"The second thing that I would say is when you go to bed, go to sleep with a very, very loose top knot," he says. "I would probably use a scrunchie."

Tip 4: Add some volume with dry shampoo

Abergel recommends opting for a dry shampoo on your day 2 hair to restore some of its volume. When choosing a dry shampoo, he prefers "clean" straightforward formulas like Virtue's Refresh Dry Shampoo, which soaks up oils and adds an instant lift to the strands without adding a texturizing effect.

"You're going to lift the hair and I would spray it in sections very loosely," he explained as he demonstrated the technique on a mannequin. "Now, we've left it, let's say for like a minute or two, then you're going to take your fingertips and that's when you start running your fingers through your hair and that's how all of the oils are going to get soaked up into it. The secret is you have to wait at least a minute before doing that. So, that's what I would say for day 2, 3 and maybe even like 4 on the dry shampoo situation."
