It's described as a hair dye that is also conditioning, think of mixing your fashion semi permanent dyes with conditioner and this is pretty much a ready made version of that. When I first opened the pot I thought 'this isn't going to do a lot and have I wasted my cash' as it pretty much looked like one of my home made formulas using conditioner and Directions Lavender dye. But I thought I'd give it the benefit of the doubt before I used it - don't judge before you try!

Application was super easy - gloves are included which you may need for some of the darker brunette or red shades but I just grabbed a dollop with my bare hands and proceeded to run this through towel dried washed hair. It only recommends 3 minutes for the whole process and advises to leave on for no longer than 10 minutes. This is for the blonde shades and I have researched that the darker shades can actually be left for up to 30 minutes. I usually leave these sorts of treatments of for around 30 minutes but thought for my first try I'd follow the rules to see how effective it was. Three minutes later, I washed out the product and styled as usual and at first I didn't really think it did a lot but looking back at these pictures, I can see it really knocked out a few of the yellow tones I had lingering in my hair. I've always wanted to go for a light grey tone but I've never been brave enough yet but feel if you used this product a few times you may actually get a subtle grey result as you can see on my final close up picture. This was after just one application and following the 3 minute rule. 

As for how far the tub can go - it states one application can last up to 6 washes and each tub can give 5 applications dependant on hair length. I hardly even made a dent in tub and would say I probably used between 1/5 to 1/6 of the product. So at £6.99 this is a really cost effective toner and a lot easier to get your hands on considering you can purchase this from Superdrug. The product is also PPD free, bleach free and ammonia free. I can't recommend this product enough and suggest before and after photos just so you can see the differences. 

(Try not to judge the conditioning effects from my photos - my hair was in MAJOR need of a trim and I had one a few days after these photos were taken so apologies!)
