Frequently asked questions
Our shampoo is designed for all hair types. 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.
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; styled hair (e.g., braided); chemically-processed hair (e.g., straightened); or color-treated hair might not require daily shampooing. This product is safe for color-treated hair.
When it comes to lifestyle and activities, things like dry shampoo use, hair styling product use, or sweaty workouts, and long-time hat wearing might tell you what frequency you need to wash your hair to keep your hair and follicles clean.
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 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.
Our GrowthFactor Formula™ is a collection of proven ingredients that activate growth, optimize the scalp, and defend against 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.
