Greying hair

Dry shampoo:

I had a go at making hair appear grey and dry, as I would like to use this effect for my Dorian Grey interpretation. I used dry shampoo, splitting the hair into layers and taking thin sections, then spraying the hair with the shampoo. I had to use quite a lot to get a strong colour. I then combed through any harsh sections to even the colour out, and worked through the whole section of hair. I thought this technique worked quite well, however I was spraying the product sideways rather than up and down the length of the hair which meant it looked a little stripy in places. If I were to use this technique again I would be more careful about where the product sits in the hair. Also, because dry shampoo is a powdery product, in places were the product was heavier it was visibly flaky and powdery, and so looked less convincing. I also thought it looked a little too white. 

Kryolan Aqua-Colour:

At first, I used the white Aqua-colour on a spoolie brush and combed it through the hair. However it had  slightly bluish tint - so I mixed in a little black to make it more of a grey colour. It still looked a little blue, so I added a tiny bit of yellow to contrast the blue tones. This mix of colours meant there was variation in tones and shades in the hair, making it look more natural. It also looked less powdery than the dry shampoo method, and did not move around or fall out when I touched, brushed or moved the hair. It also added a dry texture, which is perfect for my design as it includes damaged, aged hair. Therefore, I think the Aqua-Colour technique is best for my design. I just need to make sure to use a variation of shades and use a little yellow to tone out the blue tints.
