Peptides have become one of the most talked-about ingredients in the beauty world, largely because of how versatile they are and how many different ways they can be used in skincare and haircare formulas. In recent years, their popularity has expanded beyond facial treatments and into scalp and hair-growth products, where brands and experts are exploring how these powerful molecules may support healthier, fuller hair.

Why Peptides Are Trending Beyond Skincare
Peptides are not only trending in skincare; they also appear frequently in online discussions around muscle building, weight management and other performance-related topics. Social media platforms like TikTok have contributed to the surge in interest, although some discussions—especially those linked to extreme appearance-focused trends—can be misleading or problematic.
What Peptides Actually Do in the Body
In biological terms, peptides are short chains of amino acids that perform multiple functions throughout the body. They often act as signalling molecules, helping cells communicate with each other. When used in skincare, peptides can encourage the skin to produce more collagen and elastin, which may help improve firmness and reduce the appearance of fine lines. The body naturally produces thousands of different peptides, each with its own unique role in health, repair and healing processes.
Peptides and Their Potential Benefits for Hair Growth
Scientists and hair specialists are also investigating certain peptides for their ability to support healthier hair growth. According to Dr Munir Somji, hair-growth peptides are specifically designed chains of amino acids that send supportive signals to hair follicles. These signals may stimulate follicle activity, enhance scalp health and encourage stronger hair strands.
How Hair Growth Peptides Work
Hair-growth peptides primarily target the follicle and the surrounding scalp environment. Their role is not to create brand-new follicles but to optimise the performance of the follicles that already exist. By improving the health of the scalp and supporting follicle function, these peptides may help hair grow thicker and appear denser over time. In simple terms, they act like messengers that guide existing hair structures to function more efficiently.
Expert Insights on Peptides for Hair Growth
To better understand how peptides work in haircare, hair restoration surgeon Dr Somji, cosmetic doctor Dr Bhavik Shah and trichologist Anabel Kingsley have shared their insights on the subject. They discuss common questions such as how peptides compare with treatments like minoxidil or finasteride, how long it takes to notice results, whether continuous use is necessary, and whether peptide products can safely be combined with treatments like PRP therapy or microneedling.
Vogue-Recommended Peptide Hair Products
One of the standout products is The Ordinary Multi-Peptide Serum For Hair Density. Originally known for skincare peptides that support collagen and elastin production, the formula adapts similar technology for the scalp. When applied regularly, it may help create the appearance of fuller hair. The formula also includes caffeine to improve scalp circulation, allowing more nutrients to reach the roots.
Typebea G1 Overnight Boosting Peptide Serum
Typebea’s G1 Overnight Boosting Peptide Serum comes in a larger bottle designed for long-term use during a hair-growth routine. The serum focuses on scalp hydration, itch relief and follicle support through a blend of smart peptides and gentle exfoliating ingredients such as lactic acid and gluconolactone. Many users report positive results, including improvements in postpartum hair shedding. Its lightweight, fast-absorbing texture also makes it suitable for both morning and nighttime application.
Scandinavian Biolabs Bio-Pilixin Activation Serum
Another product highlighted by Vogue is the Scandinavian Biolabs Bio-Pilixin Activation Serum. This formula includes ingredients like niacinamide and caffeine, which help stimulate blood circulation in the scalp—an important factor for healthy follicle activity. The serum also contains plant growth factors and turmeric extract to reduce inflammation, which is often linked to hair thinning.
Scientific Evidence Behind Peptide Hair Treatments
According to experts, the ingredients in this formula may help extend the anagen phase, which is the active growth stage of the hair cycle. Clinical testing has suggested promising outcomes. In one trial, participants experienced reduced hair shedding and increased hair density after approximately 150 days of use. These findings highlight the growing scientific interest in peptides as part of modern hair-care routines.
