NO initial shedding phase

Unlike Minoxidil (Rogaine), our serum doesn't trigger a shedding phase. Most men report LESS shedding within 2-3 weeks, not more.

The 4 clinical actives work to strengthen existing hair while stimulating new growth—without the "worse before better" period.

Our serum combines four clinically-backed actives shown to support visible regrowth and reduce shedding — without prescriptions or harsh chemicals.

  • 3% Rosemary: Blocks DHT & stimulates blood circulation to the scalp, promoting stronger, healthier hair growth.
  • 3% Redensyl: Reactivates hair follicles at the root level to boost new hair growth and reduce hair fall.
  • 2% Aminexil: Prevents collagen buildup around hair roots, helping to reduce hair thinning and loss.
  • 2% Anagain: Prolongs the hair growth phase and reactivates dormant hair follicles.

    Each ingredient is dermatologist-tested and backed by independent studies — giving you science-level results in a simple, daily roll-on.

Most users begin noticing less shedding within the first 3–4 weeks of consistent use.

By weeks 6–8, many report seeing new baby hairs and thicker coverage around thinning areas.

For best results, use it daily for at least 60 days — consistency is key.

Our formula works by reactivating dormant follicles and strengthening existing strands, so results compound over time.

And if you don’t see a visible difference in 60 days, you’re covered by our money-back guarantee — no questions asked.

1. Use it for 90 days

2. If you don't see results, contact us

No questions. No hassle. No risk.

Why? Because we know it works. And we know you've been burned by products that didn't.

Results That Speak for Themselves

If this worked for me it'll work for anyone
"Bro my crown was THIN. Like you could see my scalp in normal lighting. I was thisclose to just shaving it all off.Tried this as a last ditch effort. Took longer for me (probably cause I waited too long to do something) but after 10 weeks I started seeing baby hairs. After 4 months theres definately more coverage.Its not perfect but I went from "gonna have to shave it" to "ok I can work with this." If your thinking about it just try it, the guarentee is real."
Derry (Verified Buyer)
A must have!
“A year on minoxidil = itch, pillow stains, constant worry and crazy shedding once you stop using it. The roll-on is clean and takes 30 seconds. By month three my barber noticed a thicker crown, and I stopped hiding under hoodies. Real results, zero paranoia.”Dean D. (Verified Buyer)
Dean D. (Verified Buyer)
Very Satisfied!
“I’ve tried everything — oils, shampoos, gummies. Nothing ever made a real difference. This hair serum is the first thing that gave me results I could actually see. I made it a part of my routine now, like brushing my teeth.”
James R. (Verified Buyer)
Was ready to call BS
not gonna lie I thought this was another scam product. I've wasted so much money on amazon serums and that mielle oil everyone was hyping (made me shed MORE btw).Only tried this cause of the money back guarentee. Week 4 I'm like "ok maybe less shedding?" Week 7 my gf pointed out new hair growing and I was like holy sh*t its actually working.Still using it 3 months later. My hairline isn't perfect but its WAY better than it was.
Andy (Verified Buyer)
Finally, Results Without The Side Effects
Used Rogaine for 2 years and dealt with constant scalp irritation and that awful initial shedding phase. Switched to the 4 in 1 hair serum 3 months ago and got the same results WITHOUT the side effects. My scalp feels normal again, no irritation, and I'm seeing new growth at my temples. Week 3 the shedding stopped, Week 6 baby hairs started appearing. Worth every penny.

Frequently Asked Questions

If you're noticing early thinning especially around your hairline or temples Cotevich is built for you. Thousands of men have used this precision delivery system to bypass The Follicle Block. It’s not magic, it’s targeted consistency.

Most guys start seeing baby hairs in 2–4 weeks. It depends on your follicle health and consistency but daily use gives your scalp the direct ingredient delivery it needs.

Not at all. Our Hair Regrwoth Serum was designed for daily life — clean, fast-absorbing, and non-greasy. Use it before work, the gym, or whenever fits your routine. No mess, no smell, no problem.

No drugs, no gimmicks. Cotevich uses precisely dosed botanicals Redensyl®, Rosemary, Aminexil, and Anagain™ ingredients backed by research, not side effects.

Then it’s on us. You’re covered by our 90-Day Guarantee: use it consistently, and if you don’t see baby hairs growing, we’ll refund every cent. No risk. Just results.

Yes, to sustain results, you’ll want to transition into a maintenance routine once your desired density is achieved. But “maintenance” doesn’t mean full strength forever. You may only need to apply every other day or reduce usage. What matters is consistency rather than daily maximum dosage.

We’ve formulated the hair growth serum to be gentle (no harsh solvents or strong acids). But if you have active scalp issues like psoriasis, eczema, open wounds, or severe dermatitis, patch test before use (apply behind the ear for 48 hours). If irritation, redness, or burning occurs, discontinue use. Always consult a dermatologist if you’re unsure.

Skipping a day or two won’t ruin your progress. Hair growth is gradual, and what matters is consistency over months, not perfection every single day. And since Cotevich comes in a compact roll-on, it’s designed to be travel-friendly — just toss it in your bag or carry-on so you can stay on track wherever you go.
