The second number is the reflect which can be Natural (.0), Warm (.3, .4, .5, .6) or Cool (.1, .2). For example, 1.0 is a Natural Deep Black and 3.23 is a soft black with chocolate undertones.

    doesn’t last long

    a year ago
    lovely colour at first after washing out and for the first couple days before i washed it again. i dyed it on the 5th January 2025 and have washed it every 5 days and the colour has already started to wash out. i’ve done everything i can to try and make it last (not washing as often, washing at right temperature etc) but it just keeps washing out by a lot. it also made my hair extremely greasy when first washing out.

    No, I do not recommend this product.

    Perfect colour for natural Asian black hair

    a year ago
    Did exactly what it needed to do. I dyed all of my hair hazel brown 2 years ago and have since let my natural Asian black hair grow out, all the way until mid my ears. It was time to match my dyed hair to my natural black hair. I was researching and checking video reviews between different Olia colours and ended up with 3.0, not too black but also not too brown. Literally no one can tell my dyed hair from my natural hair! And I didn't even go over my natural hair with this dye, I literally only dyed my coloured hair (used 2 boxes for this, imagine hair from mid ear all the way to mid bum). Did not end up using the conditioner, used my own instead :)

    Yes, I recommend this product.
