If you have flat, thin, or ultra-fine hair, you already know the struggle: everything looks great when it’s wet… and then by the time it dries? Flat. Limp. Deflated. The frustrating truth—according to professional blowout stylists—is that most people with fine hair are simply using the wrong products.
“Volume is all about the right formulas,” explains the Blowout Professor in a recent viral video. “If your shampoo or styling products are too heavy, you can kiss volume goodbye.”
Out of all the volumizing products he breaks down, two stand out as true game-changers—ones stylists say can “save” fine hair for good. And the best part? They work for two different types of volume needs: all-over fullness and targeted lift at the crown.
Below, meet the two expert-approved products worth adding to your routine ASAP.

1. Moroccanoil Volumizing Mousse
Most mousse formulas create major height—but at a price. They leave crunchy residue, stiff texture, and serious product buildup. But if you want all-over fullness without the helmet-hair feel, stylists say Moroccanoil Volumizing Mousse is the exception.
“It’s the touchable option,” the Blowout Professor says. “Pretty good volume, not Texas-big or anything, and you can still run your fingers through it.”
This mousse deposits just enough product between each strand to give fine hair that airy, fuller look from roots to ends—without that heavy, gritty coating that forces you to wash your hair daily.
Who it’s perfect for:
- Fine hair that falls flat quickly
- Anyone who wants volume along the length of their hair (not just the crown)
- People who hate stiff, crunchy styling products
Apply a golf-ball-sized amount through damp hair, then blow-dry or use a blow-dry brush. Expect instantly thicker-looking hair that still feels soft and clean.

2. Kenra Root Lifting Spray
If your hair goes limp at the roots no matter what you do, this product may be your holy grail. Of every volumizer discussed in the video, the expert calls Kenra Root Lifting Spray his personal favorite—and his most recommended pick for almost everyone.
“Root lifter is the goldilocks option,” he explains. “It gives volume right where you want it—at the crown—without putting crunchy buildup all over your hair.” Unlike mousse, which creates volume everywhere, a root lifter focuses on the part of your hair that actually determines whether your style looks flat or full. When sprayed directly onto sections of the root and blow-dried upward, it creates long-lasting lift that keeps your hair from collapsing by midday.
Why pros swear by it:
- Lightweight and clean-feeling
- Doesn’t ruin your hair’s natural texture
- Gives lift that lasts hours—without looking stiff
- Ideal for fine, thin, or easily weighed-down roots
Just part your hair in mini sections around your crown, spray at the roots only, and blow-dry. It takes 30 seconds and delivers major payoff.
The Bottom Line: You Only Need One (Or Both)
If your hair is thin, fine, flat, or simply refuses to hold volume, these two products work for completely different—but equally crucial—reasons:
- Moroccanoil Volumizing Mousse = all-over fullness & thicker-looking lengths
- Kenra Root Lifting Spray = clean, long-lasting lift at the crown
Use one based on your hair’s needs—or combine both for maximum height, movement, and hold. According to the pros, these two formulas aren’t just styling products, they’re lifesavers for fine hair.
