Should You Dye Your Hair? A Few Tips

I’m sure you’re inspired to follow in your fave idol’s footsteps and dye your hair an interesting color! But, before you get into dying your hair, you might want to take note of the following:

Tip #1: Find a color that matches your skin tone

First, you need to determine your skin undertone. Hold up silver and gold jewelry to your skin. If you look better with gold, you have warm undertones. Otherwise, if you look better with silver, you have cool undertones.

The rule of thumb is to pick colors opposite of your skin’s undertones on the color wheel. For more information, check out this video on how to find the right color for your skin tone

Tip #2: Do your research

Before committing yourself to a color, try to learn more about what you’re getting into first. Would your desired color need bleaching? What kind of treatments do you need to do after you’ve colored your hair? What products do you need to keep your hair and color healthy?

Some colors like platinum blondes or pastels are more high-maintenance. Others, like balayages or dark neutrals are easier to maintain. There’s a lot that goes into coloring your hair, so make sure you’re ready for it!

Tip #3: Choose a high quality dye

Hair DyeIt’s best to choose hair dyes that don’t contain ammonia or other harmful chemicals. Always make sure to use a dye that won’t trigger any allergic reactions. Idols often use dyes from Mise En Scene, Etude and Somang Clinic.

Try to avoid box dyes too, as they don’t always deliver on the colors you want (plus they’re really damaging).

It’s no secret that dyeing your hair is damaging, especially if you intend to do it frequently. Bleaching is one of the harshest ways to dye your hair. But, it’s also a necessary procedure if you want to achieve bright colors like reds, blues and others.

Be ready to look for products to keep your hair healthy and moisturized after dying or bleaching. We recommend trying the Olaplex line, which is a favorite among Korean stylists!

Tip #5: Prepare your budget

Prepare your budgetDyeing your hair can get really expensive, so make sure you can prepare the budget for it. Apart from the coloring, you need to shell out money for maintenance and treatments. You’ll also need to invest in regular touch-ups or salon visits to keep your color vibrant.

Tip #6: Consult a professional

Consult a professional
