Usually after I colour my hair (which is pretty frequently) my hair feels pretty fried no matter how much I condition it. After using Olia, my hair actually feels in BETTER condition after I coloured it, than it did before. I purchased it in Brown 5.0 to cover a dark purple I had in my hair before. it did a really good job of taking my hair to a glossy brown shade, and covering the purple which other dyes haven't.
As for application, it can be a leeettle bit tricky to apply seeing as it is oil based. This means it isn't as easy to "spread" throughout the hair and you really have to make sure you cover all the strands. Because of this, the application took me about 25-30 minutes. I've heard how a lot of people hate the bottle shape, but I really don't mind. The smell is SO much better than any of the other dye's I've used. The fact that is has no ammonia is really great, because for someone who colours their hair as much as I do, it's nice to try and minimize the chemicals. I'm happy with the colour, incredibly happy with the condition of my hair, and indifferent about the application. Because of the good colour quality, and the amazing condition of my hair, I would definitely buy this hair colour before any other box dye.
Beautiful product, it made my hair appear to be the colour it said it would while making it feel nice and smell nice with the conditioner instead of hair dye. I like that this does not contain ammonia so it doesn’t smell too bad or sting my scalp. It doesn’t drip whilst it’s on either so it’s not too messy.
