GETTING AN ULTRA MODERN STRAIGHT LOOK – Make sure to watch the how-to video at . Then start by using Brilliance New York  heat protectant spray.

  1. Brush your hair thoroughly making sure there are no knots or tangles. Starting at your ear line, section you hair using your fingers or a comb and clip the top section up.
  2. Starting as close to your roots as safely possible, place the combed 2 inch / 5 cm section of hair in the center of the two plates of your Brilliance New York Diamond Iron, close the styler with a nice grip.
  3. Slowly and carefully pull the styler away from your roots, allowing your hair to glide through the Diamond plates.
  4. Repeat the above steps for all of your hair, section by section, until you are finished.


Tips from the salon:

  1. Using less hair is better and sliding the iron down slowly is recommended.
  2. For best results use Brilliance New York Easy comb and go slowly.
  3. Finish up with Brilliance New York hair serum to give your hair extra shine and brilliance.


CURLS – Make sure to watch the how-to video

  1. Insert a 2 inch / 5 cm section of your hair between the plates, gently squeeze the handles together and turn your Diamond Iron upwards toward your head.
  2. After completing a FULL turn, slowly slide your styler all the way down. The hair will bounce into a curl once out of the plates.


Tips from the salon:

  1. To avoid a fish tail- Remember to always keep the hair in the center of the plates and don’t go too fast when you get to the tip of your hair.
  2. The slower you go the tighter the curl, the faster you go the looser the curl will be.



  1. Insert a 2 inch / 5 cm section of hair between the plates, then gently squeeze the handles together and glide slowly. Once you get half way down your hair (without stopping) slightly bend your wrist outwards and continue to slide all the way to the end.
  2. To flip the hair under, flip wrist inward to curl under.


WAVES / BODY & VOLUME – Make sure to watch the how-to video

  1. Follow instructions for curls and just use a bigger section of hair and go faster while gliding the styler.
  2. For body and volume, start as close as safely possible to your roots, and instead of gliding the styler down, push it UP and away in the shape of a rainbow, lifting your roots and giving your hair more body at the root.

    Its ok it doesn’t straightened course hair as I expected. Anyway I can work with it.

    • We are sorry your flat iron did not live up to your expectations. Our is a great way product to use in conjunction with thick, course hair. It keeps your hair healthy and gives you that gloss effect you see in shampoo commercials. Let us know if we can help you in anyway. You can contact customer service at if you have any questions.

    I have insane curly/wavy Puerto Rican hair that likes to frizz and behave however it wants to regardless of what I try. Over the years I’ve used tons of mousses and creams to try and keep my hair in check, as well as my fair share of hair straighteners and sprays – but always my hair stays a hot frizzy mess, and, when straightened, is never that beautiful silky shine you dream about.

    This is the first straightener EVER to not dry my hair out AND leave it perfect and shiny and gorgeous WITH NO FRIZZ. THIS IS A MIRACLE. I am not an easy sell, and trust me – being a student this wasn’t an easy purchase because it’s quite pricey for wallet’s current state: but this is an investment! And an investment well spent. I will definitely be back for more Brilliance New York at some point. Well done, people who designed this. Well done, indeed.

    • Thank you for the glowing review! We are glad you like your product. It’s Brilliance New York’s goal to only produce products with the highest quality materials so that you can style quickly without damaging your hair. We think the results and the time you save is worth every penny.

    Does this straightener have a self timer just in case if I forgot to turn it off? My dad cut the cord on mine and said I left it on :((( I would think that such an expensive straightener would have a function like so.

    Is this the flat iron that uses steam? That I can straight wet hair without having to blow dry first?

    • Hi Suzy, unfortunately, no. This flat iron can only be used on dry hair. We do not carry a wet to dry model primarily because applying direct heat to wet hair is not recommended. We recommend blow drying the hair from a distance and then using a flat iron or a curler to style it.

    i just bought this at the mall. the salesman said this works with steam and you can straighten wet hair too..

    • Hi Heather and thanks for reaching out!
      We do not recommend applying any heat to wet hair. When wet, hair is most fragile and heat can compromise the hairs’ natural health and vigor.
      The 100% ceramic flat iron does emit steam once in contact with your hair due to cutting edge technology incorporating a ceramic heating element and diamond infused plates. This steam is healthy and helps add shine and softness when you style your hair however, once again, we do not recommend using this or any other flat iron for that matter on wet hair.

      Hope this answers your question! 🙂

    Went to a mall and purchased this flat iron. The girl lied about a lot of the information. She claimed to be a hairdresser which I am myself …it was obvious she isn’t educated in the hair..just wanted to sell the product. You are never ever suppose to put any kind of heat on wet hair whether it’s wet or damp. Otherwise yes it makes the hair very shiny and healthy looking.

    • Hi, Kamarinn. We’re pleased to know that you’re happy with your BNY Diamond Flat Iron! This product is not intended to be used on wet hair, nor do we recommend ever using any flat iron on wet hair. We apologize that you were misinformed. However please note, mall and kiosk operators are independent resellers and not Brilliance New York employees.
