FAQ 

Q: What is this product used for?
A: The StraightLines treatment is a professional keratin-protein / bond-building smoothing and straightening system designed to eliminate frizz, deeply smooth hair, realign hair structure for straighter hair, and improve manageability and shine. 

Q: What hair types or hair conditions benefit most from it?
A: It works on virtually all hair types — including virgin, chemically treated, textured, curly, wavy, coarse, or natural hair. It's especially suited for hair that is frizz-prone, unruly, curly, or difficult to manage, and for clients who want long-lasting straightening + smoothness, even on chemically treated or color-treated hair. 

Q: What are the key features / formula benefits — and why they matter?
A:

• Bond-building / “Nanoplasty” technology: StraightLines uses an advanced 4Bond complex — a blend of polymers, keratin, quinoa & baobab proteins rich in amino acids — that penetrates the hair’s cortex to repair internal bonds, strengthen strands, and realign hair structure for straightness. 

• Formaldehyde-free & plant-based formula: Unlike traditional harsh straighteners, this treatment avoids formaldehyde/aldehyde — meaning less risk of irritation and safer for color-treated or chemically-processed hair. 

• Long-lasting smoothing & anti-frizz effect: Depending on hair type and maintenance, results can last up to 5 months — hair remains smooth, frizz-free, easy to manage, and straighter over time. 

• Improved shine, softness, manageability and easier detangling: After treatment hair tends to be more aligned, with sealed cuticle — making hair feel softer, smoother, easier to comb or brush, and less prone to tangling or damage. 

Q: What results can clients expect after using it properly?
A: Clients can expect:

• Smooth, straight or smoothened hair with significantly reduced frizz and fly-aways.

• Longer-lasting smoothness and manageable hair — easier to style and maintain between washes.

• Improved hair strength and health — due to bond-repairing proteins and internal strengthening, reducing breakage and split ends over time.

• Shiny, soft, sleek hair — with improved texture and appearance, even on previously curly or coarse hair.

Q: How is the StraightLines treatment applied (salon-service)?
A: According to manufacturer instructions: 

1. The hair must first be deep-clarified / double-shampooed to remove build-up.

2. Hair is towel-dried or partially dried, then treatment is applied section by section from roots (leaving small gap from scalp) to ends, combed through to ensure even distribution. Use about ½ oz per 15 inches of hair.

3. After application, hair is blow-dried until 100 % dry, then flat-ironed in small subsections (1/8") at the recommended temperature (typically 193-210 °C / 380-410 °F, though fine hair may need fewer/milder passes) to seal the treatment. 

4. For best results, hair should not be washed for at least 24 hours post-treatment. 

Q: Is this treatment safe for color-treated, chemically processed, or natural textured hair?
A: Yes — StraightLines is designed to be formaldehyde-free, plant/protein-based, and gentle enough for sensitive or treated hair, making it suitable for color-treated, bleached, relaxed, textured, or natural hair while still delivering smoothing, strength, and frizz-control.
