We Tested a Cordless Hot Brush That Straightens Hair on the Go

Following is a transcript of the video.

Nico Reyes: I don't straighten my own hair ever, mainly because I have a lot of hair and it's exhausting, but I'm also always worried about heat damage. Then I saw this, the Dafni Allure Portable Hair Straightening Brush, which supposedly straightens any hair type without damage. Plus it's super small and wireless, which is great because I'm going to need all of my arm strength to straighten all of this.

I'm also going to have my friend Sydney, who has a more wavy hair type, come in and try the brush too.

I'm going to start off by sectioning my hair into smaller pieces and spraying on some heat protectant. We're going to work from the bottom up. I think that's how people do it. The brush is fully charged. It says that one full charge can straighten three heads. Their words, not mine. And it only has one temperature, 365 degrees. It says that that's the optimal temperature to prevent heat damage. My concern is that that is not hot enough to straighten my curls, but let's see.

It's straightening, but not in a good way. Like, look how bumpy it is. I can already tell, even though it says it's for all hair types, it's not accounting for time spent. So if you have hair even curlier than mine, coily hair, you're going to be doing this probably forever, 'cause it's already taking me forever to do one piece.

It's got these four little lights on the side of the brush that tell you how charged it is. I'm already down to three lights, and I just started. So how I'm going to get through my whole head, let alone two other people's heads, with one charge, it's just not true. I don't think that's true.

I feel like my roots still feel a little puffy. It's just really hard to get in there. This low, low heat is killing me. Like, I get it. We want to stop heat damage. She needs to be stopped. But it's also like, if I'm doing 40-plus passes through my one piece of hair, how much heat damage am I actually avoiding?

Ah! We're down to one charging dot. I'm pissed off. Three heads, they said. Three heads you can straighten in one charge. We've literally only been filming the straightening portion for 15 minutes, and it's already almost dying. So I'm really annoyed. I thought this was going to last me my whole head! Maybe by "three heads" they mean people with short bobs and pretty straight hair.

[brush beeps] And she's dead. So now I have to wait another 30 or so minutes for it to be charged again to finish. I'm frustrated. It's just taking so long, and I want it to be over. We're going to take a brief intermission, and I'll be right back when she decides to wake up.

The same way it's super hard to straighten my roots, it's also hard to get my ends completely straight. No matter how slow or fast I'm going, they still look really frizzy and just all over the place. [brush beeps] And she's dead. And so am I.

Sydney Bradley: I think it is going to straighten my hair, but not have it be super sleek. It's nice 'cause it detangles my hair at the same time. One thing I hate is holding the brush while I have a flat iron in my hand. But it's a good temperature, it doesn't feel too hot. I don't really feel like it's damaging my hair.

So, it's a little harder to get straight to the root of my hair up here. It's straightening, but it still has a lot of volume right here, and it's a little bit difficult to maneuver. This is much more what my hair looks like with a hair-straightening attachment on a blow-dryer. It's still kind of fluffy and a little bit wavy, but it's not as pin-straight or silky as I'd want it to be, or that it would be if I used my regular flat iron.

I think it is easy to use, just because it feels like I'm brushing my hair and it's just a hot brush that straightens, but it doesn't do, I guess, what I want out of a straightener.

Nico: I think this speaks for itself. I'm not going to sit here and call this a success. I think we can all very clearly see that the straightening aspect of this straightening brush doesn't really work out for me with my curly hair. And I don't see how it's going to work for anyone with even curlier or coily hair. It's just not hot enough. I feel like the claim about minimizing the heat damage doesn't really apply when you have to go over the same piece of hair 20 times. And this is what it looks like when I did that! It still looks bad!
