Dying half your hair leaves the wearer with a unique look that can be dramatic or subtle. Pick a high contrasting color to pump up the drama. Dying your hair at home is a fairly simple process. Dying half your hair is actually easier than dying all your hair because there is less color to apply. Learning this simple technique gives you the tools to create your own unique hairstyle without salon prices.
Decide how you want to dye your hair: top and bottom, or side and side. Use a comb to create a part on the dividing line. Use a mirror to check and see if the part is straight. If you have problems determining if the line is straight, ask a friend for help.
Clip up the half of your hair that you're not going to dye. Pile the hair on top of your head. Make sure its not hanging down in the way of the other half.
Mix the hair dye and developer according to the instructions on the box. Shake it well and remove the cap. Put on latex gloves. Most hair dye comes with gloves.
Separate the hair you are dying into small sections. Work from top to bottom. Apply the dye to the root first and then up to the tip. Make sure each section of hair is saturated with dye. Continue until the entire half is covered in hair dye.
Let the dye sit on your hair as long as the box instructs. When it is finished, get in the shower and turn on the water. Try to hold your head so the dye does not run onto the half of your hair that you don't want to color. Rinse your hair until you stop seeing dye in the running water.
Remove the clips from your hair, and apply a deep conditioner to your entire head of hair. Let it sit for two to three minutes. Rinse out the conditioner. Get out of the shower, towel dry your hair and blow dry if you desire.
