    ammonia hair dye

    Garnier Olia Permanent Color 110 Superlight Natural Blonde is a real hit! I love that it’s completely ammonia-free – it makes the coloring process so much more pleasant. The creamy consistency makes the color super easy to apply, and the best part is that it doesn’t get messy! The scent is fresh and floral, which is so lovely compared to other hair dyes. The result was a light blonde shade that feels natural and soft, just what I was looking for. My roots are a bit dark ash and they disappeared! My hair didn’t feel damaged at all, but I still recommend following up with a good hair mask to maintain moisture and shine. The color also holds really well! I’m participating as a test pilot via Smartson and received a free test product 🤩

    Product Tester

    I got the color for free through Smartson when I acted as a product tester. The color was pretty good, plus for not having a strong smell. The consistency in the color was good and it was easy to apply. I could buy and use this again. 😊

    Really bad hair dye

    I am naturally red-haired (almost like the packaging shows) but I'm starting to get gray hairs that I haven't really accepted yet. Recently, I've been using Montibello (which by the way is super good!!), but due to finances, I wanted to try cheaper alternatives and never again! The roots turned super red and only certain highlights throughout the hair got the same color as the roots. The rest looked faded. My hair became patchy, in other words, and I colored according to the description. And no, I'm not fully gray yet. Tips etc. are declined because I did it right.

    Good product

    Natural color, easy to apply, pleasant neutral scent. Gray coverage is not very good. Did not stick to the skin, so all in all a really good product.

    Testing for Smartson

    I got to test Garnier Olio 8.0 Blonde which worked perfectly as an ugly grayish regrowth started to show. It was very easy to mix the product and apply it. I used a slightly wider brush that I already had at home. When I was done with all my hair - both regrowth, ends, and underneath - there was still a bit of color left in the bottle, so this product is perfect for long hair, I have 1 dm below my shoulders. The result was exactly what I had hoped for; nice fresh, and a beautiful natural blonde color!

    Very good

    Very good and gives a long-lasting result. You get a lot of product for the money, and I really like that a lot. I would definitely buy this product again and have actually just ordered the hair dye once more. I got the chance to test this product for free first as a tester at Smartson.

    Good price

    I love the copper color and I don't think it dries out my hair as much as other "box dye" can do. It says it should cover gray hair, and that's a minus point because I don't think it is sufficient for me.

    8.12 easy to apply

    I received the product for testing through Smartson. The product was really easy to apply and "soft". The scent was pleasant. The result was wonderfully soft and shiny hair.

    Professional results at home

    * product received for testing via Smartson. The color is easy to apply and doesn't smell as bad as many other hair dyes. I use color 3.0. The included conditioner smells really pleasant. The result is beautifully shiny, silky soft, and easily manageable hair.

    Golden light brown

    Good basic color, the scent is not strong. Easy to apply, the color matched my expectations realistically. I just wish for better color gloves.🙂 I received the product for testing from Smartson.

More shades

Dyeing your hair will never be the same again! Garnier Olia hair color is the first permanent hair color from Garnier formulated with oils. Free from Ammonia, this hair color is powered by oils to propel the color into the fibers of your hair instead. Olia is the new way to color your hair!

Optimal comfort for your scalp
Ammonia-free

Olia Hair Color with ODS-technology

The technology boosts the effect of the ingredients and removes the need to use ammonia and its harsh smell. The oil in Garnier Olia covers the hair and its surface. The high concentration of oil increases the level of alkaline substances in the hair fiber and enables the colorants to maximize the effect from within. Your hair looks healthier, shinier and feels softer. Keep in mind that shades with intense reflects (e.g., red shades) tend to provide less gray hair coverage than other shades.

In this kit:

1 cream developer tube 60 g
1 colorant tube 60 g
1 Silk & Shine after color treatment 54 ml
