Lime Crime Unicorn Hair Dye Instructions: A Comprehensive Guide

Lime Crime Unicorn Hair offers vibrant, fantastical colors with a vegan and cruelty-free formula, ideal for pre-lightened hair. This guide details application,
care, and troubleshooting for stunning results, ensuring a magical hair transformation.
Understanding Lime Crime Unicorn Hair
Lime Crime Unicorn Hair distinguishes itself within the hair dye market as a semi-permanent option, celebrated for its commitment to both vegan and cruelty-free practices. Unlike traditional permanent dyes, Unicorn Hair avoids harsh chemicals like ammonia and peroxide, minimizing potential damage to your hair’s natural structure. This makes it a popular choice for those seeking vibrant color changes without long-term commitment or significant hair stress.
The dye’s formulation focuses on depositing highly saturated color, working best on hair that has been pre-lightened to platinum or medium blonde shades. While it can impart a tint to darker blonde or light brown hair, achieving truly vivid results necessitates a lighter base. It’s important to remember that the longevity of the color is influenced by the specific shade chosen, the initial condition of your hair, and the frequency of washing.
Lime Crime emphasizes quality, designing, manufacturing, and assembling its products with globally sourced ingredients to ensure high performance and strong color payoff. The brand’s dedication to ethical practices is validated through certifications from both Leaping Bunny and PETA.
What is Unicorn Hair?
Lime Crime Unicorn Hair is a semi-permanent hair dye renowned for its exceptionally vibrant and magical color range. It’s designed to deposit intense, saturated pigments onto pre-lightened hair, transforming it into a spectrum of fantastical shades. The formula isn’t about lifting or bleaching; it’s about layering rich color onto a suitable base.

This dye stands out due to its conditioning properties, aiming to leave hair feeling soft and manageable even after coloring. It’s a favorite among beauty enthusiasts for its ease of use and the creative freedom it allows. The product’s popularity surged thanks to its unique color selection and the brand’s impactful social media presence, fostering a community of vibrant self-expression.

Unicorn Hair is more than just a dye; it’s a statement. It allows individuals to experiment with bold, eye-catching looks without the permanence of traditional hair coloring methods. The brand consistently delivers high-quality, on-trend colors, making it a go-to for those seeking a temporary, yet impactful, hair transformation.
Semi-Permanent vs. Permanent Dye

