Are Straightening Shampoos Bad for Your Hair?


Generally speaking, straightening shampoos are not at all bad for your hair.

What sets them apart from regular shampoos is that most straightening shampoos have smoothing agents that stick around after rinsing. This gives it that long-lasting frizz control effect and weighs them down to make it naturally fall instead of frizzing out.


Although, because of the higher levels of ingredients such as silicone, some hair straightener products might weigh down your hair too much because of all the residue that builds up. This can make your hair feel greasy, dirty, and irritating to carry around.

This is why it’s important to know how to use these kinds of shampoos and what’s best for you.

A common hair-straight product feature from Silicone is that they prepare your hair before you do other straightening techniques like using a blow dryer or flat iron.

The conditioning agents that settle on your hair after you rinse help protect it from heat and make your straightening techniques more effective.

The silicone-based ingredients that are present in some straightening shampoos are activated with heat. This ingredient creates a microfilm around the hair shafts that helps lock in moisture.

Not only will that prevent your strands to absorb moisture from your environment, but it will also help speed up the heating process of your flat iron or blow dryer, reducing the chances of heat damage.


One thing to keep in mind when it comes to straightening shampoos is that the presence of sulfate might do more harm than good. Sulfates are present in a lot of shampoos in general because they help make the lather more luxurious and effective at cleaning.

Although, a lot of shampoos that don’t have sulfate can lather and clean your hair and scalp just as well.

Sulfate isn’t necessarily a bad thing, but if you have damaged hair, treated and colored hair, or dry hair as is, using shampoos with sulfate could strip away even more natural oil in your hair and make them worse.

To sum it up, hair straightening shampoos get rid of frizzy and flyaway hair and makes them silky, shiny, and smooth compared to regular cleaning shampoos. It makes it easier to manage your hair as it reduces knots, and it also preps your hair for heated styling tools.

On the other hand, straightening shampoos that are not used correctly can lead to greasy and itchy hair and scalp. The microfilm that’s left behind from silicone-based straightening shampoos is sometimes hard to get rid of.

A strong sulfate solution would usually do the trick to cleanse this smoothing agent off, but that could also lead to very dry and damaged hair. This is also why sulfate-based products are good at removing hair dye from hair.

Make sure to use a good moisturizing conditioner right after if you end up in this situation. 

What Shampoo Makes Your Hair Smooth and Straight?


When looking for hair straightening shampoos, you don’t necessarily have to look for hair care products that have certain ingredients.

Although silicone, keratin proteins, and other artificial ingredients can contribute to making your mane smooth and straight, natural ingredients that are mixed and used well together can get the job done just as well. It may even be gentler and safer for all hair types!

Artificial Ingredients

It’s generally believed that products with artificial ingredients are more effective at what they do compared to natural ones.

For a long time, this has been a common belief, but as time passes by, a lot of all-natural shampoos are getting results that are just as great, or even better than some artificial shampoos!

Are straightening shampoos with artificial ingredients bad? Not at all! These kinds of products have been tried and tested in the market for so long and a lot of them give real results. It’s just that natural shampoo options have been JUST AS GREAT and can be a good pick up as well.

When deciding what kind of straightening shampoo is best for you, keep in mind that it doesn’t always just come down to if it’s all-natural, artificial, or mixed. Take into consideration your personal hair situation and see what works best for you!

If you still need to know more about how a certain shampoo gives you smooth and straight hair, the list we provided highlights the key ingredients that are present in the shampoo that makes them stand out.

Take a look and see why some artificial ones are great, why some all-natural ones are just as effective, and how some mixed ones can give you the best of both worlds.

What are the Best Products for Straightening Hair?

The best straightening-for-hair shampoo product will depend largely on your situation.

To make things easier for you, we’ll discuss the effects of some ingredients and how they might be perfect for your hair care.

Overall, the best hair straightening shampoos contain key ingredients with a clear purpose.

Keratin protein is a great option to go with, but going for a natural straight-shampoo with nourishing oils is also a great option.

At the end of the day, it’s important to notice these key ingredients for your own hair care.

The best hair straightening solution for you would depend on how your hair reacts to the ingredients that are on the shampoo.

Keratin-Based Products

Keratin is a popular ingredient that’s associated with hair straightening shampoo. Keratin is a type of protein that makes up your hair, skin, and nails.

It’s a building block for your hair, and this protein is important because it makes your hair more resistant to damage.

Using a straight-hair-product that contains keratin also protects your hair from heat damage.

This is perfect for those who are looking to really straighten their hair out by using heat styling tools such as a blow dryer or flat iron.

Keratin proteins also condition your hair well and help get rid of frizz and make them more manageable.

That’s why having a good keratin straightening shampoo and conditioner combo is VITAL for your hair care routine if you really want to have smooth, silky, and straight hair.

You can check out our Review of the Top Keratin Treatment Products for good options.

Although, overusing keratin can lead to oily, greasy, and weighed down hair. Keep this in mind if you’re thinking of using a keratin-based product.


Natural Oils

Moving on, natural oils are also widely used for hair straightening shampoo. In fact, most hair straightening shampoos in our list contain these oils.

These oils work as conditioning agents that help moisturize and smoothen your mane. A prime example of an oil that works well is coconut oil.

Coconut oil is great at locking in moisture in your follicles and makes your frizzy hair smoother and more manageable.

Having these kinds of natural ingredients isn’t a must, but they do give AMAZING effects and is generally safe for sensitive scalps and damaged hair.

That’s something to keep in mind if you experience those issues.



You probably know this one, but the Agave Healing Oil Soothing Shampoo is our way to go for the best hair straightening shampoo out of all the hair straightening shampoos on this list. What really makes this one stand out compared to the other products is its overall features:

  • It’s all-natural, which means that it’s safe for damaged hair and itchy, sensitive scalps.
  • It’s also free from sulfates, parabens, and phthalates. Safe for treated and colored hair!
  • Another thing is its key ingredient: Agave plant sugar. This is what makes this straight-shampoo unique. This ingredient makes its way deep into your hair strands and deals with all the dirt and residue that’s there. Once it coats your hair, it deeply nourishes your mane and balances the pH level of your hair and scalp.
  • It’s great and handling frizz and it’ll make your hair shinier, silkier, and more vibrant.

One other notable shampoo is the award-winning Davines Love Smoothing Shampoo. This made its way to 3 awards in the past decade. That’s an impressive resume and this shampoo does not disappoint.

  • Although, the reason why this shampoo isn’t our number one pick is because of its terrible packaging. The bottle this shampoo has is just too flimsy and low-quality. It can leak and get damaged when you have it shipped from Amazon.
  • Regardless, what makes a shampoo great is its contents, not the packaging, but we can’t really let it slide which is why the all-natural Agave option is still number one.

If a great budget option is something that suits you best, then you also can’t go wrong with the John Frieda Frizz Ease Flawlessly Straight Shampoo. This is a great keratin-solution product that can probably be suitable for any budget.

  • One of the problems this has is how greasy and oily your mane can get.
  • Keep in mind the way this product can affect your hair because it also contains sulfates. To handle these problems, a great shampoo and conditioner combo is essential.
