Permanent Hair Straightening Guide



The Process

All kinds of permanent hair straightening techniques work in the same way. The same strategies are used by every hairstyling expert. Here is the process in detail:

1.    Firstly, the hair is coated with a chemical solution. These chemicals are used for changing the configuration of the proteins present within your hair.

2.    If you are going for thermal straightening or perming, a neutralizer will be applied on your hair. It will help in locking the hair into a new shape. This would also lead to the formation of new bonds between your hair’s protein molecules.

The application of chemical solution and neutralizer followed by the styling of your hair may take a lot of time. The hair takes several hours for the chemicals to get infused properly.

Permanent Hair Straightening Cons

Permanent hair straightening does make the hair look amazing but it has its own set of side effects and cons. Let’s go through some of those:

1.    To get a successful permanent hair straightening treatment, you need to visit a highly experienced professional. This would cost you a lot and if you are not financially ready to spend so much on hair treatment, you must wait.

2.    Often, these solutions are heavily scented and you might be advised to keep your hair dry and save it from moisture, water, and sweat for a few days after the treatment. This would mean that you will inhale the chemicals all the time after your hair treatment and people around you will also get exposed to the scents.

3.    It is quite common to experience hair breakage after you get your hair permanently straightened. The chemical solutions damage your hair and make it look flat. Your hair may also release the natural curls.

4.    You will have a tough time styling your hair and it will take more time in drying. This will stop happening once your new, untreated hair starts to grow.

5.    Formaldehyde is present in almost every hair straightening solution. It is known for being a carcinogen. Inhaling the fumes or applying it to the hair can expose you to its side effects. You may experience irritation in your eyes and nose, respiratory difficulties, skin irritation, and/or redness.

6.    If you think your “all-natural” straightening products would do no harm, you are wrong. Products that claim to be natural or free of formaldehyde are loaded with duplicate chemicals which turn into formaldehyde when they get heated. Many keratin hair straightening methods have formaldehyde levels which were high enough for posing health risks to consumers.
