FREQUENTLY ASKED QUESTIONS

How soon can I expect to see results?

When applied daily, expect to see results from GRO+ Advanced Hair Serum in 3-4 months. Our best advice: Consistency is key. Using daily is essential to seeing a visible improvement.

Will it make my hair greasy?

No! The formula is lightweight, fast-absorbing and water-based. It can be applied to wet or dry hair without disturbing your style. In a 120-day consumer perception study of individuals using GRO+ Advanced Hair Serum daily, 98% of participants agreed the product did not make their scalp feel greasy.

What is the difference between GRO+ Advanced Hair Serum and GRO Hair Serum?

GRO Hair Serum is a great option for those who are looking for a proactive approach to hair wellness or are starting to see early signs of shedding. Those with moderate to severe shedding or scalp concerns are best suited to use GRO+ Advanced Hair Serum, our most advanced formula yet.
