Why is the hair's elasticity so important?
Elasticity is, in my opinion, one of the most important properties of hair. This is the hair's ability to be able to spring back to its original shape and length without damage. Wet hair that is in optimum condition can be stretched up to 25% of its length, and return back to its original length when dry. As an experiment, if you were to hold a piece of hair about two inches long in your fingers and pull, you would be able to see considerable movement.
Hair's elasticity depends mostly on the keratin levels and sulphide bonds in the cortex of the hair. These can be quite easily damaged by chemical treatments, such as relaxers, perms, or bleaching. These chemical services will then create poor elasticity in your hair. This will limit the amount the hair will be able to stretch. The hair will also not curl, be weak, fragile and will break easily. Natural and artificial sunlight will do the same damage. Poor elasticity can be rectified by the use of good treatment conditioners that contain wheat, rice and corn proteins. Treatments containing Keratin protein are also acceptable; however, the natural ability of vegetable proteins to immediately penetrate into the hair shaft make them a better choice.
You should wait at least two weeks after a chemical service, or until you get the stylist's OK, before considering braids.
