The 5 signal peptides
Saw Palmetto
A botanical long favored in men's hair care, traditionally used to support a healthy-looking scalp.
Rosemary
Invigorates and refreshes the look and feel of the scalp — a botanical favorite in modern hair care.
Eucalyptus
Clarifies and purifies for a clean, fresh, balanced-feeling scalp environment.
Baikal Skullcap
A root extract rich in plant antioxidants that help defend against everyday environmental stress.
Soybean Germ
A nourishing plant extract that supports a healthy-looking scalp and softer, conditioned strands.
The truth about thinning
Your hair density peaks in your late 20s. By your mid-30s, the strands themselves start shrinking as follicles miniaturize.
By 35, two-thirds of men already have noticeable hair loss. By 50, roughly 85% have significantly thinning hair.
It happens quietly, a little every year — until the barber mirror, a bright bathroom light, wet hair after a shower, or an old photo makes it impossible to ignore.
Waiting isn't neutral. The good news: if you caught it early, this is the easiest stage to take control.
Hair density peaks around age 28, then declines steadily with age — from near its peak in the late 20s down to a fraction of it by the 80s.
5 peptides + 5 botanicals built to defend your density — without prescriptions or greasy oils.
Why it works
Day 1
Peptides absorb and get to work at the follicle.
Day 30
Scalp feels healthier; shedding starts to calm.
Day 60
Strands look fuller and more resilient.
Day 90
Visibly thicker, denser-looking hair.

How Thickr Compares
Our approach
No prescription. A once-daily scalp serum with five signal peptides plus saw palmetto, rosemary, eucalyptus & Baikal skullcap — designed to support the appearance of fuller, denser-looking hair. Fragrance-free, vegan.
No prescription, but applied daily and used indefinitely — gains are typically lost if you stop. Can cause scalp irritation and an initial shedding phase.
Prescription only. Carries possible sexual and mood side effects, and is not recommended for women of childbearing potential.
Thickr is a cosmetic product — not a drug — and isn't intended to diagnose, treat, cure, or prevent any condition. Information on minoxidil and finasteride reflects commonly documented points; read product labeling and consult a healthcare provider about what's right for you.
The 30-Second Routine
Apply a few drops of serum directly to the scalp — focus on the crown, temples, and hairline, where you'd like to support the appearance of fuller-looking hair.
Gently massage the serum into the scalp using your fingertips for 1–2 minutes to ensure even distribution and stimulate circulation.
Do not rinse. Style as usual. Use once daily, consistently, for best results. Morning or evening — whatever fits your routine.
For external use only. Avoid contact with eyes. Keep out of reach of children. Store in a cool, dry place.
