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™?
In order to understand Evolv Grow, we need to first understand GHK-Cu and its role in our biology.
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.
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 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 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.
Inspired by this remarkable peptide, we built our own oral, bioavailable, biomimetic platform that functions similarly to GHK-Cu in the body: EV2 Peptide™, and our proprietary Cu Peptide Mimetic™. EV2 Peptide™ combines:
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 designed to support healthy hair follicle function and the biological processes associated with naturally occurring GHK-Cu activity.
Evolv Grow supports:
Hair Density – Helps support fuller-looking hair by nourishing healthy hair follicles.
Hair Thickness – Provides key structural nutrients to support thicker, more resilient hair.
Hair Strength – Peptide-mimicking technology helps maintain strong, healthy hair fibers from within.
Reduced Shedding – Supports healthy hair growth cycles helping maintain naturally fuller-looking hair.
Overall Hair Quality & Appearance – Helps 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 novel.
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.
Because healthy hair doesn’t start on your scalp. It starts with the biology beneath it.
Learn how GHK-Cu became one of the most studied molecules in hair science, and how Evolv's proprietary EV2 Peptide™ technology was inspired by its biology to support healthy hair growth through a next-generation oral biomimetic approach.
Biomimetics represent a new era in hair science—supporting the body's natural follicle signaling pathways rather than simply supplying nutrients, helping create a smarter, more biologically aligned approach to healthy hair growth.
GHK-Cu is one of the most studied peptides in hair health, and its biology inspired EV2 Peptide™—our proprietary oral biomimetic technology designed to support healthier, fuller-looking hair from within.
