What's Inside
The pure, active ingredients your hair actually needs.
01
Capilia Longa™
A potent ingredient from plant stem cell technology, bio-engineered to combat hair loss. Studies show up to 89% less hair loss, an average of 13,500 new hairs, and a 52% boost in hair density.
Stimulate
02
Elaya Renova™
Derived from olive tree stem cells, this powerful ingredient works to reinforce the hair strand to its follicle and increase its diameter. Studies have shown up to a 44% increase in hair diameter, 78% increase in hair strength, and 28% increase in hair density.
Fortifies
03
Caffeine
Derived from coffee plants, caffeine is a powerful ingredient that works to stimulate hair follicles and block DHT (the hormone responsible for hair loss). Research shows that caffeine penetrates the scalp quickly, extends the hair growth phase, and improves blood circulation to follicles. When applied regularly, caffeine helps strengthen existing strands while promoting the development of thicker, more resilient hair.
Anti-oxidizes
04
Rosemary Oil
Derived from the flowering herb Rosmarinus officinalis, rosemary oil is a potent extract that works to enhance scalp circulation and block DHT from binding to hair follicles. Research shows that rosemary oil stimulates cellular metabolism at the root while promoting thicker, stronger hair growth when applied consistently.
Volumizes
05
Saw Palmetto
Saw Palmetto reduces DHT production, aiding in preventing hair loss and promoting hair growth. It also contains fatty acids and phytosterols, nourishing and soothing the scalp, making it conducive to healthy hair growth.
Protects
06
Pumpkin Seed Oil
Derived from cold-pressed pumpkin seeds, this nutrient-rich oil works to naturally inhibit 5-alpha-reductase, the enzyme that converts testosterone to hair-damaging DHT. Research shows pumpkin seed oil delivers essential fatty acids and antioxidants directly to follicles, supporting existing hair while encouraging new growth.

If you're a guy in your 20s already seeing recession, get this NOW. Wish I started earlier. Been using for 5 months and my temple points are actually coming back. The earlier you start, the better it works.
