I. Pre-Treatments (Before Lightening): Preparing the Hair
The goal of pre-treatments is to strengthen the hair, balance porosity, and protect it from damage during the lightening process.
* Why Use Pre-Treatments?
* Strengthening: Lightening weakens the hair's protein structure (keratin). Pre-treatments infuse protein and other strengthening ingredients to make the hair more resilient.
* Balancing Porosity: Damaged hair is often porous, meaning it absorbs moisture unevenly. This can lead to patchy color and increased damage during lightening. Pre-treatments help even out the porosity, promoting even color lift.
* Protecting the Scalp: Lightening can irritate the scalp. Pre-treatments create a barrier to minimize discomfort.
* Minimize damage: Strengthening the hair before the chemical process will decrease the level of damage.
* Types of Pre-Treatments:
* Protein Treatments:
* How they work: Fill in gaps in the hair's cuticle with proteins (keratin, collagen, etc.).
* When to use: Especially beneficial for dry, damaged, or chemically treated hair.
* Examples: Products labeled "protein treatment," "keratin treatment" (not the straightening kind), or those containing amino acids.
* Moisturizing Treatments:
* How they work: Add hydration to dry, brittle hair.
* When to use: If the hair is dry, brittle, and lacks elasticity.
* Examples: Deep conditioners, hair masks with humectants (glycerin, honey) and emollients (oils, butters).
* Bond Builders (Pre-Lightening):
* How they work: These products are designed to protect and strengthen the hair's internal bonds during the lightening process. They help prevent breakage and reduce damage. They rebuild disulfide bonds in the hair.
* When to use: All the time when lightening hair.
* Examples: These are *added to* the bleach mixture. Olaplex No. 1 (used in-salon), Wellaplex No. 1, Schwarzkopf Fibreplex No. 1, Redken Flash Lift Bonder Inside.
* Scalp Protectors:
* How they work: Create a barrier between the bleach and the scalp, reducing irritation and sensitivity.
* When to use: If you have a sensitive scalp or are prone to irritation.
* Examples: Specialized scalp protector products, or even a light coating of coconut oil on the scalp.
* Clarifying Shampoo (Use carefully):
* How they work: Removes product buildup, minerals, and impurities that can interfere with lightening.
* When to use: If the hair has significant buildup. Important: Don't use a clarifying shampoo immediately before lightening. It can strip the hair too much and make it more vulnerable. Use it 1-3 days before the lightening service.
* How to Use Pre-Treatments:
* Protein Treatments: Follow the product instructions. Generally, apply to clean, damp hair, leave on for the recommended time (usually 10-30 minutes), and rinse thoroughly. Avoid overusing protein treatments, as this can make the hair brittle.
* Moisturizing Treatments: Apply to clean, damp hair, leave on for 15-30 minutes (or as directed), and rinse thoroughly. You can use heat (a warm towel or hair steamer) to enhance penetration.
* Bond Builders (Added to Lightener): Follow the specific instructions for the bond builder product. They are mixed directly into the bleach formula.
* Scalp Protectors: Apply to the scalp before applying the bleach.
* Timing: Ideally, start incorporating pre-treatments into your routine several weeks before lightening. A deep conditioning treatment once a week can make a big difference.
II. Post-Treatments (After Lightening): Repairing and Maintaining
The goal of post-treatments is to repair damage, replenish moisture, and maintain the color.
* Why Use Post-Treatments?
* Repair Damage: Lightening weakens the hair's protein structure and cuticle. Post-treatments help rebuild and strengthen the hair.
* Replenish Moisture: Lightening can dry out the hair. Post-treatments add hydration and improve elasticity.
* Seal the Cuticle: A closed cuticle helps retain moisture and color, making the hair smoother and shinier.
* Tone the hair: Lightened hair often needs to be toned to achieve the desired shade.
* Types of Post-Treatments:
* Bond Builders (Post-Lightening):
* How they work: Continue to rebuild broken disulfide bonds and strengthen the hair's internal structure.
