If you’ve spent any time researching hair growth, chances are you’ve come across the term GHK-Cu. It’s become one of the most talked-about molecules in the hair health world, appearing in everything from topical serums to injectable peptide discussions. But what exactly is GHK-Cu? Why has it generated so much excitement? And what inspired Evolv to create its own next-generation biomimetic technology, EV2 Peptide™?
Let’s break down the science.
GHK-Cu is a naturally occurring complex composed of the tripeptide GHK (glycyl-L-histidyl-L-lysine) and copper (Cu²⁺). One of the unique features of GHK is its dual functionality—it serves as both a signaling peptide and a carrier peptide, working together with copper to support healthy aging and the maintenance of healthy hair and skin.
GHK as a Signaling Peptide
As a signaling peptide, GHK helps coordinate the body's natural repair and renewal processes. Through its effects on cellular communication and gene expression, GHK supports the production of key structural components and helps maintain healthy skin, connective tissues, and hair follicles. GHK helps support these processes by:
Promoting collagen and extracellular matrix production for skin structure and resilience
Supporting tissue remodeling and cellular renewal
Helping maintain healthy skin, connective tissues, and hair follicles
Supporting balanced antioxidant and inflammatory responses
GHK as a Carrier Peptide for Copper (Cu²⁺)
GHK also serves as a carrier peptide for copper, delivering this essential trace mineral in a biologically available form. Copper acts as a critical cofactor for numerous enzymes involved in maintaining healthy tissues and protecting cells from oxidative stress. Copper serves as a critical cofactor for enzymes involved in:
Collagen cross-linking and structural integrity
Antioxidant defense against oxidative stress
Cellular energy production through mitochondrial enzymes
Maintaining a healthy scalp and hair follicle environment
Today, GHK-Cu is recognized as one of the world's most extensively studied copper peptides. Acting as a synergistic complex, it has attracted significant interest for its ability to support healthy aging, tissue renewal, collagen production, and skin structural integrity, while helping maintain resilient hair follicles and promoting healthy hair density, thickness, and overall vitality. Its antioxidant properties also help protect cells from oxidative stress, contributing to long-term hair and skin wellness.
Hair follicles are among the most biologically active structures in the body, constantly cycling through phases of growth, rest, and renewal. To maintain healthy hair growth, follicles rely on several key processes, including structural support, cellular energy, nutrient delivery, balanced signaling, and a healthy growth environment.
Hair Strength & Structure – Supporting collagen production and the structural framework that surrounds and anchors hair follicles.
Cellular Energy – Helping fuel the highly active cells involved in healthy hair growth.
Nutrient Delivery – Supporting the supply of oxygen and nutrients needed by growing hair follicles.
Healthy Growth Cycles – Helping maintain the natural signaling pathways associated with normal hair follicle function.
A Healthy Growth Environment – Providing antioxidant support to help maintain a healthy scalp and promote thicker, fuller-looking hair.
Researchers have observed that GHK-Cu helps support many of these biological processes simultaneously. While no single ingredient can solve every cause of hair thinning, GHK-Cu has emerged as one of the most intriguing compounds in modern hair biology.
As interest in GHK-Cu has grown, so have the ways people try to use it.
Many hair serums and scalp treatments contain copper peptides. The advantage is direct scalp application. The limitation is that topical products primarily support localized exposure and often depend on formulation quality, consistency of use, and scalp penetration.
While injection can deliver systemic exposure, it also introduces complexity, cost, inconvenience, quality and regulatory considerations that make them impractical for most people.
Historically, oral delivery has been one of the biggest challenges in peptide science. Peptides can be broken down during digestion before reaching their intended destination.
At Evolv, we believed there had to be a better way.
When tissues are injured, naturally occurring GHK fragments are believed to be released from collagen. These fragments act as biological messengers, signaling fibroblasts to produce collagen, elastin, and other structural molecules needed for tissue repair and regeneration. Simultaneously, GHK binds copper and delivers this essential trace mineral to support the enzymes responsible for collagen maturation and antioxidant defense. Because free copper ions are difficult to transport and can be unstable, chelation by GHK helps provide copper in a stable, biologically available form where it is needed most. Together, these complementary functions make GHK-Cu a remarkable example of nature's own "signal-and-deliver" system for maintaining healthy tissues, skin, and hair follicles.
Inspired by this underlying biology, we asked a simple question: What if we could create an oral biomimetic platform inspired by the biology of GHK-Cu?
Bioactive copper in the form of copper gluconate, a biologically available source of this essential trace element;
Marine collagen-derived peptides, inspired by the natural origin of GHK within collagen;
A proprietary oral delivery architecture designed to enhance peptide stability, support systemic biological signaling, and promote the efficient delivery of bioavailable copper.
Together, these components create a biomimetic copper-peptide environment designed to support healthy hair follicle function and the biological processes associated with naturally occurring GHK-Cu activity.
One of the limitations of many hair products is that they focus exclusively on the scalp. But hair growth starts much deeper. Healthy follicles rely on systemic biological processes involving:
Cellular Renewal – Supporting the continuous turnover and regeneration of follicular cells.
Structural Protein Production – Maintaining the collagen-rich extracellular matrix that supports healthy follicles.
Nutrient Delivery – Ensuring an adequate supply of oxygen, copper, and other essential nutrients to actively growing follicles.
Growth-Phase Maintenance – Helping sustain the biological signaling pathways involved in normal hair cycling.
Follicular Resilience – Supporting antioxidant defenses and maintaining a healthy environment for long-term follicle function.
EV2 Peptide™ was specifically designed to support these pathways from within through daily oral delivery. By combining copper-peptide biology with a convenient oral format, Evolv Grow helps support:
Hair Density – Helps support fuller-looking hair by nourishing healthy hair follicles with a blend of copper-peptide-inspired nutrients, spermidine, and targeted botanical extracts.
Hair Thickness – Provides key structural nutrients, including marine collagen peptides and silica-rich horsetail extract, to support thicker, more resilient hair.
Hair Strength – Delivers bioavailable copper and marine collagen peptides to help maintain strong, healthy hair fibers from within.
Reduced Shedding – Supports healthy hair growth cycles with targeted ingredients, including saw palmetto fruit extract for men and pea shoot extract for women, helping maintain naturally fuller-looking hair.
Overall Hair Quality & Appearance – Combines nicotinamide riboside chloride, spermidine, marine collagen peptides, and bioavailable copper to help promote healthy-looking, vibrant hair.
Both Evolv Grow for her and Evolv Grow for him are built on the same EV2 Peptide™ foundation. More than 95% of the formulation is identical between the two products. The difference lies in a single targeted ingredient chosen to support the unique biological environments associated with female and male hair thinning.
Evolv Grow for her includes Pea Shoot Extract (Pisum sativum), selected to support healthy hair cycling and help maintain follicles in an active growth phase for longer.
Evolv Grow for him includes Saw Palmetto Extract (Serenoa repens), selected to support pathways associated with androgen-sensitive hair biology and a healthier follicular environment.
GHK-Cu helped inspire an entire generation of hair growth innovation. At Evolv, we took that inspiration and built something new.
Rather than creating another topical serum or relying on injections, we developed EV2 Peptide™, a proprietary oral biomimetic technology designed to support copper-peptide biology from within.
The result is Evolv Grow—a science-first approach to hair health that combines bioactive copper, marine collagen-derived peptides, and our proprietary Cu Peptide Mimetic™ platform to support thicker, fuller, healthier-looking hair over time.
Because healthy hair doesn’t start on your scalp.
It starts with the biology beneath it.
