The process can vary at different salons, but typically, a hairstylist will start off by washing your hair twice with a clarifying shampoo. Keratin is the type of protein that makes up your hair, skin, and nails. Keratin is a protective protein, less prone to scratching or tearing than other types of cells your body produces. Keratin treatments shouldn’t be done more than three times a year, as over time they can start to damage hair.

Keratin Treatment Benefits

A keratin treatment is a chemical process on the hair to achieve soft and shiny hair that was otherwise frizzy [2]. So are you wondering why you need keratin treatments when it is naturally present in your hair? That is because your hair loses keratin with time due to sunlight, pollution and harsh hair treatments.

To best use Paul Mitchell's Awapuhi Wild Ginger Keratin Intensive Treatment, begin by applying a small amount to clean, damp hair, ensuring even distribution throughout. Allow the treatment to deeply condition your hair by leaving it on for 3-5 minutes. After the waiting period, thoroughly rinse your hair to remove the treatment. Remember, the goal is to keep your hair looking its best while ensuring the treatment lasts as long as possible. The products I've listed below are curated with that exact purpose in mind.

Types of Keratin

The keratin in these treatments may be derived from wool, feathers, or horns. Certain shampoos and conditioners contain keratin, but you’ll typically get the greatest benefits from a salon treatment done by a professional. It’s also a great source of vitamin C, a water-soluble nutrient that doubles as an antioxidant. This vitamin likewise helps stimulate the production of collagen, a type of protein that maintains the strength, structure, and elasticity of your skin (20, 21, 22). As a result, this lightweight lather has quickly become one of our all-time favourite volumising shampoos for fine hair. Not only does it smell incredible, but it also delivers a thorough cleanse that doesn't leave your hair feeling stripped or squeaky.

Matrix A Curl Can Dream Light Hold Gel is an excellent choice for those with keratin-treated hair, especially if they have natural curls or coils. This gel's formula is infused with Manuka honey extract, which ensures that your treated hair retains its moisture and luster. Its light-hold composition ensures that your curls are defined without the stiffness or crunchiness common in traditional gels.

Applying a leave-in conditioner can also help protect the hair and keep it feeling moisturized. Your hair, nails and skin rely on the amount of keratin in your body for their overall health. After that, a keratin treatment or solution is applied to your wet hair and combed through.

Blonde Assure Purple Shampoo contains keratin protein (the hair’s building block) plus a purple pigment to help neutralize unwanted yellow and orange tones that tend to pop up in bleached hair. If you want to cut down on blow-drying and straightening on a regular basis and still want super smooth and shiny hair, go for keratin treatments. Talk to your hairstylist about glyoxylic acid keratin treatments in case you have extremely thin hair prone to heat damage.

Is it a better option than other hair treatments?

The fingernails, hair, and skin need keratin to grow, function, and stay healthy. If a person cares for their hair appropriately, uses suitable products, and does not wash it too frequently, results of the treatment can last up to a few months. It is also advisable to refrain from coloring the hair for at least 2 weeks after getting a keratin treatment. This allows the treatment time to set and helps prevent damage to the hair. Keep scrolling to learn everything you need to know about getting a keratin hair treatment. When performed by a hair care professional, your hair will be smooth and voluminous for up to six months.

However, if you're tethered to your curling iron or want your hair to look picture perfect on the daily, you're gonna suffer some heat damage. That is why people should use them sparingly and avoid repeated exposure to harsh chemicals and heating elements. A considerable advantage of keratin hair treatments is their long lasting effects. They can greatly reduce the time spent styling the hair every day, particularly if the hair is frizzy or thick. Some employees at hair salons even reported nosebleeds and respiratory problems from handling the keratin treatment products and inhaling their fumes repeatedly over time.

Risks and Side Effects

This means you won't need to apply as much heat and tension to your hair to dry it off. Like many salon treatments, a keratin treatment starts with shampooing. This gets your hair squeaky clean, so when the keratin treatment is applied, it can really sink in and bond to your strands. Soekoro notes that acid treatments are typically applied to wet hair and rinsed out, whereas water-based treatments are typically applied to dry hair and left in. When blow-drying, use a lower heat setting to avoid damaging the hair, and use a heat protectant product before using any hot styling tools. It is also important to use sulfate-free shampoo and conditioner to help prolong the treatment.

