If you’re thinking about bleaching your hair so the color shows up better, purchase their bleach kit as well. [2] X Research source Choose a Classic or Amplified dye from your local beauty store or online.
Before you start, protect the surface under you. Lay down newspaper or plastic bags, that way you don’t stain your furniture. The kit comes with plastic gloves, bleach powder, developer, a plastic container for mixing, a tint brush, and a plastic cap. How long to leave the bleach in will depend on the natural color of your hair, so check it every ten minutes to see how light your hair has gotten. Wash your hair several times using shampoo if you bleach it to make sure all of the bleach is out of your hair. Bleaching your hair beforehand is especially important if you’re dyeing it a pastel shade.
Don’t use conditioner on your hair beforehand, as this will prevent the dye from adhering to your hair correctly.
Once you’re completely done with the dye process, the petroleum jelly will wash right off.
The test section only needs to be about 0. 5–1 in (1. 3–2. 5 cm) in width. While it’s not required that you do a test strip, it’s a good way to know for sure how the dye will affect your hair before applying it to your whole head. Do a patch test using the hair dye by spreading a dot of it on your skin to make sure you’re not allergic to it.
Sometimes a hair dye kit will come with plastic gloves, so check the box before purchasing an extra pair.
Consider separating your hair into sections to make it more manageable to dye, if desired. Short hair will likely use about half of a jar of dye, while longer hair will need a full jar.
If you’re not noticing the dye become frothy, apply additional coats onto your hair.
If your hair doesn’t absorb dye well, leave the dye in for at least an hour. Set a timer so you know how long you’ve had the dye in your hair. Some people rinse the dye out after 30 minutes, while others leave the dye in for hours. Check your hair color after 30 minutes to see if you’d like to keep it in longer.
Only use the blow dryer for part of the processing time, not the entire 30 minutes to an hour.
Use a stainless-steel sink if possible to avoid stains from certain dye colors. Rinse your hair until the water is clear or only a slight tint of your color comes out. Consider rinsing your hair with water and vinegar to help the dye last longer.
To keep your new hair color looking vibrant, avoid clarifying shampoos or washing your hair too much, as well as chlorine, saltwater, or lots of exposure to sunlight.
