That it's so windy this week can go two ways. My hair is either full of volume because it's been blown in every direction or it's incredibly flat, making the hairstyle look very sad. In the latter case, I need to find a solution. Not only after a bike ride do I want a lot of volume, but I actually want that effect all the time. So bring on the product that creates volume in the hair.

What does it promise?

That little bike ride every morning always flattens my hair again. I wish it were different, but no, I just have very fine and lifeless hair.. This spray gives extra volume. You apply it to the roots, making the hair a bit stiffer and giving it instant volume. The nice thing is that it's enriched with argan oil, which actually nourishes the scalp. This makes the hair thicker and keeps the volume for a long time.

The test

Josselin: “In the morning, I don't spend a lot of time on my hair, maybe that's why it often looks so flat, but what I always do is blow-dry. That at least gives a bit of volume and then it looks somewhat styled again. After blow-drying, I always use a dust powder to boost the volume a bit more. It does make it a bit stiffer, but it often stays styled. This root boost works pretty much the same as the dust powder, but you have to use it before blow-drying. You can't just spray it on during the day because then you end up with quite a gray head. So I applied it to wet hair before blow-drying, then got to work and to be honest, there is definitely volume. The nice thing is that the hair becomes a bit stiffer, because if it starts to fall flat during the day, you can just run your hands through it and it looks as good as new. Oh, and after the bike ride, it works really well. Test passed.”
