About This Hair Dye Shade
Garnier Olia shade 5.03, "Medium Neutral Brown," is a natural brown shade specially designed to balance warm and cool tones in your hair for the most neutral color result. This shade also provides 100% gray coverage.

Is This Shade Right For Me?
Medium Neutral Brown hair dye is best for anyone with natural hair between light brown and darkest brown. If you want to explore other shades in the medium brown family, check out 5.0 Medium Brown and 5.3 Medium Golden Brown.

For anyone who currently has color treated hair, there are special considerations for the color result you can achieve. Because of this, we do not recommend shade 5.03 for hair that has been previously dyed shade 3.0 Darkest Brown or darker. For more help, use our Shade Selector Tool to find the shade for you!

About Olia
Unlike traditional hair dye, Olia uses a 60% oil blend with no ammonia natural flower oils to achieve brilliant, radiant color results. The oil powered technology propels colorants deep into the hair, giving you vivid, long-lasting color. Olia visibly improves and restores hair as the oils help to reverse roughness and dullness for more brilliant, long-lasting color. Olia-treated hair is hydrated, silky and up to 3X shinier than unwashed, uncolored hair.

The non-drip, velvety cream texture of Olia helps provide optimal comfort during application. Because Olia is ammonia-free, there is no harsh smell and it won't irritate your scalp. The hair dye kit includes everything you need: a developer applicator, a colorant tube, after-color conditioner, a set of gloves, and the instruction sheet. Follow the instruction sheet for the step-by-step process or watch our how-to videos below:

Olia 6 1/2.3 - Lightest Golden Brown

11 years ago
Love the color and the product. It is my first time that I use OLIA, my stylist recommended it. This is my second time I dyed my hair, my natural color is light brown with few grays, very fine and wavy in some areas. The first time I used Nutrisse Crème 63 Light Golden Brown. Loved the color of that product too, but I couldn't find it in any store. I heard it was discontinued. So after my stylist recommended I decided to try OLIA, my Mom helped me. I have to tell you guys that it has no odor, it is very soft like using conditioner and I did not have any allergy reaction. There is plenty of hair color in the bottle to use for long medium hair. I use to have that length in my hair, but in May 2014 I cut it short, for the first time. I love the results of the color and how soft my hair was after coloring. Another thing that make me decide to try it was because I suffer from allergies and asthma and products with strong odors like peroxide is not good for me. I wash my hair every day with Garnier Fructis Fortifying shampoo Color Shield and still have the color, now it is like growing and showing the roots but it's not much. I am going to wait for the end of August to dye my hair again, going to try a light color, looking for something in blonde color area that is not that light. I hope this review was helpful to other who want to try the dye color. Good luck!!

I used to use 6.1 which has been discontinued, and I saw on this web site to try 6.3 instead. I am in tears because my hair is now red instead of light brown.

Will leave your hair hydrated and smooth!

I used this on a small patch of hair to see how it was and after one use, it was so hydrated and smooth! The instructions were clear even in my dark hair I saw a difference just like the box says! I loved the shade!

Not impressed

a month ago
This box color did very little for my hair. I have naturally dark brown hair and it was lightened maybe one shade. It did nothing to cover my grays. Even now as it has grown out, you can barely see the line between my natural hair and the hair colored with the Olia. The process to preparing it was just like any other box dye and the application was just as easy. My hair texture was slightly less soft but nothing a good conditioner doesn’t fix. Overall, I wouldn’t go with this brand again because of how little it did for the grays.

This was great, the development was fast and the color looked good. It didn’t irritate my skin, or mess with my hair texture. I don’t feel like it lasted super long on my head but it had a good looking package.

Happy with my results

3 months ago
I was initially very skeptic. I didn't think it would retain long/be very apparent. My hair is thick/curly, naturally a dark brown/dark ash brown. Was told this color would fade into a natural looking chocolate which was what I wanted. The first couple of weeks, the change wasn't very apparent until after the first couple of washes. I stuck to washing every 5-7 days while also using Cantu Argan Leave-in conditioner which brightened it up/added moisture. I was happy with what I saw, and even more after the color retouch which I did about 5 weeks later. After that I was I was more than pleased! Definitely got the chocolate color I was going for. Its been about 3 months since the initial dye and its faded very nicely into chocolate/brown highlights. Was thinking of trying the 5.15 next. Overall, had no irritation or visible damage. Hair fallout has been average but the texture and shine overall was great! Will definitely use this brand again.

Yes, I recommend this product.

Does the job!

I actually use this box on my mom and it turned out fantastic. Although nothing lasts that long on her she enjoyed the freshen up. It was easy to use. It wasn’t irritating and when applying properly you’re not staining everything I’m sure it’s a great value however she has a specific color that she always goes to so she won’t be buying it again.

Q: The medium brown 5.0 was a little too dark. Which shade do you recommend that would be just a tiny bit lighter?

  • A: Hello, Thanks for reaching out! We suggest using a clarifying shampoo to fade your hair color. Fading is a gradual process and may require multiple sessions to achieve the desired shade. Once the color has faded we suggest trying Olia 6.0 Light Brown in a touch up application. We thank you for your interest in Garnier!

  • A: Hi random90210, Thanks for reaching out! Wait a minimum of 24 hours after your color process for best results. When applying hair color its best to wait until the last 5-10 minutes of processing time to touch up the ends. This prevents over processing. Thanks for your interest in Garnier!
