What is hair bleach?

Hair bleach is not what you clean the toilets with!

It’s a powerful hair coloring product that lightens the color of your hair.

It works by lifting your hair cuticle and breaking down the pigments in your hair, making them lighter in color by a shade or two. Hair bleach can be used to achieve a variety of looks, from highlights to an all-over lightened platinum color.

Bleaching your hair is a commitment, as it can take multiple sessions to achieve your desired look and can damage your hair if not done properly.

However, when done right, bleaching your hair can be a fun way to experiment with your look.

Hydrogen peroxide is the most common bleaching agent used to lift and lighten hair color. It penetrates your hair shaft to strip it of color in a permanent process.

Like all bleach, it’s toxic so you need to be careful when handling it. And yes, it damages your hair so you need to look after it before, during and after.

Step 2: Mixing the Bleach

Once you have all your tools gathered, it’s time to mix the bleach according to the instructions on the package.

Most kits will require you to mix the bleach powder with developer cream in a non-metal bowl. Be sure to follow the directions carefully!

Once the bleach mixture is ready, it’s time to apply it to your hair.

Step 3: Applying the Bleach

It’s time to get started! First, put on your gloves and old clothes. Then, drape the old towel over your shoulders to protect your clothing from any potential stains.

Start by sectioning off your hair to make it easier to apply the formula.

Start at the roots and work your way down to the ends. Be sure to thoroughly saturate each section of hair; otherwise, you’ll end up with uneven results.

Step 4: Development time

Once you’ve applied the bleach evenly throughout your hair, put on a shower cap and wait for the right amount of time before rinsing out.

As a general guide to how long you should leave bleach in your hair, you shouldn’t leave it in for more than 30 minutes.

But this does depend on the condition of your hair, the base color to begin with and whether your hair has been dyed before.

Step 5: Rinse and tone.

After 30 minutes have passed, hop in the shower and rinse out the bleach until the water runs clear.

Bleached hair typically leaves some warmer tones of red or orange, so you may want to use a toner at this stage to get rid of any unwanted brassiness.

You can skip this step if you’re planning to dye your hair another color!  If your hair is in good condition, just grab your chosen box of hair dye and follow the instructions.

Then shampoo and condition your hair as usual, and style it however you like!

Top Tips for Bleaching Your Hair at Home.

Do a patch test. Before you start bleaching your hair, it’s important to do a patch test first. This will help you determine if you’re allergic to the bleach and/or the developer.

Simply mix together a small amount of bleach and developer, apply it to a small section of skin on your inner arm, and wait 48 hours to see if any irritation develops.

Read the instructions. We know that bleach kit instructions can be long and confusing, but trust us—it’s worth taking the time to read them before you start the bleaching process.

That way, you’ll know exactly how much bleach and developer to mix together, how long to leave the mixture in your hair, and what kind of aftercare is required.

Invest in some good quality products. When it comes to bleach, you get what you pay for. That’s why we recommend investing in some good quality products—bleach kits from reputable brands tend to work better and cause less damage than cheaper alternatives.

Don’t skip the aftercare steps. Once you’ve removed the bleach from your hair, it’s important to follow the aftercare steps specified in the instructions (usually this involves shampooing and conditioning with products designed for bleached hair).

By doing this, you’ll help keep your locks healthy and hydrated.

Will bleach damage my hair?

Of course, bleach is bad for your hair as the processing dries it out and can turn it into a frizz factory.

So you need to prepare it for harsh treatment by giving it some love in the run-up to bleaching day.

Take a look at the health of your hair too. If it is dull and lifeless and lacking in lustre, bleaching your hair might not be right for you at this moment.

It also makes a difference if you have virgin hair (hair that has never been dyed) or dyed hair too. Have a chat with your hairdresser about your options.

You can also try a hair bleach bath which is a gentler way to bleach your hair, but it’s not as strong so you may not get the lift you desire.

The main thing is to be careful you don’t damage your scalp if you have sensitive skin.

How can I take care of my hair after bleaching?

After you’ve stripped your color and achieved a fabulous blonde look you love, you’ll want to deep condition your hair regularly and avoid a lot of heat styling if you can.  

Your hair will be fragile and more prone to breakage and split ends for a couple of weeks. Use a shampoo and conditioner for bleached hair that will help to replenish and restore your hair shafts.

Use a hair mask or deep conditioner once a week to replace lost moisture and nourish your hair.

Go easy on using hot tools like a blow dryer, curling tongs and flat irons. When you do heat style, use a heat protectant every time.

Hair toners and hair glosses will keep your color cool and bright and get rid of any unwanted brassiness and brassy tones. You can use them as soon as your hair is bleached to banish orange and yellow tones.

You’ll also need to use specially formulated silver and purple shampoos and conditioners to keep the color in tip top condition.
