PERCEPTION OF HAIR COLOR

The appearance of the hair’s color depends on primary and secondary color reflection. 
The surface texture and the inner structure influence the shine and vibrancy of the hair color.

 

PERFECTLY REFLECTED LIGHT

 

Light is reflected from the cuticle and from inside the hair.
The inside reflection creates color depth.

For hair to have a natural shine, the light needs to be
reflected on an even and thus healthy surface where
the cuticle lays flat.

 

PERFECTLY REFLECTED LIGHT

 

Reflected light at back-surface travels inside
the hair fiber and reflects the color of hair.

LIGHT SCATTERING

 

Light can also interfuse the hair, meaning light rays are 
reflected from inside.

This is known as secondary reflection. If the light rays inside 
the hair are refracted or diffused by an uneven inner structure, 
the hair will be less shiny and the color will be less clear.

 

LIGHT SCATTERING

 

Light scattering inside the hair, reduces contrast, vividness,
depth and transparency.
