Frequently Asked Questions
Like any good wellness routine, results require effort to be maintained. If you stop using GRO Hair Serum, you'll see hair return to its natural state within a few months of discontinuing use.
HYDR-8 Weightless Repair Oil is a styling treatment and finishing hair oil so we recommend using it on damp hair or dry hair instead of an overnight treatment.
There is no right or wrong answer. It’s really a personal question and depends on scalp sebum production (oily or dry) and hair density (thick or thin) as well as hair texture.
