How to Safely Bleach Hair at Home

Bleaching your hair can be an exciting way to give yourself a new, bold look. However, it comes with a price—damage. Whether you’re lightening blonde or dark hair, there are measures you can take to protect your hair from harsh chemicals. The best way to minimize damage is by using a deep conditioning treatment before and after bleaching. In this guide, we’ll teach you everything you need to know about safely bleaching and restoring your hair’s health.

Best Way to Bleach Hair with Minimal Damage

Wash your hair 24-48 hours beforehand to allow natural hair oils to build.
Divide your hair into four sections and clip the top sections out of the way.
Mix 1 part powdered bleach and 2 parts low-volume developer in a plastic bowl.
Apply bleach with an applicator brush from the tips to the roots to apply evenly.
Let it sit for 20 to 45 minutes until you reach your desired shade.
Rinse with neutralizing shampoo and warm water.
Allow your hair to air dry and apply a deep condition mask.

- Inspect the bleached strand to get an idea of your hair’s appearance afterward. You can adjust the processing time to get a lighter or darker shade if necessary.
- If bleach irritates your skin, try shortening the processing time or look for alternatives, like permanent dyes.
Warning: If your skin starts itching or burning, wash the bleach off immediately. If it continues, have a doctor examine your skin.

Expert Interview. 25 February 2022.} Low-volume developers produce weaker bleach, causing less damage. It may take longer to achieve your desired results with a 10- or 20-volume developer, but it'll help minimize the damage. Choose a bleaching kit with a low-volume developer, or purchase your bleach powder and volume developer separately to choose a low-volume developer.^{[7]

Research source}
- You can find a 10- or 20-volume developer at a beauty supply store or online.
3
Wait 3 weeks in between bleaching sessions for dark hair. Removing the pigment from dark hair requires multiple bleaching sessions. Give your hair at least 3 weeks to give your hair cuticles enough time to heal, close, and lay flat again. During this time, use a deep conditioner daily to repair your hair.^{[8]
X
Research source}
- Repeated bleaching puts your hair at risk of overprocessing and breakage.
- If you want to speed up the process, seek out the help of a professional hair colorist. Professionals have better bleaching formulas that may cause less damage. Similarly, they can advise you on the best way to get your desired results.^{[9]

Use Color Oops and shorten your bleaching time to 30 minutes for dyed hair. Unlike natural hair, which can easily be stripped of its color, dyed hair can make it harder for the bleach to lift color. As a result, your hair may look patchy. Use a color stripper, like Color Oops, to remove the dye. Then, go in with the bleach and shorten your processing time to 30 minutes or less to limit the damage.^{[10]

- It’s best to see a professional colorist if you have dyed hair. They can advise you on striping hair dye and cover patches without causing more damage.
Warning: If you've dyed your hair very dark, go to a professional stylist. Otherwise, you may damage your hair beyond repair.^{[11]

Protect your skin with an old towel, gloves, and coconut oil. As you apply bleach to your hair, you may drip it onto your clothes and skin. To protect yourself, drape an old towel over your shoulders.^{[12]

- Use baby oil or argan oil as a substitute.
- Purchase a hairdresser’s cape if you don’t want to discolor old towels.
2
Add bleach and low-volume developer in a plastic bowl and stir. Use 1 part bleach and 2 parts low-volume developer to lessen the strength of the bleach. Pour both ingredients into the mixing bowl. You may notice some bubbling as you stir the ingredients with a plastic brush applicator.^{[14]
X
Research source}
- 30- or 40-volume developer is recommended for dark brown or black hair. However, it’s best to stick to 20-volume to minimize damage.
- Opt for blue or purple bleach powder to reduce the risk of brassiness afterward.
- Always use a plastic bowl when handling bleach because bleach can react with metal.
Tip: For an easy option, purchase a bleaching kit that contains both a bleaching powder and a developer/peroxide. These are sold at most beauty supply stores and online.

Divide your hair into 4 sections to bleach your entire head evenly. Split your hair in half vertically, then in half horizontally to create 4 sections. Secure the top sections with plastic clips. Professional Hair Stylist Arthur Sebastian suggests having an adequate separation of each section to coat your hair evenly from tip to root. Apply bleach to one of the bottom sections, working from the ends up to the roots. Repeat the process for each section.^{[15]

