FAQs 

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

• A strengthening shampoo formulated to support hair growth, ideal for clients dealing with breakage, split ends, or slow-growing hair.

• Suitable for all hair types, especially those that are fragile, regularly styled or chemically treated, or prone to breakage when growing out.

2 - What benefits does it provide?

• Gently cleanses while strengthening hair fibers, helping reduce breakage and encouraging healthier growth.

• Helps improve manageability, softness and shine — making hair easier to detangle and style as it grows.

• Prepares hair for additional treatments (conditioner, mask, leave-in) by cleansing buildup and opening the hair fiber for nourishment.

• Can help maintain hair integrity during growth phases, reducing loss from damage, split ends, or brittleness.

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

1. Apply to wet hair, massage through scalp and hair from roots to ends, then rinse thoroughly.

2. Use regularly — with frequency depending on client’s hair type, styling habits, and hair-growth goals.

3. Follow with a compatible conditioner or treatment (especially when hair is damaged or chemically treated) for best strength and growth support.

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

• Typically no — formulated to cleanse and strengthen without heavy buildup, so hair remains soft, light, and styling-ready.

• On very fine or low-density hair, stylists may recommend moderating use (or pairing with a lighter conditioner) to avoid potential flattening.

5 - Why choose this shampoo instead of a regular shampoo?

• Specifically engineered for growth support + fiber strengthening + breakage reduction, not just cleansing — giving added value for clients trying to grow their hair long and healthy.

• Helps maximize return on salon-grade maintenance and styling services by protecting hair integrity during growth.

• Offers a strong “health + growth” care narrative — appealing for clients focused on length retention, strength, and long-term hair goals.
