Apply to wet hair using the applicator, or dispense a nickel-sized amount into your palms and massage into scalp and hair. Allow product to work for a minute before rinsing out.

Super-natural Results.

Pure Plenty is designed to revitalize the scalp and strands. Perfect for anyone with fine or thinning hair who strives for a full, lush head of hair, our 3-product regimen uses the antioxdant powerhouse of plant stem cells to regenerate and protect the skin and hair from stress and damage. Our potent plant bioactives ingredients deliver scalp to strand nutrients that support a healthy hair cycle. The gentle exfoliating shampoo gently clears away buildup, opening and stimulating the hair follicles for optimum growth and movement. It is free of silicones and other synthetic ingredients that can create toxic accumulation and prevent proper absorption of any therapeutic product. A combination of plant-stimulating agents adds extra body and volume. Nettle helps clear the scalp & improve hair shine. Pea sprout plant stem cells and red clover peptide complex inhibit DHT (a primary cause of thinning hair & hair loss) as well as promote healthy follicles. Decyl Glucoside, a sugar-derived mild cleansing agent, provides a quick cleansing foam.

Intelli-Cell™ Science.

Our pea sprout plant stem cells which are grown in the lab, not on land through conventional farming methods, which makes for a more sustainable production process. This revolutionary bio tech process delivers up to 1000x the antioxidant potency of conventionally harvested plant ingredient actives. Lab cultivation versus farming means saving a huge volume of water as irrigation is not needed, preserving land for growing food and providing access to rare plant species and their benefits using just 1 plant vs. tens of thousands. All to create groundbreaking active plant-based ingredients responsibly. Always non-GMO and without the use of pesticides, fungicides or herbicides. The plant stem cell strain is kept in cryogenic state and replaced every 3 years using only 1 plant.
Get to the Root.
Build-up of residue from other product lines, environmental and water pollutants on hair shaft and scalp can harden, create toxic accumulation and prevent proper absorption of any therapeutic product. Our nozzle applicator gets cleansing to the scalp helping reduce this common build-up.

How it Works

Health hair starts at the root. Our system supports root strength and improves the ratio of anogen (growth phase) to telogen (resting phase) of the hair cycle for denser, fuller-looking hair. Normal hair follicles are surrounded by healthy connective tissue and dermal papilla, and have minimal oxidative stress. Hair loss occurs most often when the hair growth cycle is disrupted by an increase of dihydrotestosterone (DHT) hormone, loss of connective tissue integrity surrounding the hair follicle, and/or an increase of the inflammatory process and oxidative stress in the scalp. With age, the decreased number and size of hair follicles in the scalp will also lead to thinner hair and an increase in hair loss.
Removes build-up and jumpstarts follicles.
A combination of plant stimulating agents adds extra body and volume.
The proof is in the poof.
Essential oils/flavors of geranium, jasmine, mandarin peel, bergamot, vetiver, root and may chang fruit help the scalp stay balanced, hydrated and supple; while providing calming, uplifting and grounding benefits for the senses.

Consumers Say
"Perfect amount of micro suds. Genius packaging. Makes my hair feel light, airy, perfectly conditioned, and super soft, all at the same time. On my 20th bottle at least, and every other shampoo is just awful in comparison. Don’t ever stop making this shampoo!"
