Calecim Professional

Summer may be over, but the stress it leaves on your hair can linger.

“UV rays from the sun degrade keratin, the main structural protein in hair,” explains consultant dermatologist and hair expert Dr Aamna Adel in The Times—leaving hair drier, rougher and more vulnerable to breakage.

But post-summer recovery shouldn’t focus on the hair fibre alone. Heat, sweat, frequent washing and product build-up can also disturb the scalp environment. That’s why a thoughtful hair-health plan begins at the root: restoring scalp comfort, supporting its protective barrier and encouraging a balanced microbiome.

Once that foundation is in place, PTT-6®️ can help support the scalp and hair-follicle environment. Its proprietary blend of growth factors, cytokines and exosomal proteins supports cellular communication and helps create the conditions necessary for strong, healthy growth.

Truly healthy hair doesn’t begin at the ends. It begins with a well-cared-for scalp. Support your follicles. And ensure a healthy growth cycle throughout the year.

WE WON!

We’re thrilled to announce that the CALECIM®️ Hair Serum has been named ELLE UK’s No. 1 pick for hair in the 2026 Tweakment Awards.

Powered by our proprietary PTT-6®️ technology, the six-week system combines targeted scalp application with precision microneedling. Its complex of more than 3,000 proteins—including growth factors and exosomal proteins—is designed to support the scalp and follicle environment, helping address shedding and encourage fuller, healthier-looking hair.

This recognition celebrates the science behind CALECIM®️ and our belief that better hair health begins at the scalp.

Thank you to ELLE UK, our professional partners and everyone who has made CALECIM®️ part of their hair journey.

Award-winning science. And results that are recognized: The winning combination of technology and real life evidence.

One active. Two distinct applications. Many ways to see the difference.

What makes PTT-6®️ so distinctive is its ability to bridge advanced skin and hair science—bringing the same proprietary regenerative technology to two very different beauty concerns.

Containing more than 3,000 proteins, including growth factors, cytokines and exosomal proteins, PTT-6®️ supports the cellular communication involved in renewal.

For skin, it helps support a firmer, more supple and healthier skin.

For the scalp and hair, it helps create a healthier follicular environment—supporting reduced shedding and thicker regrowth.

Few beauty technologies are recognized for their potential across both skin and hair. That versatility is the uniqueness—and the power—of PTT-6®️.

One intelligent active. Targeted formulations. Visible benefits.

It’s no miracle. It’s Science.®️

CALECIM®️ Hair Serum is featured in The Sunday Times Style’s guide to hormonal hair changes, with trichologist Hannah Gaboardi Hannah Gaboardi recommending it for at-home care in the article’s discussion of postpartum hair loss.

Your hair changes with your life. Understanding why makes a difference.

In “Thick and Thin”, writer Hannah Coates explores how puberty, pregnancy and menopause can affect our hair—and why care should respond to each stage.

After pregnancy, falling oestrogen levels can cause more hairs to enter the shedding phase together. The change can feel dramatic, making expert guidance and an understanding of the underlying cause especially valuable.

The feature highlights our PTT-6®️ powered treatment as “designed to support follicle renewal”, alongside the microneedling Activator to help improve absorption.

We’re delighted to be included in a conversation that puts understanding your hair—and the science behind its care—first.

CALECIM®️’s PTT-6®️ technology takes the spotlight in an article featured in The New York Times exploring regenerative skincare, hair thinning and the science of aging. Can cell-signaling technology really improve how our skin and hair behave?

The article raises an essential point:

“Not every ‘regenerative’ claim has the same evidence behind it.”

Here’s what matters.

1. Is the science plausible?
Yes. Growth factors and other signaling proteins can influence processes involved in skin repair and the environment around hair follicles.

As Dr. Phoebe Jones explains in the article, “we’re trying to improve the biology of the skin itself.”

But a plausible mechanism is only the beginning. Each technology needs evidence of its own.

2. How powerful is the active ingredient?
Its source, concentration and biological activity matter. Simply including exosomes or growth factors does not establish effectiveness.

CALECIM’s PTT-6®️ combines naturally produced growth factors, cytokines, proteins and exosomes derived from proprietary umbilical cord lining stem-cell technology. This complex mixture delivers multiple biological signals, with its activity investigated in laboratory and human studies.

