Our Key Ingredients

Organic Caffeine Extract

To Multiply And Lengthen Hair

Our caffeine is derived from organic, eco-conscious sources to ensure purity and sustainability. It stimulates microcirculation in the scalp, delivering essential oxygen and nutrients to hair follicles. This process supports healthy growth cycles, revitalizing the scalp. Additionally, caffeine strengthens hair at the root, improving its resilience and promoting a visibly denser, shinier appearance with regular use.

Raw Niacinamide (Vitamin B3)

Nature's Hydration Blueprint

Niacinamide is a powerful vitamin that restores the scalp’s natural hydration barrier, reducing dryness and irritation. It promotes a balanced, healthy scalp environment by supporting cellular renewal and improving resilience to external stressors. With consistent use, niacinamide enhances hair shine, softness, and overall vibrancy, creating the perfect foundation for untamed growth.

Botanical Rice Extract

Strengthen From Root To Tip

Our rice extract and amino acids are derived from nature’s most nutrient-rich grains. These botanicals repair and fortify hair fibers, strengthening strands and reducing breakage. By replenishing essential proteins, they enhance hair’s elasticity, smoothness, and natural shine, leaving it healthier and stronger with each use.

Organic Aloe Vera Leaf Juice

Mother Nature's Moisturiser

Our aloe vera is sustainably harvested to retain its rich blend of vitamins, antioxidants, and amino acids. Known for its soothing properties, it calms the scalp while giving your hair strands the deep hydration it needs. This botanical elixir restores balance, reduces dryness, and enhances softness and shine, leaving hair feeling silky and revitalized from root to tip.

    Less fall out, thicker feeling hair

    It's expensive but you get what you pay for. I've been using this for about 11 months and I have to say that my thinning hair feels thicker AND there is not too much fall out in the shower. I do still have some, but it's half of what it was. I highly recommend it.

    My Hair Is Muliplying :)

    Been using it for minor stress related hair loss in addition having to fine hair. The most noticeable difference is that my baby hairs around the bangs area definitely grow in faster.
