Your Ponytail Used to Take Two Wraps. After 40, It's Thinning From Two Sides.

Kleos Collagen works on the side you can do something about: the hair you still have. Stronger strands and less snapping* in one full hair cycle, or your money back.

Less snapping by week 12: fewer broken pieces on your brush and in the sink*

Stronger strands: hair that holds together when you brush it, tie it and style it*

More than biotin: collagen and keratin, what hair is built from, plus biotin and zinc

Risk-free for one hair cycle: 90 days, full refund, no subscription

Three Wraps. Then Four. Then It Slips Right Out?

  • You pull your hair back to do the dishes. One wrap. Two. Three. Four, and it still slides down.
  • At home you know which light to stand under. Then a hotel mirror, or a restroom light straight overhead, and your part looks twice as wide.
  • The side part. The powder before you leave the house. The fibers that smudge on your forehead. The biotin bottle in the cabinet, half gone.
  • And the elastic still goes around four times.

Which of these sound like your hair?

Tap the ones that fit.

You didn't do anything wrong.

This happens to a lot of women after 40. And it isn't just one problem.

So what's really going on?

Your Part Is Thinning From Two Sides. Most Products Only Show Up for One.

1. The root side OVER TIME Some roots grow a thinner hair each time. A job for your doctor 2. The strand side snap The hair you still have gets weak and snaps. What Kleos works on

Some roots start growing a smaller hair each cycle. That side runs on hormones. If your part is widening, it's worth a visit to a dermatologist.

The other side is the hair you still have. It's made mostly of keratin, a protein your body builds every day.¹

Think of your hair like a curtain. Thinner threads let more light through, even when none are missing. That's why the hallway mirror is kind and the hotel bathroom isn't.

Ceiling light Thick hair Light stops here Thin hair Light hits your scalp

Same number of hairs. Thinner hairs let more light through.

And weak strands snap. A hair that breaks halfway down is still growing from your scalp. It just never reaches your elastic.

Until the hair you still have gets what it's built from, the strand side keeps working against you.

Why nothing seemed to change

Hair doesn't change on the timeline of a bottle. A strand grows for years, stops, rests for about three months, then falls.²

So the hair in your drain today was decided months ago. And anything you start today won't show until well into the next cycle.

Most of us judge a hair product at week four. That's before hair can show you anything.

One hair cycle

Day 1 You start Week 4 Where mostwomen quit Week 12 The first fair look

Illustration of typical hair-cycle timing.² Not a Kleos result.

That's why everything you've tried let you down

Biotin: one helper. Hair is built from protein, not biotin.
Thickening shampoo: it coats hair that's already grown. It can't change what the next inch is made of.
Fibers and powders: they hide your scalp until the next downlight, or the next smudge.
The side part: it changes the angle, not the hair.
Pricey hair supplements: judged at week four, against your part filling in. That's a root result.

None of it was your fault.Most of it never fed the strand, and little of it got a full hair cycle.

So what does?

The Strand Refill Feeds the Hair You Still Have.

Shampoo works from the outside, on hair that's already grown.

Kleos Collagen works from the inside, through the blood supply that feeds every root, while the next inch of each strand is being built. It's the one route a bottle on your bathroom shelf can never take.

Think of biotin like a needle:

Biotin alone EMPTY Biotin is the needle. But there's no thread. Nothing to sew with Kleos Collagen Same needle. Collagen + keratin are the thread. Needle + thread

Same needle. Only one comes with thread.

1

Collagen Peptides + Keratin

So the next inch has something to be built from

Five types of collagen (1,000 mg) bring the amino acids hair is made from. Keratin is the protein your strands actually are, and it brings the ones collagen runs short on.

2

Biotin + Zinc

So the building actually gets done

These are the helpers your body uses to turn protein into hair. Biotin was never the whole job. Here it finally works alongside the materials it needs.

One Full Hair Cycle

So you see the result, not just the wait

Hair rests about three months before it falls and gets replaced. Three capsules a day for 90 days means the hair that grows in has been fed the whole way.

What Kleos Collagen customers mention first:

  • Less hair in the shower and on the brush
  • Strands that feel stronger, with less breakage
  • Hair that looks fuller and healthier
  • Stronger nails, too
  • Softer skin as a bonus

Shampoo and fibers work on the hair you can see, for a day. The Strand Refill works on the next inch, every morning, so the change can build instead of washing down the drain.

Three Capsules. The Rest Happens While You Get On With Your Day.

Not a powder you shake on your part. A daily habit that feeds the hair that's coming in.

Each Morning

3 capsules with breakfast.

No powder to mix, no taste, no smell. That's the whole routine.

The route shampoo can't take.

Yes, your stomach breaks collagen peptides down. That's how they're meant to work. Researchers have found small collagen pieces in the blood after people take them.³

Where Your Hair Is Made

Building blocks, then the build.

The building blocks and the helpers arrive where each new inch is built. Collagen and keratin to build from. Biotin and zinc to get it done.

Over the Weeks

Less on your brush.

Fewer broken pieces on your brush first. Then strands that feel stronger as the fed hair grows in. One night you pull your hair back for the dishes and don't think about it.

The Strand Refill, every day

Keep your shampoo and your hairdresser. Kleos Collagen does the job they can't: what your hair is built from.

Shampoo Coats It. Biotin Helps. Neither Builds It.

Shampoo and fibers stop at the surface. Biotin is one helper. Here's how the options you've already tried stack up.

