They are called Superdrug Colour Episode, and they’re currently sold for £2.99. I use the Dark Red Brown 4.5 and I must admit, I am in love.

The hair colour itself comes in a small bottle of mousse and you’re not required to mix it with anything, simply give it a quick shake, and you are ready to go! Beware though, this product is intended to be used on unwashed damp hair.

As with any hair colour, you will simply need to distribute evenly onto your hair and leave for the desired time. Another bonus is that the mousse is non-drip, so you don’t have to worry about the colour dripping onto the floor! The colour can stay on for up to 30 minutes, depending on how you want it to turn out. I tend to leave it on for 30 minutes, which results in a bright finished colour.

Now, expect the river of water to be bright and vivid, but that’s not an indication of the colour that your hair will be. You’re given a small sachet of conditioner with the dye, but I find it doesn’t tend to stretch very far, so I mix it in with my normal conditioner when I rinse the colour out. The dark brown red shade tends to require a lot of rinsing, but it’s worth it for such a rich colour.

The dyes are available in six shades: Burgundy Red 6.45, Dark Brown 4, Dark Red Brown 4.5, Honey Blonde 8.03, Rich Chestnut 5.4, and Rich Red 6.4.
1The more often you apply it, the longer the colour seems to last in the long run. The Dark Brown Red leaves my hair a lovely glossy red colour that doesn’t actually fade as quickly as you’d think it would.
Unlike ‘normal’ hair dyes that contain ammonia and harmful chemicals, this doesn’t damage your hair at all and just masks it in a rich colour that fades each time you wash it. I received loads of compliments on my new hair colour, which was strange as when I used to use permanent dyes on my hair, people hardly noticed!

I’d definitely recommend this range of hair colours as a cheap and easy way to update your look without breaking the bank, or your hair.

Do let me know how you get on with it when you give it a go.
