What I Looked for Before Buying
When I first considered John Frieda Blue Crush, I wanted something that could help reduce brassy orange tones in my brown hair without making it feel dry or dull. My main focus was finding a product that worked well for brunette hair, was easy to use at home, and gave visible results without requiring a salon visit.
Who I Think It’s Best For
In my experience, John Frieda Blue Crush is best for people with brunette hair who want to tone down orange and coppery warmth. I found it especially useful if my hair had been lightened, highlighted, or exposed to sun and heat styling, since those things can make brassiness show up more.
Why I Considered Buying It
I was drawn to this product because it is specifically made for brunettes dealing with unwanted warm tones.

What I’d Watch Out For
I would keep in mind that results can vary depending on my hair color, porosity, and how brassy my hair is to begin with. I also know that toning products can sometimes be drying if I use them too often, so I would pair it with a good conditioner or moisturizing treatment.
My Buying Tips
Before I buy, I always check:

- How often I plan to use it
- Whether I have a hydrating conditioner to balance it out
- If I want a shampoo-only option or a full toning routine
