Because they're built to work in sequence, not in isolation. The shampoo preps your scalp - clearing DHT with Saw Palmetto and Red Clover, and delivering Copper Tripeptide-1 and amino acids to strengthen strands with every wash. That primes your scalp for the serum, which goes deeper with a concentrated multi-peptide + growth factor complex (Biotinoyl Tripeptide-1, Acetyl Tetrapeptide-2/3, PDRN, NMN) to target thinning follicles at the cellular level.

Used together. Cleanse, then treat - you get better absorption of the serum's actives than using either product alone, plus one consistent routine instead of guessing what to pair. And bundling the two together is more cost-effective than buying them separately.
  • Peptide Serum (45ml) — Targeted follicle treatment included 3 peptides known to help signal cells for growth cycling.
  • Peptide Shampoo (8oz) — Copper peptide cleanse + DHT supportive botanicals to support healthier scalp environment.
  • Free dermaroller with 3-6 month bundles + plus free shipping.

I'll be honest, I dont usually buy a lot of expensive products, even more serums but my hair was bothering me, and my wife actually showed me RGA. I've been using the peptide serum for about 10 weeks and my hair is thicker. Not a miracle but a real difference!
