What is a Keratin Treatment?

A keratin treatment is a chemical treatment that smooths and straightens your hair. It also eliminates frizz and adds shine to your tresses.

Often called a Brazillian Blowout, this procedure can have results that last as long as 6 months. While it can be done at home, it is best to go to a professional because they can create a concoction that will work best for your exact hair. 

Generally, the treatment is done on wet hair, where the product is brushed in, but some stylists apply it to dry hair. This likely depends on a few things: the stylist, the exact keratin formulation, and your hair type and damage level. The procedure ends by sealing the product into the follicle with a straight iron – heat is key!

This treatment isn’t for everyone, there are a couple of things to consider. While it’s all fine and dandy to have smooth, sleek, straight hair, there is a risk that formaldehyde is present in the concoction. Some keratin treatments contain this dangerous ingredient to help make your hair straighter. 

Formaldehyde is a carcinogen, meaning it can cause or encourage the growth of cancer cells. It is also extremely dangerous if inhaled. There are definitely formaldehyde-free keratin treatments, so don’t let this deter you if it is a look you truly desire!

Additionally, these treatments can cost upwards of a few hundred dollars, and some people can find the treatment difficult to maintain. One last thing you should be aware of is how long this process can take – bring a comfy pillow, you’ll be there for a few hours! 

This procedure is definitely not all negatives. The pros may outweigh the cons for most people; it can end up balancing out because you can pretty much be photo-ready in an instant, cutting out valuable get-ready time for both work and pleasure. Basically, do your research and decide if a keratin treatment is truly for you before committing!


If you have done a keratin treatment, or are considering it, then you definitely need to have a shampoo that will prolong the life of your treatment. Looking into what kind of shampoo you want to get is essential to the research process in deciding to do such a treatment. We’ve provided an excellent variety of the ultimate best shampoos for keratin-treated hair.

Your hair may be much more manageable, so make the best of it by grabbing one of these shampoos. This is an expensive, long treatment that you don’t want to waste away with your average-joe shampoo. Every day will be a great hair day with one of these shampoos that excellently complement any keratin-treated head.
