If you're used to using professional hair tools, don't buy it.
In my opinion, it doesn't have enough power, yet it's hot. The quality is just not there, it feels cheap, it doesn't work half as good as my hairdryer. Great idea, but I didn't enjoyed using it.
It does the job, not as fast as I'd like it or I expect it to do. It has a funny smell, hotel hairdryers smell this way. I passionately hate those, and always travel with my own.
Yet, I must say that if you're usually fine with just basic hairdryers and aren't used to 200$+ hair styling tools you're most likely going to like it since it won't be a dramatic difference in the tool power like it is for me.
Use it once your hair the hair is about 80% dry and you'll get a pretty nice voluminous blowout.

Truly awful. This spray turned my healthy medium-blonde hair into a brassy, damaged mess after only two uses. I followed the instructions, applying liberally roots-to-tips, and then using a blow dryer. However, the result was dry hair that had lost its elasticity, and broke easily when brushing. Save your money and get a proper dye job at your salon - don't use this and have to pay as much to fix the damage it causes!

Waste of money. This shampoo, with 6 months of use, did not lighten my naturally medium-blonde hair at all, but left it dry and brittle instead. As a shampoo, it does its job, cleaning hair to an average sort of standard, but is not worth its price tag at all.

I used this conditioner for ages, desperately hoping that it might actually work. Spoiler: it did not. My natural hair is a medium blonde, and this conditioner had no effect on it, other than drying it out. The formula itself is average at best. It moisturises hair quite well, but I found with prolonged use (with the shampoo as well,) that it made my hair dry and brittle. Don't buy!

I've had a sample of 7 Day Volume for many months from a Walmart Beauty Box but was a afraid of using it after reading reviews. I have straight, fine, limp, thin hair. Highlighted and cut into a A-line bob. To get any semblance of body or volume, I apply root lifter and blow dry upside down, then carefully lifting hair in sections while using a round brush and teasing some on the top and sides after it's all dry. And then I have a hot flash and it all goes FLAT. Boo. Well, not anymore! Tried this product yesterday, I mean I have nothing to lose, so why not? Followed the directions on the bottle, in the shower after shampooing I starting off with a dime-size amount of the lotion, starting at the roots, making sure to work through to the ends. Added a bit more product (less than dime size) for the back. Waited a few minutes, rinsed. Styled as usual but this time my hair is awesome! It's shiny and looks like I actually have hair on my head like normal people :D I wash my hair daily, same body and volume today after washing. It's not dry or frizzy AT ALL, just super smooth, shiny but has body and volume. I'm really impressed with this product and wish I would have tried it sooner.