Vitamins, minerals, and hair loss: Is there a connection?

Plus, I can maintain the look I love with minimal heat, allowing me to focus on hair health and growth. With a stronger follicle, Roque explains that your hair is better able to retain water in your hair. I can apply as many moisturizing, hydrating products as I want but it doesn't retain any of the moisture. Because keratin treatments create that armor around hair, its better able to accept and retain the moisture I give it, explains Roque. Primarily, there are two types of keratin treatments out there — those with formaldehyde and those without it. "It's creating a barrier that will be temporary for a couple of months," says Roque.

Hair Setting Sprays

If you're introducing keratin shampoo into your regimen, Hallajian suggests using it consistently for about two weeks. "Then, alternate it with another product to not overuse the keratin in the hair," she says. Keratin shampoo can also be used on extensions as long as they are made from human hair.

Potential risks of keratin treatment

Salt water, chlorine exposure, excessive washing, using sulfate-based products, and excessive heat without a protectant can reduce the longevity of a keratin treatment. While not compulsory, using a keratin shampoo after a keratin treatment is highly recommended to prolong the treatment's effects and keep hair smooth and frizz-free. UNITE EXPANDA Dust Volumizing Powder is a versatile hair product that blends the benefits of texturizing spray and dry shampoo. With its lightweight formula, it doesn't weigh down your hair and leaves no visible residue. To use, spray evenly all over wet or dry hair for instant smoothness and natural shine. It's perfect for a pre-blow-dry prep or for a mid-day hair refresh, adding a touch of elegance to your style.

They’re also loaded with vitamin C, which promotes collagen synthesis to support hair, skin, and nail health. Plus, this vitamin aids wound healing, alleviates inflammation, and protects against skin damage (21, 22, 25). Mangoes are also high in several other key nutrients for skin and hair health, such as vitamin C and folate (16). What’s more, eggs’ protein promotes keratin production, with 6 grams of protein packed into one large, 50-gram egg (2).

And while we're certainly pro-curls and pro-frizz at Byrdie, keratin treatments are an effective way to straighten and smooth the hair if that's what you're after. Many keratin hair treatments contain formaldehyde, which is a chemical used as a germicide, fungicide and disinfectant. Funeral homes and medical laboratories also use formaldehyde in dead bodies so they don’t break down as quickly.

There has been some controversy surrounding keratin treatments, because they use formaldehyde or other chemicals that release formaldehyde. After your hair treatment, you shouldn’t get your hair wet for several days or pull it back with hair clips, scrunchies (elastics), hats or sunglasses. You may have to use special shampoos and other hair products to maintain the treatment. Keratin hair treatments are chemical protein treatments that make your hair shiny and silky while also reducing frizz.

Those with formaldehyde are much more effective, and the effects last longer than those without. We dove deep into the technology behind volumizing hair products, learned about the history and chemistry behind antiperspirants, and read up on Accutane. The hours-long, in-salon remedy works to de-frizz and de-puff, but how does it work? To get some answers, we talked to the team at Keratin Complex along with pros in the hair industry.

Debuting her new hair colour with a perfectly timed transition video, we were quite frankly shook. "Bubbly blonde content creator" was very much her vibe when we met her on Love Island season 10 last year, and her going dark really wasn't on our bingo card, so we can't lie, it's boggling our brains a bit. Beauty Supply owner Emaly Baum can make you a blonde, but she's also great with brunettes and redheads. Before lightening locks, talk to your client about the kind of highlight placement they’re looking for. All techniques can be dialed up or down depending on their desired look, meaning anything is possible, from soft and subtle to bold and dramatic. My journey in the hair industry hasn’t always been an easy one but I have always paved a pathway to differentiate myself and my skills.

The cherry blonde hair color can be super customizable and since this color features an array of tones, your best bet is to book an appointment with a professional.

It would be best if developers like 30 or 40 were used only when trying to go lighter. A 10 developer is going to deposit only, and a 20 developer will lift and deposit. So if you have any grey hair, you will need to use a 20 developer to cover your grey hair fully. Using a filler is by far the most crucial step you are going to HAVE to do!

Get ready, it might be a bit of a shock…

The pros recommend using a filler that’s at least two shades lighter than your desired outcome. If you’re looking for a lived-in hair color to minimize root maintenance, try the L’Oréal Paris Superior Preference Balayage At-Home Highlighting Kit. This at-home balayage kit includes a precise applicator to mimic the hand-painted strokes that are synonymous with balayage highlights.