Understanding the difference between semi-permanent and permanent hair dye is crucial before using Lime Crime Unicorn Hair. Permanent dyes utilize chemicals like ammonia and peroxide to alter the hair’s structure, permanently changing its color. They penetrate the hair shaft, resulting in a lasting effect, but also potential damage.
Unicorn Hair, being semi-permanent, operates differently. It lacks ammonia and peroxide, instead coating the hair shaft with color molecules. This means it doesn’t cause lasting structural changes, making it gentler on the hair. The color gradually fades with each wash, typically lasting anywhere from a few washes to several weeks, depending on hair porosity and color vibrancy.
Semi-permanent dyes are ideal for those wanting to experiment with color without commitment; They’re less damaging and allow for frequent color changes. However, they require a lighter base for the color to truly show, and the results aren’t as long-lasting as permanent dyes. Lime Crime emphasizes this, recommending pre-lightened hair for optimal results.
Vegan and Cruelty-Free Formula
Lime Crime Unicorn Hair proudly boasts a completely vegan and cruelty-free formula, appealing to ethically conscious consumers. This means no animal-derived ingredients are used in the dye’s production, aligning with a plant-based lifestyle. The brand actively avoids ingredients sourced from animals or those tested on animals.
Furthermore, Lime Crime is officially certified by both Leaping Bunny and PETA, demonstrating a strong commitment to cruelty-free practices. These certifications signify that the entire production process, from ingredient sourcing to final product assembly, adheres to rigorous standards prohibiting animal testing.
This dedication extends to the quality of the dye itself. Lime Crime designs, manufactures, and assembles its products using globally sourced ingredients, prioritizing high performance and strong color payoff. You can enjoy vibrant, fantastical hair color knowing it’s created with compassion and care, free from harsh chemicals like PPD, peroxide, and ammonia.
Preparing for Application
Successful Lime Crime Unicorn Hair application requires careful preparation. Always perform a strand and patch test first, and ensure your hair is properly lightened for optimal results.
Strand Test: Why It’s Crucial
Before diving into a full-head application of Lime Crime Unicorn Hair, a strand test is absolutely non-negotiable. This seemingly small step can save you from potential color disappointments and unexpected results. The strand test allows you to preview how the dye will interact with your specific hair texture, porosity, and existing color – factors that significantly influence the final outcome.
Here’s how to conduct a proper strand test: select a small, inconspicuous section of your hair – perhaps underneath, near the nape of your neck. Apply the Unicorn Hair dye to this section, following the instructions as you would for a full application. Process the dye for the recommended time, then rinse and dry the strand.
Carefully evaluate the color achieved. Is it the shade you expected? Is the color payoff vibrant enough? Does your hair feel damaged or overly dry? The strand test reveals if your hair needs further lightening or if adjustments to the processing time are necessary. Remember, results can vary, and this test is your safeguard!
Patch Test: Ensuring No Allergic Reaction
Prior to applying Lime Crime Unicorn Hair dye to your scalp, performing a patch test is essential to rule out any potential allergic reactions or skin sensitivities. Even though Unicorn Hair boasts a vegan and cruelty-free formula free of harsh chemicals like PPD, peroxide, and ammonia, individual reactions can still occur. Protecting your skin’s health is paramount.
To conduct a patch test, apply a small amount of the dye to a discreet area of skin – behind your ear or on the inside of your elbow are good choices. Leave the dye on for the recommended processing time, then rinse thoroughly with water. Observe the area for 48-72 hours.
Watch for any signs of irritation, such as redness, itching, burning, swelling, or blistering. If you experience any of these symptoms, discontinue use immediately and consult a healthcare professional. A patch test is a simple precaution that can prevent significant discomfort and ensure a safe and enjoyable coloring experience with Lime Crime.
Hair Preparation: Lightening Your Hair
Lime Crime Unicorn Hair is a semi-permanent dye that deposits color, meaning it doesn’t lift or lighten your existing hair color. For the most vibrant and true-to-tone results, especially with lighter shades, pre-lightening your hair is crucial. The dye works best on platinum to medium blonde hair, adding a tint to dark blonde or light brown hair, but the color payoff will be significantly reduced on darker bases.
If your hair is naturally dark, you’ll need to bleach it to achieve a pale blonde shade before applying Unicorn Hair. This process can be damaging, so it’s recommended to seek professional assistance from a qualified hair stylist. They can assess your hair’s health and use appropriate lightening techniques to minimize damage.
Ensure your hair is healthy and well-conditioned after lightening. Deep conditioning treatments are vital to restore moisture and strength before applying the dye. Remember, the lighter and healthier your base, the more vivid and long-lasting your Lime Crime color will be!
Gathering Your Supplies
Before embarking on your Lime Crime Unicorn Hair transformation, meticulous preparation is key! Assemble the following supplies for a smooth and successful dyeing experience. You’ll need your chosen Unicorn Hair shade(s), gloves (included in the kit, but extras are helpful!), an old towel or cape to protect your clothing, and a mixing bowl – avoid metal, as it can react with the dye.
Sectioning clips are essential for organized application, ensuring even coverage. A wide-tooth comb will help distribute the dye through your hair. Petroleum jelly or a barrier cream is vital to protect your hairline, ears, and neck from staining. Have a timer readily available to accurately track processing time.
Don’t forget a color-safe shampoo and conditioner for post-dye care, and a deep conditioning treatment to maintain hair health. Finally, have paper towels or old rags on hand for quick cleanup of any spills. Being fully prepared minimizes stress and maximizes your vibrant results!

