The Gray XI LE SOURCIL Eyebrow Pencil would suit someone whose eyebrow is gray. If your hair is white, gray, or ashy with no golden highlights, then this crayon gray shade is definitely a must-try. 
 
The very high precision LA SOURCIL by Angelik Infenneker, a well-known French makeup artist, is available in eleven shades that naturally adjust to your colors (those of your eyebrow, your hair, your complexion) and your character to magnify them. The crayon's dry texture allows for flawless hold, which requires no retouching during the day. Thin, long-lasting, not requiring a sharpener, water-resistant, it reproduces the line of the hair and provides a nuanced effect without effort. The look takes shape.
 
HIGHLY RECOMMEND USING THE LA SOURCIL BRUSH AND THE GEL FOR THE BEST RESULT.
