Frequently asked questions

What is the GrowthFactor Formula™?

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.

What hair type is this shampoo good for? Is it color-safe?

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.

What hair type is this conditioner good for? Is it color-safe?

Our conditioner is designed for all hair types. We use mild conditioning agents to treat, smooth, protect, and tame the hair. It is safe for color-treated hair.

When do I use the serum and when will I see results?

The serum is meant to be used once a day. Most people start to see small hairs and densifying after three months of consistent use. Consistency is absolutely key – you’ll want to feed your follicles this serum on a daily basis, either in the morning or night, whatever works best for your routine.

When do I use the scalp treatment and what does it do?

The scalp treatment is designed to be used once or twice a week. Think about it like a deep cleaning for your follicles, which get clogged with hair product, sweat, oil, and the general debris of our environment. The gentle acids in here give your roots a reset to pave the way for new growth. Follow the instructions on the packaging for precise usage.
