Our verdict

A non-aerosol dry shampoo that cuts oil, sweat and odor without a white cast, made for chemically treated hair. The bottle is small and the scent subtle, so it suits lightly oily days.

Overview

Someone stretching the time between washes gets a propellant free spray here, which refreshes the scalp and absorbs oil. K18 pairs hyaluronic and lactic acid with a subtle scent, and it suits all hair colors.

A dry shampoo that works without aerosol and leaves no white residue, even on dark hair, is the reason to buy. The limitation is the small bottle and a strong focus on chemically treated hair, with no detail on very oily scalps.

Who it's for

A gym bag or work desk that needs a quick scalp refresh between washes suits the spray. Buyers with very oily roots, or those wanting a heavy fragrance, should look elsewhere.

Pros and cons

Pros
  • Non-aerosol, no propellant
  • No white cast
  • Reduces oil and sweat
  • Suits all hair colors
Cons
  • Small bottle size
  • Needs sectioning for even use
  • Scalp tolerance data not listed

Performance notes

The spray deposits absorbing particles that soak up oil and sweat at the roots, and massaging or brushing them in spreads the effect. Holding the bottle away from the scalp prevents concentrated patches that would otherwise look chalky.
