It takes 45 minutes to bleach my hair including set time and rinse. Then about 2 hours for Addie to apply the various color dyes. (she is picky and takes her time) Then about 45 minutes for dye to set. And finally about 10 minutes to rinse and wash. After about 3 days the dye stain comes off the scalp and just the hair is colored. In all its about 4 hours to create. We cut my hair prior to dying it so that took some time also. So if you plan on doing it too then be sure to set aside at least 5 hours 🙂
