"I’m a massive, massive mousse fan. I start almost every hairstyle with mousse," says Josh. Why? "The great thing about it is, it's a lightweight body-building styler that you can layer upon." By this Josh means you can use it on damp hair in the morning pre-blow-dry and then use it on dry hair in the evening before refreshing your style.
"A lot of products that build body, once you use it once, you can’t layer it again and again," he says. But "mousse is so lightweight and it absorbs into the hair and really allows it to be pliable and versatile and gives you multiple looks."
As for a specific one, he doesn't say, but he will say that he's a "big fan of alcohol [in mousse]. That really gives it the texture, the fullness and versatility."
