Many women love having straight and sleek mane for diverse reasons. It is easy to maintain and gives you a sophisticated look among others. This does not mean you cannot rock wavy and curly hair. They are lovely but they need extra attention to tame flyaways and frizz in your mane.
If you need to change the structure of your curly mane, hair straightening and smoothing treatment help with that. These two treatments help keep your tresses straightened and give them a polished look. Even though they serve the same purpose, they vary in how they work.
This article will discuss the differences, side effects, and maintenance tips for the two treatments. But before then, what is hair straightening and hair smoothing?
Hair straightening has been around for a while compared to hair smoothing. There are two types of hair straightening and they are temporary and permanent hair straightening.
Temporary Hair Straightening
For this type of hair straightening, you straighten your mane using hot tools such as flat iron or styling comb. However, straight hair is temporary because it goes back to the original structure once you wash your lock. Besides, exposing your hair to heat can damage your mane. Thus, temporary hair straightening can cause hair damage.
Permanent Hair Straightening
This involves using chemicals such as relaxers to change the structure of your tresses. It can quickly change your wavy hair into polished straight and sleek hair in seconds. It is called permanent hair straightening because it lasts about 8 to 12 weeks. Even if you wash your hair, it remains intact until new hair grows out.
Hair straightening works on different types and structures of hair. However, the chemicals in the relaxer do not go well with bleached hair. Hence, you should avoid it if you have bleached your hair. How long hair straightening treatment lasts on you depends on the texture of your mane.
Side Effects Of Hair Straightening
As good as hair straightening is, it has some side effects. Thus, here are some side effects attached to hair straightening treatment.
- Chemicals in the relaxer burn the skin, therefore it should not be applied directly to your skin. To ensure this, apply petroleum jelly or hair cream around your hairline.
- Relaxers cause frizzy hair and even hair thinning and weakening.
- It can also cause hair loss and dandruff.
- The wrong application of relaxers can cause hair damage and breakage.
Many people consider hair smoothing as part of hair straightening treatment. Hair smoothing involves using a solution known as formaldehyde to moisten the hair. Then you use a flat iron to seal your mane in a straight position. It leaves your hair smooth, shiny, and frizz-free.
This technique is temporal but it lasts longer than temporary hair straightening. It can last up to 3 months. Hair smoothing is not effective for all hair textures, it works well on thin hair but not so well on thick curls.
Side Effects Of Hair Smoothing
Even though it is less damaging than hair straightening treatment, it also has some side effects.
And here are some;
- Formaldehyde solution burns the eyes and irritates the nose.
- Another side effect is that it triggers nervous system problems. Thus, it can cause nausea, dizziness, and so on.
- Besides, the heat from using flat iron during the process can cause hair brittleness, damage, or breakage.
