Kim Kardashian may be an open book, but if there's anything she's never revealed, it's the secret to how she achieves her hair color. Well, it's finally out!

On Sunday's episode of Keeping Up With the Kardashians, the mother of three confirmed that she dyes her hair to achieve the platinum silvery-white color.

In a quick clip, Kim is on the phone with her mother, Kris Jenner. When Jenner asks if she can come over for a meeting, Kim explains that she can't because she is dyeing her hair.

The 37-year-old further elaborates that she is coloring her hair blonde and it is going to take "forever" to do it. Kris jokingly replies and asks her if she has ever heard of a wig.

"I don't like wigs. They're just not for me," Kim says.

Khloe Kardashian, who is also in the room, shakes her head and rolls her eyes over the conversation.

Kim Goes Blonde

The self-proclaimed selfie queen debuted her new platinum silver locks during New York Fashion Week in September 2017.

When asked why she decided to go blonde, Kim stated that she has been talking about going blonde for some time now and she wanted a whole new vibe.

The makeup mogul also revealed that she was not wearing a wig. She actually colored her own hair.

"I know a lot of people initially thought I was wearing a wig, but it's my real hair," Kim said.

The Process

For those wondering who the mastermind is behind the iconic color, it's none other than celebrity hairstylist Chris Appleton.

Appleton is responsible for several celebrity looks such as Jennifer Lopez, Ariana Grande, and Shay Mitchell.

While Appleton has received praise for Kim's loose waves and platinum hair, fans will be surprised to know that it took him over 15 hours and an additional 5-hour session to achieve the look.

Since Kim has been wearing the color for some time now, she has stated that the transition from her usual dark hues to light was well worth the process. 

Although the color may have worked out for Kim, this isn't the first time she attempted the color. In 2015, the Keeping Up With the Kardashians star experimented with the Madonna-inspired shade, but she explained that it didn't work out because she didn't give it the proper time to develop.

This time, Kim made sure to keep a low profile with yellow hair, before debuting the new look.