3. What should you look for?
Research showing both how the technology works and what improvements occur in people. Check the formulation tested, study size, results and safety reporting.

Expect gradual improvements in skin quality and healthier hair with decreased shedding.

The promise is compelling. The evidence behind the active ingredient is what gives it credibility.

More than ingredients. PTT-6®️ influences behavior.

Through cell signalling, PTT-6®️ goes beyond what you apply to your skin and scalp. It helps influence how your own cells respond and function.

Cell messaging is already part of the conversation around exosome skincare and haircare.

Here’s how PTT-6®️ is different:

1. A distinctive stem cell source

PTT-6®️ is derived from ethically sourced stem cells, using patented technology. It contains the biological substances these cells release.

1. More than exosomes

Exosomes are only part of the picture. PTT-6®️ also contains growth factors, cytokines and other stem-cell-derived proteins involved in cellular communication.

This naturally produced complex brings a broad combination of biological messengers together. That complexity is central to the PTT-6®️ approach to skin and scalp health.

1. Studied in the laboratory—and in people

Our research investigates what this complex actually does. And includes both in vitro research—showing how cells respond in the laboratory—and in vivo research—assessing results in people. Together, they help connect how PTT-6®️ works with its visible effects.

PTT-6®️is a biological complex produced by nature. It is not a single exosome, lab-grown ingredient. This is why PTT-6®️ can do what other exosome technology can’t.

It’s no miracle. It’s Science®️.

Some results are especially personal.

“I don’t just talk about CALECIM®️—I’ve seen the journey unfold in my own home.

This is my husband, photographed 24 months apart. No stock imagery and no borrowed transformation. I took these photos, followed his progress and watched the changes happen over time.

CALECIM®️ Hair Serum is powered by PTT-6®️, a cell-signalling complex designed to support the scalp and follicle environment and improve the appearance of thinning hair.

As a hairdresser and CALECIM educator, I can explain the science—but sometimes, the pictures tell the story best.” —

This is what two years of consistent, ongoing use looked like for this user. The progress accumulated day by day, as empty-looking areas filled in gradually and each strand of hair gained its strength and resilience.

PTT-6®️ re-invigorates the growth cycle and activates dormant follicles. Sometimes even we are astounded by the results of our users.

The best thing is …the reward isn’t confined to a 12-week milestone. It’s every day afterwards, when the mirror begins to reflect the hair that you feared you had lost forever.

Individual results and timelines may vary.

One of the most interesting things about PTT-6®️ technology is that the benefit rarely appears in just one place.

You may first notice that your skin looks brighter. Then more even. The contours look a little more lifted. Skin feels denser and looks smoother, clearer and more luminous. Even the eye area can begin to look different.

That is because PTT-6®️ is not designed around one isolated cosmetic concern. Its complex of cell-signalling proteins, growth factors and other bioactive factors supports the skin’s own renewal and repair processes — helping skin function more effectively as a whole.

And when skin is functioning better, the changes tend to appear together:

More density. More resilience.
A more even-looking tone.
Greater luminosity.
Smoother texture.
A visibly firmer, more lifted appearance.

It is why sometimes you can see that something has changed without immediately being able to pinpoint what it is.

Your skin simply looks healthier.

And healthy skin tends to look naturally more youthful, rested and beautiful.

Less said. More seen.
We prefer results to promises.

Growth factor skincare deserves more than marketing claims. PTT‑6®️, the proprietary ingredient behind CALECIM®️, has been investigated through both in‑vitro and in‑vivo research published in peer‑reviewed medical journals.

In‑vitro research allows scientists to examine biological activity under controlled conditions. In‑vivo research assesses what happens in living skin. Peer review adds another level of scrutiny, with the research evaluated by experts in the field before publication.

Together, these studies help us understand how PTT‑6®️ supports our body’s natural renewal and repair processes—and why meaningful skin and hair improvement develop progressively over time.

Why this is important? Because you should be confident of your choices and you deserve more than a promise. We believe our trustworthiness as a technology should come from science that can be examined.

“This client came to us concerned about the visible thinning through the top of his hair and wanted to see if we could improve the overall appearance of density and fullness.

We started him on our CALECIM®️ 6-Week Hair Program… and these are his results after just 6 weeks🤍

The difference in the appearance of his hair through that top area has been incredible — it looks fuller, healthier and so much less visibly sparse.” Jacobs Well Hair & Beauty