The Dyeing Process
Applying Lime Crime Unicorn Hair involves precise sectioning, even dye distribution, and careful timing. Follow the instructions closely for optimal color payoff and a vibrant, magical result!
Application Technique: Sectioning Your Hair
Proper hair sectioning is crucial for even Lime Crime Unicorn Hair dye distribution and achieving a consistent, vibrant color. Begin by parting your dry, pre-lightened hair down the middle, creating two equal sections. Then, divide each of those sections in half again, resulting in four quadrants.
For thicker hair, further subdivide each quadrant into smaller, more manageable sections – approximately one inch wide. Use clips to securely hold each section in place, preventing them from mixing with others during application. This meticulous approach ensures every strand receives adequate dye coverage.
Working with smaller sections allows for precise application, minimizing missed spots and promoting a uniform color result. Remember to label each section if needed, especially for complex color designs. Consistent sectioning is the foundation for a flawless Unicorn Hair transformation, maximizing the dye’s potential and minimizing color inconsistencies.
Applying the Dye: Even Distribution
Applying Lime Crime Unicorn Hair requires a generous and even application for optimal color payoff. Wearing gloves is essential to protect your hands from staining. Start with one section, and using a dye brush, saturate the hair completely from root to tip. Ensure every strand is thoroughly coated – this is key for vibrant results!
Massage the dye into the hair, working it in gently to guarantee full saturation. Avoid clumping or pooling of the dye; consistent coverage is paramount. Repeat this process for each section, systematically working your way around the head.
For best results, apply a generous amount of dye, especially to porous or previously damaged hair. Once all sections are covered, gently comb through your hair to distribute the dye evenly and remove any remaining clumps. This meticulous approach ensures a uniform, head-turning color that truly embodies the Unicorn Hair magic.
Processing Time: How Long to Leave It In
Lime Crime Unicorn Hair processing time significantly impacts color vibrancy. Generally, leaving the dye on for 30-60 minutes yields beautiful results, but adjustments can be made based on your hair’s porosity and desired intensity. For more stubborn or darker hair, extending the processing time up to 90 minutes can enhance color deposit.
However, avoid exceeding 90 minutes, as prolonged exposure won’t necessarily increase color intensity and could potentially cause dryness. During processing, consider wrapping your hair in plastic wrap or a shower cap to maintain heat and prevent dripping. This helps the dye penetrate the hair shaft more effectively.
Regularly check a small strand to monitor color development. Remember, individual results vary, so observing your hair’s response is crucial. The longer the dye remains, the more noticeable the color will be, but always prioritize hair health and avoid over-processing.
Rinsing and Conditioning
Rinsing Lime Crime Unicorn Hair requires cool water until the water runs almost clear – avoid warm or hot water, as it can accelerate fading. This process can take several minutes, ensuring all dye residue is removed. Don’t shampoo your hair immediately after rinsing; this allows the color to fully set and minimizes bleeding.
Following the rinse, apply a generous amount of conditioner specifically formulated for color-treated hair. Lime Crime recommends a deep conditioner to replenish moisture lost during the dyeing process and seal the hair cuticle, locking in the vibrant color. Leave the conditioner on for 3-5 minutes before thoroughly rinsing again with cool water.
This step is vital for maintaining hair health and preventing dryness. Avoid using harsh sulfates or alcohol-based products during your first few washes to prolong the life of your new color. A final cool water rinse will further enhance shine and color vibrancy.
Post-Dye Care & Maintenance
Maintaining Lime Crime Unicorn Hair involves color-safe shampoos, avoiding heat, and deep conditioning; Protect your investment with proper care for long-lasting vibrancy and healthy hair!
Washing Your Hair: Color-Safe Shampoo
Choosing the right shampoo is paramount after dyeing your hair with Lime Crime Unicorn Hair. Traditional shampoos often contain harsh sulfates that strip away vibrant color molecules, leading to premature fading. Opt for a shampoo specifically formulated for color-treated hair; these are typically sulfate-free and designed to gently cleanse without diminishing the dye’s intensity.
Frequency matters too. Washing your hair less often will significantly prolong the life of your color. Consider extending the time between washes to every 2-3 days, or even longer if possible. When you do wash, use cool or lukewarm water, as hot water opens the hair cuticle, allowing color to escape.
Look for shampoos with nourishing ingredients like argan oil or shea butter to help hydrate and strengthen your hair. These ingredients can also help to seal the cuticle, locking in color. Avoid clarifying shampoos, as they are designed to remove buildup and will also remove dye. Investing in a quality color-safe shampoo is a small price to pay for maintaining the vibrancy of your Unicorn Hair!
Avoiding Fading: Protecting Your Color
Protecting your vibrant Lime Crime Unicorn Hair requires consistent effort beyond just color-safe shampoo. Minimize sun exposure, as UV rays are notorious for fading hair color. When outdoors for extended periods, wear a hat or use a hair product containing UV protection.
Heat styling should be limited. Frequent use of blow dryers, curling irons, and straighteners can damage the hair cuticle and cause color to fade faster. Always use a heat protectant spray before applying heat. Consider air-drying your hair whenever possible to minimize damage.
Chlorine and saltwater are also color enemies. Before swimming, wet your hair with clean water and apply a leave-in conditioner to create a barrier. After swimming, rinse your hair thoroughly to remove any traces of chlorine or salt. Regular deep conditioning treatments will help replenish moisture and keep your color looking fresh. Prioritize gentle handling and mindful practices to preserve your magical hue!
Deep Conditioning: Maintaining Hair Health
Lime Crime Unicorn Hair, while conditioning, benefits greatly from regular deep conditioning treatments. Semi-permanent dyes, even those without harsh chemicals, can still slightly alter the hair’s porosity. Deep conditioning replenishes lost moisture and helps seal the cuticle, locking in color and enhancing shine.
Aim for a deep conditioning treatment at least once a week, or more frequently if your hair is particularly dry or damaged. Look for masks specifically formulated for color-treated hair, containing ingredients like argan oil, shea butter, or keratin. Apply the mask generously, focusing on the ends, and leave it on for the recommended time – often 10-20 minutes – under a shower cap for enhanced penetration.
Consider using a protein treatment occasionally to strengthen the hair shaft, especially if you frequently lighten or style your hair. Healthy hair holds color better and is less prone to breakage, ensuring your vibrant shade lasts longer and looks its best.

