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. Our Pure Plenty Nourishing Scalp Serum works to nourish the scalp from within. Pea sprout plant stem cells support a healthy hair cycle helping reduce the telogen hair phase (the phase of hair growth where resting hair remains in the follicle until it is pushed out by the growth of a new anagen hair.) Our powerful blend of Red Clover Tetrapeptide Complex inhibits DHT and helps improve root strength and may reduce visible damage caused by oxidative stress.
Half of men and 25% of women suffer from thinning hair.
Life realities like stress, nutrition, and age also make hair thinner.
Poor scalp health and circulation can slow and negatively impact a healthy hair cycle.
Pure Plenty three-step system uses innovative plant science to support density and reinstate hair’s lifeforce. To best results, follow all three steps: 1. Pure Plenty Shampoo, 2. Pure Plenty Conditioner, 3. Nourishing Scalp Serum.
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.
