7.0 - Dark Blonde

Product Information

Unlike traditional hair dye, Garnier Olia oil-powered permanent hair color (shade 7.0 Dark Blonde) uses a 60% blend of natural flower oils to deliver vivid, long-lasting results with up to 3x shine vs uncolored, untreated hair. The oil-powered technology creates a velvety cream texture for optimal comfort during application. It infuses colorants deep into the hair cortex, giving you vivid, long-lasting color. Formulated for every hair type and texture, Olia visibly improves and restores for hair that’s silky and up to 3x shinier than unwashed, uncolored hair.

About This Hair Dye Shade
Garnier Olia 7.0 Dark Blonde is a neutral, pure dark blonde shade (no added warm/cool reflects) that lets your natural tones show through while providing 100% gray coverage.

Is This Shade Right For Me?
Level 7 dark blonde hair color is best for natural hair between medium blonde and medium brown. Want a fashion-forward rose tone? See Olia Dark Rose Quartz. For a lighter shade that still reflects naturally, check out Olia 8.0 Medium Blonde.

For those who currently have color treated hair, there are special considerations for the color result you can achieve. Because of this, we do not recommend shade 7.0 for hair that has been previously colored shade 5.0 Medium Brown or darker. For more help, use our Shade Selector Tool to find the shade for you!

Frequently Asked Questions

How Long Does Olia 7.0 Dark Blonde Hair Color Last?
Olia shade 7.0 is an ammonia-free permanent blonde hair dye that typically lasts 4–6 weeks, depending on hair porosity and how often you wash your hair. As the color naturally grows out, Olia’s 60% oil-powered formula helps maintain softness and shine.
Can I Use Olia 7.0 Dark Blonde Hair Color on Textured Hair?
Olia is formulated for excellent results on all hair types and textures, including waves, curls, and coils. The oil-rich cream developer helps nourish textured hair while evenly depositing pigments.
Does Olia 7.0 Dark Blonde Hair Color Fade?
Olia contains dark blonde hair color pigments developed to resist fading. However, permanent blonde hair dye shades may become slightly softer with time. You can delay any fading and keep the tone bright by washing with a sulfate-free shampoo and conditioner, as well as avoiding exposure to heat (hot water, styling tools, etc.).
Does Olia 7.0 Dark Blonde Hair Color Work on Black Hair?
Since this Olia shade is a Level 7 dark blonde hair color, it will not lift black hair to the dark blonde results shown without lightening. If you want a true 7.0 color on black hair, we recommend lightening your hair beforehand.
How Can I Maintain My Olia 7.0 Dark Blonde Hair Color?
To keep your dark blonde hair color looking fresh and vibrant, use color-safe, sulfate-free hair care products like Color Shield shampoo and conditioner, and always rinse with cool water to seal in the pigment. Protect your color and preserve tone by staying away from UV rays and hot tools (including the blow dryer).
Can I Use Olia 7.0 Permanent Blonde Hair Dye on Dyed or Bleached Hair?
Olia 7.0 Dark Blonde hair color can be applied to hair that has already been colored or lightened, but porous areas may absorb more pigment, thereby making the color look slightly different. It’s best to perform a strand test before a full application to see how warm or deep this Olia shade will be.
Will Olia 7.0 Dark Blonde Hair Color Appear Redder on Highly Porous Warm or Lightened Hair?
Will Olia 7.0 Dark Blonde Hair Color Appear Redder on Highly Porous Warm or Lightened Hair? Hair that is very porous, warm or pre-lightened may reveal gold or reddish undertones when using this dark blonde hair color. If you are aiming for a neutral dark blonde, this red-pull effect may be avoided by using a pre-toner or a hair filler.
Does Olia 7.0 Permanent Blonde Hair Dye Provide 100% Gray Coverage?
Even though Olia is an ammonia-free hair color range, it is formulated for 100% gray coverage. We recommend leaving the developer on for the full processing time to color stubborn grays.
How Long Should I Process Olia 7.0 Dark Blonde Hair Color on Virgin Hair Compared to a Root Retouch?
To achieve even lift and saturation on virgin hair, leave on this Olia dark blonde hair color shade for the full recommended processing time. For a root touchup, apply the dye to the regrowth first, and then refresh the lengths in the final minutes (if needed).
When Doing a Root Touchup, Should I Apply Olia 7.0 Dark Blonde Hair Color to the Ends or Only the Regrowth?
Root retouches only target the regrowth. Pull the color to the ends briefly if you want to refresh the tone. Over time, repeated coloring on a full head of hair can deepen the color of the ends.
Do I Need to Do a Strand Test and Allergy Test Before Applying Olia 7.0 Dark Blonde Hair Color?
Garnier recommends performing both a strand test and an allergy test before each use of this permanent blonde hair dye. These tests are especially important when applying it to lightened or porous hair. A patch test will ensure the application is safe and irritation-free when using this ammonia-free formula.
How Many Boxes of Olia 7.0 Dark Blonde Hair Color Do I Need for Long and/or Very Thick Hair?
As a general guideline, plan on using one box for short to medium hair, and two boxes for long, thick, or dense textures. The key to even blonde color is to achieve full saturation.
Is Olia 7.0 Dark Blonde Hair Color Suitable for Relaxed, Permed, Keratin-Treated, or Henna-Treated Hair?
Chemically treated hair tends to process faster and absorb more deeply, whereas color results on henna-treated hair may be unpredictable. It is best to wait before dying if relaxers, perms or keratin treatments have been applied. Always perform a strand test before using this dark blonde hair color.
Will Olia 7.0 Dark Blonde Hair Color Dry Out My Hair? What Conditioners or Masks Should I Use After Coloring?
Ammonia-free Olia contains a 60% oil blend that leaves hair softer and shinier after coloring. For after-color care, use moisture-rich conditioners and/or weekly masks to maintain softness, depending on your hair type and texture.
How Soon After Using Olia 7.0 Dark Blonde Hair Color Can I Heat Style, Swim or Spend Time in the Sun?
After applying this permanent blonde hair dye, we recommend waiting 48–72 hours before heat styling or swimming to allow the color to fully cure. Wear UV protection (hat or scarf) and wash/style with color-care products for long-term vibrancy.
Does Hard Water Affect How Long Olia 7.0 Dark Blonde Hair Color Lasts?
Hard water with elevated calcium levels tends to dull blonde tones more quickly, especially on porous or previously lightened hair. To maintain clarity and shine, occasionally use a clarifying or chelating shampoo followed by conditioner.
