How does FolliBoost Hair Regrowth Spray work? FolliBoost Hair Regrowth Spray is a hair growth accelerator and preventer. FolliBoost keeps the scalp healthy, strong and nourished. All natural grapefruit and orange extracts penatrates deep into the hair follicles, stimulates enzyme activities, increases absorption of nutrients and restores balance to the damaged hair follicles. This balanced scalp environment allows for healthier, stronger and more resilient hair growth. FolliBoost promotes successful therapy at the root cause of premature hair loss making it much more effective than any topical treatment or over-the-counter product that simply treats the surface of your scalp, which can add to dryness of your hair and scalp.
