Inside Calecim: Understanding PTT-6®, Cytokines and the Proteins That Power Regrowth
Calecim’s patented PTT-6® technology is built on the science of stem cell communication - using powerful proteins, cytokines and growth factors to help your scalp “speak” the language of renewal again. At Hove Hair Clinic, we’re taking the science behind this formula and making it personal, so you can understand exactly how it supports stronger, healthier hair regrowth from the root up.
Key Takeaways
PTT-6® mimics natural regeneration: It’s a nutrient-rich complex derived from umbilical cord lining stem cells, designed to restore healthy cellular communication.
Cytokines and growth factors fuel renewal: These proteins calm inflammation, improve circulation, and trigger follicle activity for stronger, more resilient hair.
Science meets real results: Calecim enhances the impact of treatments like microneedling and laser therapy, helping your scalp regain balance and vitality.
Science doesn’t have to be complicated!
At Hove Hair Clinic, we believe understanding why a treatment works, helps you trust the process.
So, let’s take a closer look at the powerhouse inside Calecim Professional, the patented PTT-6® technology, and break down what it actually means for your hair.
What is PTT-6®?
PTT-6® is Calecim’s exclusive, clinically developed ingredient.
It’s made from a conditioned medium — it’s as a nutrient-rich fluid, collected from ethically sourced umbilical cord lining stem cells (UCLSCs).
These special stem cells are abundant in newborn tissue because they’re designed for repair and renewal. They naturally produce thousands of molecules that help tissue heal, calm inflammation, and encourage new cell growth.
PTT-6® captures that same regenerative “language”, the way healthy cells communicate with each other, and bottles it into a serum that can be applied to your scalp.
Cytokines: The Scalp’s Messengers
Imagine your scalp as a busy city.
Cytokines are the messengers, tiny proteins that carry signals between cells, telling them when to repair, grow, or calm down.
In healthy hair follicles, cytokines help regulate the hair growth cycle, switching follicles from their resting phase (telogen) back into active growth (anagen).
But when inflammation, stress, hormones, or genetics disrupt that balance, the messages get muddled and hair growth can slow or stops altogether.
Calecim’s PTT-6® complex delivers a blend of restorative cytokines to help reset that communication, reducing inflammation and encouraging follicles to behave like they did when they were younger and stronger.
Growth Factors and Proteins: Nourishment at the Root
Alongside cytokines, PTT-6® contains a carefully balanced mix of growth factors and structural proteins, the same kinds your body naturally produces to repair and renew tissue.
These include:
Fibroblast Growth Factors (FGFs) – help rebuild and strengthen the skin around follicles.
Epidermal Growth Factors (EGFs) – support faster cell turnover for a fresher, healthier scalp.
Vascular Endothelial Growth Factors (VEGFs) – improve micro-circulation so follicles get more oxygen and nutrients.
Collagen and Elastin Proteins – support the structure of the scalp and follicle walls, helping hair anchor more firmly.
Together, these molecules form a regenerative “soup” that tells your scalp: “It’s time to grow again.”
Why This Matters for Hair Loss
Most people think hair loss is simply about the follicles, but in truth, it’s about cell behaviour.
If those follicle-supporting cells stop communicating properly, the follicles become sluggish or dormant.
By reintroducing the same growth signals your body naturally produces when it’s healing, Calecim helps restart that conversation, gently, safely, and without the need for blood draws.
This is why Calecim is often combined with treatments like microneedling or low-level laser therapy at Hove Hair Clinic. Microneedling creates tiny micro-channels in the scalp, enhancing absorption of the PTT-6® complex, while low-level laser therapy boosts blood flow and cellular activity, together helping Calecim regrowth serum reach and nourish the areas where it can do the most good.
In short:
Ingredient | Role | Benefit to the Scalp |
|---|---|---|
PTT-6® Complex | Stem cell–derived medium | Restores cellular communication and encourages repair |
Cytokines | Signal-sending proteins | Calm inflammation and trigger new growth |
Growth Factors (FGF, EGF, VEGF) | Regenerative molecules | Improve circulation and cell turnover |
Structural Proteins (Collagen, Elastin) | Strength and support | Help anchor hair and improve resilience |
Calecim Stem Cell Serum - Hove Hair Clinic’s View
We see Calecim as part of a bigger picture: it’s not a quick fix, but a sophisticated tool in long-term hair restoration.
By improving the scalp environment and cellular communication, it enhances every other treatment you pair it with, from microneedling, minoxidil to DNA-guided prescriptions.
Every scalp is different, and that’s why we always start with a detailed consultation and Mediscope analysis to make sure this regenerative technology is right for you.

Q1: What is PTT-6®?
PTT-6® is Calecim’s patented ingredient — a nutrient-rich complex derived from ethically sourced Umbilical Cord Lining Stem Cells.
These stem cells naturally produce thousands of restorative molecules that calm inflammation, repair tissue, and encourage new cell growth.
Think of it as a bottled version of the body’s own healing language, applied directly to your scalp to help restore healthy communication between cells.
Q2: What are cytokines, and why do they matter for hair growth?
Cytokines are small proteins that act as messengers between your cells. They tell follicles when to grow, repair, or rest.
When stress, hormones, or inflammation interrupt those signals, hair growth slows down.
Calecim’s PTT-6® complex helps reset that conversation — encouraging follicles to behave like they did when they were younger and stronger.
Q3: What proteins are found in Calecim, and what do they do?
Calecim contains key growth factors and structural proteins that nourish and strengthen the scalp, including:
FGFs (Fibroblast Growth Factors): rebuild and fortify the skin around follicles.
EGFs (Epidermal Growth Factors): speed up healthy cell renewal.
VEGFs (Vascular Growth Factors): improve blood flow and oxygen delivery.
Collagen and Elastin: support scalp structure and help hair anchor more firmly.
Together, they create a regenerative environment that encourages stronger, healthier hair.
Q4: How is Calecim different from other serums or hair treatments?
Most serums simply nourish the scalp’s surface. Calecim works deeper — at a cellular level — by restoring the communication that drives healthy hair growth.
It helps reduce inflammation, supports follicle longevity, and improves scalp condition over time.
Q5: How long does it take to see results with Calecim?
Everyone is different, but many people notice early improvements — such as reduced shedding or a calmer scalp — within 6–8 weeks.
Thicker, stronger new growth typically appears after several consistent treatments, especially when combined with scalp stimulation therapies and homecare guidance.
Q6: Can Calecim be combined with other treatments?
Yes. At Hove Hair Clinic, we often combine Calecim with microneedling (to open micro-channels for deeper absorption) or low-level laser therapy (to enhance blood flow and cellular energy).
These techniques complement each other beautifully and can help maximise results.
Q7: Is Calecim safe?
Yes — Calecim’s PTT-6® is derived from ethically sourced, medical-grade umbilical cord lining cells and contains no live stem cells.
It’s non-invasive, clinically tested, and suitable for most scalp types.
We always carry out a consultation and Mediscope analysis first to make sure it’s right for you.
