For using coffee to darken hair or cover grays, strong coffee, such as espresso, is best.
The key to using coffee as a hair treatment lies in its ability to stain the hair shaft, providing a temporary color boost and covering gray hairs. The darker and more concentrated the coffee, the more effective it will be.
Here's why espresso is preferred and how to maximize its benefits:
-
Concentration: Espresso is a highly concentrated form of coffee, packing a stronger pigment punch compared to regular brewed coffee. This is crucial for achieving noticeable color changes.
-
Darkening Effect: The dark color of espresso helps to stain the hair, masking gray strands, and enhancing the overall darkness of brown or black hair.
-
Application: After brewing a strong espresso, allow it to cool completely. Apply it to clean, damp hair, ensuring thorough coverage, especially on gray areas. Leave it on for at least 20-30 minutes before rinsing with cool water.
-
Frequency: Repeat the coffee rinse regularly (e.g., once a week) to maintain the desired color and coverage.
-
Additional Tips: Combine the cooled espresso with coffee grounds to make a paste, apply to gray areas, and let sit to help to better target coverage of gray hairs.
While espresso is recommended for its strength, other dark roasts, brewed very strongly, can also be used. The most important factor is the concentration of the coffee.
