What Poseidon looks like
Poseidon is a true medium blue, not teal or navy. On platinum hair it is vivid and electric. On darker blonde it deepens to a rich blue. It fades through pretty pastel blue stages. The color is unmistakable and bold.
4oz vs 8oz bottles
Four ounces suits short hair or root touch-ups. Eight ounces covers medium to long hair. Thick hair may need two bottles. Buying the larger size saves money. When unsure, buy more than you think you need.
Poseidon vs Aquamarine
Poseidon is a true blue with no green. Aquamarine is a blue-green teal shade. Poseidon suits those wanting pure blue. Aquamarine suits mermaid looks. They mix beautifully for custom shades.
Pre-lightening requirements
Poseidon needs level 9 to 10 blonde for true color. Darker bases mute it to deep blue-green. Bleach evenly to avoid patchiness. Tone out yellow before applying. The base determines the final result more than the dye.
Vegan and gentle formula
Arctic Fox is 100 percent vegan and cruelty-free. The dye conditions while it colors. It contains no peroxide or ammonia. Hair often feels softer after dyeing. The gentle formula suits frequent color changers.
Making the color last
Wash with cold water and sulfate-free shampoo. Wash less often to slow fading. Use color-depositing conditioner between dyes. Avoid heat styling when possible. Vivid blues typically last three to six weeks.
