Theorem — Hair Salons in Tempe | Book Online

We are a direct selling company that specializes in producing and developing our own line of high-end, bespoke hair care products. Theorem was developed by a brilliant team of scientists and designers with 75 years of combined experience, who have developed best-selling products with over a billion dollars in revenue sold worldwide. Disappointed with products on the shelf, we designed phenomenal formulas and packaging that finally met our standards. We started sharing them with friends and family, and they became so popular we had to start a full-scale production.
