Asking someone with a totally different hair color to do your roots

You may have heard that you can get a friend to color your roots, but unless they have exactly the same hair color as you, it’s not really a good idea. If you’re going from dark to light or vice versa, it’s best to leave this job up to a professional—they’ve been trained in how to match your natural color and will be able to do so much more accurately than someone who just happens to have similar hair. And when it comes down to choosing the right products for coloring at home? You’ll have an easier time figuring out which ones will work best if someone with similar hair already knows those things!

Using a box-dye kit

• Box-dye kits are not necessarily the best option for everyone.
• The color on the box is not always what you get.
• Box dyes use a one-size-fits-all approach to hair coloring and don’t take into account your coloring or texture.
• Box dyes can be too dark or too light, which means you’ll end up spending more money on touchups than you would have if you’d just gone to a salon in the first place!

Not blending old and new highlights enough

One of the most common mistakes we see people make at home is not blending their old and new highlights enough. You want to make sure you’re using the correct color that matches your natural hair color, and when fading an old highlight, you want to use your natural color (not the same shade as your new highlight) to blend in between them so it looks seamless. If you don’t get this right, it can result in spots of brassy/yellow-toned color where there should be a nice golden glow. To fix this, try using a sulfate-free shampoo and conditioner like our Color Care Shampoo & Conditioner Duo from Redken or Pureology Hydrate Shampoo & Conditioner Duo for dry hair types — both of these products are designed with moisturizing ingredients that will help revitalize your locks without stripping away any moisture!

Turning red to blonde in one shot.

It’s tempting to want to go from brunette to blonde in one shot—but it’s a bad idea. If you do this, your hair will be damaged and become brassy. You need to use a series of products that gradually lift the color out of your hair.

The first step is bleaching the darkest parts of your hair until they’re white, then lightening them further with toners until they match the rest of your hair. The second step is covering all those bleached bits with semi-permanent color so they don’t look like straw anymore!

Don’t jump from medium brown hair to platinum blondee by yourself

You will need to go from dark to medium ash blonde to platinum blonde. If you try to do this with one application, you’ll end up with orange, brassy hair and your stylist will be furious with you. You will need multiple applications over the course of several weeks before going platinum—which means paying for lots of root touch ups and toners every few days. There’s also the added step of using purple shampoo every time you wash your hair to remove brassiness instead of letting it sit in your roots for months at a time.
