFA'S). EFA's can take very dry and porous hair
and transform it into soft pliable hair.
