    After only using his a few times I am placing an order for 2 more bottles!
    I have short, flat, lifeless hair which I like to style funky, choppy and a bit of what I like to call 'organised messy' and this spray has given my hair a new lease of life, it even feels thicker and so much easier to style.

    I will be using this for a long time.
    Amazing product!!!