Dealing with Previously Dyed Hair
Using Lime Crime Unicorn Hair on previously dyed hair requires careful consideration, as the outcome can vary significantly. The existing color’s type and shade heavily influence the final result. If the prior dye is similar or lighter than your desired Unicorn Hair shade, predictability increases, offering a more accurate color deposit.
However, darker previously dyed hair presents challenges. The new color might not show up vibrantly, or could be altered by underlying pigments. A strand test is crucial in these cases to assess compatibility and potential color interactions. You may need to lighten the existing color further to achieve the desired vibrancy, but proceed cautiously to avoid damage.
Be aware that porous hair (often from previous bleaching) absorbs color quickly, potentially leading to uneven results. Applying a protein filler before dyeing can help even out porosity. Always prioritize hair health and avoid over-processing.

Troubleshooting & FAQs
Lime Crime Unicorn Hair issues like uneven color or staining are common. Strand tests help prevent problems, while color-safe products maintain vibrancy. Consult FAQs for solutions!
Color Not Showing Up: Common Causes
Several factors can contribute to Lime Crime Unicorn Hair dye failing to deposit color effectively. The most frequent culprit is insufficient lightening of the hair. This semi-permanent dye requires a platinum to medium blonde base to showcase its true vibrancy; darker hair simply won’t provide enough contrast for the pigment to be visible.
Another common issue is porosity. Hair that is damaged or overly porous may not retain the dye properly, leading to a faded or non-existent result. Conversely, hair with a tight cuticle might resist dye absorption. A strand test is crucial to assess your hair’s porosity before full application.
Furthermore, the condition of your hair plays a role. Buildup from previous products – silicones, oils, or even hard water minerals – can create a barrier preventing the dye from penetrating the hair shaft. Thoroughly clarifying your hair before dyeing is essential. Finally, ensure you’re using enough product and allowing sufficient processing time, as outlined in the instructions, for optimal color deposit.
Uneven Color: Tips for Correction
Achieving an even application with Lime Crime Unicorn Hair is key, but sometimes streaks or patchy results occur. If you notice uneven color, don’t panic! The first step is to assess the severity. For minor inconsistencies, a second, targeted application to the lighter areas can often balance the tone. Ensure thorough saturation during this touch-up.
If the unevenness is significant, consider a color filler. This helps to create a more uniform base before reapplying the desired shade. Remember to strand test any corrective measures first! Proper sectioning during the initial application is crucial for preventing unevenness; work in small, manageable sections, ensuring complete coverage;
Avoid overlapping dye onto previously colored areas excessively, as this can lead to darker, more intense patches. Finally, remember that previously dyed hair can react unpredictably, so careful consideration and a strand test are vital for successful correction and a beautifully blended result.
Staining Skin and Surfaces: Prevention and Removal
Lime Crime Unicorn Hair’s vibrant pigments can temporarily stain skin and surfaces. Prevention is paramount: wear gloves throughout the application process and protect your work area with old towels or plastic sheeting. Apply a barrier cream (like petroleum jelly) along your hairline and ears to prevent skin staining.
If dye does come into contact with your skin, immediate action is best. Gently wash the area with soap and water. For stubborn stains, a mild oil-based cleanser or makeup remover can be effective. Avoid harsh scrubbing, which can irritate the skin. On surfaces, wipe up spills immediately with a damp cloth.
For more persistent surface stains, try a magic eraser or a diluted bleach solution (test in an inconspicuous area first!). Remember to thoroughly ventilate the area when using any cleaning products. Careful preparation and swift cleanup will minimize staining and ensure a stress-free dyeing experience.
