What are Hair Fibers?
Hair fibers (or hair fillers) are tiny filaments made from either synthetic of natural material that use a naturally occurring static charge to bond with existing hair. The result is a three dimensional increase in the volume and density of the hair giving the illusion of thicker locks.
But how does it work?
Well, every material has some kind of electrical charge whether this is negative, positive or even neutral. By matching the right kind of charge to that of your hair, you can create a firm bond between the hair fillers and your own hair.
A human hair is both negatively and positively charged with the majority of the strand being positive. By combining a negatively charged filler, a bond is created like an electromagnet. However, depending on the material used, and its inherent static charged, the stronger (or weaker) the bond. Material such as keratin derived from wool sources has a similar charge to human hair and may not always create a strong bond; however, it does look and feel more natural. Keratin sourced from a plant such as Gossypium Herbaceum has less of a similar feel to hair but creates a better bond due its more negative static charge.
Conversely, cotton and synthetic fibers have a greater negative charge and bond more effectively to parts of a human hair; though they don’t always look or feel natural.
Silcon has a negative charge but is not recommended as a product as it can cause respiratory problems if breathed in during application, particularly over a prolonged period.
It’s important to know that what you gain with a natural look and feel can compromise the integrity of the bond so do look closely at what kind of material is being used in the fibers you are considering.
