The skin covering your head—your scalp—not only provides the first line of defense against external aggressors, it sets the stage for healthy hair growth. 

K18’s new AirWash™ dry shampoo was formulated with your scalp in mind. Powered by K18-patented biotechnology and scalp-friendly ingredients, it maintains a healthy scalp-sebum balance, instantly reduces oil + eliminates odors for up to 3 days*, and makes hair and scalp feel healthy and fresh*.

Why are we so passionate about scalp health? Think of your scalp as the earth and your hair as a flower, you need a high-quality and nourishing environment for that flower to thrive.  A healthy scalp = healthy hair!

what creates an unhealthy scalp?

Things like oxidative stress fueled by external aggressors, such as UV rays and chemical treatments, or internal aggressors like excess sebum can disrupt scalp health. Damage from oxidative stress can be seen in the hair in the quality of the cuticle which impacts the look and the how the hair fibers feel. This negative stress can impact hair’s ability to defend itself against damage and reach its full growth potential. It may also lead to scalp conditions such as premature hair loss or graying, dandruff, and psoriasis.

Your scalp is covered in hair follicles, the tiny mini-organs that make your hair grow, and sebaceous glands, which produce sebum, an oily substance that moisturizes and protects your skin and hair. When this sebum builds up, it can create a greasy look and feel. An excessive amount of sebum can also alter the activity of the scalp microbiome. The microbes break down the sebum into free fatty acids, these are then oxidized, leading to oxidative stress.

When you forgo regular hair washes, the excess sebum and oil can act as food for bacteria. This bacteria breaks them down, potentially causing odor, discomfort, and imbalance. That’s where AirWash™ comes in.

how AirWash™ supports your scalp 

Unlike many traditional dry shampoos, AirWash™ is a scalp-friendly formula that delivers a high-performance clean without disturbing your scalp’s delicate microbiome. This allows you to extend clean hair for up to 3 days* while eliminating causes of scalp irritation like buildup, excess sebum, or heavy fragrances. But how?

AirWash™ has oil-absorbing translucent microbeads that help reduce the oils before they can cause your hair or scalp harm. It also has K18-patented odorBIND™ to trap and eliminate odors on contact and for up to 3 days*. 

AirWash™ scalp-friendly ingredients

AirWash™ dry shampoo is formulated with intentional ingredients that work together to deliver a high-performance clean that lasts, so you can go longer between washes while reducing oil without contributing additional starchy buildup or white cast.
