According to Good Housekeeping, it is possible and easy to dye your hair yourself. Good Housekeeping stresses that more than two or three shades from the current hair color should be left to professionals, many people color their hair at home every day. Also make sure before you begin dyeing your hair your plumbing works. I had a broken pipe when I started mine and I couldn’t rinse my hair.
The key to dyeing your hair by yourself is to be prepared. If your hair is shoulder-length or greater, buy two turquoise color kits. Having multiple pairs of latex gloves, a coloring comb, a shower cap, and a bowl and brush for the dye, like professionals use, will make the process easier and the result will look more professional. Go through the kit boxes and lay out everything before starting, like a dentist or surgeon. Read all of the instructions beforehand and be sure you understand the process, to avoid stopping in the middle and possibly leaving the dye in for too long, which is a very common mistake. Have solid, clear lip balm to apply along your hairline to avoid dye streaks on your forehead, and make sure to have makeup removing towelettes available to clean drips and streaks off your skin as soon as they happen to avoid staining.
Make sure the area is prepared. Put down newspapers to protect the floor from dripping dye. Wear an old robe or open front top to avoid messing up the dyeing process by pulling a top over your head when you rinse. Make sure you have at least two mirrors set up so that you can see what you’re doing and apply the turquoise dye evenly. Start at the top of your head to allow the roots to process longest and comb the dye evenly through your hair. When it’s time for the dye to process, make sure to use a shower cap so you can move around without splattering dye throughout your space.
