Step 1 Use Heat Protectant
Whenever straightened hair with volume is the goal, you first need to start with a heat protectant and thought is not going to add volume to your hair; it does play an important role.
Heat protectants will keep your hair from becoming brittle and dry, which contributes to greater volume later on in the process.

Step 2 Pull it into a Bun
For this next step, you’ll want to pull the top half of your hair, into a bun.
You’re going to need to straighten your hair in three different layers, at least, but if you have very thick hair, you’ll probably have to separate it into, even more, thinner sections.

Step 3 Start Small: Voloom Petite 1-Inch Professional Volumizing Hair Iron
The next thing you’ll want to do is start with a small section of hair near your hairline. Taking a 1 to 2-inch section, clamp your iron as close as you can without burning your scalp.
If you are working with extremely fine hair you need a special type of straightener. We recommend Voloom Petite 1-Inch Professional Volumizing Hair Iron.
The VOLOOM iron is designed specifically to give you lasting hair volume, so you can extend the amount of time between shampoos and colorings. With fewer colorings and shampoos, your hair will start to become even healthier.
Ceramic plates paired with a patented checkerboard design work the under layers of your hair to create a hidden volumizing structure or “volume pockets” that lift the top layers up and away from the scalp, creating a fuller, more voluminous look.
The VOLOOM iron is a hair volumizer that eliminates the need for costly blowouts and hair stylings products such as volumizing sprays, gels, and mousses that weigh hair down.
How to use Voloom Petite 1-Inch Professional Volumizing Hair Iron:
- Part your hair normally and then section off the top layer that you would like to stay smooth. Clip this layer to the other side.
- Section off another layer, underneath the upper smooth layer, hold the under-layer straight up from the head, and clamp VOLOOM for one to two seconds near the scalp and release.
- Repeat the clamp and release technique two or three times, moving down the hair shaft. Repeat steps 1 and 2 on the other side.

Step 4 Pull hair upward
Instead of pulling the hair back and straight as you might be accustomed to with straightening, pull it upward and away from your scalp.
Once the straightener is halfway through the strand, go ahead, and pull the iron away from your head. Going upward, instead of straight back or down will create volume.

Step 5 Continue straightening
Continue straightening and finish the rest of the layers similarly to the first.
At this point, you can start teasing your hair but make sure you use a flexible hairspray to ensure that you can style the hair while allowing it to move around a bit, this too will help to add more volume.
Remember to work in small sections. The thicker your hair is, the more work it is going to be, but it’s definitely worth it in the end.

Step 6 Finish
Finish the job by running your fingers through the hair, beginning at the roots to give it some lift.
