Flat Irons for Brazilian Keratin Treatments

Choosing the right flat iron is essential for getting the best results from your keratin treatment. The flat ironing part requires high heat. The high heat of the flat iron is necessary for sealing the keratin in your hair and to ensure superior shine and a silky smooth look.

What to Look for?

When you use a hot hair iron to seal a keratin treatment onto the hair shaft your flat iron must be constructed with titanium plates. Also, make sure to have an iron that heats up to 450°F with easy to read display and controls. Being able to adjust flat iron temperatures is also important.

Why are Titanium Plates Important?

Titanium has the ability to reach up to the set high temperature in just a few seconds. It is inert and will not interact with any styling products. Titanium also retains heat better than ceramics and offers even heat distribution. The titanium plates will retain the consistent heat levels, once you start straightening. This will result in the perfect finish and will give your hair unbeatable shine.

Up to 450 Degree Heating Capability

To activate the keratin in the treatment, the flat iron should be capable of reaching 450 °F. When doing the treatment, it is important to have a flat iron that can maintain the temperature you set without heat fluctuation. You can use the same flat iron after the keratin treatment application. You don’t have to go over 400 degrees when styling your hair.

So, which flat iron should you use during the keratin treatment? The following flat irons are good choices to be used during the keratin treatment application and after.

  1. This flat iron can go up 455 degrees, which is enough to ensure that the treatment is sealed into your hair. Another feature – Advanced Ceramics™ heating system helps maintain constant high heat during use. You definitely can use this flat iron for doing a keratin treatment.
    However, for best results, I would suggest a flat iron with titanium plates because titanium plates are best for maintaining consistent high heat, needed for an even sealing of the straightening product.

  2. Using a flat iron with titanium plates for smoothing treatments would provide you with better results.
    Consult your stylist before doing any chemical treatment.

  3. Yes, if you turn off the steam button. To get the best results your flat iron should have titanium plates (to provide continuous and stable temperatures) and a temperature range up to 450 F.
