Bond Repair
172 productsBond-Repair Treatments for Damaged, Bleached & Over-Processed Hair
Bond repair is the technology that transformed professional hair care over the last decade. Hair is held together by disulfide bonds inside the cortex — and bleach, color, heat, and harsh chemistry break those bonds. When too many break, hair turns gummy when wet, snaps when dry, and refuses to hold shape.
Bond builders restore the connections. Olaplex pioneered the category with its patented bis-aminopropyl diglycol dimaleate molecule, but the field has expanded fast — L'Oréal's Smartbond, Joico's Defy Damage, Goldwell's StrandFire, KMS Moist Repair, Schwarzkopf's Fibre Clinix and BlondMe Bonding, and Matrix Total Results all bring different chemistry to the same goal: rebuild the bonds and give damaged hair its elasticity back.
ProHair carries the full professional spectrum — in-salon treatments, take-home masks, shampoos, conditioners, and leave-ins. If you've bleached, balayaged, double-processed, or fried your hair with heat, this is where you start.

Frequently Asked Questions
What's the difference between bond repair and protein treatments?
Protein treatments (keratin, hydrolyzed wheat) deposit protein into the cuticle to temporarily fill gaps. Bond repair (Olaplex, Smartbond, BlondMe Bonding) uses smaller molecules that penetrate to the cortex and re-link the actual disulfide bonds. Most damaged hair benefits from both — protein for structure, bond repair for elasticity.
How often should I use Olaplex No.3?
Once a week for moderately damaged hair, twice a week if you're heavily bleached or chemically processed. Apply to damp hair, leave at least 10 minutes (or longer — it doesn't over-condition), then shampoo and condition normally.
Will bond repair work on hair that's already gummy or stretchy?
Olaplex No.0 + No.3 in combination is the strongest at-home protocol. For severely compromised hair, an in-salon bond service (Olaplex Stand Alone, L'Oréal Smartbond) is more effective. If hair stretches and stays stretched, the cortex is heavily compromised — controlled trims may be needed alongside repair.
Can I use bond-repair products if my hair is virgin or healthy?
Yes — bond builders won't damage healthy hair. Many people use them prophylactically before color or heavy heat styling. Olaplex No.6 and No.7 in particular are great daily products for any hair type.
Is Olaplex really patented? Are the dupes any good?
Yes, Olaplex's bis-aminopropyl diglycol dimaleate molecule is patented through 2030. Other brands (L'Oréal Smartbond, Schwarzkopf BlondMe Bonding) use different patented chemistry. They work — they're just different molecules. We carry both.
Should I use bond repair or moisturizing products on my damaged hair?
Both. Damage breaks bonds AND degrades the cuticle's ability to hold moisture. A complete routine includes bond repair (1-2x weekly), strengthening treatments, AND deep moisturizing masks. Joico K-PAK Color Therapy and Moisture Recovery used together is a classic example.
Do you carry the in-salon professional sizes?
Yes — most brands have professional sizes available. Email prohairca@gmail.com for trade pricing if you're a licensed stylist.
How fast will I see results?
Elasticity improvements show within 1-2 uses of a proper bond treatment. Cuticle smoothing and full structural recovery take 4-6 weeks of consistent use. Severely damaged hair may take longer.
