ARCTIC FOX Poseidon Semi-Permanent Hair Dye — Poseidon Blue 4 fl oz, Vegan Conditioning Ammonia-Free Color

Arctic Fox Poseidon is a semi-permanent, vegan blue hair color cream that deposits a vivid medium blue while conditioning hair without ammonia or peroxide.

If you want a bold, ocean-inspired blue without harsh chemicals, this Poseidon shade from ARCTIC FOX gives intense, long-wearing color while keeping strands soft. The formula is vegan and cruelty-free, designed to work best on pre-lightened hair but also blendable to create custom tones. It suits anyone who wants temporary, vibrant color with conditioning benefits and fewer harmful additives.

How intense will the blue look on my hair?

Poseidon delivers a strong medium-blue payoff on hair lifted to a cool-toned level eight or lighter. On darker hair, expect subtle blue tints or use it over pre-lightened sections for full vibrancy. The shade also responds well to mixing—dilute for pastels or deepen by combining with darker dyes.

• Best results on hair lightened to level 8+ with cool undertones
• Mix with Arctic Mist for pastel baby blue
• Combine with Purple Rain to counter warm brass
• Works as a toner for previously bleached hair

What does the formula do for my hair while coloring?

Beyond pigment, this dye conditions hair during processing, leaving strands feeling softer and less dry than many permanent dyes. It contains no peroxide, ammonia, PPD, ethyl alcohol, or harsh solvents, reducing the risk of brittle texture when used as directed. Expect a pleasant scent and a lower-smell application than oxidizing dyes.

• Vegan ingredients and no animal by-products
• Conditioning agents included for smoother strands
• No peroxide or ammonia—gentler processing
• Reduced odor compared with permanent hair color

How long will Poseidon color last and how should I maintain it?

As a semi-permanent formula, Poseidon fades gradually over weeks depending on washing frequency and hair porosity. To prolong hue, use sulfate-free shampoos, wash with cooler water, and minimize heat styling. Refresh the color by reapplying or mixing a small amount into a conditioner for a quick tone-up.

• Lasts several weeks; lifespan varies by hair type and care
• Use sulfate-free products and cool water to extend wear
• Refresh with low-dose reapplications or color-depositing conditioners
• Avoid daily shampooing to reduce fade

Is Poseidon safe and customizable for different looks?

Yes—Poseidon is formulated without many common harsh ingredients and is suitable for frequent color changes when used responsibly. It mixes easily with other Arctic Fox shades or conditioners to create pastels, deeper blues, or tone down brass. Always perform a patch test and strand test to confirm results on your hair.

• Free from peroxide, ammonia, ethyl alcohol, and PPD
• Blendable with Arctic Mist, Purple Rain, and other shades
• Patch and strand tests recommended before full application
• Good option for creative, temporary color changes
