Peptides are everywhere in modern haircare science, yet many stylists and clients still wonder if they truly fix breakage or are just another buzzword. At Rejuvenum – creators of the Amino-15 Hair Straightening System – we rely on verified data, not hype. Below we explain how salon-grade peptides work, why they matter for safe hair smoothing, and how you can add them to your routine for six-plus months of stronger, straighter, frizz-free hair.

What Exactly Are Peptides?

Peptides are short chains of amino acids for hair; think of them as miniature building blocks of keratin. Because they’re smaller than full proteins, peptides can slip past the cuticle, reach the cortex, and start rebuilding weak areas from within. They are the core of many modern keratin alternatives – including our Amino-15 straightening system – that deliver shine without formaldehyde or harsh chemicals.

How Peptides Repair Hair: Four Proven Actions

• Bond Builder: Peptides link neighbouring keratin filaments, reinforcing the fibre without harsh chemicals.
• Cuticle Sealer: By filling microscopic cracks, peptides flatten lifted scales and create mirror-level shine.
• Moisture Magnet: Many peptides are humectants that lock in hydration – crucial for anti-frizz salon treatments.
• Damage Shield: A peptide-reinforced cuticle resists UV, heat, and mechanical stress better than untreated hair.

Independent laboratory tests show that carob-seed peptides inside Amino-15 boost the tensile strength of bleached fibres by 40.9 % [external study placeholder]. That’s real, measurable repair – not marketing fluff.
