Understanding Keratin Hair Treatments



Keratin hair treatments are a common method for attaining sleek, shiny hair. This treatment, also known as a Brazilian blowout, is a semi permanent hairstyle that can last up to six months. Although it can be costly, many people believe that the benefits justify the expense.

Keratin hair treatments, according to proponents, make hair more manageable and frizz-free. However, these products have the potential to cause side effects such as scalp and eye irritation.

This article examines keratin hair treatments in greater detail, including their benefits and costs. In addition, we discuss safety concerns regarding their use.


A keratin hair treatment is a method for smoothing and straightening frizzy or damaged hair.

Keratin is a naturally occurring protein produced by the body. It helps give hair, skin, and nails structure and strength.


The medulla is located in the core of the hair fiber and is only visible in hairs that are larger or thicker.

This is the primary component of hair. It is composed of proteins and provides structural support.

This thin outer protective layer is composed of keratinized cells that overlap like scales.

Keratin forms a long helical chain within the cortex with the aid of chemical bonds such as ionic bonding, disulfide bonding, and hydrogen bonding.

Additionally, weaker forces of attraction between molecules can aid in maintaining the a-helical structure of keratin. These helical filaments form filaments, which make up the majority of the cortex. The chemicals in keratin hair treatments alter the structure of keratin strands.

A stylist applies a keratin-based product to the hair and then seals it with a flat iron during a keratin hair treatment.

As the chemicals diffuse into the hair, they alter the cross-linking of the keratin strands based on the hair’s thickness and length. The combination of chemicals, blow-drying, and flat ironing speeds up the cross-linking process and straightens curly or wavy hair.


After a keratin hair treatment, the hair should not be washed for at least two days. Also, they should avoid:

  • They are wearing their hair in tight styles.
  • Utilizing unsuitable shampoos and conditioners.
  • Exposing their hair to chlorinated or salt water.

Additionally, it is essential to utilize sulfate-free shampoo and conditioner to prolong the treatment. These items are widely accessible in beauty supply stores, on the Internet, and hair salons.

People should avoid over-washing their hair, as doing so can remove the keratin treatment. Instead, you should aim to wash your hair every 3–4 days with lukewarm water. Applying a leave-in conditioner can also aid in protecting the hair and maintaining its suppleness.

Use a lower heat setting when blow-drying to prevent hair damage, and apply a heat protectant before using any hot styling tools.

It is also recommended to wait at least two weeks before coloring the hair after a keratin treatment. This allows the treatment to set and protects the hair from damage.

The results of keratin hair treatments can last for at least 12 weeks. However, the results will fade over time, and the treatment will need to be repeated to maintain straight, smooth hair.

If a dry and itchy scalp is one of your hair woes, an in-salon scalp treatment can be a helpful service that not only feels great, but also significantly corrects scalp oil production and promotes the use of the best shampoo for hair growth faster.

A healthy scalp is essential for healthy hair, regardless of whether your fine hair is weighed down by an oily scalp or prone to flaky patches. Massages for the scalp are gaining popularity as a result of the improved scalp skin they produce. Such brands as Aveda and Phyto offer complex cocktails that exfoliate the scalp and eliminate buildup.

It is perfect for everybody. Scrubs and serums for the scalp are the new hair skin care.

The lasting effects of keratin hair treatments are a significant advantage. They can significantly reduce the time spent every day styling the hair, especially if the hair is frizzy or thick. The effect can last for at least 12 weeks.

Additionally, some people no longer need to use heat to style their hair. This is due to the fact that following treatment, hair dries naturally straight and glossy.

Is the therapy risk-free?

Because they contain formaldehyde or other formaldehyde-releasing chemicals, keratin treatments have been the subject of some controversy. Formaldehyde is an odorless, colorless gas with toxic properties.

Formaldehyde may be harmful to a person’s health if inhaled or if it makes contact with the eyes or skin.

The adverse effects might include:

  • Irritation
  • Coughing
  • Wheezing
  • Nausea
  • Vomiting
  • Headaches
  • Dizziness
  • Allergy symptoms
  • Chest pain

Repetitive exposure to high levels of formaldehyde is also linked by experts to certain types of cancer, including leukemia. However, additional research is required to determine the relationship between formaldehyde exposure and leukemia.

hair treatment product  claims to be formaldehyde-free. However, they use methylene glycol or other chemicals that, when heated, may emit formaldehyde. This indicates that even if formaldehyde is not listed as an ingredient, people may still be exposed to the chemical.

The Cosmetic Ingredient Review Expert Panel has established a formaldehyde concentration limit of less than 0.2%.

Nonetheless, some Brazilian keratin treatments may contain significantly higher concentrations, in some cases more than five times the recommended level.

According to the Environmental Working Group, Brazilian-style keratin treatments with formaldehyde or alternatives to formaldehyde are unsafe.

Moreover, keratin hair treatments can cause damage to the hair. Therefore, individuals should limit their use and avoid repeated contact with harsh chemicals and heating elements.

Pregnant women are also cautioned against using keratin hair treatments.



Keratin hair treatments smooth the hair, resulting in a shiny, frizz-free appearance. People claim that it can make hair easier to manage. Although these treatments are expensive, their effects can last for several months.

However, despite their popularity, there are risks associated with keratin hair treatments. Most contain formaldehyde or other substances that may cause formaldehyde to be released. These chemicals can cause adverse reactions, such as coughing and vomiting.
