This straightening comb is meant to work in one swipe on any hair type

• We test the Tymo Ring Hair Straightener Comb that claims to work on all hair types and straighten in just one pass.

• We test the straightener on how well it straightens and how well it works for different hair types.
• We think the $50 straightener is worth it and works with straightening different hair types, and it even includes heat options for people with dyed or bleached hair.

Following is a transcript of the video.

Nico Reyes: You probably noticed that the only time I ever straighten my hair is when I'm doing a video about straightening hair, and today is one of those days. I'm going to be trying out the Tymo Ring Hair Straightener Comb. It's essentially a hair straightener in comb form that's supposed to straighten any type of hair easily. And because it's in the comb shape, it's supposed to kind of detangle as it's straightening.

I'm going to be testing this straightener out on how well it straightens and how well it straightens different hair types, so a couple of my friends will also be testing it out with me later.

The straightener does come with this little booklet of instructions, and there's a temperature-setting chart that shows you the appropriate temperature setting for your specific hair type. I think that I would be temperature setting No. 5, which is 410 degrees Fahrenheit, for thick, curly, and wavy hair. The product page says that this thing works in one stroke, which, I don't know if I believe that. Besides the heat protectant that I'm gonna be using, I have zero product in my hair right now. It's just my dry hair in its normal state.

For me, at least right now, it's definitely not a one-stroke situation. I do have to do a couple of passes, but this is still straightening pretty fast. I am gonna try and get a little bit closer to my roots, because they're still really curly and bumpy. I never, ever straighten my hair. People who straighten their hair all the time must be watching this like, what is she doing? Right now this is at 410, and I can easily touch it because these parts of the comb do not get hot, so people say that they can get really, really close to their scalp. So that's what I'm gonna try right now. It's doing pretty well. Let's try it this way. There's no bumps at all! I think it's gonna be a little bit harder once I start working on the back of my head just because it's not as easy for me to maneuver that, but this is pretty great.

OK. So, I'm almost done, but just, like, touching the top of my hair, this, like the crown of my head, is my problem area, and I can still feel some bumps back there. So I'm gonna turn around and try to work out some of the bumps on the back of my head. What was that video we did where I looked exactly like Jacob Black? [ding] I will say, I do like how my hair turned out. But before I give you my final thoughts, let's see how the Tymo comb worked out for my friends A. C. and Caroline.

A. C. Fowler: So, I think I have 4C hair, which is thick, curly hair. Black hair. Yeah, I have never, ever straightened my hair, ever before.

Caroline Aghajanian: I would say I have wavy hair, and then it gets puffier on the bottom. I just don't like that it's so flat up top. But it's fine.

Nico: And they have a chart on here that says, like, this is the right heat for you to use on your hair, and there is actually a section that's for bleached hair. So I feel like that's probably the one you're gonna have to use.

Caroline: Yeah. You know what? That's really good, because my biggest fear, I guess anyone that goes blond, is kind of -- like, your hair is so damaged, so if you iron it, sometimes it might break off. Like, even from here. And I'm like, I don't want my hair to break off from my scalp.

Nico: I think you're gonna be the same level as me. I was level five, which is, like, thick, curly hair, and it's 410 degrees.

A. C.: [gasps] Oh, I'm so nervous! [laughs]

Caroline: Wow! Oh, my gosh. [gasps] This is good!

A. C.: Oh, my gosh! [laughs] It's so straight. Holy moly. Let's just say, first little bit, that was very easy. It really did straighten it. My hair has never been straight before. I can, like, put it behind my ears. [laughs]

Caroline: Even at this low heat, it ironed it pretty well.

Nico: Is this faster than your normal straightener?

Caroline: Yeah, this is so fast. And, like, my normal straightener, it's a pretty good brand, but I still smell burning hair when I use it. Yeah. Even at a very low setting. And so, this one I don't. It's really good. So, I feel like I can get really close to my ears, because the outside blades aren't too hot. And so I can really get those hairs that don't really grow, or, like, the hairs that are super close to the scalp.

A. C.: So, yeah, overall I definitely think that this works for thick, curly hair. My hair type.

Nico: Clearly, my friends and I loved trying out the Tymo Hair Straightener Comb, and it actually straightened our hair really, really well, especially the roots, which was the big point of concern for us. Is it gonna get close enough to our roots where it doesn't burn us but still straightens? And it did. I think if you do have wavy or curly hair and want a method of straightening that isn't gonna take you all day, you'd really, really like this.