Sofía Vergara's waterfall locks are highlighted throughout with a warm caramel blonde. "If you have enough of your natural brunette mixed in with the right shade of blonde, it's extremely flattering on anyone," notes Richards. "I truly wouldn’t recommend attempting this or any look involving highlights at home," says Richards. "Something like this can go very wrong because brunette hair tends to pull very orange/yellow tones."

Kate Beckinsale's lovely shade of auburn comes courtesy of a blend of highlights and lowlights. Supermodel Doutzen Kroes looks absolutely sensational in this bronde shade. Her bouncy ponytail shifts from a brown to golden bronde ombré that beautifully catches the light.

There is no instance where I would recommend an actual box dye from the store. They have a few different brown options, and they can be mixed to match the custom color on your head. Dark hair takes up over half of the color chart, which means the possibilities are endless.

Meanwhile, the face-framing highlights also work to brighten her complexion. Halle Berry's honey blonde highlights and shag offer a casual—but still chic—variation on the standard boho blonde. The supermodel has experimented with several hair colors, but this toffee color with its collarbone-grazing length has our hearts.

The ideal technique is to get your hair coloured in the salon with a precise assessment and a personalised treatment. At Jean Louis David, we use a Gloss treatment as an intermediary step to prepare the hair. This service allows the hair fibre to hold colour pigments more easily. Then, the colourist will apply your chosen colour, using the right amount of product depending on your desired look and the condition of your locks. There is a lot of room for error and you could end up damaging your hair. "Box dye would be fine for a gradual transition but not brunette to blonde," Solano says.

You need to take a few extra steps when going back brown to ensure your hair doesn’t look muddy or have a green undertone. I miss the days when Caroline Calloway shared every aspect of her life on the internet, mostly because I'm so enchanted by her style. Luckily, she's still down to offer some insight—if you know when to catch her. "I'm literally at Sally Hershberger right now," the Scammer writer shared when I reached out about her favorite colorist. This photo is an example of foilyage that ensures brightness with seamless results, incorporating various amounts of natural and added dimension and giving beige blonde vibes. She has also written for WomensHealthMag.com, Elle.com and HealthCentral.com.

And while traditional ombré hair typically features natural, darker roots that fade into lighter, highlighted ends, "reverse ombré hair"—as the name implies—is the reverse. As in, the following hairstyles have totally flipped the world of ombré on its head. Once you have brown hair with blonde tips, it’s time to make a few changes to your hair care routine to help keep your mane looking and feeling its best. It’s Cami here, delving into the color-filled world of hair transformation.

Stylists recognize 10 levels of hair color, from dark brown to light blonde hair shades. Applying blonde hair dye on a brown base will not help you achieve any change – before you dye your brown strands lighter, they should be “lifted,” which is stripped of their naturally dark color. As you might have guessed, the more dramatic the change, the more damage to your hair. This is why the rule of thumb is to go only two shades higher within one appointment and never to apply bleach to hair that is already compromised. Bronde hair can easily be manipulated to suit warm or cool skin tones, making it the ultimate neutral shade. It’s a blend of brown and blonde hair color which gives off natural looking highlights.

#2 There’s a shade for everybody

Understand the current condition and shade of your blonde hair. Consider factors like whether your hair is naturally blonde or previously dyed, the presence of highlights or lowlights, and the overall health of your hair(1). Blonde hair, devoid of red undertones, often rebels against brown dye. “Sunlight oxidizes color, making it lighter, brassy or both,” says Brown. While you can’t get away with avoiding sun exposure to your strands, unless you wear a hat 24/7, you can help get rid of the brassiness it causes by using a clarifying hair rinse. Brown recommends dpHUE Apple Cider Vinegar Hair Rinse, which not only helps maintain color but also leaves your strands soft, smooth and cleansed.

What should you do before your salon appointment?

This hair color is also ideal for those who can’t quite make up their minds between the two colors. Because this color is highly customizable, visit a professional colorist rather than attempt this on your own, especially if you’re an at-home hair color newbie. Sand colored hair made its way onto the big trends list seasons back and going into 2022 we still can’t get enough of the look.

