Unicorn hair dye has become a wildly popular way to achieve fun, fantasy-inspired hair colors at home. But to get the most vibrant, long-lasting results from these semi-permanent dyes, proper application and processing time is key.
So how long should you leave unicorn hair dye in for optimal color payoff? Here’s a detailed look at recommended processing times and tips for maximizing the brilliance of your unicorn hair hue.
Overview of Processing Time for Unicorn Hair Dye
The recommended processing time for unicorn hair dye depends on a few factors:
- For standard results, leave in for 30-45 minutes
- For more intense, saturated color, process for 1-2 hours
- Finer, thinner hair may need less time than thick, coarse hair
- Pre-lightened hair will pick up more vivid color than darker bases
- Pastel unicorn colors require shorter time than brighter shades
- Follow instructions on the specific brand and formula you use
In general, unicorn hair dyes without developer do not require heat or caps to process. But leaving them on longer, especially on pre-lightened hair, will allow more saturation.
Now let’s look more in-depth at processing techniques and tips for maximizing the longevity and intensity of your unicorn hair color!
Standard Processing Time
Most unicorn hair dye brands recommend leaving the formula in for 30 to 45 minutes to achieve standard results.
This allows enough time for the semi-permanent color to adequately penetrate and deposit within the hair strand without over-processing.
For unicorn hair dyes without bleach or developer, this timeframe is typically sufficient to achieve a nice tint of fantasy color that lasts 4-8 weeks with proper maintenance.
Using no heat during processing makes it gentle enough for frequent touch-ups.
Go Longer for Maximum Color Intensity
While 30-45 minutes delivers noticeable color, going longer will provide more intense, saturated results.
Leaving unicorn hair dye in for 1 to 2 full hours gives the pigments more time to thoroughly push into the hair shaft.
This longer processing time is especially key for achieving vivid brightness on pre-lightened blonde and platinum bases.
The lighter your base, the better unicorn shades will “grab” and show up truer to tone.
Even if you have medium blonde to light brown hair, longer processing will help unicorn colors reach their full potential.
Finer Hair May Need Less Time
Those with thinner, finer, more porous hair may find 20-30 minutes is adequate processing time.
The color develops quicker compared to thicker, coarser hair types.
Play it by ear and check for saturation at 20 minutes first before deciding if you need the full time.
Consider Your Chosen Shade
Vibrant unicorn shades with intense pigmentation like blues, greens and hot pinks require more time to really take hold than lighter pastel hues.
Bolder unicorn colors will likely need the full 1-2 hours while softer pastels may only need 30-45 minutes.
Again, checking saturation and tones at intervals will help you gauge the right timing for the particular color and your hair type.
Follow Your Brand’s Instructions
While the above serves as a helpful general guideline, always defer to the instructions of the specific unicorn hair dye brand you are using.
There can be some variability between product formulations when it comes to ideal processing times.
For instance, certain unicorn dyes may incorporate some subtle lifting agents or conditioners that impact time needed.
Consult the brand’s guidance for their recommended minimum to maximum timing to ensure ideal results.
Tips for Maximizing Processing Effectiveness
Here are some handy tips to help you get the most out of processing unicorn hair dye for stunning color results:
- Work in 1 inch sections to fully saturate strands
- Apply dye from roots to ends methodically
- Massage dye into each section as you go
- Use clips to keep sections separated
- Set a timer to avoid surprises
- Strand test first to assess timing needs
- Have a hair dyeing cape or old shirt ready
- Rinse with lukewarm water afterwards
- Use color-safe shampoo and conditioner
Taking your time with application and adhering to timing recommendations will allow you to achieve the most brilliant, eye-catching unicorn hair hue possible!
Can I Leave Unicorn Hair Dye In Overnight?
Technically, yes – leaving unicorn hair color in overnight is an option since most contain gentle, conditioning formulas.
However, doing so is not necessary and provides minimal added benefit in terms of color intensity.
The saturation will mostly max out after 1-2 hours.
Overnight processing runs the (small) risk of over-depositing too much pigment, leading to an uneven or splotchy look.
Stick to the recommended 1-2 hours for best control over your final results.
Will Unicorn Hair Dye Damage My Hair if Left In Too Long?
The great news about unicorn hair dyes is that they are formulated to be conditioning rather than damaging.
These semi-permanent dyes do not contain harsh bleaches, peroxides or ammonia.
Therefore, leaving unicorn hair color in a bit longer than suggested will not damage the hair.
However, as mentioned above, over-processing can make the color outcome less even.
So for best results, don’t go too far beyond the max recommended time.
Do You Need Heat When Processing Unicorn Hair Dye?
Using heat is not necessary when processing unicorn hair colors without developer.
The gentle formulas allow saturation without excessive drying or damage.
If anything, a heated cap could over-accelerate pigment uptake leading to uneven results.
Stick to room temperature processing to be safest and let the color develop gradually.
Can I Speed Up Processing with Heat?
It’s best not to use any heat when applying unicorn hair dyes like Manic Panic, Lime Crime, etc.
These are deposit-only formulas not requiring developer or lightning.
While heat may hasten processing, it runs the risk of creating an uneven end result.
For unicorn hair colors, patience pays off – slow and steady color development is best!
How Soon Can I Wash Out Unicorn Hair Dye?
Ideally, unicorn hair dye should remain in the hair for the full recommended processing time for best saturation.
However, if needed, you technically can rinse the color out sooner than suggested.
Bear in mind color intensity and longevity may be reduced with shorter processing.
Follow up with occasional color-depositing conditioner to boost the tone.
What Factors Affect Processing Time?
Key factors impacting processing time for unicorn hair dye include:
- Hair thickness – coarser hair may need longer
- Existing hair color – pre-lightened absorbs more vibrancy
- Color chosen – pastels require less time than neon brights
- Type of formula – conditioning vs. damaging
- Your hair’s condition – dry, damaged hair takes quicker
- Following brand guidance – their suggested time range
Consider all these variables when deciding on your unicorn hair dye processing time.
Can I Reapply Unicorn Hair Dye Without Washing?
It’s not recommended to reapply unicorn hair dye on top of unfinished dried dye.
For the best result, thoroughly shampoo out the first application then re-dye on clean hair.
Trying to layer more dye without washing just increases risk of uneven buildup.
Stick to one complete application for a smooth, even unicorn hair result.
Maintain Your Unicorn Hair Color
To keep your unicorn hair looking magical between applications:
- Use sulfate-free, color-safe shampoo
- Condition often with hair masks or treatments
- Refresh color with a color-depositing conditioner
- Wash less frequently if possible
- Protect from chlorine, salt water and sun exposure
- Avoid heat styling when you can
Follow good aftercare habits to extend your unicorn hair color life span!
