5 Correct Mistakes
If you accidentally leave the color in too long or it turns out to be too dark or concentrated, you can try wash your hair out with dishwashing soap two to three times to lighten color. Use it like shampoo and rinse out completely.
4 Make the Color Last
After you’ve followed all the instructions on the box exactly, rinse out the color with cool water instead of hot so that the color lasts longer. If your kit contains a conditioner, use that, otherwise, apply another type conditioner, preferably one that’s meant for color-treated hair. You could also use a leave-in conditioner. Just make sure you wear a hat when you’re in the sun for a long time and avoid over-styling with curlers and straighteners to keep the hair healthy and the color bright.
3 Create an At-home Salon
This can be a messy process, so you’ll need to set up an area you don’t mind if dye gets dropped. Lay down a drop cloth or old sheet or towel on the ground and cover the countertop with newspaper. You’ll also want to wear an old T-shirt or smock in case you drip on your clothing. Remember to apply petroleum jelly or moisturizer along your hairline so the dye doesn’t spread onto your forehead.
2 Pick the Right Dye
When deciding what color to dye your hair, most stylists recommend only going two shades darker or lighter than your natural hair color. Because at-home dyes are pre-mixed, they’re not as tailor-made as dyes mixed in the salon and can turn out differently than you expect. You should also stick to softer colors as opposed to bright, edgy colors to ensure the color doesn’t turn brassy. Lastly, to choose between permanent and semi-permanent, decide whether you want a subtle or dramatic change. Semi-permanent is more subtle and washes out within 20 washes. Permanent is more dramatic and is better for covering grays.
1 Prepare with a Conditioner
Two weeks before you plan on coloring your hair, prep your hair with a deep conditioning treatment to help you hair keep the color better. Or if you decision is a bit more spur-of-the-moment, try a hydrating mask one day prior. The more moisturized each strand is, the healthier it is and more ready to hold the color. Don’t worry about washing your hair right before the coloring, though, the dye will penetrate through the natural oils and hair products.
