*Hormone-Free: Our Level 1 and Level 2 Kits are completely hormone-free and result in natural regrowth by restoring the scalp, follicles, and sebaceous glands to a healthy state. Most of our clients experience sufficient regrowth at Level 1 and Level 2 but some clients may require Level 3 containing the hormone Minoxidil which is FDA-approved to grow hair. Hair growth claims refer to Level 3 kits which contain Minoxidil, but natural regrowth is the result of good scalp restoration and hygiene.
