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.
Does this contain CBD?
Unlike the prior formula, the new GRO+ Advanced Hair Serum does not contain CBD. Instead, GRO+ Advanced Hair Serum features Spanish Microalgae, a prebiotic superfood that hydrates to balance the scalp and support a healthy skin barrier.
