Dry shampoo is a gift that keeps on giving. It is convenient and saves us the time that we spend doing the lengthy ritual of hair wash, especially when there is a time crunch. Dry shampoo has become a staple in many people's beauty routines as it offers a quick and convenient way to refresh hair between washes. But how does this magical product work, and what are its benefits and drawbacks?

How does dry shampoo work?

Dry shampoo works by absorbing excess oil and sebum from the scalp and hair, leaving strands looking and feeling refreshed. Most dry shampoos contain powdery or absorbent ingredients such as starches, clays, or silica that help soak up oil and dirt without the need for water. When sprayed or applied to the roots and oily areas of the hair, the dry shampoo particles bind to the oil and dirt, effectively lifting them away and leaving hair looking cleaner and more voluminous.

Benefits of dry shampoo

Dry shampoo is a quick and convenient solution for refreshing hair between washes, saving time and effort on days when washing and styling your hair is not practical.

In addition to absorbing oil, dry shampoo can add volume and texture to limp or flat hair, making it ideal for styling and creating effortless, lived-in looks.


Dry shampoo can help extend the life of hairstyles, particularly for those with oily hair or fine strands that tend to lose their shape quickly.

Dry shampoo is compact and portable, making it perfect for travel or on-the-go touch-ups when access to water and traditional shampoo is limited.


For those with coloured or treated hair, using dry shampoo between washes can help prolong the vibrancy of hair colour by reducing the frequency of washing.

Drawbacks of dry shampoo

Using dry shampoo too frequently or applying too much product can lead to a build-up of residue on the scalp and hair, potentially causing irritation or clogging hair follicles.


While dry shampoo can temporarily refresh hair and absorb oil, it is not a substitute for regular shampooing and cleansing, which is essential for maintaining scalp health and removing product build-up.

Some dry shampoos contain alcohol or drying agents that can strip the hair of its natural oils, leading to dryness, breakage, and dullness over time.
While dry shampoo can help absorb moderate oiliness, it may not be as effective on very oily or greasy hair, requiring more frequent washing for optimal cleanliness.

How to use dry shampoo

Shake the bottle well before use to ensure proper distribution of the product.

Hold the bottle 6-8 inches away from the scalp and spray evenly onto oily areas.

Allow the dry shampoo to sit for a few minutes to absorb oil, then massage or brush through hair to distribute the product evenly.

Use sparingly and avoid applying too much product to prevent residue build-up.
