Hair Conditioners


What is a Conditioner?

Our hair is made from a protein called keratin, which has a high percentage of amino acids that have negative charges. These negative charges make the hair 'frizzy'.



Most hair conditioners contain positively charged molecules. The positively charged surfactants in hair conditioner are attracted to the negative charges in the hair, and do not rinse out completely with water. When the hair dries, it is coated with a thin film, which adds weight, makes the hair easier to comb, and prevents static electricity from building up and 'frizzing' the hair.
 
Types of Conditioners

Moisturizers 

 Are concentrated with humectants. Humectants are compounds that attract and hold moisture into the hair. They may not necessarily contain botanicals or protein.


Reconstructors

The main purpose of a reconstructor is to strengthen the hair. 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).


Acidifiers

This category is great for people with fine textured hair. They do create shine, and add elasticity. When a product carries a pH of 2.5 to 3.5 it is normally termed an acidifier. This pH will close (compact) the cuticle layer of the hair. The result is shiny, bouncy hair. Acidifiers do not weigh the hair. They do create shine, and add elasticity.


Detanglers

Most detanglers are acidifiers. They close the cuticle of the hair which cause tangles. Some "shield" the hair shaft with polymers. Some detanglers are instant; some take 1-5 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."
  Useful Tips  

  • Conditioners are generally used after shampooing.
  • Keep the conditioner on your hair for 5 minutes before you fully rinse it off.
  • For fine hair, rinse off the conditioner immediately.
  • The drier your hair, the longer you need to apply a conditioner.
  • Avoid hair conditioners containing alcohol.
  • A conditioner is not meant to lather, so don't apply huge amounts to make it lather.
  • Rinse it off thoroughly each time, or it may cause build-up on your hair, making them heavier. 
 Natural Alternatives

  • Cider vinegar - Put one or two tablespoonfuls into a pint or more of water. This helps the acidity of hair, leaving it shiny and silky.
  • Lemon can also be added to the rinsing water.
  • Tea is another slightly acid hair rinse which has a conditioning effect. 
  •  Henna powder is also good for the condition of hair.
