Choosing Between Them

My top recommendation is the Lunar Tides 8 oz Smokey Purple because it provides the best overall value for consistent color saturation. If you are a casual user, the L’Oréal Feria is excellent for convenience, while the Splat Midnight Amethyst kit is the best fit for those who demand long-lasting results. For those focusing on professional-level results, I suggest using the Wella COLORCHARM toner to prep your hair, followed by the deep, rich pigment of ARCTIC FOX if you want to customize your own smokey shade.

Please remember that these dyes, regardless of the brand, require pre-lightened hair to achieve the true Smokey Amethyst result. If your hair is too dark, the pigment will not show correctly, leading to frustration. Always check your base color carefully before starting your application to ensure your efforts yield the muted, professional look you want.
