Smooth and straight hair is becoming increasingly fashionable and hence, hair straightening salons are always busy. Straight hair is less difficult to manage than wavy or curly hair. While there is no question that curly hair is stunning, many ladies do not have the time to manage it. This is why hair straightening clinics and smoothing treatments are becoming increasingly popular.

However, many women who desire to get rid of curls and frizz are unaware of the distinction between hair smoothing and straightening. In this post, we will look at how these two variables, as well as their negative effects.

What exactly is hair smoothing?

Hair smoothing is a procedure that uses chemicals to smooth your hair. Some people classify it as a hair straightening treatment since it temporarily straightens your hair. However, because the treatment is not as powerful as hair straightening treatments, it is less harmful and has a shorter duration.

What exactly is hair straightening?

In layman’s terms, hair straightening is the procedure of straightening your hair. Permanent and temporary hair straightening procedures are available. Temporary hair straightening is accomplished with hair straightening equipment such as a flat iron. This straightens your hair, but after you wash it, it returns to its original state. Permanent hair straightening, on the other hand, is the process through which your hair structure is broken down and straightened using chemicals. This is a long-lasting treatment that does not wash away with a single wash.

Hair Smoothing Side Effects

Wavy and frizzy hair responds well to hair smoothing treatments. This is due to the fact that it does not have to use too much effort to realign the hair structure. It may not even work on extremely thick and curly hair. Its effects might persist for up to two or five months.

Hair smoothing, like any other hair treatment, has a few negative effects. Formaldehyde releasers are used in hair smoothing treatments. Formaldehyde is a carcinogen that causes eye irritation, nervous system difficulties, nausea, respiratory tract problems, vomiting, chest discomfort, and rashes. It’s also a known carcinogen. It also increases the likelihood of getting asthma. Furthermore, because of the use of chemicals and heat in this treatment, it might cause hair damage if done excessively.

Hair Straightening Side Effects

Hair straightening is a more powerful procedure than hair smoothing and coloring. As a result, it is suitable for all hair types, including particularly thick and curly hair. Depending on the kind of hair, the treatment must be repeated. It would mostly need to be repeated every 8 to 12 weeks.

Hair straightening, like hair smoothing, has several drawbacks. It employs chemical relaxers that, if administered to the scalp, can cause it to burn. If not done correctly, it can potentially cause hair breakage. It also causes hair to lose strength as a result of the enlargement of hair fibers and the opening of cuticles. Additionally, this therapy is reported to cause frizzy hair, hair thinning and loss, dandruff, graying hair, and split ends.


Both therapies have advantages and disadvantages. If you are unsure about the treatment to choose, simply ask yourself the following questions.

Are you searching for a long-term or short-term solution?

Do you wish to get rid of frizz or just straighten your hair?

Do you want your hair to be perfectly straight or natural?

The answers to these questions will help you determine whether you should receive a keratin treatment or a smoothening treatment from a keratin treatment salon Potomac. Just make sure these procedures are performed by an expert! Otherwise, you might simply be risking your money.
