THERMAL PROTECTION & HAIR FIBRE STRENGTHENING

Visualise and quantify keratin degradation down to the cortex through XPolar® technology

XPolar® technology enables :

• the demonstration of the thermoprotective, repairing, and strengthening efficacy of hair care products,
• the comparison of the impact of various styling devices (straighteners, curling irons, hair dryers),
• the assessment of improvements in the structural integrity of keratin within the hair fibre,
• the analysis of the effects of complete hair care routines, targeted treatments, or dietary supplements, including in & out strategies.

FILM-FORMING EFFECT, FIBRE COATING, PROTECTION & RESTORATION

Hair, eyelashes, and beard hair

Visualise and measure surface effects on keratin fibres through XFluo® 3D technology

The protocol is based on :

• 3D and 4K imaging of the fibre surface,
• the calculation of roughness parameters, before and after application.

This approach enables a comparative and objective assessment of coating, smoothing, protective, and restorative effects, particularly on short and exposed fibres such as eyelashes and beard hair, which are highly sensitive to mechanical and environmental stressors.

THICKENIING EFFECT

Caucasian and Asian hair

Precisely measure hair fibre diameter through XLED technology

This measurement can be performed on all hair types, including Asian hair, characterised by a larger diameter and a more cylindrical shape. It serves as a reference method to :

• verify thickening, volumising, or densifying effects,
• conduct research studies to better characterise hair fibres,
• integrate this measurement into preventive or corrective protocols, on tresses or panels.

NAIL INTEGRITY, PROTECTION & RESTORATION

Analyse keratin structure at the core of the nail through XPolar® technology

We measure :

• the efficacy of protective, restorative, and strengthening products,
• the impact of chemical (detergents, solvents), oxidative (UV), and mechanical (polish, removal) stressors,
• the performance of active ingredients or formulations in the R&D phase through rapid and precise screening.

Understanding what occurs at the core of the nail provides objective and tangible evidence of product efficacy.
