CellResearch presents breakthrough hair data at AMWC Japan

Singapore-based biotechnology pioneer CellResearch Corporation, the discoverers of stem cells within the umbilical cord lining membrane, have unveiled new lab results proving its patented active complex, PTT-6®, improves hair resilience and scalp health. The proprietary technology currently powers CALECIM® Professional, one of the fastest-growing brands in the global medical hair and scalp care sector.

Conducted by an independent testing facility following standardized industry benchmarks, the findings, reported on August 4 and September 8, 2026, provide rare, objective proof for two factors crucial to hair longevity: structural tensile strength and skin tolerance under harsh chemical stress. While many consumer hair brands promise strength and soothing relief, few validate these claims with hard, clinical metrics.

The findings formed the centerpiece of a medical address delivered on September 13, 2026, at the Aesthetic and Anti-Aging Medicine World Congress (AMWC) Japan in Tokyo. Presented jointly by Dr. Ivor Lim, consultant plastic surgeon and Group Chief Medical Officer at CellResearch Corporation, and Dr. Mikiko Hiraoka, board-certified dermatologist and founder of Tokyo's Ginza Richesse Clinic, the presentation highlighted the real-world clinical implications of PTT-6® in advanced scalp restoration.

With these results, CellResearch Corporation is accelerating the international footprint of its professional cosmeceutical brand, CALECIM® Professional. The expansion targets a global hair and scalp care market projected at USD 93.6 billion in 2026, where formulas addressing hair loss, thinning, and scalp health represent the fastest-growing sector.

43% improvement in breakage resistance

In mechanical hair testing, "breaking work" measures the physical energy required to fracture a hair fiber, providing an objective benchmark for how much routine stress a strand can absorb before giving way. Raising this threshold is critical because hair breakage is cumulative rather than immediate: daily brushing, heat styling, and chemical treatments progressively reduce the fiber's structural reserve until the strand fails under tension.

In laboratory testing, bleached human hair treated with PTT-6® demonstrated a 43% improvement in breaking work compared with untreated hair from the same batch.

For salon professionals and colorists, this increase in structural resilience means hair can better withstand intensive chemical services, such as bleaching, perming, and thermal straightening, with significantly reduced risk of post-treatment snapping.

Scalp health: Reducing inflammation to support hair longevity

Scalp sensitivity and irritation frequently disrupt long-term hair care regimens and limit the use of high-performance chemical treatments. By calming micro-inflammation, scalp care formulas can better support the healthy follicular environment required for sustained hair growth and retention.

In a 28-day human study evaluating PTT-6® Scalp Activating Mist, once-daily application yielded a 14% measured reduction in scalp redness (p = 0.016), with 100% of participants confirming that the formula soothed irritation. Longer-term 12-week clinical evaluations demonstrated a 22% decrease in trans-epidermal water loss alongside a 45% increase in scalp moisture, effectively halving trichologist-assessed scalp sensitivity within one month.

At the cellular level, in vitro models showed that PTT-6® suppressed inflammatory signals (the cytokine TNF-alpha) by up to 30-fold, while increasing dermal papilla cell proliferation by 24%. By mitigating inflammatory cascades while simultaneously strengthening hair fiber resilience, PTT-6® offers salons and consumers a double benefit: protecting scalp health during advanced technical treatments while ensuring long-term hair quality and longevity.

Hair growth: Multi-center clinical validation and complete architecture

Beyond strengthening existing fibers and calming the scalp, multi-center international data confirms PTT-6® directly drives visible hair regrowth and density. Across eight independent trials in six countries (including the USA, the UK, Singapore, Australia, Austria, and China), treatment evaluated in 238 patients yielded positive clinical responses in 225 cases: a 94% overall response rate. In a focused 12-week clinical study of 35 patients, quantitative photographic analysis demonstrated a 14% increase in total hair count and a 16% increase in average hair shaft thickness.

While hair care formulations typically target strength, scalp health, or growth in isolation through separate products, PTT-6® provides a unified biotherapeutic platform with clinical validation across all three metrics simultaneously. For professionals and consumers, this comprehensive mechanism provides the foundation for total hair longevity: expanding density and diameter at the root while protecting physical fiber integrity against everyday damage.

Gavin Tan, Chief Executive Officer, CellResearch Corporation says:  "We are thrilled to see that our active ingredient has powerful applications not only in skincare and hair regrowth, but in scalp health and in the strength of the hair strand itself. Each of those is a substantial market in its own right, and each is growing. More than twenty years of research now allows us to address all of them from a single platform."

Dr Mikiko Hiraoka, board-certified dermatologist and founder, Ginza Richesse Clinic, Tokyo, says: "What interests me as a dermatologist is the combination. A calmer scalp, more hair and a stronger strand are usually three separate conversations with a patient, and here they sit together. The scalp findings match what I see in clinic: redness settles first, and the rest follows. I am pleased to be able to offer this to my own patients."

Tom Smith, hairstylist, Aevum Salon, CALECIM® Brand Ambassador, London: "I see the same story in the chair every day: color, heat and time. Hair reaches a certain length and then starts breaking off faster than it grows. Since we brought the CALECIM® haircare range in, the results for hair longevity have been transformative. Clients are keeping length they would have lost, and the hair holds up far better through a color service."

Alfredo Lewis, hairstylist, CALECIM® Brand Ambassador, Los Angeles: "Scalp is where I start with every client now. If the scalp is tight or irritated, nothing you put on the hair afterwards lasts. The CALECIM® haircare range has changed that conversation in my chair. Clients are coming back with calmer, healthier scalps, and the hair growing through looks better for it."

The market: A USD93.6 billion category adding USD 57 billion By 2033

Global hair and scalp care was worth USD 88.2 billion in 2025 and USD 93.6 billion in 2026 and is forecast to reach USD 150.5 billion by 2033 — a 7.0% CAGR, and close to USD 57 billion of new value created within seven years. (Grand View Research)

Hair loss and thinning products are the fastest-growing segment, forecast to compound at 8.6% a year to 2033 — materially ahead of the category as a whole. (Grand View Research)

The dedicated hair loss treatment products market alone is USD 3.14 billion in 2026, rising to USD 4.45 billion by 2031 at a 7.19% CAGR. (Mordor Intelligence)

Asia Pacific is both the largest regional haircare market, at 35.3% of global revenue, and the fastest-growing region for hair loss treatment, at an 8.78% CAGR to 2031. (Grand View Research; Mordor Intelligence)

Asia Pacific professional scalp treatment is a USD 1.17 billion market in its own right, heading to USD 1.61 billion by 2031. Per-capita spending on scalp wellness in Japan and South Korea exceeded USD 50 a year in 2025, among the highest in the world — part of why AMWC Japan was chosen for the presentation.

Shampoo still accounts for 39.8% of category revenue; a mass-market base on which clinically evidenced, higher-value scalp and fiber treatments are the premium growth layer. (Grand View Research)

Most of that market competes on formulation and marketing rather than clinical evidence. CALECIM® Professional sells through clinics and salons; a channel in which a practitioner must be able to defend a recommendation to a paying client, and where data of the kind released today is the product rather than the packaging.

CALECIM® Professional is currently sold in 40 markets through more than 7,000 clinic and salon partners and direct via calecim.com. Over the next year the company plans to expand into North American retail.