* When to use: Immediately after rinsing the bleach and after toning.
* Examples: Olaplex No. 2, Wellaplex No. 2, Schwarzkopf Fibreplex No. 2, Redken Acidic Bonding Concentrate.
* Deep Conditioners/Hair Masks:
* How they work: Provide intense hydration and nourishment.
* When to use: Regularly, especially in the first few weeks after lightening.
* Examples: Masks with ingredients like shea butter, coconut oil, argan oil, and hyaluronic acid.
* Protein Treatments:
* How they work: Rebuild the hair's protein structure.
* When to use: If the hair feels weak or brittle. Use sparingly, as overuse can lead to brittleness.
* Acidic Shampoos and Conditioners:
* How they work: Help to close the hair cuticle, which is opened during the lightening process. A closed cuticle helps to retain moisture, color, and shine.
* When to use: Every time you wash your hair.
* Examples: Look for shampoos and conditioners with a pH of 4.5-5.5. The Redken Acidic Bonding Concentrate line is excellent.
* Leave-In Conditioners/Heat Protectants:
* How they work: Provide ongoing hydration, detangling, and protection from heat styling.
* When to use: After every wash, before heat styling.
* Hair Oils/Serums:
* How they work: Add shine, smooth frizz, and protect the hair from environmental damage.
* When to use: On damp or dry hair, as needed.
* Toners:
* How they work: Neutralize unwanted tones (yellow, orange) and achieve the desired shade.
* When to use: Immediately after lightening and as needed to maintain the color.
* Purple Shampoo/Conditioner:
* How they work: Neutralize yellow tones in blonde hair.
* When to use: Once or twice a week to maintain blonde tones. Overuse can lead to a purple tint.
* How to Use Post-Treatments:
* Bond Builders (Post-Lightening): Apply after rinsing the bleach and before shampooing. Leave on for the recommended time (usually 10-20 minutes), then rinse and follow with shampoo and conditioner.
* Deep Conditioners/Hair Masks: Apply to clean, damp hair, leave on for 15-30 minutes (or as directed), and rinse thoroughly.
* Protein Treatments: Apply to clean, damp hair, leave on for the recommended time, and rinse thoroughly.
* Acidic Shampoos and Conditioners: Use as your regular shampoo and conditioner.
* Leave-In Conditioners/Heat Protectants: Apply to damp hair before styling.
* Hair Oils/Serums: Apply a small amount to damp or dry hair, focusing on the ends.
* Toners: Apply to damp hair, follow the instructions carefully, and rinse thoroughly. Watch the hair closely during processing to avoid over-toning.
* Purple Shampoo/Conditioner: Use once or twice a week, alternating with your regular shampoo and conditioner.
III. Important Considerations
* Hair Type and Condition: The specific pre- and post-treatments you need will depend on your hair type (fine, medium, coarse), porosity, and existing condition.
* Professional Advice: Consult with a professional hairstylist for personalized recommendations, especially if you're new to lightening your hair.
* Patch Test: Always do a patch test before using any new product to check for allergies or sensitivities.
* Less is More: Avoid overloading the hair with too many products, which can lead to buildup.
* Quality Products: Invest in high-quality products specifically designed for color-treated hair.
* Listen to Your Hair: Pay attention to how your hair feels and adjusts your routine accordingly. If it feels dry, use more moisturizing treatments. If it feels weak, use protein treatments.
* Regular Trims: Get regular trims to remove split ends and prevent further damage.
* Minimize Heat Styling: Heat styling can further damage lightened hair. Use heat protectants and try to air dry whenever possible.
* Be Patient: It takes time to repair damaged hair. Be consistent with your pre- and post-treatment routine, and you'll see improvements over time.
In summary:
* Before Lightening: Strengthen, balance porosity, protect the scalp, and use bond builders.
* After Lightening: Repair damage, replenish moisture, seal the cuticle, tone the hair, and maintain the color with appropriate products.
By following these guidelines, you can help minimize damage, keep your hair healthy, and enjoy your beautiful lightened hair. Good luck!
