Study Framework

Before. After 6 months.

Standardized TrichoLAB documentation under identical capture conditions. Camera angle, lighting, and crop stayed unchanged throughout the entire study period.

Methodology

The study in detail.

The six-month consumer use study documents how hair density changes under real-world conditions of use. The analysis combines objective hair analyses with standardized photo documentation and structured self-assessment.

Study Design

  • The study group

    23 participants in total. Data was collected across two independent study arms over a period of six months.

  • Objective measurement methods

    Hair density was captured at the start and after six months using TrichoLAB hair analysis and standardized Canfield photo documentation.

  • Structured self-assessment

    Assessment of hair growth, hair density, tolerability, and application via standardized questionnaires.

„Was für mich den Ausschlag gegeben hat, war die einfache Anwendung: zweimal pro Woche, mehr nicht. Genau deshalb bin ich konsequent drangeblieben, und nach ein paar Monaten hatte ich das Gefühl, dass mein Haar insgesamt wieder voller und kräftiger wirkt."

Testimonials

  • “Since adding Mallia 8T3 to my routine, there has been a literal explosion of new hair follicles. After about 4.5 months of use — twice a week — hair density in the mid-scalp area went from 142 to 197 hairs per cm².

    The share of new, fine hairs (<30 µm) climbed from 26% to 61%. That points to strong activation of previously dormant follicles, which have now entered the growth phase as new hairs.

    Even my stubborn right temple, which had visibly lost density at the 6.5-month measurement (down to 66 hairs per cm²), has almost fully recovered since adding Mallia 8T3 and is back to its original level at 118 hairs per cm².”

Mode of Action

The concept behind 8T3.

Rather than copying established paths, 8T3 follows its own research approach. At the center are the natural growth processes of the hair, along with a formula that emerged from decades of immunological research.

The active ingredient

What is sCD83?

sCD83 is the body's own protein and has been studied scientifically for many years. From it, 8T3 developed MAL-838 — a specially formulated variant for cosmetic use. At its center is a new approach focused on the natural regeneration processes of the hair root.

FAQ

Questions — clearly answered.

Here we answer the most common questions about the methodology, scope, and interpretation of the study.

  • How many people took part in the study?

    A total of 23 people aged 26 to 69 took part in the six-month consumer use study. Two established documentation methods were used: quantitative hair analyses with TrichoLAB and Canfield technologies.

  • What does the 87% responder rate mean?

    After 6 months, 87% of participants showed either a measurable improvement or a stabilization of their hair status. Of those, 70% had a documented increase in hair density, while another 17% had their hair loss stopped.

  • When did changes become visible?

    The evaluation was carried out after a period of 6 months. Some participants reported perceivable changes earlier, but the published results refer exclusively to the documented final evaluation.

  • Does “stable” also count as a positive outcome?

    Yes — stable means that hair loss has been stopped. In the study, stabilization was defined as the absence of any further decline in hair density.

  • How was the development of the hair documented?

    The evaluation used quantitative hair analyses with TrichoLAB and Canfield technologies, along with structured self-assessment by the participants. This captures both measurable changes and participants’ personal perception of the application.
