TSTADVANCE Japanese Hair Rebonding Kit — Permanent Crystallizing Straightener 1EX + Neutralizer for Very Resistant Hair, Brush Inc

TSTADVANCE Japanese Hair Rebonding Kit is a two-step permanent crystallizing straightener system formulated to relax and straighten very resistant hair, including a neutralizing cream and styling brush.

This professional-grade kit combines a concentrated straightening lotion (1EX) and a matching neutralizer (2) to restructure exceptionally resistant hair fibers into a smooth, straight finish. The formula is designed for long-lasting straight results when applied following the included directions, and the kit comes with a hair brush to help section and smooth hair during the process. It’s intended for experienced stylists or skilled at-home users who understand chemical straightening techniques.

How does the TSTADVANCE kit achieve permanent straightening?

The system uses a two-step chemical process: the straightening lotion breaks and reforms internal hair bonds to alter texture, and the neutralizing cream fixes the new structure to lock in straightness. When used correctly, the neutralizer halts the chemical action and restores the hair’s pH balance.

• Step 1: 1EX crystallizing straightening lotion reshapes resistant hair fibers.
• Step 2: Neutralizing cream (2) stabilizes and sets the new bond configuration.
• Includes hair brush to smooth and evenly distribute product during application.
• Best results achieved when following timing and heat guidelines for your hair type.

What should I expect during application and timing?

Application involves precise sectioning, even product distribution, and controlled processing time based on hair resistance. Over-processing risks damage, so adherence to timing charts and strand tests is essential before full-head application.

• Perform a strand test to determine ideal processing time for very resistant hair.
• Apply straightener uniformly from roots to ends, combing with the included brush for consistency.
• Rinse as instructed and apply neutralizer for the recommended duration to set the result.
• Follow post-treatment care: gentle sulfate-free shampoo and reduced heat styling initially.

How long will the straightening effect last and what maintenance is needed?

Results are long-lasting and can be considered permanent for the hair treated; newly grown hair will retain its natural texture and require touch-ups on the roots. Proper aftercare improves longevity and hair appearance over time.

• Permanent effect on treated lengths; touch-ups needed for new growth.
• Use moisturizing, protein-balanced treatments to maintain elasticity and shine.
• Avoid harsh sulfate shampoos and minimize excessive heat to preserve integrity.
• Professional toning or glossing can refresh shine after chemical straightening.

Is the TSTADVANCE rebonding kit safe for very resistant or previously treated hair?

The kit is formulated for very resistant hair types, but safety depends on hair history, prior chemical services, and correct application. A professional consultation and strand test are recommended when hair has been colored, bleached, or previously relaxed.

• Do a sensitivity and strand test before full application to check compatibility.
• Avoid applying to severely damaged or recently lightened hair without professional advice.
• If hair has multiple chemical treatments, consult a stylist for a customized approach.
• Follow neutralizer timing exactly to reduce risk of over-processing.

Who is this for: The TSTADVANCE Japanese Hair Rebonding Kit is aimed at experienced stylists and informed at-home users treating very resistant, coarse, or unruly hair who want a long-lasting straightening solution. It’s suitable for clients seeking a permanent straight texture on treated lengths while understanding that touch-ups on new growth and careful aftercare are required. If you’re uncertain about past chemical history or processing technique, consult a professional stylist before use.
