Not great
Straightened but didn’t hold and also snapped a bit of my hair so returned it

It worked as expected. I recommend
Lary, 25 - 34
It’s ok
It’s okay you get what you pay for I’d be really unhappy if I paid full price

Straighteners
Straighteners are so lovely so smooth to use I really like them

Works well for a basic straightening
My experience with this straightener has been mixed. I have fairly curly and frizzy hair, and while the BaByliss Cosmos does a decent job of getting my hair pretty straight, it doesn’t leave it as sleek or smooth as I expected. It works well enough for a basic straightening, but my hair tends to frizz up again throughout the day, and I didn’t get that lasting sleek finish I was hoping for. I also feel like I have to go over sections more than with some other tools I’ve used. Overall, it’s okay for everyday use and worth a 3-star if you want straight hair, but if your focus is sleek, frizz-free results, it might not fully deliver.

Different but worked well
These looked really nice and different to other straighteners I have used. I like that they are small, easy to hold and use. In the box you do get a heat protective mat so can easily put it down. There are 3 heat settings and the straighteners are easy to use. I found that this worked well in my hair, it glider through easily, although felt needed thinner strands for it to be effective. I think the only thing I found strange is not being able to close them, the only thing can do is wrap the mat around it and velcro it to keep them closed. First time ever seen a pair like that. I would recommend them though, they work well and do what I need them to.

Good quality straighteners
I've been impressed with these straighteners. I have very long, thick, wavy hair and these glided through it with no problem. There are multiple heat settings which is good as it means you can protect your hair from heart damage by keeping it on a lower setting.

Great for 4C hair
I have 4C hair and The BaByliss Cosmos Sleek Hair Straightener exceeded my expectations. It heats up quickly, glides smoothly through the hair, and gives a sleek, shiny look without that burning smell. It’s Lightweight and really easy to use, and perfect for taking in my weekend bag. The design feels sturdy and the temperature settings gives great control for different hair types. Overall it’s and excellent straightener that gives salon-quality results at home.

Great results and visibly attractive
I love the colour, very feminine. They have a round tip and a good size power cord so they’re not restrictive. The heat mat is useful to protect my dressing table. I use the highest heat setting for quick results, I’m pleased with the glossy frizz free finish despite my colour damaged hair.

Babyliss Hair straighteners
Brilliant hair straighteners, my hair is curly and it straightens it amazing. It leaves your hair shiny and soft. You can turn the temperature up or down which I find is handy! The straighteners are stylish and I would highly recommend to any one who would like to have straight hair.
