It’s a tale as old as hair color: Many years, dozens of touch-up appointments, several rounds of Olaplex, and you’ve finally made the decision to go back to your natural hair color. Not that the latest trendy shade of blonde hasn’t been fun, but at a certain point the expense and damage gets old, especially when your hair is naturally dark brown or black.
But before you call your colorist and drop the big news, there are a few things to prepare yourself for ahead of the appointment. After years of pledging your allegiance to peroxide — whether it’s just highlights or a full bleach-and-tone — you’ve probably forgotten about the treatments that make brunette hair shine the brightest, from gloss touch-ups to at-home remedies. Don’t stress, we tapped the pros to answer all your burning brunette questions before you ditch your blonde hair for good, ahead.
There’s A Right & Wrong Time To Go Brunette, But It’s Not Seasonal
There’s a myth floating around that changing your hair should follow the changing seasons. For example, it’s best to blonder in the summer and darker in the winter. However, most colorists will agree that this is an outdated motto. "When you’re ready, you’re ready," says Olivia Casanova, colorist at IGK SoHo salon.
But that’s not to say timing isn’t important. Nikki Lee, a seasoned colorist and co-owner of L.A.’s Nine Zero One salon, tells her clients to avoid any tropical trips after your dye job. She stresses that going from blonde to brunette can take several appointments, and exposing your newly dyed hair to the sun or ocean water could potentially affect its vibrancy.
"Filling The Color" Is Crucial
Going brunette will typically consists of three or more steps, says Casanova, each of which could take anywhere from 10 to 40 minutes. The first step? Fill the hair. "Filling" means restoring the warm pigments that were lost during the lifting and bleaching process. Similar to the many steps it takes to lighten hair, it takes work to layer color back in. The filling process does that, but in reverse — redepositing the underlying warm shades that naturally exist beneath brown hair colors, explains Jeremy Tardo, colorist at Benjamin Salon. This way, your new brunette shade can fully saturate every last strand of hair without awkwardly fading.
We know what you’re thinking: So, I can’t just color my hair a dark brown and move on with my life!? Unfortunately, your hair is most likely in an unhealthy state after undergoing lightening, which determines how easily the new, darker color is absorbed. Lee explains that when hair is bleached over and over again, it’s difficult for any color to truly stick. Lee explains that if you are as icy-white as Daenerys Targaryen, then your new brunette color could settle in very dark or end up muddy. This all depends on how porous your hair is from the bleaching process. “It’s important to layer color on top of color until you reach your desired look,” Lee says. “Start lighter and go deeper as you dye."
It’s Good To Know Your Color Lingo
Do you prefer demi-permanent, semi-permanent, or permanent color? Don’t worry, we’ll help you figure it out. Only after filling the hair can you reach the desired shade, which is often created with a semi-permanent or demi-permanent dye. Some colorists, like Lee, recommend a semi-permanent dye for the first appointment), while others, like Casanova, opt for demi-permanent formulas. What’s the difference? Semi-permanent can only hold up to about six shampoos, but tends to fade without any harsh lines. Demi-permanent dye, on the other hand, can maintain its shiny color for over 20 washes.
In short, these two options let you feel out your new color with minimal commitment. You can always go back into the salon and request permanent dye later, but few colorists will start you with it. "I personally never use permanent color to take someone from blonde to brunette," Tardo explains. "Permanent color is necessary only for gray coverage or for lightening without bleach."
Your Hair Might Turn Green — But Don’t Freak Yet
Although going natural means less worry about discoloration down the road, you’re not out of the woods until all that processed hair grows out and gets chopped off. In fact, now you have to worry about your hair turning green. This usually happens if you go too cool in tone, as opposed to a shade with warmer undertones on the first go around. If the base color isn’t warm enough, the new brunette color can fade to a muddy brown or green.
Keep in mind that your hair can always change color. "There are so many determining factors," Casanova says. The solution: Popping into the salon for a toner retouch is quick, easy, and makes a huge difference in keeping your color rich.
Getting Lowlights Is Helpful
Going from a bleach blonde to a solid brunette is a drastic change that sometimes feels too shocking, so Lee reminds us that blonde highlights are always an option. “These are my favorite transitions because the color ends up having a beautiful brunette dimension,” says Lee. It’ll take a few appointments to nail, but it’ll also help you blur any lines of demarcation.
For Tardo, it includes leaving out some of the existing blonde hair, dyeing the rest brunette, and toning the remaining blonde pieces with a color a touch lighter than the brunette base. Want to make an even slower transition to brunette? Jenna Perry, lead colorist at New York’s boutique salon White Rose Collective, suggests shading the root down and adding lowlights before returning to one solid shade.
Look Into At-Home Treatments Made For Brunettes
Yes, even bottle brunettes can go brassy, which is why Lee recommends her brunette clients to still use a purple shampoo when they notice unwanted undertones surfacing. Her favorite: Mr. Smith Purple Shampoo. If brassiness isn’t a concern for you, Perry suggests ditching the purple ‘poos and conditioners for color-depositing treatments, like Davines’ Alchemic conditioners that come in a variety of shades, like chocolate, copper, and tobacco.
Color-safe shampoos are a must, especially formulas that are sulfate-free. These will ensure your straight-out-the-salon shine lasts weeks longer than it might if you opt for harsher cleansers with sulfates. Tardo adds that when it comes to styling products, make sure to use conditioning, leave-in sprays that will boost your hair color and protect against the elements with UV filters. Lastly, look for products, like IGK Bad & Bougie Repair Shampoo, that include a bond-building technology. It won’t just strengthen hair immediately, but it will slowly repair the damage left behind from your former blonde moment. And speaking of bond-building technology, you may think being a brunette frees you of your Olaplex dependency (and saves you several Sundays of pre-shampoo conditioning treatments), but alas, Perry confirms brunettes need it just as much as blondes. It might take some work, but it’ll be worth it. Welcome to the dark side.
