Hair coloring has long gone from its old purpose of covering the grays. It’s now a widely followed fashion trend that turns your hair from blah to ooh la la.
Is this your first time joining the hair dye fun?
There are some things to consider before coloring. Consider the right color, type of hair dye, hair condition, and also basic questions like, “Should I wash my hair before I dye it?”
We searched high and low for answers. And now, we’re ready to tell you the difference dirty or clean hair would make to your hair dye result.
Can I Wash My Hair Before Dyeing It?
The best way to answer this age-old question is this:
Don’t dye dirty hair!
Back in the day, hair colorists advised their clients to come to the salon with dirty hair. But, it’s not because dirty hair can make the color process faster.
The real reason was coloring products used to be made with harsh chemicals that can be really damaging to the hair. And, the dirt on your hair can lessen the harmful effects.
Now, hair dyes are made with more gentle formulas. As a result, colorists recommend washing the hair to remove the grime before coloring, because the excess buildup might result in an uneven dye job.
The best way is to wait for at least 24 hours after washing before dyeing your hair.
How to Shampoo Your Hair Before Coloring
Following the answer to your worry, if you’re supposed to wash your hair before dyeing it, you should also know how to properly wash it.
First, use a gentle shampoo. We recommend sulfate-free products for gentle cleansing. It’s also best to avoid clarifying shampoos as they can be drying.
Here are our top picks for shampoos that will clean your hair in a gentle way:
- Caring, weightless formula
- Cleans and repairs damaged hair
- Has a sophisticated floral scent
- Softens and adds shine
- Contains argan oil that replenishes dry hair
- Perfect for all hair types
- Deep cleans and refreshes the scalp
- Leaves hair locks healthy and full of shine
- Color-safe, vegan, and paraben-free
Next, shampoo well if you’re a fan of using hair sprays, dry shampoo, or hair oils. Just make sure to be gentle when scrubbing your scalp.
Prepare Your Hair Before the Coloring Process
Hair dye products include damaging chemicals like hydrogen peroxide and ammonia. They can cause your hair to become frizzy and brittle.
That said, your hair should be in good condition before you color it to minimize the damage.
Here’s how you can prepare your locks:
- Avoid using heat-styling tools.
- Use a deep conditioner or treatment at least 3 days before dyeing your hair.
- Don’t wash your hair the same day as your coloring appointment.
Is It Better to Dye with Clean or Dirty Hair?
If you’re wondering if you can dye your hair without washing it, you need to consider a few factors.
The hair preparation factors are:
- Hair color
- Coloring technique
- Hair dye products
The Problem in Dyeing with Dirty Hair
Dirty Is Different from Oily
Hair can be dirty if it goes more than 3 days without washing. It has gathered a lot of hair product residue and environmental pollutants.
Whereas hair becomes oily after 1-2 days of no washing. It becomes coated with natural oil that gives it shine and smoothness.
Dirty Hair Can Confuse Your Hair Colorist
Light or blonde hair can appear darker when it’s dirty. So, when you have dirty hair during your salon consultation, you might not get your dream shade.
That’s because your colorist may not correctly evaluate your true hair color and they might end up using an incorrect color formulation.
On the other hand, clean hair shows your most accurate natural hair shade. This will help you find your best hair dye match.
That’s why it’s ideal that you wash your hair the night before your salon appointment.
Dirty Hair Can Cause Uneven Coloring
Too much dirt and product build-up can make it difficult for the hair dye to penetrate the hair cuticles. This can result in patchy hair color.
If you’re using a product with no ammonia or a low-volume developer, the dye may not break through the dirt stuck to your hair.
Squeaky Clean Hair When Dyeing Is a Big No
Cleaning your hair before coloring can ensure that there’s no dirt to prevent the hair dye from being absorbed into the hair shaft.
However, washing the hair right before dyeing can cause more damage as the hair and scalp are drier than usual.
Plus, freshly washed hair can make things difficult for your stylist when doing hair painting techniques such as balayage. This is because recently washed hair has more flyaways.
To achieve the perfect hair condition before coloring, professionals suggest that you skip shampooing at least 24 hours before the hair dye process.
What About Washing Prior to Bleaching?
If you’re planning to have an extremely light color like platinum blonde, you can skip 2 washes before going to the salon.
During that time, the body will produce sebum or natural oil that can nourish your hair and scalp.
It’s as if you’re preparing your mane for battle. The more oil there is to your hair, the more protection there is against breakage and irritation during the bleaching process.
The Power of Sebum
As we’ve explained, not shampooing for 1-2 days allows sebum to build up on your scalp. It moisturizes the hair and serves as an extra coating.
So, when the hair dye breaks down the cuticle, there is less damage.
Sebum can also help protect your scalp. There will be less tingling when using bleach and less staining for hair dye.
Aside from hair and scalp protection, the oil makes it easier to divide the hair into sections when coloring.
Oily Hair Strands Won’t Ruin the Hair Dye Process
Coloring can add pizzazz to your locks. However, it can also add damage. So, make sure to prepare your hair for its first hair dye experience.
Take note that neither dirty hair nor freshly-washed hair is good for coloring. Shampoo your hair 1-2 days before your color service to let natural oils work their way to your hair.
This will create a shield between your scalp and the harmful chemicals in hair dyes to prevent burning and itching. It also helps minimize hair damage.
Frequently Asked Questions
Is it better to have clean or dirty hair before coloring?
It’s better to go between clean and dirty if you’re going to color your hair. Too clean hair can be drying and too dirty can cause a sloppy hair color.
The best period of cleanliness is just when the natural oils have started to build up. That’s 24 hours after your last wash.
If my hair is greasy, do I need to wash my hair before I dye it?
We suggest having a little grease on your hair before coloring. But, take note of the word little. If your locks are too greasy after 4 days of no shampoo, dyeing it can be pretty challenging.
Can you use box dye on dirty hair?
Yes, you can use box dye on dirty hair. Most box dyes have high peroxide levels and ammonia that can go through the dirt on your hair.
However, we wouldn’t recommend that, as it’s still best to have only a little oil and not dirt on your hair before coloring it.
