Bond Serum is a damage-repairing leave-in treatment that is applied to damp hair. Uniquely formulated with our exclusive ProTarget Technology™, it delivers concentrated repair and heat protection with a velvety lightweight texture.

Bond Serum is ideal for anyone who prioritizes the health and well-being of their hair and/or whose hair is: 

• chemically treated (e.g., colored, bleached, relaxed or permed)
• heat-damaged from frequent use of styling tools like flat irons or curling irons
• frizzy
• dry 

Enhance the repair benefits of Bond Serum by applying after cleansing with Bond Boost for New Wash.

1. Start with clean, damp hair. 
2. Shake the bottle before using and apply to the most damaged areas of your hair, then work through from roots to tips. Use a dime-size amount for fine hair and quarter-size for thicker hair, adding more if needed. Do not rinse out. 
3. Let it sit and penetrate your hair before continuing with your regular styling routine.

Yes, you can use Bond Serum every day! Just make sure you use it on damp hair.

ProTarget Technology™ is our exclusive double repair efficacy complex that combines cuticle-nourishing nutrients and a clinically proven bond-restoring complex that fortifies hair from within. It delivers twice the recovery benefits of other hair repair treatments, healing and preventing compromised areas like split ends, breakage and frizz. 

ProTarget Technology™ delivers double repair efficacy—meaning it heals hair inside and out—thanks to its unique formulation with liposome technology that offers these benefits:

• Targeted delivery and enhanced penetration: ProTarget Technology™ consists of liposomes, which are tiny sphere-shaped particles that can encapsulate active ingredients like vitamins, antioxidants or other beneficial compounds. Liposomes in ProTarget Technology™ encapsulate specific active repair ingredients like panthenol and ceramides, allowing for targeted delivery and enhanced penetration. This is particularly beneficial in hair repair because it enables the delivery of reparative or nourishing substances directly to damaged areas of the hair.
• Protection of active ingredients: Liposomes provide a protective barrier around active ingredients, shielding them from external factors that could degrade their effectiveness. 
• Longer-lasting results: The controlled release of active ingredients from liposomes allows for a sustained and gradual release over time. This can result in longer-lasting effects compared to products without liposome technology.

Yes! ProTarget Technology™ targets hydrogen, salt and disulfide bonds in the hair by addressing the moisture, pH balance and structural integrity. This promotes an overall healthy appearance and manageability of the hair.

Hydrogen bonds are formed between the hydrogen atoms of one amino acid and the electronegative oxygen of another; they are typically affected by water and heat temporarily. Hydrating ingredients in Bond Serum that attract moisture to the hair include panthenol, betaine, glycerin and propanediol.

Salt bonds are formed by the negative and positive charged portions of the amino acids in the hair; they are the most stable, at an acidic to neutral pH. Bond Serum is formulated at an effective pH and buffered with citric acid to maintain the natural pH of healthy hair to stabilize these bonds.

Disulfide bonds are formed between cysteine amino acids and are the strongest bonds in the hair. They contribute significantly to the hair’s structural integrity and strength. Disulfide bonds are affected by using products with an acidic pH to prevent swelling and damage that can occur at higher pH levels, and ProTarget Technology™ helps repair and maintain these important bonds.

No. Protein overload is caused by products that contain a large amount of hair protein in their formula. Bond Boost contains only <1% arginine in its formula to synergistically work with other actives to strengthen the hair, decrease hair breakage, minimize hair loss, moisturize and (for those who color their hair) protect from the damaging effects of bleach.

Yes! Bond Serum offers heat protection up to 450°F.
