Flat Irons for Brazilian Keratin Treatments

Using the right flat iron is vital for getting the desired results after your keratin treatment. The flat ironing stage of the treatment requires a hair straightener with ultra-high heat output. High heat is necessary to seal the hair cuticles and to ensure superior shine and silky smooth finish.

When you use a hot hair iron to seal a keratin treatment onto the hair shaft it would be best that your flat iron is constructed with titanium plates. Also, make sure to have an iron that heats up to 450°F with easy to read display. An adjustable heat setting is a vital feature that enables you to set the temperature that is appropriate for your hair type.

Why are Titanium Plates Important?

Titanium has the ability to reach a very high temperature in just a few seconds. The metal is inert and will not interact with any hair product. Titanium also retains heat better than ceramics and provides even heat distribution. The titanium plates will retain consistent heat levels when you start the flat-ironing stage of the treatment. This will result in the perfect finish and will give your hair an unbeatable shine.

To activate the keratin in the straightening product, the flat iron should be capable of reaching 450°F. When you are sealing the treatment into your hair it is important to use a flat iron that can maintain the temperature without heat fluctuation. Later, you can use the same flat iron to style your keratin straightened hair. However, for styling purposes, you don’t need to go over 400°F degrees.

Now, you are ready to make a choice among different models of titanium hair straighteners and find the one that suits the purpose of doing keratin treatment.

The following flat irons are worth considering if you are planning to apply the treatment in the comfort of your home.

7 thoughts on “Flat Irons for Brazilian Keratin Treatments”

  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.
