Kat Dennings Tried This Pinterest Hair Hack… and Failed Miserably

1. You'll Save So Much Time And Money

Coloring your grays can turn into a lifetime commitment of keeping up with the color. You’ll save time and so much money by not going to the salon every other month — and eventually every month — by letting your hair go gray. It’s freeing!

2. You'll Feel More Natural

In an interview, Macdowell said she felt "more real and honest" going gray. Gray hair is just a natural part of aging and can look stunning when cared for with regular cuts and gentle styling, giving you a unique look that actually makes a positive statement.

3. You'll Look More Confident

Embracing your gray hair can boost your confidence, showing the world that you're comfortable in your own skin.

4. You'll Reduce Your Exposure To Chemicals

According to the American Cancer Society and a study by Harvard Medical School, there is a possible link between hair dye use and cancer, especially skin and breast cancer. Avoiding hair dyes means less exposure to potentially harmful chemicals, which can be better for your overall health.

5. You'll Enjoy Healthier Hair

Frequent dyeing can cause damage to your hair. Embracing gray hair allows your tresses to stay healthy and strong.

6. You'll Be A Positive Role Model

By embracing your gray hair, you can be a positive role model for other women and girls, encouraging them to normalize the aging process and be grateful for it.

7. You'll Embrace Change

New chapter in your life? Going gray can signify a new milestone and embracing change. Here's B+C editor Haley Sprankle (right) with her mom, whom she convinced to go fully silver. "She looks so cool with silver hair," says Haley. I couldn't agree more!

DO: USE A TEMPORARY COLOR BEFORE A PERMANENT ONE

As much as you may have a certain shade in mind, celebrity colorist and co-founder of dpHUE Justin Anderson recommends testing the waters first with a semi-permanent version. "It will gradually wash out after multiple shampoos," he explains. "Permanent color lasts much longer and will most likely require you to see a professional to get it fixed if something goes wrong." By starting with a semi-permanent dye, you'll be able to save yourself any hassle if it turns out you're not as big of a fan as you thought. (Photo via Charisse Kenion/Unsplash)

DON'T: LIGHTEN YOUR HAIR MORE THAN TWO SHADES AT A TIME

When you shift your hair more than two shades in a single session, it can be seriously damaging to your strands — not to mention unsightly. "Permanent color is typically formulated to lighten approximately two levels," explains David Stanko, vice president of technical design and education at Madison Reed. "If you try to bend this rule, the dyes will not be able to control the additional undertones exposed, and the result will be a color that is too warm or red, AKA brassy." If you want to lighten more than two shades, schedule multiple days (spaced a couple of weeks apart) to get the job done so your hair stays as healthy as possible.

DO: PICK A COLOR THAT COMPLEMENTS YOUR COMPLEXION

A flattering hair color is one that neither washes you out nor makes you look older than you really are. To figure out which shade best suits your complexion, take NYC-based Eddie Arthur Salon colorist Christine Neos' advice. "Hold a silver foil up to your face (representing ash tone), followed by a gold foil (representing gold tone)," she instructs. "You'll be able to see which reflects better on your skin."

From there, remember that opposites attract. "In the hair color world, this means that you should not pick a shade that matches your skin's undertones," advises Stanko. "For instance, if you have pink or warm undertones and choose a copper color, the combination of reds becomes overwhelming and your skin will look blotchy. For cool skin tones, a super-cool hair color will just wash you out to ghost land."

DON'T: CHOOSE A COLOR SOLELY BASED ON THE PICTURE ON THE BOX

Imagine having to wear a single dress every day for months at a time. Would you select it solely based on how it looks on the mannequin? Not a chance. The same goes for your hair tint. "What's pictured on the front of the box may not necessarily be the color that you are going to achieve," Anderson says. "It's important to pay attention to both the shade and the tone. Keep in mind that the color can be affected by any dye or treatments you may already have. If you are unsure about the color you should use, always lean towards something on the lighter side because you don't want to end up with a dark band in your hair."

Or, forget the front of the box altogether. Turn it to the side, which usually contains pictures showing what the result will be based on your current hair color. You could even head to Walmart, Walgreens, Wakefern, and Meijer to use Garnier's Shade Selector Tool. It allows you to virtually try on the entire range without ever touching your tresses.

DO: TOUCH-UP YOUR ROOTS WITH A ROOT PRODUCT

Selecting the right shade (and formula) for your roots is critical. "It's best to choose a product specifically designed to be a root touch up [like Revlon Root Erase ($10) or Clairol Root Touch-Up Semi Permanent Color Blending Gel ($10)]," says Revlon global master colorist Miquel Garcia. "If you use a traditional all-over permanent product, the color is likely going to be a darker, more vibrant color [since it's designed for your entire head as opposed to an in-between touch-up]. Root-specific products are designed [to be a bit lighter] to mimic your lengths and ends approximately two weeks after your last color."

That's not to say it's impossible to conceal your roots with regular hair dye, but Garcia notes that it can lead to more damage since you have to blend it down your mid-lengths and ends. To avoid any negative effects, he says the best and safest way to get your closest shade match is to apply the color allover but only leave it on for five minutes so it's less likely to wreak any havoc.

DON'T: DYE DAMAGED HAIR

While the process can revive lackluster color, it won't do anything for strands not in workable conditions. "When [strands are] split, dry, and damaged, the follicle is compromised and misshaped," says Courtney Goebel, the client education lead at eSalon. "Imagine a microscopic close-up of a single strand of hair. If healthy, the follicle will appear round and smooth. If damaged, it will look frayed, twisted, and wheat-like." Applying dye to the latter can be pretty tricky since it wont be able to absorb evenly. "This will cause an uneven, spotty shade, as still-healthy parts of the follicle may take in dye, while damaged parts are left uncolored," she says. (Photo via Valeriia Kogan/Unsplash)

DO: CHOOSE PRODUCTS FROM THE SAME BRAND

It may not seem like a big deal to combine a variety of brands together, however, when it comes to your tresses, it's best to take extra precaution and stick to just one collection. According to Stanko, hair color manufacturers create their products to specifically work together in a way that's healthy for your mane. He explains that when you mix one brand of color with a different brand of developer, you risk too-thick or too-thin formulas that won't evenly distribute throughout your strands. "Whether it's balance or viscosity that's off, it can lead to unpredictable color results," he says.

DON'T: LEAVE THE DYE ON FOR TOO LONG

As with most beauty treatments, leaving hair dye on your head for longer than recommended is never a good idea. "Timing is very important," Goebel says. "If a color has not been left on long enough, there is the possibility that your roots may be lighter (or darker) than your ends, your color won't come out as imagined, or your grays won't be covered." While most permanent solutions eventually stop processing at about the 40-minute mark, Goebel points out that leaving it on past that can actually lift the shade, causing what's known as hot roots, where that area gets lighter and doesn't match the rest of your head.

DO: CONSIDER THE BIGGER PICTURE

Sit down and listen up, because here's the real deal when it comes to at-home hair color. "Whenever you color your hair, consider time, cost, potential damage, and maintenance/frequency of coloring," Stanko advises. "The farther you travel from your natural shade, the more time it will take, the more it'll cost, the greater the potential for damage, and the more often you'll need to [dye] your hair." At the end of the day, you can't go from blue black to icy blonde without taking all these factors into account. "Social media has fooled us into thinking drastic color changes are easy, but remember that celebrities have a whole beauty squad behind them," he says. "When you see them [switching up their strands] a few weeks apart, you don't see all the energy, effort, expertise, hair extensions, and even photo filters that go into the look. Social media pictures might tell a story, but they never tell the whole story."
