Frequently asked questions
Our GreaterThan Hair Growth Shampoo is designed for all hair types, including those dealing with thinning hair or seeking enhanced scalp health. We use mild surfactants (cleansing agents that remove dirt, oil, and product build-up) and ingredients that strengthen and condition the hair. It is safe for color-treated hair and supports healthy hair growth.
There is no hard-and-fast rule here. This answer depends on your hair type and scalp conditions along with lifestyle and activities.
While this product is formulated for safe, gentle, daily use, we specifically chose not to call it a ‘daily shampoo’ because not every hair type is a candidate for daily shampooing. Individuals with very dry hair, coarse or textured hair, chemically-processed hair (e.g., straightened), or color-treated hair might not require daily shampooing. This product is safe for color-treated and damaged hair, and it actively promotes hair growth.
When it comes to lifestyle and activities, things like dry shampoo use, hair styling product use, sweaty workouts, and long-time hat wearing might tell you what frequency you need to wash your hair to keep your scalp and hair follicles clean and healthy.
We believe a thoughtfully-created, minimally-added fragrance enhances your product experience. Who doesn’t want a little close-your-eyes-spa-moment in the shower? Our GreaterThan Hair Growth Shampoo fragrance is made of all-natural ingredients, exists in less than 1% of our formulation, and features hair-supportive natural essential oils of lavender, eucalyptus, clary sage, and rosemary. These ingredients not only refresh your hair but also contribute to hair growth and scalp care.
Our GrowthFactor Formula™ is a collection of proven ingredients that activate hair growth, optimize the scalp, and defend against hair loss. The blend combines keratinocyte growth factor (KGF) and microalgae extract which both encourage growth and follicle health; a seaweed bioferment that is like a probiotic for your scalp; soothing, anti-inflammatory ancient herb gotu kola; and a DHT-inhibiting defense duo of saw palmetto and nettle root extract.
