Dying hair from red to pink is a dramatic change. Hair dye is a permanent color applied to the hair. It can be applied to the whole head or in small sections. When dying hair from dark to light, you will need to use hair bleach to create a clean palette to which the pink dye can adhere. Bleaching is a crucial step because the hair ends up discolored if you skip it. Fortunately, dying your hair from red to pink is fairly simple.
With a comb, separate the section of hair you want to dye with a comb. Paint it from root to tip with hair bleach. Make sure to apply an ample amount to the roots as well as to the tips. The tips of the hair are dry and it is more difficult for them to absorb dye. Wrap the piece in foil to separate it from the rest of the head. Repeat this until all your hair is wrapped.
Allow the bleach to sit for the amount of time prescribed on the box label. Most bleach needs to sit from 15 to 25 minutes.
Remove the foil and rinse your hair off in the shower. Apply a deep conditioner and wait for 2 to 3 minutes. Rinse out the conditioner. Wait for your hair to dry, or blow dry the hair.
Separate a bleached section of your hair and paint it from root to tip with the pink hair dye. Follow the same procedure as Step 1. Wrap the hair in tin foil. Repeat until all the bleached hair is dyed and wrapped.
Wait for the hair dye to develop. Read the dye instructions for the appropriate wait time.
Remove the foil. Rinse your hair in the shower until you stop seeing dye running into the tub. Apply the deep conditioner and let it sit for 2 to 3 minutes. Rinse the conditioner out.
