Straightening shampoo might look like a regular shampoo, but they have specially formulated ingredients like silicone, keratin also some natural oils—coconut oil, argan oil, etc.
They form a moisture-locking coating around the hair shaft. This not only blocks the moisture within the hair but also refuses any moisture to penetrate the hair cuticle, which is responsible for the frizziness.
Because of this, the ironing process is done much faster, and the effect lasts longer. Faster flat-ironing also means less exposure to heat and damage. These shampoo ingredients also help loosen the curls and make them appear straighter and more manageable.
Take a small note on these 3 points mentioned below. They will help you choose the ideal one for your need.
- Presence of Keratin: Keratin is the building block of your hair. Shampoos that contain keratin protects the hair from heat damage. It heals the hair cuticles also restores the moisture. They are absorbed by the hair and loosens the natural curls making the hair appear smoother and frizz-free.
- Silicons: Silicons form a waterproof coating around the hair which locks the moisture in and don’t let the hair absorb the outside humidity. So, it holds the hairstyles for a longer time.
- Sulfate-free shampoo: Sulphates, mainly Sodium Lauryl Sulfate and Sodium Laureth Sulfate, are hugely used in shampoos, which makes the lather. If you have color-treated hair or have keratin/Brazilian hair treatment done, you strictly need to stay away from sulfates.

Things to consider before buying a straightening shampoo
Straightening shampoos have a different list of ingredients. To protect your hair from the burning heat of a flat iron or to extend the life of your chemical treatment, they include highly hydrating ingredients.
They block the moisture in, restores the hair proteins and form a glossy smooth coating around the hair shaft. Then some straightening shampoos are better than the other. And some are more suitable for your colored hair, and some are better for your dry-damaged hair.
Below we have a list of 5 things that you need to consider to get the most out of your straightening shampoo.
1. Keratin proteins are excellent
If you have undergone any chemical hair processing, straitening, smoothing, Brazilian or keratin treatment, you must look for ‘keratin’ in your shampoo.
You have heard the term “keratin” a gazillion times, but what is it? There is a lot of misconceptions about the name. Keratin is actually a protein found in hair, nails, and cuticles. It is the building block of your hair.
The protein keratin is a protective protein. This means it is tough and less prone to breakage and damage. When used in shampoo, the outer layer cells of your hair absorb the protein. So, when you style your hair with heat, it protects it from damage and breakage. It makes them stronger and fuller.
Keratin is also great at nourishing your hair. When absorbed by the hair cuticles, it makes it appear smoother and less frizzy. You will notice your hair looks a lot straighter, healthier, and shinier.
2. Look for silicons
Silicone is the most important ingredient in a straightening shampoo. It is a polymer with hydrophobic properties (waterproof). They form a thin waterproof layer around the hair fibers, which is impenetrable for moisture.
Silicons not only lock the needed moisture within the hair shaft but also refuses the humidity to penetrate the hair, which causes frizz. As a result, the hair could hold the styles for a much longer time. The thick, glossy layer of silicons also leaves your hair smoother, softer, and shinier.
Silicons have with ‘cone ‘, ‘conol’, ‘xane’ at the end of their names. Some common silicons found in straightening shampoos are-
Note: Are silicons bad for hair? Silicons do have a bad reputation. This is because they weigh the hair down. Especially the thin and oily hair types. They can produce more build-up and makes you wash your hair more often.
But it is not harmful to your hair. They are non-toxic and made for human use. Celebrity hairstylist John Freda says silicons are essential in a hair straightening shampoo. They have amazing hydrating properties; they hold the style for longer and resistant to humidity, which is the main reason behind frizzy hair.
3. Sulfate-free straightening shampoo
Sodium Lauryl Sulfate and Sodium Laureth Sulfate is also known as SLS/SLES, are two potent ingredients that make the lather. They are not good for color-treated hair. They wash off the color within 1 to 2 weeks.
SLS and SLES are also not good for chemically treated hair (smoothing, Brazilian/keratin treatment). They will wash off the keratin layer and will strip off the moisture.
4. Natural oils
You can find many types of natural oils in a straightening shampoo. They have incredibly moisturizing and hydrating properties. They make the hair healthier from within. And prepares the hair for styling experiments. Some of them are-
- Coconut oil-the vitamins and fatty acids deeply nourish the hair and reduce frizz
- Almond oil-reduce the chances of breakage and split ends
- Argan oil-antioxidants, fatty acids, and Vit E improves elasticity and deeply nourishes
- Cocoa butter- hydrates and make hair smooth and soft
- Castor oil-protects the hair follicles
- Glycerine-intense moisturizing properties
5. Volume of the bottle
You might not want to use a straightening shampoo every day. In alternative days you can use a hydrating shampoo or a clarifying shampoo to restore the moisture and remove all the build-up. So, buy a smaller pack of shampoo. Also, remember that if you buy a sulfate-free shampoo, you will need more of it. Because it makes less lather. And it will run out faster.
Straitening shampoos are lifesavers for frizzy and unruly hair. They make it more manageable, smooth, relaxed, and looses up some curls. But, note that they can’t change your hair texture. Even the best out of the best straightening shampoos won’t be able to make it super silky and straight. It’s only possible with a chemical treatment.
If you are confused about your first purchase, our first recommendation would be John Frieda Frizz Ease Flawlessly Straight Shampoo. Its excellent at holding the style protects it from heat damage. It also has the must-have hair protein keratin. Above, all it’s in the budget. However, if you have keratin-treated hair go with OGX Ever-Straightening + Brazilian Keratin Therapy Shampoo.
