What Is Keratin Treatment And How It Works?
A keratin treatment is a hair smoothing treatment that uses a combination of chemicals and heat to temporarily straighten hair and reduce frizz. The treatment typically lasts anywhere from 3-6 months, depending on how often you wash your hair and the quality of the treatment.
When it comes to washing your hair after a keratin treatment, the first thing you need to know is that you cannot wash your hair for at least 72 hours after the treatment. This allows the keratin to fully penetrate your hair and provide the best results possible. After 72 hours, you can begin to wash your hair, but it’s important to do so in a gentle manner to avoid damaging the treatment.
What Are The Reasons For Being Cautious While Washing Hair After A Keratin Treatment?
It’s important to exercise caution when washing your hair after applying keratin treatment for the first time. This is because the keratin requires ample time to penetrate the hair shaft and deliver its beneficial effects.The objective is to allow the keratin treatment to remain on your hair for as long as possible, which can make the initial wash a bit challenging. However, there are several helpful tips to ensure that your first hair wash after the treatment is successful.
What Is The Ideal Timing For Washing Your Hair Following A Keratin Treatment?
For best results, it is recommended to wait for a period of 3-4 days following a keratin treatment before washing your hair. This waiting time ensures that the keratin treatment is given ample time to settle and effectively bond with your hair.
In case of an urgent need to wash your hair before the recommended 3-4 days after keratin treatment, it is advisable to wait for a minimum of 12 hours. The appropriate waiting period before washing your hair post-treatment is largely dependent on variables such as the type and amount of keratin treatment applied and your hair type. To avoid any potential harm to your hair or interference with the treatment’s efficacy, it is always advisable to consult your stylist to determine the ideal waiting time for washing your hair.
How should you dry your hair after a keratin treatment for best results?

A recommended approach for eliminating surplus water from your hair is to dab it gently with a towel and subsequently allow it to dry naturally. To preserve your Brazilian blowout, it is advisable to refrain from utilizing a hairdryer, since the high temperature could cause harm. However, if it is necessary to use a hairdryer, it is recommended to utilize the lowest heat setting possible. If your hairdryer is equipped with an air-only option, it would be even more beneficial.
What are the potential side effects of undergoing a keratin treatment?
Keratin treatment, also known as Brazilian Blowout or smoothing treatment, is a popular hair treatment that is used to make the hair smoother, shinier, and more manageable. While the treatment can have many benefits, it can also have some side effects. Some potential side effects of keratin treatment include:
- Dryness: Keratin treatment can cause the hair to become dry, especially if the treatment is done too frequently or if it is not properly moisturized after the treatment.
- Scalp irritation: Some people may experience scalp irritation or itching after a keratin treatment, especially if they have sensitive skin.
- Allergic reactions: Some people may have an allergic reaction to the chemicals used in the keratin treatment, which can cause redness, swelling, and itching.
- Hair breakage: Overuse of keratin treatment can lead to hair breakage, especially if the treatment is done too frequently or if it is not done by a trained professional.
- Formaldehyde exposure: Some keratin treatments contain formaldehyde, a chemical that has been linked to cancer and other health problems. Formaldehyde exposure can cause respiratory problems, eye irritation, and other health issues.
It is important to note that not all keratin treatments are created equal, and some treatments may be safer and more effective than others. It is important to research different keratin treatments and choose a reputable salon and stylist who is experienced in the treatment.
Tips for washing your hair after a keratin treatment
- Use a sulfate-free shampoo:
Sulfates are harsh chemicals that can strip the keratin treatment from your hair. Using a shampoo that is free of sulfates and gentle on your hair is crucial. Look for shampoos that are specifically designed for keratin-treated hair, as they will be formulated to help maintain the treatment.
Since you have already taken the step to enhance the appearance of your hair, it is essential not to compromise on using other hair care products. Also, you can try out Keratin Complex Smoothing Therapy Color Care Duo, as it’s enriched with Provitamin B5, provides hydration and smoothness to hair, formulated without sulfates.
2. Wash your hair less frequently:
The less you wash your hair, the longer your keratin treatment will last. It is recommended to limit hair washing to a maximum of twice a week. On days when you don’t wash your hair, use a dry shampoo to absorb any excess oil and keep your hair looking fresh.
3. Use lukewarm water:
Hot water can also strip the keratin treatment from your hair, so it’s important to use lukewarm water when washing your hair. This will help to maintain the treatment and keep your hair looking smooth and frizz-free.
4. Be gentle:
To avoid causing damage, it’s important to wash your hair gently and refrain from scrubbing it too aggressively. Use a gentle massaging motion to work the shampoo into your hair and scalp, and rinse thoroughly with lukewarm water.
5. Avoid using conditioner:
While it’s important to keep your hair hydrated, using a conditioner after a keratin treatment can weigh down your hair and make it look greasy. Instead, try using a leave-in conditioner or hair oil to keep your hair hydrated and looking its best.
The Bottom-Line
To maintain the effects of a keratin treatment, it’s important to follow specific guidelines when washing your hair. Wait at least 72 hours after the treatment for best results, but if you need to wash your hair urgently, wait for 12 hours and use sulfate-free shampoo. Limit washes to twice a week, avoid conditioner, and consult your stylist for optimal results.
