HAIRBEAURON 4D PLUS [CURL]

The HAIRBEAURON 4D Plus [CURL], equipped with the “Bioprogramming” proprietary technology, beautifully adds shine and moisture to hair, even by clamping for 30 seconds at 360°F. You will be able to notice a visible change in your hair from root to tip, just by clamping a section of hair for an extended period of time.

※ If you apply the high-temperature device to hair treated with coating agents or oils, their components may cause chemical changes due to the heat and damage hair. Please do not use in this way.

The Equation for Beauty
P = λ(nD)t — Lumielina's Equation for Beauty

The power to become beautiful is a function of the density of the Bioprogramming field (D) and the time spent within it (t). Choosing a higher density is choosing a higher ceiling.

§ Why this D

Where 4D
sits.

Every Lumielina device is rated by the density of its ionic field. Higher D compresses more work into the same time — less heat exposure, more durable result. Pairs of equivalent D (Repronizer + HairBeauron) form the discipline of Mitsudonose.
