Theorem Hair is a 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 female scientists and designers with 75 years of combined experience, who 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. 

We pride ourselves in the simplicity of our business model. We formulate, test, package, market and manufacture our products under one wholesome, family-owned roof. By taking control of every part of the business, we can provide increased transparency and a more effective product for the price. 

 We have our own private R&D team, our own lab, and our own manufacturing plant. With over 25 years in manufacturing, we make all Theorem formulas ourselves, in our Chicago-based, family-owned facility. We have first access to the latest clinical studies and ingredients so we are always one step ahead of the pack. 

Heavily rooted in R&D, you could say our team geeks out about hair care. Each product is hand-crafted to incorporate proven science. Every formula is perfectly pH balanced to promote a healthy root, strand and tip. We've reviewed thousands of clinical studies and worked on 10's of thousands of formulations throughout our careers. Theorem is a culmination of the most promising data of our combined lifetimes. 

Our dream is to help people increase confidence and restore their own hair. Our custom formulas are designed to strengthen and thicken each strand. Our product development process if fueled by friends and family. Each formula is passed out to friends and family for feedback and revised based on everyone's personal experience. We took time to get the formulas right and as a result we have built a cult following.
