Keratin Straightening: Pros and Cons

These days it seems like we can’t stop hearing about Keratin hair straightening. With all this talk you might be trying to decide for yourself whether or not it’s a good idea. We’ve compiled a list of pros and cons that should help you make up your mind.


Less Frizz

Hair is left silkier and more manageable. It will not get frizzy due to humidity. The best part is that the straightening process is not permanent unlike the familiar Japanese straighting. If your hair is wavy or curly, it will still be that way after the treatment, but it will be smooth and manageable no matter the weather.


It’s not recommended that you go in chlorinated or salt water after the treatment as this could cause it to wash out much quicker. Obviously, this may put a bit of a damper on vacation plans or summer getaways.

All Hair Types Welcome

Keratin treatments can be performed on any hair type – bleached, dyed, treated, you name it. It is also said to repair damaged hair and leave it silkier to the touch, which is a huge plus for those with dry or coarse hair.

No Awkward “Growing out” phase

Japanese straightening is permanent, so that means that as hair grows out your roots will return to their natural state while the rest of your hair remains pin straight. Not exactly a hot look. Keratin treatments only last a few months so you never have to worry about what your hair will look like as it grows out.



The treatment usually costs around $300 to upwards of $500 depending on where you get it done and how much hair you have.

Not Permanent

We consider this both a pro and a con, depending on what your needs are. Given the costs mentioned above, the fact that the treatment may only last a month or so could be considered a major drawback.


The process takes anywhere from 2 to 5 hours, depending on hair length. That’s a lot of time in the salon chair! So bring a couple of great magazines to keep you company!

Virgin Hair

The treatment will not last as long on virgin hair

Hair Products

You will need to avoid hair products that contain sodium chloride. This may mean changing from your favorite brand and using products that might leave hair feeling slightly less clean.
