FAQ 

Q: What is 4Bond MBC used for?
A: The 4Bond MBC is a bond-building / hair repair treatment designed to repair internal, broken or damaged hair bonds — working from the inside out to strengthen the hair cortex and cuticle, restore integrity after chemical or heat damage, and improve hair strength, elasticity and manageability. 

Q: What hair types or hair conditions benefit most from it?
A: It’s especially beneficial for hair that is damaged, weakened, brittle, color-treated, bleached, heat-styled, chemically processed, or frequently exposed to chemicals (e.g. color or lightening). It works across hair textures — fine to coarse, straight to curly — whenever hair bonds have been stressed or compromised. 

Q: What are the key ingredients / formula features — and why do they matter?
A: The treatment uses a proprietary bond-building blend including:

• Polymers — to coat, condition, and align hair strands, improving manageability and gloss. 

• Hydrolyzed Keratin Amino Acids — to help replenish lost keratin in damaged hair cuticles, repairing structural damage and reducing breakage. 

• Hydrolyzed Quinoa Protein & Baobab Protein — rich in amino acids, which help strengthen the hair from within, improve elasticity, and add moisture, softness and resilience. 

• Additional nourishing extracts (e.g. seaweed, aloe, botanical extracts) — contributing moisture, scalp nourishment, and overall hair health. 

Together, these ingredients work to penetrate the cortex, seal into the cuticle, and rebuild internal damage — not just surface-level smoothing, giving more durable results than a standard conditioner or mask. 

Q: What results can clients expect after using it properly?
A: With correct use, clients should notice:

• Stronger, more resilient hair — less breakage, fewer split ends, improved hair integrity.

• Improved softness, shine and manageability — hair becomes easier to detangle and style, feels smoother and healthier.

• Better elasticity and reduced brittleness — hair recovers from chemical or thermal damage and withstands future styling better.

• Longer-lasting results — because bonds are rebuilt internally, the benefits are more durable than surface-level conditioning.

• Improved performance during chemical services or heat styling — hair is more resistant to damage and retains health better through treatments.

Q: How should 4Bond MBC be used / applied for best results?
A: There are several ways to use it, depending on need: 

• Standalone treatment: Use MBC on its own (no color/lightener needed), apply to hair thoroughly (follow instructions), process as directed to repair hair bonds. 

• With chemical services (coloring, lightening, relaxing, perms, smoothing, straightening): Add the recommended amount of MBC directly to the service mixture — this helps protect and repair hair during chemical processing, without needing to change formulation or processing time. 

• After the chemical service — follow with gentle care (bond-safe shampoo/conditioner) and minimize harsh heat or treatments to let the bonds rebuild and stabilize.

Q: Is 4Bond MBC safe for color-treated, chemically processed, or textured hair?
A: Yes — 4Bond MBC is specifically designed for damaged, color-treated, bleached, relaxed or heat-styled hair. Because it rebuilds internal bonds and strengthens the hair structure from within, it supports hair health rather than damaging or stripping it.
