How does gray eyelash tint work?

Answer 1

You should not use these dyes and tints

Why Eyelash Dyes Are a "Don't"!

Here's why you should avoid eyelash dyes, even those advertised at upscale salons or spas, or for at-home use:

• The biggest concern about using eyelash dyes is that they can cause blindness! Yes, blindness! Now that's suffering for beauty! It won't matter how dark or noticeable your lashes are if you're not able to see them!
• Along with the possibility of blindness, eyelash dyes can cause swelling, inflammation of the eye itself, and eye infections that may land you in the hospital.
• The U.S. Food and Drug Administration (FDA) absolutely prohibits the use of hair dyes for eyelash (and eyebrow) tinting or dyeing, even in beauty salons and other establishments.
• Despite what you may have heard at your salon, there are no color additives or coloring agents, synthetic or natural, approved by the FDA for dyeing or tinting eyelashes-either by professionals or by consumers at home.
• There are no "natural" or "organic" eyelash dyes. If it changes the color of your lashes, then it means the exact same dyes that you find in permanent hair dyes (for the hair on your head) are being used. And only synthetic dyes (which are not approved either) can change blond or red hair to dark brown or black.
• United States law requires all hair-dye products (1) to include instructions telling users to perform patch tests before they use them so they can determine if they may have an allergic reaction, and (2) to carry warnings about the dangers of applying these products to eyebrows and eyelashes. We know, we know…who takes the time to do those tests before covering their gray roots, right? But, the warning about dyeing your eyebrows and eyelashes is there because it is so dangerous!
