Advanced Hair Serum Formula to Strengthen Hair, Boost Density & Slow Hair Aging
CONDITIONER ISN'T ENOUGH FOR YOUR HAIR & SCALP
When it comes to thinning hair and scalp aging, regular shampoos and conditioners will only take you so far. When the problem runs deeper than surface-level dryness, only a fully targeted treatment can restore hair density by working on the deepest levels of the scalp and follicle. Our Collagen Hair Renewal Serum is specifically formulated to target these root causes with precision, using clinically proven actives to revive dormant follicles and strengthen hair from within.
A HIGHLY CONCENTRATED SERUM SCIENTIFICALLY DESIGNED TO "REVIVE" HAIR FROM ROOT TO TIP
Our Hair Renewal Serum has been carefully formulated by top-tier trichologists and cosmetic biologists to visibly restore hair density, strength, and shine. It is designed to reactivate sleeping follicles, extend growth cycles, and create optimal scalp conditions for healthy hair production. As a result of this 3-in-1 hair revival effect, your hair becomes thicker, stronger, and significantly more vibrant-looking.
Here's how it works:
The serum contains a high concentration of KERASCALP™, a potent scalp rejuvenator derived from 100% natural Amla extract. This powerful active is scientifically acclaimed for its ability to stimulate Collagen XVII production and preserve scalp stem cells. When the serum is applied, KERASCALP™ penetrates deeply into the scalp, restoring the biological integrity of each follicle and creating visibly stronger, darker hair within weeks.
THICKER HAIR, HEALTHIER SCALP OVER TIME
Beyond reviving dormant follicles, our Collagen Hair Renewal Serum offers extensive long-term benefits for your hair and scalp through its potent ingredients: BAICAPIL™, KERARICE™, and KERACYN™.
- BAICAPIL™ switches your hair follicles from resting phase to active growth phase, extending growth cycles by 68.6%. Over time, you can expect visibly thicker hair with 22% more density and 60% less shedding.
- KERARICE™ acts like sunscreen for your hair, shielding it from UV damage while repairing past damage to keratin proteins. By restoring 48.1% of UV-degraded proteins, it prevents color fading and maintains hair's natural strength and brilliance.
- KERACYN™ seals the hair cuticle to lock in moisture and prevent protein breakdown. This innovative extract keeps your hair smooth, elastic, and visibly shiny while protecting against environmental damage.
This rare combination of these advanced ingredients ensures your hair not only looks thicker immediately due to follicle reactivation, but also becomes healthier over time. With consistent use, you can expect substantial improvements in hair density, reduced graying, increased shine, and a vibrant, youthful appearance.

Science
TARGETING THE ROOT CAUSE OF HAIR AGING
Hair thinning and aging form primarily due to the natural aging process, which significantly impacts the scalp's structure. Collagen XVII, a critical structural protein, provides hair follicles with stability and anchoring. The problem is that over time, the scalp's collagen production sharply decreases. By the age of 35, scalp collagen reserves begin to dwindle, and hair growth cycles become progressively shorter. This loss of collagen weakens the follicle's support system, causing it to shrink and produce thinner, weaker hair.
Other factors that contribute to hair aging include environmental damage (such as UV radiation and pollution), lifestyle choices (like poor nutrition and stress), and hormonal changes. These elements accelerate collagen breakdown in the scalp and reduce the follicle's ability to maintain healthy hair production, resulting in more visible thinning and premature graying.
HOW OUR SERUM WORKS
Our Collagen Hair Renewal Serum is designed to combat these effects through a sophisticated blend of ingredients:
- KERASCALP™: Stimulates Collagen XVII production and preserves scalp stem cells, targeting the biological root of hair aging and preventing premature graying.
- BAICAPIL™: Reactivates dormant follicles by switching them from resting phase to active growth phase, extending hair growth cycles and increasing visible density.
- KERARICE™: Shields hair from UV damage and restores damaged keratin proteins, protecting hair structure and preventing color fading.
- KERACYN™: Seals the hair cuticle and prevents protein breakdown, maintaining hair shine, elasticity, and strength.
These powerful ingredients work together to reactivate sleeping follicles and restore scalp health, promoting thicker, stronger hair both immediately and over the long term. By targeting the root causes of hair aging, our serum provides comprehensive hair care, ensuring your hair remains dense and youthful.
