The History of Joico

During the early years, Joico was looking for a way to create hair care that delivered the most effective reconstructive process. Although the company began with a formula using nucleic acids for reconstruction, within one year another important discovery occurred that would forever change the hair care industry. Joico’s scientists discovered how Human Hair Keratin Protein could be captured and used to truly rebuild hair. For the first time in history, Joico began using Human Hair Keratin Protein (HHKP) in all of its products to strengthen and rebuild hair with a benefit that went beyond simply offering a cosmetic or temporary feel to the hair.

Using Human Hair Keratin Protein made sense. Because hair needed to be rebuilt with all of the 19 amino acids found naturally in hair, hydrolyzed human hair was the only option to achieve this result. Joico began to acquire HHKP from different sources only to find that researchers were discovering new ways to improve on the formula. Joico took great pride in offering the finest quality products with the best possible results. At the time, HHKP had a molecular weight and size of 150-300. Although Joico now uses a wider range of molecular weights, it was a great start to a journey committed to the art of perfecting healthy hair.

Joico continued its journey as a leader on the forefront of reconstructive hair technology. Once again, science discovered a way to make the original formula more effective, and Joico wasted no time in utilizing this new technology. Researchers proved that HHKP could be processed into MWS of 150-1800 with even more effective and quicker reconstruction results than the original formula.
