Redensyl® – 2%

Redensyl® stimulates hair growth, reduces hair fall, and increases hair density. Clinical studies have shown significant improvement in hair density and strength within 84 days of use.

Scientific Role of Redensyl

Hair Growth Stimulation

Redensyl® targets hair follicle stem cells and dermal papilla cells, key players in hair growth. It enhances stem cell proliferation and prevents apoptosis (cell death) of these cells, leading to healthier, denser hair.

Reduction of Hair Fall

Clinical studies showed that Redensyl reduced hair fall by up to 17% after 3 months of use. The product reactivated hair follicle stem cells and improved hair anchorage, significantly reducing daily hair loss.

Improvement in Hair Density

Redensyl demonstrated a +8% increase in hair density and a +9% increase in hair thickness after 3 months. Volunteers experienced visibly fuller hair, with over 85% showing positive results in clinical evaluations.

Real Results, Backed by Science

  • Decreased skin irritation by 21%
  • Increased hair growth by 214%
  • New anagen hair growth by 9% to 20% in different age categories by 10.8% to 19.2% to 9.2%
  • Increased hair density by 17%
  • +10,200 hair on average in 3 months: better results than one hair transplantation procedure
  • Anti-hair loss, stimulation of hair growth, re-densification of hair on scalp.

Burgeon Up – 2% (Nasturtium Officinale Leaf/Stem Extract)

BURGEON-UP is a plant-based hair care ingredient made from fresh watercress grown in Japan. What makes it special is R-spondin 1, a powerful protein that activates the roots of your hair follicles to spark visible hair growth.

INCI: Nasturtium Officinale Leaf/Stem Extract
Part used: Leaf and stem
Country of origin: Japan
Use: Hair growth, scalp health, hair loss prevention
Blending amount: 2% recommended

What It Does

BURGEON-UP works at a deep, cellular level to help bring thinning or weakened hair back to life. The secret? R-spondin 1, a protein known in regenerative medicine for its role in tissue repair. In hair science, it’s proven to activate outer root sheath cells—the foundation of hair follicles responsible for making thick, strong hair.

Benefits of BURGEON-UP
  • Promotes natural production of R-spondin 1
  • Activates dormant hair follicles and protects growing ones
  • Suppresses DKK1, a hair loss factor linked to male hormone imbalance
  • Boosts hair thickness, growth rate, and strand count
  • Effective for both male and female pattern hair loss
Award-Winning Ingredient
  • Finalist, in-cosmetics Asia 2019 – Best Ingredient
  • BSB Innovation Award 2020, 2nd Prize – Hair & Scalp Care

Real Results, Backed by Science

In vitro studies (on human dermal papilla cells):

  • Increased R-spondin 1 secretion at 0.5–1% concentration
  • Suppressed DKK1 and IL-6, both linked to hair thinning caused by male hormones (DHT)

Ex vivo tests (on cultured human hair follicles):

  • Follicles treated with 1% BURGEON-UP showed longer growth over 5 days

Capilia Longa™ – 1% (Turmeric Root Stem Cells)

Capilia Longa is a high-performance ingredient made from turmeric plant stem cells. It’s designed to wake up tired hair follicles, reduce hair fall, and bring back fuller-looking hair naturally.

What it does

This smart botanical ingredient works at the root level. It helps reactivate dormant hair follicles and provides them with the boost they need to start growing stronger, healthier strands. Think of it like a reset button for your scalp.

Where it’s from

Capilia Longa is made in Spain using a patented technology that extracts the most active parts of the turmeric plant. It’s clean, plant-based, and backed by biotech.

Why It Works

Capilia Longa encourages your scalp to produce the same growth signals it did when your hair was at its best. It supports the natural cycle of hair growth, making it easier for more hair to remain in the growth phase for longer.

  • Boosts natural growth signals in your scalp
  • Reactivates hair follicles that have stopped producing new strands
  • Helps reduce hair thinning and visible hair loss
  • Promotes thicker, denser, and healthier-looking hair
Real Results, Backed by Science
  • In a 150-day study, it reduced hair loss by up to 89%
  • Increased hair density by up to 52%
  • Boosted the activity of key growth factors like VEGF, HGF, and FGF7 that are essential for hair regeneration
  • Safe for regular use—non-irritant, hypoallergenic, and gentle on skin

How does this work?

  • Tells weak hair to toughen up and start growing, no quitters allowed.
  • Bulks up your strands so you’re not left with wispy little baby hairs.
  •  Keeps your scalp locked and loaded, so your hair stays where it damn well belongs.

THE COCKY Way to Do It Right

Drop it like it’s hot, straight onto your roots (or your beard, no judgment here)! Massage in a few drops and let it work its magic. Your hair will start looking thick, healthy, and ready to turn heads. Oh, and your beard? It’s about to get some serious love too, because why should your face miss out on all the good stuff?

    I’ve never been big on skincare, but this face wash is really something. Quick, easy, and does a great job. Cleans my face well without drying it out, and it’s helped reduce some of the acne I used to get. Loving the woody smell too.

    hmmm I was losing hair, and a lot of them. It was everywhere, on my pillow, in the shower, you name it. Tried the Cocky Hair Serum after seeing an ad, and I’ve actually started to see a difference. There’s definitely less hair fall, and my hair feels stronger, been about 1 month or so. I am hoping in 3-4 month should make a big impact.
