About Olia Unlike traditional haircolor, 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.

I luv'd the bottle shape made application simple. Great light sent no scalp burning. Amazing color so deep dark and shiny. My hair feels so soft in better condition then B4 I colored it. I won't buy anything else from now on. I hope it never is discontinued. Better then salon colors last so long haven't noticed fading yet. The creater of this line is a pure genius and I thank you!

Misleading product hair dye is not natural. It does have a chemicals in it and it’s not all oils I am allergic to hair dye. I always use hair dye that are made out of plants and oils and things like that and this one put me to hospital last night, which it tells you that it’s not a natural product.

I ordered and received the olia platinum black hair dye. I was so pleasantly surprised when I finally decided to apply it. It did not smell strong like ammonia like a lot of dyes do. It left my hair so soft and manageable after rinsing it out. My hair had such a glossy shine to it after rinsing the product and drying my hair. It seemed to last quite a long time in my hair as well like it didn't fade and rinse out quickly as some other brands do. I would definitely recommend this hair dye to anyone who has not tried the olia brand line yet you won't be disappointed.
Everyone knows black box dyes are a dreadful no no, THIS IS NOT ONE OF THOSE DYES. I dye really easy and no damage leaving my hair softer than before. I would say the

I really enjoyed using Garnier Olia 2.0 Soft Black. The application was easy and smooth, and I loved that it has no ammonia. The scent was mild and not overpowering. It covered my roots evenly and blended perfectly with the rest of my hair, giving a very natural and rich black color. After rinsing, there was no heavy residue left on my scalp or hair, and my hair felt clean, soft, and nourished. The color looked glossy and healthy, covered my grays completely, and didn’t dry out my hair. Even after several washes, the color stayed vibrant with no dullness.
Olia left my hair feeling soft and silky. The color was perfect and multidimensional leaving it very naturally looking. It faded naturally over time without looking streaky or damaged. Definitely will use again.

Q: Hello,
I am considering Olia Black 1.0 for my goth look. But, I am worried about sensitivity and damaging my hair. I've been cautioned: "DON'T DYE YOUR HAIR IT WILL GET DAMAGED" is this true? Also should I use this dye if I have not had a patch test.
A: Hi cu1kw, Yes Garnier Olia Hair Color 1.0 Black does contain PPD. It is an effective ingredient for creating long-lasting and vibrant color. Thanks for your interest in Garnier!

Q: I'm looking for tips on how to better cover the back of my head with dye and also how to keep my color longer?
A: Hi Dianacrst, Begin in one of the back sections and apply the color to the roots first. Since roots are the re-growth part of your hair, they need the longest processing time. Please try our Color Shield safe shampoo to lock in your hair color. If you need additional information please contact us @ Garnier 800-442-7643! Thanks for your interest in Garnier!

Q: Is this Simi permanent? If not do you have Simi permanent color dye in this product
Q: Why do you recommend not using Platinum Black on grey hair? My roots are about 70% gray. The rest of my hair to the ends are washed out (previously colored with Beautiful Collection, mahogany red brown, covered with Olia's soft black) brown and brass
A: Hello rayingainteasy ! Thank you for your interest in using 2.11 - Platinum Black . This shade is recommended for those with natural dark hair. It is also not for gray coverage, and yes, it will make the hair look much darker and your grays could take on a different tone other than dark gray. This is truly a shade for 100% natural dark hair in order to achieve the result.

Q: I have natural black hair will this color work good with my hair, and is the blue will show more or less.

A: Hi Tifcry! Thank you for your interest in Olia, 2.10-Black Sapphire. Your color result will depend on how your hair respond to the shade. Hair that is shoulder length or longer will require using more than one kit.
We recommend doing a strand test by mixing a small amount of the product. This test will give you some indication of the result you can expect.
A: Hi ketchup10! Thank you for your interest in using Olia, 1.0-Black. The blue/green color should be completely washed/faded out before using. The recommended natural haircolor for using this shade is; Medium Brown, Dark Brown, Darkest Brown and Black!
