Now that you have achieved those super soft and bouncy hair from your keratin treatment, you have to know certain things about how to make it last longer. There are a lot of after-care treatments required if you have undergone keratin treatment and today, we will be talking about what not to do after a keratin treatment and all the other care tips that you need to know. Let’s get started!

10 Things Not To Do After Your Keratin Treatment

Your hair stylist might probably give you some tips and recommendations on how to care for your hair after your keratin treatment. But, here are some of the most important things that we need to emphasize to help you enjoy your pretty hair longer.

By the way, try out my favorite Non Sulfate Lemon + Tea Tree shampoo. You will not regret how smooth this natural aloe vera mix is.

First thing that you need to know is that post-treatment care is vital within 72 hours after your treatment is done. This is the key to long-lasting results for your keratin treatment. 

Don’t Wash Your Hair – Yet!

Yes, you had a very long and hot day today and it’s sad that you cannot wash your hair after your treatment. Don’t worry, you can still enjoy a nice bath after your keratin treatment – just make sure not to wet your hair!

You can always put on a shower cap like AmazerBath Shower Caps for Women to protect your hair from the water. This shower cap is made from reusable and durable materials, so you can reuse it anytime you want!

Don’t Wash Your Hair Everyday

Now that a few days have passed, you can start washing your hair already. But that doesn’t mean that you need to wash it everyday. Make it a habit to wash your hair at least every other day.

I know this might feel icky and bothersome to most people, but one of the best ways to not wash your hair everyday is to use a dry shampoo. Dry shampoos allow you to clean your hair without even rinsing it. You would still feel fresh and clean even after a long day!

One of the most-sought dry shampoo brands is OGX, and OGX Refresh Revitalize Extra Strength Dry Shampoo is a real deal for people who have undergone keratin treatment. This dry shampoo effectively absorbs all the oils that have accumulated on your hair.

This product can keep you feeling fresh and clean between washes. It is also infused with Moroccan oil and silk proteins to keep your hair smooth and silky even without rinsing it off with water!

Don’t Tie Your Hair

Even if it’s super hot, refrain from tying your hair and tucking it behind your ears. This could create some dents on your newly-treated hair, so be careful! It is also best to sleep with your hair loose at night.

Wearing headbands and tying your hair up with sunglasses are also part of this reminder. Using these accessories can create bends and dents on your keratin-treated hair hair, which would make you want to straighten it up using a flat iron – which is also a no no!

Skip Cheap Shampoos

One of the most important things not to do after your keratin treatment is to use cheap shampoos. You always have to be very careful before selecting your shampoos and conditioners. 

Your keratin-treated hair needs very mild shampoos that also contain micro keratin. This ensures that the treatment will be locked in on every strand of your hair. Always check the label and skip out shampoos that contain sulfates and sodium chloride (salt).

The reason behind refraining from sulfates is that they deplete the natural moisture barriers or your hair and scalp. As for salt, they are very coarse in texture and can make hair look frizzy. It also dissolves the keratin ingredient from your treated hair. Here are some of the best choices of shampoo after your keratin treatment:

Arvazallia Hair Repair Set

One of the best shampoo and conditioner for keratin-treated hair is this Arvazallia Hair Repair Set. This professional set of products deeply conditions your treated hair to ensure that it will always stay soft and smooth.

It doesn’t contain sulfates and other harsh chemicals that can affect and damage your hair. This 3-piece kit includes a shampoo, a daily conditioner, and a hydrating mask – suitable for all hair types.

It is also safe enough to be used daily, and the ginger oil ingredient of this shampoo and conditioner.

No Coloring Within 3 Weeks

No matter how badly you want to have those bright and vibrant colors for your hair, it is best to wait up to 3 weeks before dyeing your hair. If you color your hair within 3 weeks after you have just had keratin treatment, the pigments of the hair dye won’t penetrate your strands as it is supposed to.

The best time to have your hair colored is before you have keratin treatment. The keratin ingredient gives a protective coating on your hair, which makes the hair color less likely to fade.

Don’t Bleach Your Hair

Just like mentioned above, you should not be coloring your hair within 3 weeks after your keratin session. And this also includes not bleaching your hair too! Bleaching your hair within 3 weeks can seriously damage your hair because of its corrosive properties. It can make your hair feel like it’s been fried!

Stay Away From Heat 

Blow dryers, heated curling irons, and flat irons can really make all your money spent go to waste when used on a keratin-treated hair. Heat can melt the keratin applied on your hair, and we highly recommend sticking to 365°F of temperature if curling and straightening is badly needed.

Moreover, you can also use heat protective sprays like the CHI 44 Iron Guard Thermal Protection Spray. This product contains a formula that helps you get a sleek and smooth hairstyle without worrying about heat damage.

It works from the inside and out – protecting every strand of your hair from potential damage caused by your reliable irons. It also seals the cuticle to prevent further damage on your hair and scalp.

Don’t Use So Much Hair Products 

We get it – you used to apply hair mousses, leave-in conditioners, hairsprays and other hair products to keep your hair nicely styled. But after your keratin treatment, you honestly don’t have to overdo hair products anymore.

Overusing hair products can create chemical build-up on your hair which would make you want to wash your hair more often. Remember that it is not recommended to wash your hair daily since it would strip away the keratin treatment applied.

Don’t Touch Your Hair So Much

Did you know that it is also forbidden to touch your hair too much after just having your keratin treatment? Frequently touching your hair can make it feel greasy and oily and it would make you want to wash it more often too.

In addition to that, it can also contribute to your hair getting kinky, making it more prone to frizz. So, just leave your hair be and enjoy it!

Don’t Use Heavy Oils

Heavy oils like coconut oil are advised not to be used if you have just done a keratin treatment. This oil penetrates deep into your follicles and they are difficult to wash off. But if you really love applying oil on your hair, you can choose some lightweight oils like the L’ANZA Keratin Hair Treatment Healing Oil. 

This is one of the most lightweight oils that I have ever encountered and it does not leave a very greasy feeling on the hair. It also rehydrates the hair, which is very important for keratin-treated hair.

The best part about this product is that it shortens your hair drying time, so it can reduce heat damage when you are always using a dry blower on your hair.
