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.
Natural synergy, contemporary efficacy
We believe in adapting the best of what traditional practices have to offer through thoughtfully developed formulas made with over 95% naturally derived ingredients, with close attention to compatibility, balance, stability and performance.
At the heart of the range are five core botanical actives, chosen for their enduring role in supporting scalp and hair health. Each product is refined with complementary ingredients according to its function, creating a cohesive approach across cleansing, conditioning and targeted scalp care.
Healthy hair is shaped by the relationship between the scalp environment, follicle activity, the quality of the hair fibre and the natural cycle of growth and shedding. Rather than viewing these processes in isolation, Eternal Blue approaches them as part of an interconnected system, informing a complete approach designed to support stronger, fuller and healthier hair.
This same level of consideration extended to how the range was evaluated. The complete Eternal Blue system was independently assessed over 150 days using instrumental measurements and participant self-assessments, allowing us to examine meaningful changes across hair strength, density, growth and retention.
Thicker and stronger hair fibres
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.
Visibly denser hair
Hair density was assessed using phototrichogram imaging, measuring the number of terminal hairs per square centimetre.
After 150 days, average terminal hair count increased by 6.8%, while average terminal hair density increased by 6.9%, with more than half of participants showing improvement in both measures.
These instrumental density results showed positive average improvement, although they did not reach statistical significance due to variation in individual responses.
In self-assessment, 75% of participants reported that their hair appeared thicker or denser at the roots, while 90% reported improved hair growth.
Higher quality hair growth
Phototrichogram analysis measured changes in the proportion of fine vellus hairs and mature terminal hairs.
After 150 days, the average proportion of vellus hairs decreased by 9.4%, while the average proportion of terminal hairs increased by 2.1% — both statistically significant changes, indicating a shift towards healthier, more mature 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.
Reduced shedding
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.
Clinical study
The findings presented above are based on an independent, non-comparative 150-day in-vivo clinical study of the complete Eternal Blue haircare system.
40 participants with dermatologist-confirmed telogen effluvium used the products under normal conditions over 150 days.
Changes were evaluated using phototrichogram imaging, instrumental measurements of hair fibre diameter and tensile strength, a standardised dry-combing test to assess shedding, and participant self-assessments.
The study was conducted independently by ALS Beauty & Personal Care in accordance with Good Clinical Practice guidelines.
