Coloring blond hair is a perfect way to change your look. However, if you are unhappy with the end result, permanent hair color will stay until it is cut out of your hair or re-colored. Significant research links the regular use of hair dye to cancers such as non-Hodgkin's lymphoma (cmrsnews.com). Using coffee to dye blond hair is a natural and inexpensive coloring alternative. Furthermore, because it is a temporary hair color, it will wash away after several weeks.
Brew coffee at triple strength. This means you will brew 3 tbsp. coffee to 1 cup water. Make at least 6 cup servings at this strength. Allow the coffee to cool completely.
Wash your hair with shampoo and rinse thoroughly.
Place a large bowl or bucket into a sink or bathtub.
Rinse your hair with cooled coffee. Collect excess coffee in the bowl or bucket that you have placed into the sink or tub.
Place a second empty bowl or bucket into tub. Remove the first bowl and repeat the rinse procedure.
Repeat the rinsing process at least five more times, collecting excess coffee in an empty bowl after each rinsing. The more you rinse your hair with the coffee, the darker the end result.
Allow your hair to sit after the last rinsing for at least 20 minutes. The longer you let your hair sit, the darker it will become.
Wash your hair again, using a mild shampoo. Dry with a towel.
Style hair as desired.
Do not put a towel over coffee-saturated hair, as the towel will absorb the coffee. Put your hair in a clip on top of your head to keep it from dripping. Coffee is not a permanent hair color; it will eventually rinse out after repeated washings. To protect clothing, use a hairdresser's cape.
Do not wear light or white clothing immediately after dying your hair, if you have long hair. Coffee can rub off your hair and permanently stain your clothing. Do not walk around with coffee-saturated hair. The coffee will leave permanent stains on anything on which it drips.