Already taking biotin?

Then you've already tried one helper. If your hair was short on biotin, you'd likely have seen a change by now. Kleos Collagen adds what biotin alone can't: collagen and keratin, the building blocks, plus zinc. It already has 10,000 mcg of biotin, so you won't need a separate bottle. Finish yours, then switch.

Your First 90 Days

One full hair cycle. Here's what customers tell us to expect.†

Tap each stage to open it.

Three capsules with breakfast. Before the first dose, count your elastic wraps and take one photo of your part under your harshest light. You'll want both at day 90.

Some women see less in the drain early. Many see nothing yet. This is the stretch where most women quit. Keep going.

Strands that feel a little stronger when you tie them up.

“…it doesn't happen over night I think it was maybe two months when I started to see the difference”Julie T., Verified Buyer

The hair coming in has been fed the whole way. You pull your hair back for the dishes and don't check the hallway mirror on the way past.

Give it the full 90 days. If your hair doesn't feel stronger, you get every penny back.

This is a one-time purchase. 

No subscription or recurring charges.

Hair that feels stronger in 90 days, or you pay nothing.

You've paid for gummies you judged at week four. Shampoos that washed out. Fibers that smudged.

 

So here's the deal.

 

Take Kleos Collagen every day for 90 days. That's one full hair cycle, the time hair actually needs, not a 30-day window that ends before your hair can show you anything.

 

If your hair doesn't feel stronger, email us and we'll refund every penny.

 

No hoops. No questions about whether you took it every single day.

 

You only keep it if it works.

How soon will I notice a difference?

Hair runs on a roughly three-month cycle, so give it time. Some women see less in the drain within a few weeks. Stronger-feeling strands usually show as the fed hair grows in, around 8–12 weeks. That's why the guarantee runs the full 90 days.

 

"it doesn't happen over night I think it was maybe two months when I started to see the difference" (Julie, Verified Buyer)

Will this fill in my part?

Not on its own, and we won't pretend it will. If some roots are growing smaller hairs, that's the root side. It runs on hormones, and a dermatologist is the right person for it.

 

Kleos Collagen works on the strand side: the hair you still have, so it's built from better materials and snaps less. Most women are dealing with both. Count your wraps today and again at day 90. If your hair doesn't feel stronger, you get every penny back.

Collagen doesn't block DHT. So why would it help?

You're right, it doesn't, and we don't claim it does. DHT works on the root. Kleos Collagen works on what the strand is built from.

 

That's a separate job, so it sits alongside whatever your doctor recommends, minoxidil included.

Doesn't stomach acid destroy collagen?

It breaks it down, and that's how collagen peptides are meant to work. They're already cut into small pieces before you take them, and researchers have found small collagen pieces in the blood afterward.³

I already take biotin. Isn't that the hair vitamin?

Biotin is one helper. It makes the biggest difference when you're short on it, and most women aren't.

 

Hair is built from protein, which is why Kleos Collagen pairs 10,000 mcg of biotin with collagen, keratin and zinc. You won't need a separate biotin bottle, so finish yours and switch.

Why didn't the hair products I already tried work?

Usually one of three reasons:

 

1. They worked on the surface. Shampoo coats hair that's already grown. Fibers hide the scalp until they wash out.

2. They gave your hair one helper, not the building blocks.

3. Some of them you judged at week four against your part filling in, before hair could show you anything.

 

None of that is on you.

Is 1,000 mg of collagen enough?

Some powders have more collagen per scoop. Kleos isn't built to win on grams. It's built to bring collagen, keratin, biotin and zinc together, in capsules you'll actually keep taking for a full hair cycle.

 

And if you eat less protein than you used to, your hair is often one of the first places it shows.

I'm in my fifties. Is it too late?

Your body builds new hair every day, at any age, from whatever it's given. The hair growing in this month can be fed better than the hair that grew in last year.

 

If it doesn't feel stronger after 90 days, it's free.

I'm on HRT or minoxidil. Can I take this too?

Yes. Kleos Collagen has no hormones and no drugs, so it works with or without them.

 

It doesn't treat menopause symptoms or replace your treatment. Show the bottle to your doctor if you'd like a second look.

How do I take it? Is 3 capsules a lot?

Three capsules once a day with breakfast, or spread them across the day. They're about the size of a fish oil capsule.

 

If pills are hard for you, start with 2 for the first few days, then build to the full 3.

I take a multivitamin and get blood work. Anything I should know?

Check the overlap. Kleos Collagen includes 10,000 mcg biotin, 50 mg zinc and vitamin A, so compare the full label with your multivitamin and ask your doctor if you're unsure.

 

High-dose biotin can interfere with some lab tests, including thyroid and heart tests. Tell your provider you take biotin before any blood work.

Are there allergens or animal ingredients?

Yes. The collagen comes from hydrolyzed bovine collagen peptides, chicken broth protein and hydrolyzed egg membrane, so the formula isn't vegan or vegetarian. The capsule shell is vegetarian.

What if it doesn't work for me?

Then it's free. If your hair doesn't feel stronger within 90 days, email us and we'll refund every penny. No hoops, no interrogation.

How fast will my order arrive?

Orders ship within 48 hours and typically arrive in 5–10 business days. We'll send you a tracking number the second it ships.

Feed the Hair You Still Have. Start the Clock Today.

Hair needs about 12 weeks to show a change, so every week you wait is a week later you'll know.
