Science of
hair growth.

See visible progress in as little as 6–8 weeks with consistent daily use.*

Start growing

Kickstarts

follicle activation

Peptide growth factors signal dormant follicles to re-enter the anagen (active) phase, extending the window where new hair can form.

Ref: Capixyl, Biopeptide-EL — peer-reviewed efficacy data available on request

Extends

the growth phase

Caffeine and vasodilating actives increase scalp blood flow, delivering nutrients to follicles and extending the duration of the active growth cycle.

Ref: Fischer et al., Int. J. Dermatol. 2007 — topical caffeine penetration within 2 mins

Stimulates

and thickens

Saw palmetto blocks DHT — the hormone that miniaturises follicles — without hormones. Strands grow back stronger, thicker, and anchored more deeply in the scalp.

Ref: J. Altern. Complement. Med. 2002 — DHT Inhibition via 5a-reductase blockade

Clinically Reviewed
Hair Growth Serum*

Vitēra is the first hair serum I've reviewed where the ingredient list actually matches the dose needed to work. I recommend it to patients who want results without a prescription.

Dr. Elena Marsh, M.D.

FAAD Board-Certified Dermatologist

What stood out to me is the honesty around timelines. Most patients give up at week 3 because they were promised 30-day results. Vitēra sets realistic expectations and that builds compliance.

Dr. Amara Osei, M.D.

Board-Certified Trichologist

As a physician I rely on the science before recommending anything. The DHT-blocking mechanism here is well documented and the peptide complex is dosed at therapeutic levels — not just listed for marketing.

APPLY NIGHTLY · 2 MIN MASSAGE
HOW TO USE

Two minutes. Every night. That's the ritual.

01

Part and apply

Use the dropper to apply 8–10 drops directly to your scalp along your natural part. Focus on areas of concern — hairline, crown, temples.

02

Massage for 2 minutes

Using your fingertips, massage in circular motions. This activates the caffeine vasodilation effect and helps the peptides absorb into the follicle layer.

03

Leave in — don't rinse

The formula absorbs clean. No residue, no greasiness. Apply on damp or dry hair. Best used before bed so actives can work overnight.

04

Stay consistent

Your first real checkpoint is Week 6–8. Daily consistency is what activates the peptide cycle — skipping days extends the timeline.
THE REAL PROBLEM

Most serums are underdosed by design.

The ingredients that actually work are documented in peer-reviewed science. The brands that don't work use them — just at 0.1% of effective concentration, hidden inside "proprietary blends" so you can't verify. We show you everything.

01 — PRIMARY GROWTH SIGNAL

Peptide Complex ×5

FOLLICLE ACTIVATOR

Five growth factor peptides — each targeting a different receptor in the follicle lifecycle. Together they signal dormant follicles to re-enter active growth. Most brands use one. We use five.

Capixyl, Biopeptide-EL, AnaGain — peer-reviewed efficacy data available on request
02 — DHT SUPPRESSION

Saw Palmetto

5A-REDUCTASE INHIBITOR

Androgenic hair loss is caused by DHT binding to follicle receptors and miniaturizing them over time. Saw palmetto blocks the enzyme that converts testosterone to DHT — without hormones.

J. Altern. Complement. Med. 2002; Evid. Based Complement. Alternat. Med. 2012
03 — SCALP BLOOD FLOW

Caffeine

VASODILATOR + DHT ANTAGONIST

Topical caffeine penetrates the scalp within 2 minutes, stimulating microvascular blood flow and nutrient delivery. It also counteracts DHT-induced follicle shrinkage independently — a dual mechanism most brands ignore.

Fischer et al., Int. J. Dermatol. 2007; Skin Pharmacol. Physiol. 2014
04 — KERATIN INFRASTRUCTURE

Biotin (B7)

STRUCTURAL STRENGTHENER

Biotin is essential for keratin synthesis — the protein that forms the hair shaft. Topical delivery at therapeutic concentration strengthens existing strands and reduces breakage that mimics hair loss.

Semin. Cutan. Med. Surg. 2015; bioavailability data available on request
05 — SCALP ENVIRONMENT

Niacinamide

BARRIER + ANTI-INFLAMMATORY

Reduces inflammatory cytokines that trigger premature shedding. Strengthens the epidermal barrier and improves absorption of the peptide complex by prepping the follicular microenvironment.

Int. J. Mol. Sci. 2019; Dermatol. Ther. 2020
06 — HYDRATION + SHINE

Panthenol (B5)

DEEP SHAFT MOISTURISER

Penetrates into the hair cortex — not just the surface — where it binds moisture, increases flexibility, and creates optical shine. Immediate visible result while long-cycle actives do their work.

J. Cosmet. Sci. 2011 — included for immediate visible benefit alongside longer-cycle actives
HONEST TIMELINE

What to actually expect.

We won't promise 30 days because hair biology doesn't work that way. Here is exactly what's happening, week by week.
1
DAY 1–14
Foundation
Peptides absorb into follicle receptors. Caffeine begins increasing scalp circulation. DHT suppression starts. Nothing visible yet — this is biological groundwork.
2
WEEK 3–5
Stabilisation
Shed rate starts to slow. Scalp feels healthier. Existing hair feels stronger. The transition from excessive telogen back into anagen begins.
3
WEEK 6–8
Visible Shift
Fuller-feeling roots. Measurably less shedding. For most users, this is when people around them start noticing before they say anything.
4
WEEK 12–16
Your Story
New anagen growth is visible. Density differences are photographable. This is the version of your hair you've been building toward.
* Results vary. Most subscribers see meaningful visible change at or before Week 8 with consistent daily use.
REAL RESULTS

What consistent use looks like.

90 days. Consistent daily application. These are real customers.

FOUNDERS NOTES
OUR STORY

"We built the brand we couldn't find anywhere else."

We had our own hair stories. Stress thinning. Postpartum loss. The quiet anxiety of watching your hairline change and not knowing what was real and what was just good marketing copy.

We spent a year reading the actual science — the studies, not the blog posts — before we made a single bottle. What we found: the ingredients that work are well-documented. The brands that work are honest about timelines. And the markup on clinic-grade serums is indefensible.

Vitēra is what happens when you stop chasing the marketing and start respecting the biology.

1

Use it daily for 90 days

8–10 drops to the scalp, 2-minute massage, leave in. Daily consistency is what activates the peptide cycle.

2

Take a photo on Day 1

We recommend a scalp photo on Day 1 and Day 90. Changes in density are gradual — comparison photos are where it clicks.

3

If you don't see it, we act

No visible improvement by Day 90? Email us, tell us you tried, and we'll ship a second bottle free. That's the whole promise.
