Check Your Bottles — These Ingredients Can Wreck Color-Treated Hair

If you color your hair, you're going to want to read this. While having a healthy scalp is essential for thriving strands, not all products designed to encourage a hydrated, clean scalp are safe to use on color-treated hair. In fact, certain ingredients found in many of these formulas have the power to strip the color right off your strands.
Don't worry: We consulted hair care experts on how to protect your color and care for your scalp at the same time. Here, a list of ingredients to avoid, along with a few better options.
Ingredients to avoid using on color-treated hair.
While labels like color-safe can be helpful, it's best to be aware of which ingredients you should avoid so you don't accidentally wash away the vibrant hue.

Celebrity stylist, hair expert, and co-founder of dpHue Justin Anderson and hairstylist Gretchen Trukenbrod from Oscar Blandi Salon gave us the inside scoop on exactly what to look out for when buying new hair care products to use on color-treated hair. This includes those who have full head color, highlights, or get root touch-ups.
We'll start with the more obvious culprits: sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), parabens (methylparaben, propylparaben, butylparaben, etc.), alcohols (ethanol or propanol), and sodium chloride (salt). The first two ingredients are types of sulfates. These are frequently used in shampoos because they help create a foamy lather. While satisfying, it's not the best for your hair. These will likely cause your color to wash out and leave you with a faded, dull look.
Parabens should be avoided in general when it comes to hair care products, as they have been shown to build up in the body1
As for the sneakier ingredients that can strip your color, you'll want to look out for clarifying or purifying agents—charcoal, salicylic acid, and the like. That's not to say you can't use a scalp scrub or clarifying shampoo once in a while, but just know that these ingredients can slowly lift the dye from your strands. (And if the product also includes sulfates or salt, the process can happen even quicker.) It's not a huge issue, especially if you opt for permanent dye, but know that a few rounds may fade your color over time.

The takeaway.
It's essential to care for your scalp if you want healthy hair. However, if you have color-treated hair, you'll want to be extra careful when using any sort of clarifying or detoxifying hair products. Be sure to look out for sulfates, parabens, alcohol, and sodium chloride in your products, and if you're looking to pamper your scalp a bit more, try out this scalp massage tutorial for healthy hair growth.
