Polar Hair Purple Semi-Permanent Hair Dye Shampoo for Gray Hair — 6.76 fl oz, Ammonia-Free Toning & Conditioning

Polar Hair Purple Hair Dye Shampoo is an ammonia-free, vegan semi-permanent shampoo that tones, cleanses, and helps camouflage gray in about 10 minutes.

Designed for both women and men, this 3-in-1 purple shampoo combines gentle cleansing, conditioning, and color deposition to neutralize brassiness and blend gray strands without harsh chemicals. Its plant-forward formula aims to leave hair feeling hydrated and looking cooler-toned for weeks after application.

How quickly will I see color and gray coverage?

Visible toning and gray blending can appear after a single 10-minute application, with results developing more fully across repeated uses. Because it’s semi-permanent, the intensity depends on your starting hair shade and how often you shampoo.

• Apply 10 minutes for an initial tone and subtle coverage.
• Use 1–3 times weekly to deepen color and blend more gray.
• Expect the tone to mellow gradually over 4–6 weeks with regular washing.

Will this damage my hair or is it safe for color-treated hair?

The formula is ammonia-free and vegan, designed to be milder than permanent dyes. It cleanses and deposits pigment while including conditioning agents to minimize dryness, making it suitable for many color-treated and chemically treated hair types.

• No ammonia or harsh oxidizers in the blend.
• Conditioning ingredients help reduce breakage and frizz.
• Patch or strand test first if you have very porous or heavily processed hair.

How do I use it for best results at home?

Massage into wet hair, leave on for around 10 minutes, then rinse thoroughly. For deeper purple tone or more gray blending, increase frequency to a few times weekly or leave a minute or two longer, watching color development closely.

• Work through roots to tips on shampooed, towel-dried hair.
• Comb through for even pigment distribution.
• Rinse until water runs clear to avoid staining fabrics.

How long will the purple tone last and how should I maintain it?

Color longevity varies by hair porosity and washing routine, but you can expect a noticeable purple tone for up to six weeks with gentle maintenance. Use color-safe shampoos, cool water, and limit heat styling to extend vibrancy.

• Avoid daily hot-water washes to slow color fade.
• Pair with sulfate-free, color-safe products for longer wear.
• Refresh with the purple shampoo 1–2 times weekly as needed.

Who this is for: Polar Hair Purple Hair Dye Shampoo suits anyone looking to tone brassiness, soften the look of grays, or add a cool purple cast without committing to permanent dye. It’s a practical option for people with natural, highlighted, or previously colored hair who prefer a gentler, multi-action product that cleanses, conditions, and deposits color in one step.
