Frequently asked questions
Root Source® is a two-capsule system designed to work holistically to deliver hair renewal & growth at the source. Capsule 1 lays the foundation with a customized blend of actives known to balance the scalp*. Capsule 2, containing our proprietary PureCatalyst™ complex, stimulates the hair bulb for faster hair growth and decreased shedding*.
To ensure the best results, Root Source® is only available for purchase as a two-capsule system.
Take your two Root Source® capsules once a day, with food if you have a sensitive stomach. Consistency is key, so aim to take daily without skipping any doses.
Totally normal—Root Source® is made without any synthetic fillers or dyes, so what you’re seeing is natural. The actives may separate into their crystalline forms, making spots of the capsule appear cloudy, but this has no impact on the formulas’ freshness or potency.
Within a few weeks of use, your scalp should feel more balanced and hair should start feeling softer and stronger. After three months of use, you may notice new baby hairs forming; stay committed, and after six months you’ll continue to see the results of new hair growth*. Results may vary.
If for any reason you’re not completely satisfied with the results of your Root Source® supplements, you can contact The Pros.
All Root Source® supplements are vegan, cruelty-free, and gluten-free through the use of gluten-free wheat extract. In addition, they are free of the following: soy, nuts, GMOs, hormone disruptors, synthetic fillers, artificial flavors, and artificial coloring.
You can view a full list of your Root Source® ingredients in your shopping cart before checkout, but please note that we cannot add or remove ingredients from your formulas.
