Sedu®

Birchbox Breakdown

Flat irons that expertly straighten hair without damage are few and far between. We know because we've tried them all. Our exhaustive testing has paid off: we've finally found our rock star. Not only does the Sedu® Revolution Flat Iron straighten our manes like a pro, but it also adds serious shine, thanks to tourmaline-infused ceramic plates. We also love that this flat iron heats up in 25 seconds flat, taking our locks from hot-mess to hotness in no time.

How it Works

The secret is in the tourmaline and ceramic plates, which are expertly polished to reduce static, eliminate frizz, and seal the hair follicle. As far as temperatures go, it starts at 170°F and goes all the way up to 450°F, which makes it appropriate for every hair type. This flat iron also includes a 9-foot swivel cord, allowing us to move (and dance) around freely as we straighten.

How to Use

Lightly spritz clean, towel-dried hair with a heat-protective mist and blow dry. Clip hair into 1- to 2-inch sections (leave one section out to start with) and turn your flat iron on to the appropriate heat setting for your hair type (the curlier the hair, the higher the heat). Allow the iron to warm up for 25 seconds and carefully clamp the iron down on the first section of hair, starting at the root. Gently pull the iron straight down the hair shaft in one smooth motion and go over the section a few times until straight. Repeat steps for the rest of the sections, seal in shine with some more styling mist, and whip your luscious hair back and forth accordingly.

I like it

I recently had to put my 8 year old straightner down. Randomly one morning it shorted it out. I was on the look for a new straightner ASAP and had a bad experience with one of the popular brands out there. So logged on to Birch box to see what they had. I had never heard of this brand, but read the reviews and also researched a little on my own. The minute it came in the mail I rushed upstairs to straightner my thick wavy that had been in a bun all day. It was magic. For most of my hair I only had to go through it one time and it was sleek and straight, with minimal gripping on my part. So far so good with this straightner.

Love it!!!

I love this flat iron. I previously had a T3, it broke and the T3 company is a nightmare to deal. I purchase the Sedu and it is so much better than the T3!

Worth the $$$

I have owned several different flat irons. This one is the best one I have ever used. It is the first one that I have owned with a temperature setting. I keep it set pretty low. It has not fried my hair like the others. My hair seems silkier than ever.

Very fast

Love the fact that this warms up so quickly. Use it every day and it leaves my hair feeling silky - not fried! Would buy again in a heartbeat.

LOVE

Love, love, love, this flat iron!!! it makes my hair so smooth and shiny. With my old straightener, I had to run it through my hair a couple times before it was how I wanted it; with this one, I don't do that. One pass through is usually all it needs. I have really long and thick hair, and straightening my hair doesn't take nearly as long as it used to!

Fabulous!

I have had this flat iron for years now- it is worth every single penny! It truly does add shine- I did a little comparison with my daughters' cheaper flat irons and it was amazing the difference in how smoothly this ran through the hair, how easy to handle, and adds shine shine shine to my hair. It also heats up in no time, and having variable temperature control gets it to the exact temperature that is right for your hair. It is truly fantastic, and has held up through me and two teenage girls, so I highly recommend it!

Totally worth it!

After my old cheap flat iron died after a year I decided to research the best one. Sedu was the winner and I am so happy I bought it! I knew I wouldn't be disappointed after all the research I did. Heats up quickly (I usually use the highest heat) and my hair is super shiny! I look forward to using this for many more years to come- I just need to pry it away from my mom and sister!

I like it, but not love it

It's a fine hair straightener, but I'm not sure I'm in love with it.
It doesn't stay hot very long, and makes me hand sore from closing it over and over again.

The mother of all flat irons

I just bought this at ULTA. But I wanted to let everyone know how amazing this flat iron is! I had no idea how bad my old flat iron had gotten. This leaves my hair so soft and smooth. Def better than a CHI or other comparable products.

Great at first but fades

I loved this flat iron at first, but after about 4 months it took a really long time for it to heat back up and straighten quickly.
