The Right Way To Bleach Your Hair At Home

Blonde hair isn't a trend, but the tones and shades definitely change each season. The hair trend with perhaps the most longevity? It's got be platinum. Everyone from Kylie Jenner to Zendaya to your own next-door neighbour has rocked the hue at one time or another. Even our very own Mi-Anne Chan took the plunge and transformed her locks from brunette to blonde to pastel pink. So, why shouldn’t you?

Turns out, you don’t have to sink thousands into creating and maintaining a bright blonde — it’s totally doable at home (much like these self-isolation styles). Now, know that this concept will surely worry some. And yes, many pros, like Maria's colourist, Roxie Darling of Hairstory in New York City, will warn against it — but that doesn't stop many of us rebels from doing it successfully. So, if you’re brave, confident, and skilled enough, read on. Tip: Use your best judgment — this is not for everyone.

Step 1: Evaluate Your Risk
“The best and lightest results are seen on hair that is virgin — no hair dye at all — and shades that are light brown and [lighter],” says Alex Brownsell, Bleach London founder and celebrity colourist. You can do it on darker hair, but it will require some patience, and the damage will inevitably be greater.
Step 2: Prep
Bleach can strip your hair of life, so taking a few preemptive steps could mean the difference between silky, white strands and a damaged mop. “I’d advise doing lots of conditioning masks for two weeks before the actual bleaching to build up the strength of the hair,” says Brownsell. “And don’t wash your hair for a couple of days prior, since bleaching freshly washed hair can be slightly irritating to the scalp.”

Looking for a mask to protect and repair before you add more fuel to the fire? There are dozens of A+ hair treatments on the market today. We love the Shea Moisture Strengthen, Grown & Restore Treatment Mask, which works for a variety of hair types and serves up a serious dose of hydration.

We're also big fans of Kérastase Masque Elixir Ultime, which deeply moisturises parched strands while somehow still feeling weightless after you wash it out. They even have a specific masque for bleached hair to remove brash tones.

Step 3: Bleach

To start, mix the powder in a bowl with some developer, which will lift hair colour quickly and drastically, until the formula is about the consistency of yogurt. Darling recommends using a 30-volume developer.

Fair warning about this step in the game: The developer you pick is incredibly important, not only for safety, but for reaching your desired results. This writer has successfully used 40-volume developer for years to lift hair to a dramatic white-blonde sans extreme damage — but that takes major skill and a hair type that happily obliges. (Those with thin, brittle hair or a sensitive scalp should never use a developer that high, even with major experience.)

Moral of the story: Stick to a lower volume developer unless a colourist who knows you and your hair instructs otherwise. Even with this warning, however, we still suggest seeking the advice of a professional when picking your products.

After putting on some rubber gloves, use a tint or dye brush to apply the bleach all over your head, parting hair with the pointy end of the brush to get as close to the roots as possible. Let the bleach sit for 30 to 45 minutes, checking in the mirror periodically until your hair is a consistent light-yellow colour.

Full disclosure: If you have darker hair, you'll need to go through the bleaching process a few times in order to see full results. Our pros advise waiting a few weeks between every bleach. If you OD on the stuff, it could damage strands to the point that they'll start to fall out. If a slow transition is not for you, you'll need to visit a salon professional.

If you have really dark hair like me, it'll be difficult to take your strands from their natural tone to blond in one sitting. However, having done exactly that using Bleach London's Total Bleach Kit just last week, I can confirm that it is possible. Dare to dream, people.

Bleach is not good for your hair, full stop. So if your hair is already light you can opt instead for this bleach alternative high lift tint kit which will cause less scalp irritation and damage to your hair. But beware, it will only lift your hair up to five tones which means that if you use it on dark brown hair, you will end up copper (I speak from experience). But of course, if copper is your thing, be my guest.

Step 4: Tone
After rinsing out the bleach and lightly shampooing, it’s time for the most important step — the one that makes hair a cool white, rather than a brassy yellow. Apply a toner, like Bleach London's, all over damp hair, and let it sit for about 20 to 30 minutes. This step can be a little messy, so relax in the tub while you wait. Rinse thoroughly, and finish with the rejuvenation hair mask which comes in the box.

Toner kits don't have to be terribly expensive either, so don't worry about quality control. This Bleach & Toner Kit from Bleach London is easily available and leaves a bright, frosted 'do behind.

Step 5: Rehydrate and rejuvenate

Even when I didn't dye my hair I still lived for a hair mask. But now I've hopped on the bleach blonde bandwagon I see just how necessary they are. Honestly, my hair is so thick and knotty after bleaching you can't even run a comb through it, which is perfectly normal by the way.

Straight after washing out my toner I always put on a hair mask. Olaplex isn't the cheapest formula, but it comes very much salon-approved and I choose to put my trust in the pros to make sure my hair doesn't come out in chunks.

I leave Olaplex No.3 in for at least 20 mins - longer if I can be bothered - and then wash it out with warm water. After that my hair feels silky smooth and hydrated again. I repeat this once a week to keep my hair in good condition.

Step 6: Maintain
“Maintain with Bleach Silver Shampoo and Conditioner,” Brownsell advises. These purple products will offset all that gunky brassiness and restore hair to a lustrous white. (Leave in both the shampoo and conditioner for a slight deposit of violet, which will keep your locks an icy shade of platinum.) Continue using a mask treatment once a week to keep hair strong and healthy, and regularly apply a strengthening leave-in oil, like this treatment, to your ends.

To keep the colour vibrant and lessen the risk of drying out your ends, opt for a product without ammonia like purple shampoo. After bleaching, slather on a healthy dose of the coloured formula and leave it for 10 minutes, then rise. Et voilà!

Don't underestimate the power of a leave-in. Danilo, who's done Gwen Stefani's hair for over 20 years, can attest to this. “Leave-in conditioners — that's really the secret," he once told us. "So many people are blow drying and using hot tools, which is where most of the damage happens — so I'm always telling people to learn how to work with leave-in conditioning at every stage of styling.

I use the Moisture Leave In Creme from Pantene on almost everyone; it’s a wonderful cream that leaves the hair moisturised. I mist it onto clean, dry hair to start, then I put in my volumisers, and maybe mousse, depending on the hair. I dry them in with a mixed-bristle brush, always blowing in the direction of my style. And then I'll go back in with my tools, using cream on small sections throughout. You can reapply it over and over on set and it doesn’t get greasy."

I can personally attest that this leave-in conditioner has been something of a miracle for my heavily-abused hair. The formula contains keratin to repair proteins leaving my hair looking hydrated and shiny while maintaining my ethereal silver colour. It's gentle enough to use every day, but the best thing is that it also protects against heat styling which means I can use a hair dryer without drying out my strands. Hurray!

No matter how well you take care of your newly-bleached hair, there will come a time when it needs some heavy-duty hydration. That’s when you turn to this insanely rich, intense masque, which is packed with glycerin and plant extracts to deeply moisturise even the driest, most damaged lengths and ends. A little goes a long way and makes a huge difference.
