Hair extensions are made from a range of human and synthetic fibers. Synthetic fibers include Kanekalon and Toyokalon, and can differ from brand to brand. Synthetic hair in general is far less expensive than human hair, and is available in a wide array of colors and textures, from natural to extraordinary. However when considering hair extensions you must keep in mind that synthetic hair is just that synthetic and can not withstand hot temperatures so straightening and curling the hair is not an option as it will singe. Human hair is available in many different grades, and may be advertised by ethnic origin; India, mainland China and other countries in continental Asia are the top suppliers for ‘virgin’, or unprocessed hair.
Synthetic hair is made of a wide array of different synthetic fibers. Synthetic hair, just as human hair, comes in weave (weft) and single strands for braids. Synthetic hair does not last as long as human hair because it gets quickly damaged from the sun.The quality of hair varies greatly, and if well maintained, synthetic hair can last up to a year. It will never look as human hair, as it is stiff and not bouncy at all. Synthetic hair is much less expensive than human hair.
No, we can’t. Heating appliances such as curling irons and straightening combs generally should never be used on synthetic hair. There are newer versions of synthetic hair from some brands that claim to allow styling with lower temperatures of heating appliances. Generally people should steer clear of such claims because the golden rule with synthetic hair is that heat is not an option. Synthetic hair is better used for shorter wigs. Typically when the synthetic hair is shaped it’s best not to change it, it is “What you see is what you get”.Synthetic Fibers are made from synthesized polymers or small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long, linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers. Although there are several different synthetic fibers, they generally have the same common properties.
There are several methods of manufacturing synthetic fibers but the most common is the Melt-Spinning Process. It involves heating the fiber until it begins to melt, then you must draw out the melt with tweezers as quickly as possible. The next step would be to draw the molecules by aligning them in a parallel arrangement. This brings the fibers closer together and allows them to crystallize and orient. Lastly, is Heat-Setting. This utilizes heat to permeate the shape and dimensions of the fabrics made from heat-sensitive fibers.
