The Science
The haircare industry rarely talks about its high markups, often replacing effective ingredients with water and paraben fillers to maximize profits.
Most serums, vitamins, and prescriptions fall short because they only target one or two factors of healthy hair growth—like stimulation or nourishment—while ignoring the rest.
Think of your hair as a factory, where follicles (the workers) need the right tools, materials, and environment to thrive. Ingredients like Biotin, Rosemary Oil, or Minoxidil play small roles, but no single solution addresses the full growth cycle or scalp health.
That’s where KYIR Fuller Active Serum comes in. With double the growth ingredients of competitors, our breakthrough Follicle Synergy System™ and patented Redensyl® formula target every angle—stimulating, nourishing, protecting, and balancing for visibly healthier, fuller hair.
Ingredients
After decades of experience and years of research, our science team has mastered formulating the most potent growth ingredients to work synergistically for maximum effectiveness.
Patented Redensyl®
A breakthrough patented Swiss formulated to help minimize hair loss and wake up hair stem cells to generate growth, Redensyl is a much better and more advanced alternative to its predecessor, Minoxidil. Redensyl has zero known negative side effects and is known to strengthen and thicken hair follicles and improve hair growth tremendously within 90 days of consistent use.
Follicusan
This proven topical hair loss treatment contains a blend of bioactive ingredients, including milk proteins, amino acids, and vitamins that help to increase hair growth and reduce hair loss, and protects the hair follicles from damage. Follicusan is designed to stimulate hair growth and reduce hair loss by activating the dermal papilla cells located at the base of the hair follicle, improving hair follicle function and growth.
Biotin
A well-known hair growth agent, Biotin helps to stimulate keratin production in hair and can increase the rate of follicle growth. Along with preventing hair loss, dandruff and itchy scalp, Biotin also strengthens hair follicles and adds shine.
Saw Palmetto
Native to the southeastern United States, this small palm tree has been used for centuries for its medicinal properties. Recently it has become increasingly popular as a natural hair loss treatment. Containing a number of active compounds, including fatty acids, sterols, and flavonoids that work together to help decrease the production of dihydrotestosterone (DHT), a hormone that can shrink hair follicles and lead to hair loss.
Ashwagandha
As a natural antioxidant with anti-inflammatory benefits, this potent herb helps to strengthen hair follicles and fight free radicals. Ashwagandha encourages the production of melanin in the hair follicle and aids to delay pre-mature greying. Its natural anti-inflammatory properties can help minimize scalp irritation and as a restorative effect on the hair follicle and scalp.
