Best Non-Permanent Blue Hair Dye Options for Temporary Color
For blue hair color without a permanent commitment, choose a washable spray for quick, one-day color or a styling wax for color and hold. For a longer-lasting temporary tint, a color-depositing conditioner may be a better fit. The options below include picks for costumes, kids and teens, and people seeking a deeper blue shade. Check the product directions and test a small section first, especially if you are unsure how the color will look on your hair.
| Product | Format | Best For |
|---|---|---|
| EFLY Temporary Blue Hair Color Wax | Color wax | Temporary color with styling |
| Four-Color Temporary Hair Color Wax | Four-color wax set | Trying multiple shades |
| L’Oréal Colorista Blue Spray | Washable spray | One-day events |
| INH Royal Sapphire Color | Color-depositing conditioner | A deeper, semi-permanent tint |
| Waybesty Blue Hair Color Spray | Washable spray | Quick application |
EFLY Temporary Blue Hair Color Wax

Best for: People who want temporary blue color while shaping or defining a hairstyle. This wax is intended to add vivid color and styling hold, making it a practical choice for parties, cosplay, festivals, Halloween, or everyday experimentation.
The listed formula includes plant extracts, honey, and olive oil. It is described as washable and as a way to change color without committing to permanent dye. The wax format may suit buyers who want color and styling in one product rather than a spray alone.
Limitation: Wax is a styling product, so it may not be the best choice if you only want a light mist of color without added hold.
Four-Color Temporary Hair Color Wax

Best for: Families or anyone who wants to switch between several temporary shades. The listing identifies blue, green, purple, and red wax, so it offers more color choices than a single-blue product. It is designed to color and style hair and is described as easy to wash out.
The listed ingredients include beeswax, licorice extract, tea extract, and castor oil. Its multiple shades make it a flexible option for costumes, themed events, and creative hairstyles. The listing says it is intended for adults and children.
Limitation: This is a multi-color wax product, not a blue-only dye. Choose a single-color option if you do not need the other shades.
L’Oréal Colorista Blue Spray

Best for: Buyers who want an easy-to-apply blue shade for a one-day event. This 2-ounce spray is described as quick to apply and designed to wash out after one day of wear. It is positioned for costumes, sporting events, music festivals, and themed parties.
The listing says the spray works on all hair types and does not require bleach. That makes it a straightforward option for trying a vivid shade without starting a permanent coloring process. Choose this format if speed and short wear time matter more than styling hold.
Limitation: It is designed for one-day wear, so it is not the pick for a tint intended to last through multiple washes.
INH Royal Sapphire Color-Depositing Conditioner

Best for: Buyers seeking a dark blue, semi-permanent tint in a conditioner format rather than a quick costume spray. The product title names Royal Sapphire and describes it as a color-depositing conditioner. The listing says the ready-to-use formula does not require mixing with developer or lightener.
The listed directions say to leave the product on for 30–60 minutes, then rinse with cool or lukewarm water. The title describes it as vegan and free of ammonia and sulfates. This is the better option for someone willing to spend more time applying color than a spray requires.
Limitation: The provided feature text refers to red color, despite the product title identifying dark blue Royal Sapphire. Verify the shade and current product details before buying.
Waybesty Temporary Blue Hair Spray

Best for: People who want a larger-format spray and fast application for parties, costumes, or short-term style experiments. The listing describes a 4.06-ounce blue spray with a fast-drying formula, and says it rinses out with one shampoo.
The product is presented as suitable for all hair types and children’s hair. The listing also says it is intended to avoid a sticky residue. Choose this spray if you prefer applying color by misting rather than working wax through the hair.
Limitation: The listing provides no specific wear duration beyond saying it rinses out with shampoo, so it may not suit buyers who need a precise one-day guarantee.
Buying Guide: How to Choose Non-Permanent Blue Hair Dye
Do you want color for one day or longer?
For a short event, a washable spray is the most direct match: L’Oréal describes one-day wear, while Waybesty says the color rinses out with shampoo. Wax is also temporary, but adds styling hold. A color-depositing conditioner is a better fit if you want a tinting process rather than quick event color; check its shade details and directions before use.
Should you choose a spray, wax, or conditioner?
- Spray: Choose it for quick application and a color-only styling change.
- Wax: Choose it if you want temporary color alongside hairstyle definition or hold.
- Color-depositing conditioner: Choose it if you prefer a ready-to-use product applied for a set period before rinsing.
What should you check before applying blue color?
Review the instructions, shade name, and removal method. If the listing details conflict—as they do for the INH shade information—confirm the product’s current label before purchase. A small test section can help you judge the result and removal process before applying color more broadly. Follow any product-specific precautions, particularly when applying color to children’s hair.
