After Keratin Shampoo – What To Look For
Keratin treatments help to give your hair a smooth, shiny, and sleek finish for a few months.
It is the secret to stunning hair (especially if you usually battle with frizz and dullness) and is a fairly accessible process (albeit sometimes expensive).
If you want to get a keratin treatment, it is essential to practice proper aftercare to ensure the treatment lasts as long as possible.
One key factor is choosing the right post-keratin treatment shampoo.
The wrong shampoo will strip the treatment from your hair!
To help keep your hair shiny, sleek, and smooth for longer, what is the best post-treatment keratin shampoo to look for?
After a keratin treatment, look for a shampoo free of sulfates and sodium chlorate. These can strip the hair of the keratin treatment, so your hair will not have that gorgeous shine for as long as it should.
The shampoo should also contain natural ingredients and be neither drying nor harsh on the hair.
A lot of it will come down to personal preference, but there are definitely some post-keratin shampoos that stand out from the rest. Here is how to choose them!
What Is A Keratin Treatment?
Understanding what a keratin treatment is will help you choose the best post-treatment shampoo and explain why it is so important to choose the right one.

A keratin treatment is a chemical process.
It is used to smooth hair and add shine, and is usually applied to frizzy hair to offer some control.
If properly cared for, keratin treatments can last up to 6 months.
There are a few different keratin treatments to choose from, and these all go by other names, such as a Brazilian Blowout, Goldwell Kerasilk, and more.
Hairstylists can also customise a treatment to suit your hair type.
Older versions of keratin treatments released formaldehyde when heated, but newer treatments are formaldehyde-free.
The basic process of keratin treatments involves injecting keratin into the hair follicle’s porous areas, reaching deep within to provide hair with this essential protein.
This makes hair healthier, shinier, and smoother. Your hair looks more nutritious because it is healthier!
What To Look For In A Post-Keratin Treatment Shampoo
It is so important to choose the right shampoo for post-keratin treatments.
Keratin treatments aren’t cheap, so you need to make sure you use the right product to help the treatment last as long as possible and to keep your hair healthy for as long as possible.
Choosing a shampoo for keratin-treated hair is pretty simple.
There are a few criteria that the shampoo has to meet, but the rest is quite up to personal choice.
Most importantly, the shampoo should be sulfate-free and sodium chlorate-free.
These two chemicals strip the keratin treatment from your hair, so it does not last as long as it should, which is quite a waste.
These chemicals also strip colour from colour-treated hair, so it is best to avoid them overall.
The remaining properties of the shampoo will depend on what you are looking for.
You might be more interested in all-natural products or shampoos formulated for sensitive scalps.
There are lightweight and heavy products, as well as those that lather and those that don’t.
It is also a good idea to look for shampoos that have natural vitamins.
These will work with the keratin treatment to provide your hair with strength, moisture, nutrients, and oils that keep it healthy and strong.
Avoid shampoos with sulfates and sodium chlorate, and choose shampoos with natural vitamins and oils to enhance your hair’s health!
The Benefits Of Using Post-Keratin Treatment Shampoo
There are quite a few benefits to using a post-keratin treatment shampoo, and you will definitely notice the difference when using the right product.
Nutrients & Moisture
Shampoos you can use after a keratin treatment are typically high-quality.
These will have the right amount of natural vitamins and oils to keep your hair healthy and strong while allowing keratin to do its job.
They do not contain synthetic fillers that can irritate the skin and dry out your hair and scalp.
These shampoos work to keep hair moisturised without providing too much product and chemicals.
Long-Lasting Treatment
By not containing sulfate or sodium chloride, good after-keratin shampoos will not strip the keratin from your hair.
This allows the treatment to last longer, giving you more time between treatments.
This can save you quite a bit of money in the long run.
Strength
The natural oils and vitamins in these post-keratin treatment shampoos help keep hair strong.
They strengthen the hair naturally so that it stands up to everyday wear and tear, heat, and breakage.

Can You Do A Keratin Treatment At Home?
Technically, you can do a keratin treatment at home, but it will never be as good as a salon treatment.
There are home treatments to buy that all contain the buzzword “keratin,” but these are not necessarily the right keratin treatments to use.
Many of the home treatment kits you can buy do not contain the right ingredients for a deep, intensive keratin treatment.
They may include silicone and conditioning treatments that give you that smooth, sleek look, but do not last as long and do not nourish your hair as a keratin treatment should.
There should be extensive instructions included with the kit that explain how to wash, dry, and heat-straighten your hair during and after the treatment.
If it does not contain these instructions, chances are that you have just bought a conditioning treatment that will be pretty short-lived.
While salon keratin treatments can be pretty pricey, they are definitely worth it if you are looking to have a proper keratin treatment done.
It will likely save you money in the long run by being longer-lasting and more nourishing for your hair, as long as you use the right post-keratin treatment shampoos!
Is it Necessary to Use Keratin Shampoo After a Treatment?
Yes, you do need to use a keratin-treated shampoo after your treatment.
It is the same as when you have your hair colored in the salon; you need to use shampoo and conditioner that will not strip this from your hair.
There is no point paying for a salon treatment and then not using the right shampoo to extend its life, making the therapy not worth it.

Do Shampoos With Added Keratin Actually Work?
Shampoos that contain added keratin help provide your hair with an extra layer of protection and condition it.
These shampoos also help to treat damaged hair and chemical buildup.
Keratin-enriched shampoos do offer some protection and shine for hair, but not on the same level as a salon keratin treatment.
You will also need to use these keratin shampoos often to maintain shine, whereas a salon treatment only needs to be done every few months.
Can Keratin Ruin Your Hair?
Some keratin treatments contain products that can actually damage your hair, even though they strengthen your hair as well.
This is because some chemicals in keratin treatments, such as formaldehyde, can damage hair.
The heat and styling tools used during a keratin treatment can also break and burn hair, further damaging it.
However, it is a catch-22 as the treatment also strengthens and nourishes hair.
When choosing your keratin treatment, research the best option for your hair and follow up with a nourishing shampoo and hair care routine.
