Keratin treatment is a hair smoothing treatment that uses a keratin protein-based formula to smooth and straighten hair. The treatment is applied to the hair and then sealed in with heat, typically from a flat iron. The heat activates the keratin protein, which bonds to the hair, leaving it smooth and frizz-free.
The treatment is typically used on curly, frizzy, or unruly hair to make it more manageable and easier to style. It can also help to reduce the amount of time it takes to style your hair, as well as make it more resistant to humidity and frizz.
Keratin treatment can be done in a salon by a professional stylist, or at home using a keratin treatment product. The treatment typically lasts for about 3-6 months, depending on the type of keratin treatment used, the condition of your hair, and how often you wash your hair.
It’s important to know that keratin treatment contains formaldehyde, a chemical that can be harmful if inhaled. Some keratin treatments have been reformulated to be formaldehyde-free, but it’s important to check the ingredients before undergoing the treatment.
Keratin treatment at home
Keratin treatment can be done at home using keratin treatment products, which are widely available at beauty supply stores and online. These products typically come in the form of a cream or liquid and are applied to the hair in sections, using a brush or comb. The hair is then sealed in with heat, typically from a flat iron.
When doing a keratin treatment at home, it’s important to follow the instructions provided with the product carefully. It’s also important to use heat-protective gloves and a heat-protective mat to prevent burns or other accidents.
It’s also important to note that keratin treatments at home are not as effective as those done in a salon by a professional stylist, and may not last as long. Additionally, at-home keratin treatments may not be suitable for all hair types and can cause damage if not done correctly. It’s best to consult a professional stylist before doing a keratin treatment at home, and have a patch test done if you are not sure about the suitability of the treatment for your hair type.
Some keratin treatment products may contain formaldehyde, a chemical that can be harmful if inhaled. Therefore, it’s important to check the ingredients before undergoing the treatment and make sure to have proper ventilation while doing the treatment.
It’s recommended to use a clarifying shampoo before the treatment, to remove any buildup and to make sure that the treatment will be effectively absorbed by the hair.
Keratin treatment side effects
Keratin treatment is a hair smoothing treatment that uses a keratin protein-based formula to smooth and straighten hair. While it can be beneficial for some people, it can also cause certain side effects. Some of the most common side effects of keratin treatment include:
- Allergic reactions: Some people may be allergic to the ingredients used in keratin treatments, which can lead to itching, redness, and other symptoms of an allergic reaction.
- Hair damage: If not done correctly, keratin treatment can cause damage to the hair, such as dryness, breakage, and split ends.
- Scalp irritation: The keratin treatment can cause itching, redness, and other symptoms of scalp irritation.
- Breathing issues: Some keratin treatment contains formaldehyde, which can be harmful if inhaled. Inhaling formaldehyde can cause breathing issues such as coughing, wheezing, and shortness of breath.
- Discoloration: Keratin treatment can cause discoloration of the hair, especially if it is done frequently or on already treated hair.
- Fading of color: Keratin treatment can cause fading of hair color, especially if it is done frequently or on already treated hair.
These side effects are more likely to occur if the treatment is not done correctly or if the hair is not in good condition before the treatment. It’s best to consult a professional stylist before undergoing the treatment, and have a patch test done if you are not sure about the suitability of the treatment for your hair type.
Keratin treatment of curly hair
Keratin treatment can be used on curly hair to make it more manageable and easier to style. The treatment uses a keratin protein-based formula to smooth and straighten hair. It works by bonding the keratin protein to the hair, which helps to tame frizz and reduce curl.
When done on curly hair, the treatment can help to reduce the amount of time it takes to style your hair, as well as make it more resistant to humidity and frizz. The treatment can also help to add shine and a healthy look to the hair.

Keratin treatment before and after
A keratin treatment can have a significant impact on the appearance and manageability of hair. Before undergoing the treatment, hair may be frizzy, unruly, and difficult to style. After the treatment, hair will appear smoother, shinier, and more manageable.
Before the treatment, curly hair may have a lot of frizz and may be difficult to straighten or style. After the treatment, the hair will appear more defined, with less frizz, and will be more manageable and easier to straighten or style.
The length of the results of a keratin treatment can vary depending on factors such as the type of treatment used, the condition of the hair, and how often the hair is washed. On average, the treatment can last from 3-6 months.
Keratin treatment can cause damage to the hair if not done correctly. It’s important to choose a reputable salon and stylist, and make sure that the stylist is well-trained in the use of keratin treatment. Additionally, it’s important to use a deep conditioning treatment after the keratin treatment to keep the hair moisturized and prevent dryness, breakage, or split ends. Also, it’s important to use sulfate-free shampoos and conditioners after the treatment to maintain the treatment’s results and to avoid damaging the hair.
Keratin treatment process
The process of a keratin treatment typically includes the following steps:
- Consultation: A professional stylist will consult with you to determine if a keratin treatment is the right choice for your hair type and desired results. They will also check for any allergies to the ingredients used in the treatment.
- Shampoo: Your hair will be washed with a clarifying shampoo to remove any buildup and ensure that the treatment will be effectively absorbed by the hair.
- Application: The keratin treatment product is applied to the hair in sections, using a brush or comb. The product is then worked through the hair, making sure that all of the hair is covered.
- Processing time: The hair is then left to process for the amount of time specified in the instructions for the product. During this time, the keratin protein bonds to the hair, leaving it smooth and frizz-free.
- Heat sealing: The hair is then sealed in with heat, typically from a flat iron. The heat activates the keratin protein, which bonds to the hair.
- Styling: The hair is then styled as desired.
- Wash: The hair should not be washed for at least 72 hours after the treatment to allow the keratin protein to fully bond to the hair.
