Should You Wash Hair Before Coloring


If you’ve decided on a new DIY hair color, you’re probably curious about your dye job prep.  Before you break out the color, it’s always crucial to review all the at-home boxed dye kit steps. While instructions will vary based on the hair dye, there are a few questions that might still need addressing — starting with the most common: Should I wash my hair before dyeing it? 


If you’re unsure whether it's best to forgo shampoo or start the hair dyeing process with squeaky clean hair, we’ve got you covered. Below we break down everything you need to know about washing your hair before dyeing it


Should You Wash Your Hair Before Coloring?

As it turns out, most hair dyes are designed to work better on hair that is not freshly washed. Skipping a wash allows for oils to build up on your scalp, which in return, helps protect against  irritation that can be caused by hair dye. 


Still, though, that doesn’t mean you should skip your cleansing routine altogether in the days leading up to your dye job. Feel free to wash your hair a day or two before your dye session, using the L’Oréal Paris Sulfate-Free Simply Clean Shampoo and the L’Oréal Paris Sulfate-Free Simply Clean Conditioner


If you have curly hair, opt for the L'Oréal Paris Elvive Dream Lengths Curls Moisture Push Shampoo and L'Oréal Paris Elvive Dream Lengths Curls Moisture Seal Conditioner to hydrate and cleanse your strands


You can also throw a scalp scrub, such as the L’Oréal Paris EverPure Sulfate-Free Scalp Care + Detox Scrub, into the mix beforehand to remove unwanted impurities, excess oil and any product buildup. And if you’re trying to get a few more days out of your style, just reach for a dry shampoo — like the L'Oréal Paris EverPure Sulfate-Free Tinted Dry Shampoo for Dark Tones or Light Tones (depending on the color of your hair) — instead. 


What Is The Right Way To Dye Your Hair At Home?

If you’ve never DIYed your hair color before, using an at-home hair dye can be intimidating.

But when done right, boxed hair dye can deliver a stunning, long-lasting shade you're sure to love. All it takes is the right prep to master coloring your hair in the comfort of your own home. 


Make sure to thoroughly read through the instructions on the box beforehand so you get it right. And of course, if you need more in-depth color advice, the L’Oréal Paris Hair Color Concierge is here to help and provide professional tips, tutorials and advice from expert colorists.
