Can You Use Dry Shampoo on Keratin-Treated Hair?

The straightforward answer to this question is YES. If your hair has been keratin-treated, you can still use dry shampoo.

However, you need to understand what keratin treatment/Brazilian blowout is, what dry shampoo is, and if you really want to use it on your hair.

What Is Keratin Treatment?

Human hair is made of protein keratin which often gets damaged because of exposure to UV light and other environmental conditions.

However, this should not worry you because Keratin treatment reverses this effect leaving your hair looking fabulous again. Keratin treatment replenishes protein back to your hair which aids in rebuilding damaged hair parts and smoothening the cuticles, thus renewing the shine and eliminating frizz.

This process is a chemical procedure performed in a hair salon by professional hairstylists. Your hair must first be washed, after which the stylist applies the keratin treatment onto the wet hair using a brush. The hair then sits for 30 minutes to let the treatment settle.

That said, some other stylists apply the treatment to washed, blow-dried hair.  After applying, the stylist partitions the hair into smaller sections and flat iron one after another to seal the treatment.

This treatment is a semi-permanent solution and can last for 2-6 months, depending on how careful you are with your hair. The place of residence also matters because of the varying temperatures and humidity.

What do keratin treatment products do to your hair? 

Keratin treatment products are best at removing hair frizz, making your hair look healthier, and also improving its shine and color. While some keratin treatment products straighten your hair, others just relax it and loosen the curly shapes.

Think of the treatment as a topcoat for your hair. Usually, your hair will get frizzes if the cuticle, outermost layer lifts. When the cuticle lifts, various environmental factors such as moisture seep in hence swelling the individual hair shaft.

What is Dry Shampoo?

With every passing decade, a new hair product hits the market, promising to be incredibly effective in changing people’s lives for the better. Dry shampoo is one such product. They are considered by both women and men to be effective products for their hair.

Dry shampoo – effective cleaning for the first days of keratin-treated hair.

This is a fast-drying spray or a powder that provides a waterless option for cleaning your hair. Dry shampoos come in paste form while others come in various shades; hence you can match the best color for your hair.

The shampoos work by absorbing excess oils and sebum from the roots of your hair. This freshens up individual strands of your hair and leaves your hair clean with a  sweet-fresh fragrance. 

Why should you use dry shampoo on keratin-treated hair? 

Care and maintenance after keratin treatment for hair require a lot of effort. The worst part is the early stages, when your hair becomes sticky and smells bad, but you can’t wash it off. During this period, dry shampoo is a lifesaver.

When applying keratin treatment to your hair, you should avoid frequent shampooing, especially during the first from 3 to 4 days after this treatment, to ensure the treatment lasts longer. But this can make you feel uncomfortable. Oily hair, dirt, excess oil, unpleasant odors, etc. these factors will drive you crazy.

The solution to this is to use dry shampoo between regular hair washes to ensure you always have perfect and fresh hair.

With a reasonable frequency of use, two or three times per week, dry shampoo will help you maintain hair that is not only beautiful but also healthy.

However, like choosing other care products, when choosing a dry shampoo for keratin-treated hair, it is important to choose products with suitable ingredients and good for keratin-treated hair. 

Tips For Choosing Dry Shampoo on Keratin-Treated Hair 

  • A good dry shampoo for keratin-treated hair should not contain sulfate and salt components
  • No silicon components
  • Should not contain alcohol or butane components as they can dry the hair
  • Should not leave residues after use

Like any other hair product, it is imperative to read and understand the instructions before using it.

It is only when you do this that you realize if the product is suitable for your type of hair and if it would serve the purpose. For example, if you have curly hair, you need a dry shampoo with moisturizing elements. On the other hand, if you have an oily scalp, you need a dry shampoo that contains super absorbent. 

For keratin-treated hair, you should avoid shampoos containing sulfate and salt components

Salt components make your hair dry and frizzy. In addition, it will also absorb the essential oils of the scalp and make the hair more brittle due to the loss of the horny layer. 

Sulfate has the ability to dissolve and wash away keratin from treated hair. Dry shampoos contain sulfates that can remove keratin and damage your treated hair.

In the long run, this will make your hair weaker and the scalp sensitive, and easily irritated. In other words, it is advisable to use organic hair products made from natural ingredients because they will not strip the keratin coatings from your hair. That’s why you should go for a starch-based dry shampoo that is sulfate-free.

Keratin treatment helps strengthen your hair, but at the same time, the keratin coating can really give a very brittle and cozy feel which makes you feel uncomfortable. Therefore, it is essential to constantly hydrate your hair to make them more elastic and healthy. Hydration increases the keratin lifespan.

When shopping around for the best dry shampoo for your keratin-treated hair, I prefer starch-based dry shampoos to clay-based ones since they are lighter and leave less residue build-up.

Dry shampoo has a myriad of benefits for keratin-treated hair; nonetheless, overusing it can bring about problems you didn’t anticipate. Overusing it may lead to a build-up of residue on your scalp, limited hair growth due to clogged hair follicles.

The ingredients of dry shampoo will greatly affect the health of your keratin-treated hair.

The use of dry shampoo is only a solution to help you prolong the normal washing time, not a replacement for normal washing. Therefore, it is recommended that you should use dry shampoo just two to three times between hair washes.