- If you have very thick hair, you might create 6 sections to make it easier to apply the bleach evenly.
- Do your best not to get the bleach on your scalp. The bleach may burn or irritate your scalp if it gets on your skin.
Warning: Always use plastic clips when bleaching your hair. Metal clips can react with the bleach and may damage your hair.
4
Use a highlighting cap to do highlights, optional. Place a highlighting cap over your hair. Pull your hair through all of the holes or just some of them with a hook or comb, depending on how many highlights you want. Use your applicator brush to cover all of the exposed hair with bleach starting from the tips to the root.^{[16]
X
Research source}
- Applying bleach directly on the cap may seep through the holes and onto the rest of your hair, creating splotches.
Variation: Clip your hair into 4 sections for all-over highlights or 2 sections for highlights only on the top of your hair. Let down the first section of hair, then use the end of a comb to separate a small piece to highlight. Place a piece of foil under the hair you want to bleach. Apply the bleach to the hair, then fold the foil up over it to protect the rest of your hair from the bleach. Work your way around your head until you have your desired amount of highlights.
5
Bleach different sized pieces of hair for a balayage effect, optional. Clip the top part of your hair and start with the bottom section. Select a thin piece of hair and bring it over your shoulder. Use gloved fingers or an applicator brush to paint the bleach on the tips. Move to the other side of your head, pick up another wispy piece, and repeat. Alternate back and forth to create more natural-looking highlights. It’s okay for the bleached pieces to be different sizes.^{[17]

- Cover the ends with aluminum foil to separate them before proceeding to the top part of your hair. Use the same method of application to complete the look.
6
Cover your hair in plastic wrap for 20 to 45 minutes. Bleach starts working immediately, but reaching your desired shade will take some time. Bleach can sit up to 45 minutes before rinsing to avoid overprocessing and breaking your hair. Check the color every 5 to 10 minutes to see how it’s progressing.^{[18]
X
Research source}
- Keep in mind bleach will cause less damage if it’s on your hair for the least amount of time.
- If you’re unhappy with your results after 40 minutes, bleach it again in 3 weeks to avoid damaging your hair. Alternatively, you can speak to a professional colorist for assistance.
7
Rinse your hair with neutralizing shampoo to remove the bleach. Rinse out the bleach using cool water. Then, use your fingers to massage a quarter-size amount of mild or neutralizing shampoo to your hair. Use the tips of your fingers to remove any bleach from your scalp. Then, wash it under a stream of warm water.^{[19]

Research source}
- Make sure you remove all of the bleach from your hair. If necessary, shampoo your hair again to remove all the bleach.
- Neutralizing shampoo helps balance the pH levels of your hair and scalp after bleaching to ensure your hair remains healthy, shiny, and free of damage.^{[20]

If your bleach job has an unwanted yellow or golden tone, use toner to replace warm tones with cool, pure white tones. Combine equal parts toner and low-volume developer in an applicator bottle or mixing bowl. Use an applicator brush and apply it all over the hair. Rub it in and let it sit for 10 minutes. Rinse with water afterward.^{[21]

After you bleach your hair, it’s best to avoid heat styling to prevent further damage. Allow your hair to air dry after washing the bleach and apply smoothing cream to minimize frizz.^{[22]

Variation: If you must heat-style your hair, apply a heat protectant before you style it to minimize the damage to your hair. Then, blow dry it on low to medium heat.

Use a deep conditioning mask daily the week after bleaching. Bleaching your hair removes the moisture, so it’s important to use a deep conditioner to repair it. For best results, coat your hair with a deep conditioning mask, then let it sit for 30 minutes. Rinse with cool water.^{[23]

Research source}
- Always rinse out conditioner with cool water because it closes your hair shaft, which gives you shinier hair.
Tip: You don’t need to shampoo your hair every day. It’s okay to use your conditioning mask.
2
Apply a bond-repairing treatment weekly to restore your hair. Bond-repairing treatments are designed to repair your hair and leave it shiny. Look for products labeled bond-repairing. Apply a large dollop of the product to your hair, then comb the formula through your strands. Let the treatment set on your hair for at least 30 minutes. Then, shampoo your hair for softer, shinier hair.^{[24]
X
Research source}
- It’s best to leave the treatment on for several hours so it has more time to work. For instance, you might leave it on overnight. Just cover your hair with a sleeping cap.
- Bond-repairing treatments are available over-the-counter and through a salon. While you'll get better results at a salon, home treatments may help you achieve healthier hair.
It’s normal for blonde hair to get brassy or orange, but purple shampoo can neutralize the discoloration. Pick a purple shampoo designed for your shade of blonde. Use your purple shampoo once a week in place of your regular shampoo and rinse with cool water.
4
Bleach your roots every 4-6 weeks to keep your color consistent. It’s best to bleach your roots before they get too long so that you don’t get a noticeable shade difference. If you wait too long, you might need to bleach your entire head of hair to get a consistent blonde. Touch up your hair every 4 weeks if it grows quickly or every 6 weeks if your hair grows slowly.^{[25]
X
Research source}
- Try not to let your roots get more than about .75 in (1.9 cm) long.
After bleaching your hair, you’ll likely end up with split ends. Leaving your split ends unattended to will cause your hair to continue to break, which means cutting off more inches in the long run. So, stay on top of your hair. Plus, regular trims prompt hair growth which means healthier hair.^{[26]

Expert Answer

So what you want to do is lift the orange roots and combine the bleach there, preferably in foils so you have an adequate separation in each section. Then, you lift the root from orange to blonde. I would suggest doing a shadow root just a half shade darker than the rest of your hair to create a color meld, which is a smooth separation between the roots and the rest of your hair.
