You don’t need a $100 serum—peptide hair growth just got a drugstore price tag from The Inkey List.
The real reason this matters: most hair serums are 90% silicone and fragrance. This one actually lists peptides as the second ingredient—not the last.
It’s $12.99 for 50ml. The claim: stimulate hair follicles with peptides, no prescription needed. I bought it because my part was getting suspiciously wide and I refuse to cry over rosemary oil.
Redensyl Complex
A patented blend that targets the dermal papilla—the root of your hair follicle. Fancy, but it works.

Three heroes here: Copper peptides (repair damaged follicles), Redensyl (wakes up sleeping hair), and caffeine (stimulates blood flow). No filler oils. No alcohol that dries your scalp out.
- Copper Peptides: Repairs follicle damage at the cellular level
- Redensyl: Clinically proven to increase hair density in 30 days
- Caffeine: Increases microcirculation to the scalp
- Glycerin: Keeps scalp hydrated without clogging pores

Water-thin, almost like a toner. Absorbs in 10 seconds flat—no sticky scalp. Smells like nothing, which is honestly a relief after all those “herbal” hair oils that smell like a forest fire.
Week 3 update: less shedding in the shower drain. Not a full mane yet, but my part looks slightly less like a highway. What surprised me: it didn’t irritate my sensitive scalp at all.

After 8 weeks: visible baby hairs around my temples. My ponytail feels slightly thicker. No new bald spots. But if you’re expecting a full mane in 2 weeks, you’ll be disappointed.

For $13, this is the most honest hair serum you’ll find at the drugstore. Peptides, not promises.
