Eternal Blue is a haircare brand, bridging time-tested Mongolian knowledge into new contexts. We believe in working with what is near: the materials, traditions, and relationships that form our environment. In Mongolia, the use of foraged botanicals for hair was both practical and symbolic, an act of connection to the land and its cycles. Our direct and meaningful connection to this lifeworld continues to inform how we create and think about hair care.

Targeted support for scalp health and follicular longevity.
Independent Clinical Results
Eternal Blue was developed around the understanding that hair health is not determined by a single process. The scalp environment, follicle activity, hair fibre integrity and the natural cycle of growth and shedding influence one another. This is why the Restoring System is designed to support hair comprehensively, with attention to the conditions and natural processes involved in healthy hair growth.
Traditional knowledge informs where we look; careful formulation determines how we apply it. Each formula is thoughtfully developed with close consideration given to ingredient compatibility, balance, stability and performance, and is made with over 95% naturally derived ingredients.
The complete Eternal Blue Restoring System was independently evaluated in a 150-day in-vivo clinical study under normal-use conditions. 40 participants with dermatologist-confirmed telogen effluvium completed the study, with changes assessed through phototrichogram imaging, instrumental measurements of hair fibre diameter and tensile strength, standardised shedding assessment and participant self-assessment. The study was conducted by ALS Beauty & Personal Care in accordance with Good Clinical Practice guidelines.
Hair fibre diameter was measured at the base using precision micrometry, while tensile strength was assessed under controlled traction. After 150 days of use, average hair fibre diameter increased by 11.3% and average tensile strength increased by 11.7% — both statistically significant results.
In self-assessment, 92.5% of participants rated the products effective for hair thickness, while 82.5% reported that their hair felt stronger and less brittle. A further 87.5% reported improved elasticity, with hair feeling more resilient and less prone to breakage.
Phototrichogram analysis measured changes in the number and density of mature terminal hairs.
After 150 days, average terminal hair count increased by 6.8%, while average terminal hair density increased by 6.9%, with over half of participants showing improvement across both measures — supporting a positive increase in mature terminal hair and the broader improvements seen in hair growth quality.
In self-assessment, 92.5% of participants rated the system effective for hair thickness, while 75% reported that their hair appeared thicker or denser at the roots.
Terminal hair count and density showed positive average increases, with variation in the magnitude of individual responses affecting statistical significance.
Phototrichogram analysis measured changes in the proportion of fine vellus hairs and mature terminal hairs. Vellus hairs are finer hairs, while terminal hairs are the mature hairs that contribute more to visible hair density and fullness.
After 150 days, the average vellus hair rate decreased by 9.4%, while the average terminal hair rate increased by 2.1% — both statistically significant changes, indicating a shift towards more mature terminal hair growth.
In self-assessment, 90% of participants noticed an improvement in their hair growth, while 85% rated the products effective for hair growth rate.
Hair shedding was assessed through standardised combing and washing tests, counting hairs shed from the root during dry combing. After using the full Eternal Blue set for 150 days, root-shedding decreased by 31.7% on average — a statistically significant result.
In self-assessment, 87.5% of participants rated the products effective at reducing shedding.
The findings above show improvement across multiple dimensions of hair health — from terminal hair growth and density to fibre thickness, strength and root shedding — supporting the comprehensive approach behind the Restoring System.
We believe meaningful efficacy comes from working with the natural processes that support healthier hair.
