Hair Care · Five-Peptide Scalp Serum
Peptide Hair Growth Serum
For thinning that's past 'just use rosemary oil.' Five hair peptides go to work at the scalp to support the look of fuller, denser hair and stronger-feeling strands — the next level when oils alone aren't cutting it anymore.
- The look of fuller, denser hair and less visible shedding over consistent use
- Five hair peptides target the scalp — the next step up from oils alone
- Stronger-feeling strands at the hairline and temples, where thinning shows first
- A lightweight leave-in serum that won't leave hair greasy or weighed down
Why it works
When oils aren't enough, peptides are the next level.
Shedding at the hairline and temples is the part that shows first and worries you most.
Peaceful Night
Massaged in daily, the serum supports stronger-feeling strands and the look of density right where thinning is most visible.
Hair treatments usually leave your hair greasy or flat.

Good to know
Five hair peptides work at the scalp to support the look of fuller, denser hair and stronger-feeling strands, especially at the part and temples where thinning shows first. It's a cosmetic scalp serum working on appearance — it isn't a drug and doesn't treat any medical cause of hair loss.
Enough to lightly cover your part and thinning zones — usually a small dropper's worth. Once daily is the standard; twice is fine if the label allows, but more won't speed the hair cycle up. Consistency over months is what matters.
Hair works on a slow cycle, so give it a full 90 days of daily use. The look of fullness and reduced shedding builds gradually — consistency is everything.
It goes on the scalp rather than the lengths, so it won't strip or affect colour, and it's fragrance-free for a sensitive scalp. If you're pregnant or nursing, check with your provider before starting anything new.
Around two months with daily use — the multi-bottle bundle covers the full cycle these results need.
Keep it somewhere cool and dark; heat and light are hardest on peptides.
The peptide serum is the targeted, higher-strength step for thinning past the oil stage. The botanical serum is a gentler daily herbal option; the scalp oil is a nourishing weekly massage treat. Many people layer the routine as their thinning warrants.

Questions, answered
How much do I use and how often?
Apply it directly to a dry or towel-dried scalp along your part and thinning areas once a day, then massage in. It's a leave-in — don't rinse it out.
How long until I see a difference?
Hair works on a slow cycle, so give it a full 90 days of daily use before judging. The look of fullness and reduced shedding builds gradually — consistency is everything here.
Will it make my hair greasy?
No — it's a lightweight, water-based leave-in that absorbs into the scalp rather than coating the hair. It won't weigh your style down.
Is this a hair-loss treatment?
It's a cosmetic scalp serum that supports the look of fuller, denser hair and stronger-feeling strands. It isn't a drug and doesn't treat any medical cause of hair loss — for that, see a doctor.
Can I use it with the hair oil or the botanical serum?
Yes — many people use the peptide serum daily and add the nourishing scalp oil as a weekly massage. Apply the lightweight serum first and let it absorb before any oil.
Can I use it on colour-treated hair?
Yes — it goes on the scalp, not the lengths, and won't strip or affect colour.
How should I store it?
Keep the cap on and store it away from heat and direct light so the peptides stay effective.
