But now there are treatments and methods available which smooth your hair strands instead of straightening them. Such treatments not only make your hair smooth but also look sleeker and shinier.

Before going for straightening or smoothing, you need to know about both the methods in detail. Let’s discuss them in-depth.

What is Hair Straightening?


Hair straightening is a very popular method for getting sleek hair. There are basically 2 common methods of hair straightening including temporary and permanent. Temporary hair straightening is done with electric heating plates, tongs or combs. They are available under different renowned brand names. It doesn’t take much longer with these tools. The results of this straightening last until you wash your hair.

On the other hand, permanent straightening also known as Japanese Straightening involves chemicals that straighten your hair permanently. This is one of the new forms of straightening. Chemicals used in the process weaken and break the keratin bonds of curly hair. The heat used in the process stretches and restructures the bond. Thus your hair completely gains the new shape and become permanently straight.

How does Permanent Hair Straightening work?


Chemicals used in this process are called alkaline straighteners. These contain 1-10% concentration of either Sodium Hydroxide, Lithium Hydroxide or Calcium Hydroxide. These chemicals are called alkaline because they have high pH value which helps open up cuticles. Thus absorbed in the hair fibers, they react with keratin and break them down to restructure them. Processed hair becomes permanently straighten until new hair growth.

Everyone with a coarse and kinky hair type can go for the procedure. The procedure can be repeated after 8-12 months depending upon the need.

Cons of Permanent Hair Straightening:

  • Chemicals used in the process can damage your scalp so be careful while applying them on the hair strands. We suggest you to apply some petroleum jelly on the scalp line to prevent any damage
  • Heating can cause hair burn and breakage
  • Hair may lose their strength and original texture
  • Your hair may become frizzy, weak or may lead to hair fall as well. other side effects involve dandruff and graying of hair too soon

Hair Smoothing:

The procedure is also sometimes known as hair straightening. But this is quite a different method and has temporary results. It also involves chemicals usually called formaldehyde which is applied on the hair strands. According to, the chemical is dried out by using flat iron thus the chemical locks in the hair strands and make them straight. The difference between permanent straightening and smoothing is that the chemicals used in this procedure are less damaging. They are not that strong the way used in permanent straightening. One of the famous forms of this treatment done is called Brazilian Keratine Treatment.

Results for this treatment last for about 2-5 months. But the treatment doesn’t work well for kinky and too curly hair. Most of the time, it is only used to deal with the frizz.

Cons of the Treatment:

  • Formaldehyde can possibly cause burning in the eyes, nose and mouth. Other side effects might include headache, dizziness, nausea, vomiting and even rashes
  • Serious problems may include the risk of asthma
