Why the Best Purple Shampoo for Keratin Treated Hair is Necessary

As someone who has invested in keratin treatments to keep my hair smooth and frizz-free, I quickly learned that maintaining that salon-fresh look requires more than just regular visits to the stylist. One of the best decisions I made was incorporating a high-quality purple shampoo into my hair care routine. The difference it makes is truly remarkable.

First and foremost, purple shampoo is essential for neutralizing unwanted brassy tones that often creep in, especially in lighter shades. After my keratin treatment, I noticed that my blonde highlights tended to look dull and yellow over time. Using purple shampoo helped brighten my hair, keeping those vibrant tones intact and making my overall look much more polished. It’s like a little boost of brightness that transforms my hair from drab to fab!

Additionally, I appreciate how purple shampoo is gentle enough to use on keratin-treated hair without stripping away the treatment’s benefits. Many shampoos can be harsh and lead to quicker fading of that smooth finish I love so much. But with the right purple shampoo, I feel confident that I’m enhancing my color while preserving the keratin treatment, allowing my hair to remain healthy and shiny.

Overall, I can confidently say

My Buying Guides on Best Purple Shampoo For Keratin Treated Hair

As someone who has invested in keratin treatments for my hair, I’ve learned that maintaining that gorgeous, smooth finish requires the right products. One essential item in my hair care routine is purple shampoo. It helps to keep brassiness at bay while ensuring my keratin-treated locks stay vibrant. If you’re on the hunt for the best purple shampoo for keratin-treated hair, let me share my insights and experiences to help you make an informed choice.

Why Use Purple Shampoo?

When I first started using purple shampoo, I was amazed at how it transformed my hair. Purple shampoo neutralizes unwanted yellow and brassy tones, which can be especially prominent in blonde or silver hair. For keratin-treated hair, it’s crucial to use a gentle formula that won’t strip away the treatment while still providing color correction.

Key Ingredients to Look For

When choosing a purple shampoo for my keratin-treated hair, I always look for specific ingredients:

  • Purple Pigments: These are essential for neutralizing brassiness. I prefer shampoos with a balanced amount to avoid overly violet hair.
  • Sulfate-Free Formulas: Sulfates can be harsh and strip away keratin treatments. I opt for shampoos that are sulfate-free to ensure my hair remains smooth and healthy.
  • Moisturizing Agents: Ingredients like argan oil, coconut oil, or shea butter help keep my hair hydrated and prevent dryness, which is crucial after a keratin treatment.

Top Picks for Purple Shampoo

Based on my personal experiences and research, here are my top picks for the best purple shampoo for keratin-treated hair:

  1. Fanola No Yellow Shampoo

I’ve found that this shampoo has a strong purple pigment that effectively neutralizes brassiness. It’s sulfate-free, making it safe for my keratin-treated hair, and leaves my locks feeling soft and manageable.

How to Use Purple Shampoo Effectively

To get the best results from my purple shampoo, I follow these simple steps:

  1. Wet Your Hair: I start by wetting my hair thoroughly.
  2. Apply Shampoo: I apply a generous amount of purple shampoo, focusing on the lengths and ends where brassiness is most prevalent.
  3. Let It Sit: I usually let it sit for 3-5 minutes. This allows the purple pigments to work their magic.
  4. Rinse and Condition: After rinsing out the shampoo, I follow up with a good conditioner to keep my hair hydrated.

Final Thoughts

Finding the right purple shampoo for my keratin-treated hair was a game changer. It’s important to choose a product that not only neutralizes brassiness but also respects the integrity of the keratin treatment. By considering the ingredients and following my recommended usage tips, I’m confident you’ll find a purple shampoo that suits your needs.
