Thinning hair is no different than aging skin or acne. If you stop using your anti-aging cream or acne treatment, your wrinkles and breakouts will gradually come back. The same goes for thinning hair. If you stop using our products, your hair will gradually make its way back to its starting point–unless something has changed inside your body as a result of other health and lifestyle changes. It’s important to stress that this process will be gradual. If you stop using Activating Serum, your hair won’t suddenly change the next day, week, or even month.
