Bleaching at home carries risks, including hair damage, breakage, scalp irritation, and uneven color. Proceed with extreme caution, and consider consulting with a professional stylist before attempting this.
I. Understanding the Basics
* What Bleach Does: Bleach (usually a mixture of a developer and a lightener) penetrates the hair shaft and oxidizes the melanin (pigment) in your hair, making it lighter. The longer it's left on and the stronger the developer, the more pigment is removed.
* Developer: This is hydrogen peroxide in different strengths (volumes). Common strengths are 10, 20, 30, and 40 volume.
* 10 Volume: Lifts very little, used for depositing color or subtle changes. Causes the least amount of damage.
* 20 Volume: Lifts 1-2 levels. Good for fine hair or slight lightening.
* 30 Volume: Lifts 2-3 levels. More common for at-home bleaching. Can cause damage if not used carefully.
* 40 Volume: Lifts the most levels. Generally NOT recommended for at-home use due to the high risk of damage and chemical burns. Should only be used by experienced professionals.
* Lightener (Bleach Powder): This is the powder you mix with the developer. It comes in different colors (blue, purple, white), which can help tone the hair during the bleaching process. The color is not the bleach itself.
* Blue and Purple are used to counteract warmth as they are opposite of orange and yellow on the color wheel.
* White is typically used when you are trying to get very light blonde.
* Toner: Used *after* bleaching to neutralize unwanted tones (yellow, orange) and create the desired final color.
* Levels of Lift: Hair color is measured in "levels," with 1 being black and 10 being the lightest blonde. Bleaching lifts your hair color by a certain number of levels. Understanding this helps you choose the right developer and processing time.
II. Before You Start: Preparation is Key
1. Do Your Research: Watch videos, read articles, and understand the process thoroughly.
2. Strand Test: This is non-negotiable. Mix a small amount of the bleach mixture and apply it to a hidden strand of hair (e.g., underneath near the nape of your neck). This shows you how your hair will react to the bleach, how quickly it lifts, and if it will cause damage. Check every 10 minutes, and rinse when you've reached your desired level of lift.
3. Allergy Test: Apply a small amount of the developer and bleach mixture to your inner arm and check for a reaction after 24-48 hours.
4. Gather Supplies:
* Bleach powder (lightener)
* Developer (10, 20, or 30 volume, depending on your hair and desired lift)
* Toner
* Mixing bowl (non-metallic)
* Applicator brush
* Gloves (non-latex)
* Old towel (that you don't mind staining)
* Hair clips
* Timer
* Shampoo and conditioner (preferably color-safe and moisturizing)
* Optional: Olaplex or a similar bond-building treatment (to minimize damage)
* Vaseline or barrier cream
5. Don't Wash Your Hair: Leave your hair unwashed for 1-2 days before bleaching. The natural oils help protect your scalp.
6. Protect Your Skin: Apply Vaseline or a barrier cream to your hairline, ears, and neck to prevent the bleach from irritating your skin.
7. Work in a Well-Ventilated Area: Bleach fumes can be strong.
III. The Bleaching Process (Step-by-Step)
1. Mix the Bleach: Follow the instructions on the bleach powder and developer packaging. A common ratio is 1:2 (1 part bleach powder to 2 parts developer), but check the specific instructions for your products. Mix thoroughly until you have a smooth, creamy consistency.
2. Section Your Hair: Divide your hair into four sections (or more, depending on its thickness). Clip each section out of the way.
3. Apply the Bleach: Start applying the bleach mixture about 1/2 inch away from your scalp (roots process faster due to body heat). Work your way down the hair shaft, saturating each strand evenly. This is important to prevent banding.
4. Process the Roots: Once you've applied the bleach to the rest of your hair, go back and apply it to the roots.
5. Monitor Carefully: Check the hair every 5-10 minutes. The strand test will give you an idea of how quickly your hair lifts.
6. Don't Exceed the Maximum Processing Time: The maximum processing time is usually 50 minutes but check the box of the bleach you purchased. Leaving the bleach on too long will cause excessive damage.
7. Rinse Thoroughly: Once your hair has reached the desired level of lift (or the maximum processing time is up), rinse it thoroughly with cool water. Make sure all the bleach is removed.
8. Shampoo and Condition: Use a color-safe shampoo and a moisturizing conditioner.
9. Apply Toner (If Necessary): If your hair is too yellow or orange, apply toner according to the product instructions. Toner should be applied to damp hair. Rinse after the directed time.
10. Deep Condition: Use a deep conditioner or hair mask to help restore moisture and strength.
11. Dry and Style: Let your hair air dry as much as possible. Avoid heat styling for a few days.
IV. Important Considerations and Risks
* Hair Type and Condition: Fine, damaged, or chemically treated hair is more susceptible to damage from bleaching.
* Dark Hair: Bleaching dark hair often requires multiple sessions to achieve a light blonde color. It's better to do it gradually to minimize damage.
* Banding: This is when the roots are lighter than the rest of the hair. It's caused by uneven application or processing.
* Overlapping: Avoid overlapping bleach on previously bleached hair, as this can cause breakage.
* Scalp Sensitivity: Bleach can irritate the scalp. If you experience burning or severe itching, rinse immediately.
* Hair Elasticity: Check your hair's elasticity by gently stretching a wet strand. If it breaks easily, your hair is damaged.
* Protein Treatments: Avoid doing protein treatments too soon after bleaching, as it can make the hair brittle.
V. Aftercare
* Moisturize, Moisturize, Moisturize: Use deep conditioners, hair masks, and leave-in conditioners regularly.
* Use Color-Safe Products: These are designed to protect your color and prevent fading.
* Limit Heat Styling: Heat can further damage bleached hair.
* Protect Your Hair from the Sun: UV rays can fade color and damage hair.
* Regular Trims: Get regular trims to remove split ends.
VI. When to See a Professional
* If you have dark hair and want to go very light blonde.
* If you have previously chemically treated hair (e.g., permed, relaxed, or colored).
* If you're unsure about any part of the process.
* If you experience any scalp irritation or burning during the bleaching process.
* If you want a complex color or highlighting technique.
* If you're simply not comfortable doing it yourself.
In conclusion, bleaching hair at home is a risky undertaking. Thorough research, careful planning, and a healthy dose of caution are essential. When in doubt, consult a professional stylist.
