How to take care of hair post keratin treatment

post keratin hair care tips

Taking good care of your hair after receiving a Keratin treatment can mean the difference between hair looking healthy and glossy or having lackluster and dull locks. 

To ensure your hair is looking its best, there are a few things you should do to maintain the results of your Keratin treatment. 

First and foremost, it is important that you avoid getting your hair wet for the next three to four days post-treatment.

This is essential in order to permit the treatment to properly set. Additionally, you should avoid over-brushing and toweling your hair so as to keep these proteins in place and help preserve your freshly treated locks. 

When blow-drying your hair post-Keratin, it is important to use a professional grade hairdryer, preferably one with multiple settings. This will ensure that your hair is protected while it is being dried. 

Furthermore, a brush should be used to assist in the blow-drying process. A wooden comb is ideal as it provides a light and basic grip to the hair strands. Additionally, aim for low heat settings and medium to high speed when drying your hair.

Using a flat iron or hair curl iron is not recommended, but if absolutely necessary, use a titanium or ceramic flat iron at a low heat setting. 

Excessive heat may damage your hair, so be sure to always use the lowest possible heat setting.

By following the above steps, you can ensure your hair will stay looking and feeling healthy after a Keratin treatment. Keep in mind that for the best results, you should visit a professional hairdresser who has experience in applying Keratin treatments. 

Additionally, be sure to use a high-quality and preferable sulfate-free shampoo and conditioner specifically formulated to prevent breakage. With the right care and attention, you can enjoy silky and nourished hair all year round!

How long does keratin hair treatment take to settle?

Keratin hair treatments can take some time to settle in and take full effect, so you want to make sure that you give it enough time to work its magic. 

Depending on the type of hair that you have and the product you are using for your keratin treatment, it can take anywhere from three to five days for the treatment to settle and reach its full potential.

You may experience a few days of somewhat frizzy hair, but this is normal and expected. This is just part of the process of the keratin treatment settling in and taking effect. 

During this time, you should stay away from any heat styling tools such as blow dryers or flat irons so that you don’t disrupt the treatment and it can take full effect.

When the keratin treatment has settled, you can then blow-dry your hair as normal. As you continue to use the keratin treatment, you should blow-dry your hair a little less often and use it more as a touch up tool.

After all, the main point of the keratin treatment is to reduce the amount of styling you will have to do to get the perfect look, so frequent heat styling will counter that.

It’s important to remember that the process of letting the keratin treatment settle in can take around three to five days, so be sure to take the proper steps and wait it out before you start blow drying or styling your hair to make sure that the keratin treatment takes full effect.

How often should I wash my hair after keratin treatment

When it comes to caring for your hair after a keratin treatment, the number one priority is to make sure you give yourself plenty of time for the treatment to do its work. 

That being said, it’s also important to consider how often to wash your hair. The general guideline is to wait at least three days before washing your hair after the treatment. 

Throughout that time, it’s recommended to use a gentle cleansing shampoo instead of a harsh one. The reason being that after the keratin treatment, your cuticles are semi-open and can still be chemically altered if you’re using harsh products.

When you wash your hair after the keratin treatment, make sure to avoid shampooing too often. Doing so can potentially strip away the nourishment and strength that the keratin treatment has provided.

Instead, find a delicately formulated shampoo, and use it only when your hair starts to feel extra greasy or dirty. You should also consider investing in a good deep-conditioning treatment to further protect your locks from drying out and splitting.

It’s important to realize that although the initial keratin treatment is done, the process does not end there. 

Washing your hair too often with the wrong type of products can give way to complicated issues such as porous hair, color fading, and even breakage. Over-washing can also increase your hair’s vulnerability to external factors such as humidity and heat. 

Following these washing guidelines can help extend the life of your keratin treatment and help you achieve the smooth hair of your dreams much sooner.
