Hair and compounds is an international company based in the United States. The company has established an extensive network to gather hair from all around the world to be used as hair extensions. The gathered hair is used in Hollywood productions as well as theatre productions, and even purchased by beauty salons for resale to retail customers.  When Hair and Compounds receives new samples of hair it tests that hair to measure for moisture content, strength, surface energy, and elasticity. These are the factors that determine the true quality of the collected hair samples. Once the test are completed the hair goes through manufacturing process which includes hand making of wefts and other techniques so the hair can be attached flawlessly to a person’s own hair to make it look natural. The extensions last for a minimum of 3 months and can be used for a year or more as long as it is properly maintained.
