Peptides, long celebrated in skincare, are now making waves in haircare—and for good reason. These small yet mighty molecules are quickly becoming the go-to ingredient for anyone seeking stronger, thicker, and healthier hair. But what exactly do peptides do for your hair, and why are products like The Ordinary’s Multi-Peptide Serum for Hair Density gaining so much buzz?
What Are Peptides and How Do They Work in Haircare?
Peptides are short chains of amino acids—the building blocks of proteins like keratin, which is essential for hair strength and structure. Thanks to their small size, peptides can penetrate the scalp more easily than larger proteins, reaching deep into hair follicles where they can make a real impact.
When applied to the scalp, peptides help:
- Stimulate Hair Growth: By encouraging blood flow and nutrient delivery to hair follicles, peptides can promote healthier, faster-growing hair.
- Strengthen Follicles: Peptides reinforce hair follicles, making them less prone to breakage and shedding.
- Boost Collagen Production: Collagen is vital for maintaining the health of hair follicles, and peptides can help increase its production, supporting stronger, fuller hair1.
- Reduce Inflammation: Certain peptides, such as copper peptides, help calm scalp inflammation—a common cause of hair thinning and loss—while also protecting follicles from oxidative stress.
Who Can Benefit from Peptides in Haircare?
The beauty of peptides is that they’re suitable for virtually all hair types. Whether you’re dealing with thinning, dryness, stress-related hair loss, or just want to boost your hair’s overall health, peptide-infused products can help. They’re especially beneficial for:
- Those experiencing hair loss or thinning (including post-stress or postpartum)
- Anyone with dry, damaged, or brittle hair
- People looking to improve scalp health and boost hair density
How to Incorporate Peptides Into Your Hair Routine
Ready to give your hair a peptide-powered boost? Here’s how to get started:

- Apply Consistently: For best results, apply your peptide product directly to the scalp (not just the hair shaft) and use it regularly—consistency is key to seeing improvement.
- Pair with a Healthy Routine: Combine peptides with a gentle shampoo, regular scalp massages, and a balanced diet to maximize benefits.
