FAQ 

Q: What is 4Bond ProExtend used for?
A: 4Bond ProExtend is a salon-service extender / maintenance spray / leave-in treatment designed to seal the hair cuticle, repair split ends and reinforce hair bonds — especially after chemical services like coloring, lightening, smoothing, straightening, or heavy heat styling. 

Q: What hair types or hair conditions benefit most from it?
A: It’s beneficial for color-treated, chemically processed, heat-styled, or otherwise damaged hair — including fine, medium, or coarse textures. It helps maintain integrity and extend the life of salon services, making it ideal for clients who frequently bleach, color, straighten, or heat-style hair. 

Q: What are the key features / formula benefits — and why do they matter?
A: - Bond-building complex: Uses a blend of polymers, keratin amino acids, quinoa and baobab proteins rich in amino acids to penetrate the hair’s cortex, helping to repair internal bond damage and strengthen the hair shaft. 

• Cuticle sealing & split-end repair: Helps seal the cuticle layer and minimize split ends or breakage that result from chemical or thermal services — contributing to smoother, stronger hair. 

• Service longevity & maintenance: Designed as a “salon-service extender,” it helps hair maintain results longer — sustaining smoothness, strength, and gloss from treatments like smoothing, straightening or coloring.

• Improved manageability, softness & shine: The conditioning proteins & polymers help improve softness, manageability, gloss and overall hair health — making hair easier to style and less prone to damage or frizz between salon visits. 

Q: What results can clients expect after using it properly?
A: With consistent use (especially after chemical or heat services), clients may notice:

• Stronger, less brittle hair with reduced split ends and breakage.

• Hair that stays smoother, shinier, and more manageable — even between washes or styling sessions.

• Longevity of salon treatments: color, smoothing, straightening — maintenance of results for longer.

• Easier styling, less frizz or damage, and improved overall hair health over time.

Q: How should 4Bond ProExtend be applied for best results?
A: - On damp hair: mist evenly in sections after shampooing or after a chemical/thermal service, then style as usual — do not rinse out. 

• On dry hair: you can also mist before using heat tools (flat-iron, blow-dryer) — helps maintain bond integrity and protect hair from further damage. 

• Use as part of a maintenance routine to extend the life of salon services — especially after color, bleach, smoothing or straightening treatments. 

Q: Is it safe for color-treated, chemically processed, or heat-styled hair?
A: Yes. 4Bond ProExtend is part of the 4Bond bond-building line — specifically formulated to repair and reinforce hair bonds damaged by coloring, bleaching, straightening, or thermal styling. It is intended for treated hair and helps maintain hair health even with frequent styling or salon services.
