FAQs 

1 - What is this conditioner and who should use it?

• It’s a strengthening conditioner formulated for hair that needs support to grow longer — ideal for clients with breakage, weak lengths, or hair that struggles to maintain length.

• Good for all hair types — especially those that are chemically treated, frequently styled with heat, or prone to split ends and breakage. 

2 - What benefits does it provide?

• Helps fortify hair from root to tip, strengthening strands so they’re less likely to break. 

• Supports longer, healthier hair growth by reducing breakage — when used as part of the full system (shampoo + conditioner + leave-in/treatments). 

• Conditions and softens the hair — makes it easier to detangle and manage, improving overall texture and sheen. 

• Helps prevent and minimize appearance of split ends and brittleness when regularly used. 

3 - How should it be used (salon or at-home)?

1. After shampooing (preferably with matching Extreme Length Shampoo), apply the conditioner to wet hair, focusing on mid-lengths to ends (and roots if needed). 

2. Leave on for a couple minutes to allow the formula to condition and strengthen strands, then rinse thoroughly. 

3. For best results and long-term hair health: follow the full Extreme Length routine (shampoo → conditioner → leave-in or treatment as needed) to maximize strength and minimize breakage. 

4 - Will it weigh hair down or interfere with styling?

• Not generally — the formula is described as lightweight, so hair remains soft and manageable rather than heavy or greasy. 

• For fine hair or hair prone to heaviness, stylists may recommend a lighter amount or focusing conditioner on mid-lengths/ends to ensure volume remains.

5 - Why choose this conditioner instead of a regular one?

• Because it’s specifically designed to strengthen and protect lengths — not just condition — it helps hair retain growth rather than constantly breaking. 

• When part of the full system, it supports significantly less breakage — which means clients can realistically reach longer lengths while keeping hair healthy.

• Makes a strong service-and-retail offer: for clients aiming for length retention and healthy growth, this conditioner is a salon-grade, maintenance-friendly solution that supports long-term hair goals.
