The decision to have a Brazilian keratin hair straightening treatment is not something you should take lightly. The process takes a while to perform, it is not inexpensive, and the results last a very long time.

In other words, it’s not something you should do on the spur of the moment. There are some important consequences to consider.

How Long It Takes

Depending on the condition of your hair and the skill of the hair stylist, applying your keratin hair straightening treatment could take anywhere from three to six hours. And once the process is started, it can’t be stopped without potentially damaging your hair.

But the time you invest will be well worth it. Keratin treatments can relax about 80% to 90% of your hair  and will remove nearly all of the frizz (although some of your natural wave might remain). Plus, because it is heat activated, once you get your treatment, your styling time later will be substantially shorter.

How You Will Look

When you get a Brazilian keratin hair straightening treatment, it’s usually a good idea to get a light trim right afterwards. This removes any of the ends of your hair that may become damaged during the process.

Obviously, you can have as much or as little of your hair trimmed as you like. But getting at least the ends cut off will help improve the look of your keratin treatment and leave you looking brand new and fabulous.

How Long It Lasts

You can expect your post-treatment hair to remain straight and lush for at least two months and up to six months, depending on the natural condition of your hair and how well you maintain it afterwards.

Over time, however, the keratin hair treatment will wash out and your hair will go back to its original texture. So while it is long lasting, it’s not permanent.
