Manufactures warrenties are void more often then you may think. If you are not using a digital scale, if you process your color even 1 minute longer than directed, etc, it is no longer valid Olaplex works independently of color and does not affect the color chemistry. The color manufacturer would be responsible for any defect in color. We have never heard of an actual case of any color manufacturer defending a colorist or assisting in any legal issues. You should research this topic.
Insurance companies also don't guarantee protection. We educate stylists that Olaplex is only and insurance and to use good judgment, so If a stylist fails to do this, this will be on them not on their insurance company.
