Can You Use Dry Shampoo on Keratin-Treated Hair? Expert Tips

Dry shampoo has become a holy grail in the hair industry. Many women swear by its ability to give hair volume and texture without weighing down their hair or leaving them smelling funky.

Some even claim that they get away with skipping washing their hair altogether. But can you use dry shampoo on keratin-treated hair?

Let’s find out.

Key Takeaways

  • Sulfate-free dry shampoo can be safely used on keratin-treated hair without causing damage or interference.
  • Using dry shampoo reduces the traditional shampooing frequency, helping to maintain and prolong keratin treatment effects.
  • Apply dry shampoo sparingly, focusing on roots, and gently distribute the product for best results on keratin-treated hair.

How to Care for Your Hair After a Keratin Treatment

Keratin hair treatments are not permanent, so you need to take care of your hair after the treatment [1].

To keep your hair smooth, healthy, and shiny for a long period of time, it is important to avoid washing it too frequently. Do not get your hair wet for at least 72 hours. Washing hair less often means that the effects of shampoo won’t wash off quickly.

You should also avoid exposing your hair to harsh elements such as chlorine, sodium Laureth sulfate, sodium lauryl sulfate, and saltwater. These elements can damage your hair and make it lose its shine. And even cause hair breakage.

Avoid overuse of styling products like mousse, gels, and hair sprays. These tend to cling onto hair strands and leave a residue.

Do not use salt-based shampoos. These shampoos will dissolve the keratin coating, and your treatment will not last.

Hair experts suggest avoiding shampoos with alcohol as they can dangerously dry up the hair.

If your hair becomes dirty or greasy after your treatment, then you might consider using a dry shampoo to lightly freshen it up.

Dry shampoos are made from ingredients like cornstarch, denatured alcohol, talc, and other substances [2]. 

They work well because they absorb oil and dirt while keeping moisture in your hair. This prevents your hair from becoming oily and keeps it looking clean.

When you spray the shampoo onto your scalp, the alcohol or starch absorbs oils and grime, leaving your hair clean without weighing down your strands.[3]

Dry shampoo is best used as a temporary fix — not a replacement for regular washing. Use it sparingly as a means to freshen up your hair and not necessarily to clean it.

Some really great keratin dry shampoos include keratin complex, Lasio Dry Shampoo, Batiste Dry Shampoo, and Klorane dry shampoo.

While using dry shampoo on keratin-treated hair can help maintain your style between washes, you might also be curious about how to add more volume to your hair.

Before you start spraying the shampoo, shake the container to ensure the formulation is evenly distributed. This will, in turn, result in even distribution on your hair.

For proper application, part of your hair into sections. Working from the top down, starting with the greasiest sections.

  • Hold the bottle 6 inches away from your head and spray just enough to cover the roots of your hair. Avoid spraying too close to your scalp so that you don’t get residue that’s hard to eliminate.
  • Then rub your hands together and gently work the product into your hair. Massage the product into the scalp with fingertips. It’s vital to let the product sit for a couple of minutes for it to work its magic.
  • You should feel the powdery texture of the dry shampoo against your skin.
  • When finished, brush your hair until the powder disappears.

How To Choose The Right Dry Shampoo

Dry shampoo comes in many different varieties, from foam and powders to sprays. 

Choosing the right shampoo for keratin-treated hair will significantly affect the desired results. 

If you have fine hair, a powder formula will most likely be heavy on your strands. It’s advisable to go for an aerosol instead.

You should a dry shampoo depending on your hair color. If you have dark hair, ensure you choose one that can absorb oil and has an invisible formula to avoid white residue.

Choose a waterless formula depending on your hair needs. If your hair is extra greasy and needs a deep clean, you need a product that is super absorbent. 

Choosing the right dry shampoo isn’t always easy. There are many different brands available on the market today, each claiming to be better than the rest. But with the right tips, you will be able to choose the perfect dry shampoo.

 Dry shampoo is not meant to replace real shampoo, and you should not use it regularly.

Regular use of dry shampoo will result in product build-up on the scalp, clogging the hair follicles and eventually preventing cell turnover. [4]

The build-up can also result in an overgrowth of bacteria and yeast growth.
