You might have seen the term on social media in connection with peptide stacking for building muscle, losing weight, or the more dangerous “looksmaxxing” that seems to be all over TikTok (we recommend you stay away from that rabbit hole).
Peptides are short chains of amino acids that do a lot of things, including acting as signalling molecules. They are very popular in skin care. These are pieces of proteins that can tell the skin to make more collagen and elastin. People are especially excited about how they can help firm and plump up fine lines. But it’s important to remember that the body makes thousands of different types of these substances, each with its own health and healing role.
Researchers Exploring Peptides for Hair Growth
Researchers are also looking into some peptides to see if they can help hair grow, make strands stronger, and make hair denser overall. Dr. Munir Somji says, “Hair-growth peptides are short chains of amino acids that help hair follicles grow and send signals to them.” “In hair restoration, some peptides help follicles work better, make the scalp healthier, and support hair growth that is thicker and healthier.” Peptides that help hair grow work by targeting the hair follicle and the tissues around it to make them healthier and work better. Think of them as signalling molecules for the hair and scalp’s current structures. They don’t make new follicles, but they can help the ones that are already there work better.

The Best Peptides for Hair Growth
The Ordinary Multi-Peptide Serum for Hair Density costs £20.70 at Sephora. £13.50 lookfantastic £22 on Amazon. Why it’s Vogue-approved: Peptides are often used in skin care to boost the production of collagen and elastin. When applied to your scalp, they can also help your hair stay healthy and make it look thicker and fuller. This formula uses a mix of its own peptides and caffeine to do just that. Caffeine also increases blood flow to the scalp, which sends more nutrients to the roots.
