My Moroccan Oil Purple Shampoo Review: Eliminates Brassiness Instantly!

I WISH I took a before picture.. I messed up my hair trying to go from brown to blonde, long story short my mother in law helped me fix my hair but i still had slight warm and brassy tones, I bought this product after many many other purple shampoos I've used in the past have failed me. I have used other products of Moroccan Oil just not the purple shampoo and they've all been AMAZING so if any shampoo would work, I know this one wouldn't let me down and boy it has not!! It's exceeded my expectations and I will forever only use this one now! Just after one use I can tell a huge difference in tone, I can't wait to use it again!!

Shampoo Basics & Tips

What is Purple Shampoo?

Purple shampoo is a specialized toning product used primarily for blonde, silver, or highlighted hair. It contains violet pigments that counteract yellow and brassy tones based on color theory—purple neutralizes yellow because they are complementary colors on the color wheel. This helps maintain a cool, bright hair color between salon visits.

Why Hair Turns Brassy After Bleaching

When hair is bleached from a darker shade like brown to blonde, the process strips away melanin, revealing underlying warm pigments such as orange and red. These can appear as unwanted brassy tones if not properly managed. Factors like water quality, sun exposure, or previous hair treatments can exacerbate brassiness.

How Moroccan Oil Purple Shampoo Works

Based on the user's review, Moroccan Oil Purple Shampoo likely combines purple pigments with nourishing ingredients like argan oil to tone hair while conditioning. It effectively neutralizes brassiness with minimal effort, as reported after just one use, and may include UV protection to prevent future discoloration.

Benefits of Using Purple Shampoo

Regular use can extend the life of color-treated hair, reduce the need for frequent salon appointments, and improve hair shine. It's particularly beneficial for those with blonde or gray hair to maintain a fresh, vibrant look.

Common Mistakes When Using Purple Shampoo

Overuse can lead to purple or gray tints on hair. It's best applied once or twice weekly, left on for 2-5 minutes, and followed by a moisturizing conditioner. Always do a patch test first to avoid uneven results.

FAQs About Shampoo for Blonde Hair

How often should I use purple shampoo? Typically, 1-2 times per week depending on hair porosity. Can it damage hair? No, when used correctly, it's safe, but overuse may cause dryness. What if I have dark hair? Purple shampoo is less effective on dark hair but can be used for highlights. How to choose the right product? Look for sulfate-free formulas with added hydrators like those in Moroccan Oil to protect hair health.