The duo have collaborated on an impressive array of shades (blue!), tones (blue-gray!), and surprising platinum piece placements. "I love my colorist! She’s been coloring my hair since 2015 and always does a bang-up job, even when navigating the fraught state of my chemically traumatized hair," says the writer. That can be overwhelming—especially if you live in New York City.

And, of course, we can't get enough of those perfect beach waves, either. Whether it's a regular ombré or a reverse one, we always love the look of a natural hue combined with an out-of-this-world one. This white platinum blonde-meets-ice blue creation is unexpected yet amazing. "If you love your natural color and it works with the color on the ends, I say go for it," says Swinney.

To use the John Frieda Brilliant Brunette Color Deepening Treatment to go brunette, simply apply to slightly wet hair, leave on for 5-10 minutes, and then rinse out. Go for a bright and bold color up top while keeping it natural at the bottom. Bonus points for these braids that add a touch of glam with beaded tips.

If you have blonde hair you can easily go from blonde to light brown at home. Marie Claire contributor Katherine J. Igoe first met Kimberly Cannon "approximately one million years ago" when she was first living in New York and needed an inexpensive highlight. "She somehow has given me the softest, lightest, most dimensional blonde of my life—and it grows out amazingly. She did my wedding highlights. That's how much I love her." With over 20 years of experience in the hair industry, Wellington Hair Salon founder Patrick Wellington prides himself on techniques that are both personalized and flawless. Specializing in natural and textured hair, his objective is to create "hair that glows with inner health"—an excellent outlook for a colorist, as we all know bleach can wreak havoc on your precious strands. "In New York, people are always looking to make a statement," shares hair transformation specialist Lucille Javier, who works at the genius-colorist-studded Mark Ryan Salon in Manhattan.

Blonde & brown hair: Top tips for a smooth hair-transformation!

Remember to start with a darker golden blonde base on the lengths and use lighter face-framing highlights to tie it all together. Hit up the salon, since a pro colorist will have the skills to create custom highlights that are sure to suit you. There is no world in which this list wouldn't include Jenna Perry. Beloved by a host of (quite famous) cool girls including Emily Ratajkowski, Tommy Dorfman, and Bella Hadid, Perry works out of her namesake salon, Jenna Perry Hair Studio, in SoHo and the East Village. The inventor of "hot girl hair," Perry is a balayage master who can tackle an all-over color if that's more your jam (no, I can't stop thinking about Hadid's dark gloss from December 2023).

With piecey fringe, Rihanna showcases the versatility of the blend. Here she is rocking heavy blonde highlights on top of her natural dark roots for tons of depth in an otherwise short coif. Use a system of shampoo and conditioner formulated for color-treated hair.

Just like going from brown to blonde, the opposite transition requires a great deal of upkeep. You also want to be choosy when it comes to your at-home care since certain ingredients and brands might react differently on your brown hair than it did on your blonde. Going from brown to blonde hair requires bleaching — and the darker your starting shade, the more work may be required to reach your desired shade of blonde hair.

This approach wards off an unnatural finish, ensuring a seamless transition. Remember, the deeper the brown, the more it may deviate from the color shown on the dye box—especially if you’re venturing more than two shades darker. It’s important to be choosy with your shampoos and conditioners, especially if you’re trying to revive color. Consider brands that are formulated for brunette hair, like dpHUE Cool Brunette Shampoo and dpHUE Cool Brunette Conditioner.

This coffee-inspired hue is just as dark and delicious as your morning cup of joe. This cool shade pairs beautifully with medium to dark skin tones and eye colors. You can use the L’Oréal Paris Superior Preference Fade-Defying Shine Permanent Hair Color in Cool Dark Brown to get that rich dark brown shade you desire. Brown hair regrowth will be very much visible on blonde hair color. Root concealers can now help you out with that, but don’t let them delay your touch-up appointment! Larger regrowth is a huge challenge for a stylist, as heat from your scalp will make hair near the roots process faster, so there is a risk the applied hair colors won’t match.

Simple things like your skin’s underlying tone and your eye color will play a big role in what color you should dye your hair. The pieces in front are a bit pinker in color because I rebleached them, and therefore, the filler color took better than the filler put on the rest of my outgrown blonde hair. A semi-permanent hair dye will last about a month if you shampoo your hair every other day. She isn't afraid of thick strands or time-consuming transformations.
