John Frieda Blue Crush Shampoo & Conditioner Set for Brunettes, 2-Pack 8.3 oz — Neutralizes Brassiness, Color-Safe

John Frieda Blue Crush Shampoo and Conditioner Set refreshes brunette color by neutralizing brassiness with blue pigments for cooler, brighter hair.

If your brown hair is showing warm, brassy tones after coloring or sun exposure, this two-step Blue Crush system is formulated to rebalance and enhance cool brunette shades. The shampoo deposits crushed blue pigments and uses a tri-dye blend plus a dual penetration system to target faded areas while minimizing staining on skin. The companion conditioner boosts shine and smooths strands with targeted conditioning and polyol technology, leaving hair more manageable without peroxide or ammonia.

How quickly will I see a difference in brassiness?

Many users notice reduced brassiness after a single wash thanks to the concentrated blue pigments that neutralize unwanted warm tones. Results depend on hair porosity, starting color, and how long the product is left on the hair.

• Visible toning often in one use for mild brassiness.
• Stronger or very brassy hair may need a few treatments spaced several washes apart.
• Best results when followed by the Blue Crush conditioner to seal and smooth.

Will this set stain my skin or bathroom surfaces?

The formula uses a tri-dye blend and a dual penetration system designed to maximize pigment uptake in hair while minimizing skin transfer. That reduces the chance of noticeable staining on your hands or sink during application.

• Tri-dye blend helps pigments go into strands, not onto skin.
• No need for gloves in most cases, though caution is advised with very porous skin.
• Wipe any excess immediately to avoid temporary residue on surfaces.

Is this safe for color-treated and natural brunette hair?

Yes — the shampoo and conditioner are peroxide- and ammonia-free, formulated for both dyed and natural brown hair. The conditioner restores and targets damaged areas while increasing shine without stripping or lightening existing color.

• Peroxide-free, ammonia-free formulation suitable for maintaining color vibrancy.
• Conditioner uses targeted conditioning to support fragile, highlighted, or processed hair.
• Designed to complement color services by slowing visible fading and brassiness.

How should I use the Blue Crush system for best effect?

Use the shampoo to cleanse and deposit blue pigments, focusing on high-fade zones like ends or highlighted pieces. Follow with the conditioner to smooth cuticles, boost shine, and reinforce the tone correction.

• Apply shampoo, lather, and leave on a short time if you need extra toning, then rinse.
• Apply conditioner primarily to mid-lengths and ends; leave a minute before rinsing.
• Adjust frequency—use weekly or as needed based on brassiness and maintenance routine.
