There are constantly new ingredient innovations flooding the market and peptides have never been more talked about. But it’s not just the wellness space that is taking all the attention.
Driven by a growing appetite for ingredients that actually work at a cellular level, consumer interest in hair-specific peptides has exploded. They’re no longer just a skincare secret – they’re now one of the fastest-growing areas in hair health.
Search terms such as ‘GHK-Cu peptide’ are hitting ‘breakout’ status on Google Trends in Australia (as of mid-2026) while global search interest for ‘peptides’ in general has quadrupled over the past year according to Google Trends data.
This signals that consumers are treating haircare like skincare and demanding active ingredients to apply directly to the source. They do say that your scalp is an extension of your face, so why wouldn’t we treat it with the same care and attention?
Despite being hidden under our strands, scalp health plays a vital role in our overall hair health, including the condition, length and thickness of each strand. According to leading Sydney, trichologist Lena Hovardas “peptides are an exciting ingredient category because they may help support scalp and follicle health as part of an overall haircare routine”.
So, what exactly are peptides, and can they really make a difference to your hair?
Peptides, explained
Peptides are having a moment and for good reason. These short chains of amino acids act as the building blocks of key skin proteins such as collagen and elastin in skin. In hair, the logic follows a similar path: hair itself is primarily made up of keratin, a fibrous protein, and peptides play a role in supporting the structural integrity of each strand as well as enriching the scalp environment that hair grows from.
At the scalp level, these ‘personal trainers’ work quietly behind the scenes to signal cellular communication and encourage hair follicles to function optimally. This includes supporting the active growth phase of the hair cycle, improving overall follicle health and helping to maintain the conditions your scalp needs to grow stronger, more resilient hair over time.
While hair growth itself is influenced by a range of factors including age, hormones, stress, nutrition and genetics, healthy hair starts with a healthy scalp. And that’s where peptide-infused formulas are gaining attention.
“Peptides act as signalling molecules that can influence cellular communication within the scalp and around the hair follicle. Depending on the specific peptide, they may help support follicle function, improve scalp condition and reinforce proteins involved in hair structure and strength.” – Lena Hovardas, Trichologist
Who can benefit from peptides?
While peptides aren’t a miracle cure for hair loss, experts say they can play a supportive role in an overall healthy haircare routine, particularly when paired with nourishing ingredients that help minimise breakage and improve the condition of the scalp and hair fibre itself.
They may be especially relevant for those experiencing early thinning, increased breakage from styling, or slower growth cycles, but they’re equally suited to anyone looking to proactively support scalp health and stronger-feeling hair.
According to Lena, generally, “most peptide-based formulations are well tolerated across different hair types and age groups, although individual scalp sensitivities should always be considered”.
How to incorporate peptides into your haircare routine?
The good news? You don’t need a prescription or a clinical treatment to start exploring peptides for your hair. The new OGX ProGrowth+Peptide range has incorporated 9 per cent Long7vity Complex peptide technology into a four-step salon-quality system you can work into your wash day without overhauling your entire routine.
At the centre of the range is the Scalp Serum, that comes in a unique click pen designed to apply directly to root which helps strengthen, densify and reinforce the roots to support natural hair growth.
Using pisum sativum (pea) peptide, the range is designed to support healthier-looking, stronger-feeling hair, powered by a three-pronged approach. Firstly, caffeine and micro-algae feature in the scalp serum as the growth boosters, helping to encourage the root to stay active and inhibit hair thinning. Next, rice protein and panthenol in each product, structurally plump the hair strand, to reduce breakage and keeps things looking thicker. And finally, niacinamide and feverfew keeps the scalp ecosystem calm and healthy enough to sustain that growth.
As scalp-focused beauty continues to grow, peptides prove to be more than just another buzzy ingredient. They could become an important part of how we think about long-term hair health and with accessible options such as OGX ProGrowth + Peptide, it’s easier than ever to add to your shower shelf.
At OGX, we believe healthy hair gives you the confidence to boldly be yourself. Our high-performance, ingredient-led formulas help support hair health and resilience from root to tip, empowering you to wear your hair your way, every day.
