Eyelash tint is a form of hair dye developed for specific use on the eyelashes. Eyelash tinting produces a similar effect to mascara. It visibly lengthens, darkens and thickens the appearance of eyelashes without smudging, clotting or rubbing off.
Although the eyelash tint itself is permanent, the effects will only last as long as the growth cycle of your eyelashes. As each dyed lash reaches the end of its growth cycle it will fall out and cause the darker look of your lashes to gradually fade over time.
Your eyelash tint will last around 4-6 weeks, depending on the growth cycle of your lashes.
