A complete at-home 4-step system with double-volume straightening agents for long, stubborn frizzy hair.
About this product
Built for long, stubborn curly hair, this Proqualite straightening set doubles the straightening agent volume (100g/100g) compared to the short-hair version, while keeping the same 4-step system: hot iron manicure for damage repair plus a 3-day Smooth Keep Essence for lasting humidity protection. Comes complete with a straightening comb and gloves.
How to use
- Apply Agent 1 from root to tip through all sections, comb straight, and leave for 5-15 minutes, then rinse thoroughly.
- Apply Agent 2 and leave for 15 minutes, then rinse.
- Apply the hot iron manicure treatment and use a flat iron to smooth, then rinse.
- Blow-dry while straightening hair sections.
- Apply Smooth Keep Essence to hair ends daily for 3 days after treatment.
Ingredients
- Thioglycolic Acid Salt (Agent 1, 100g) — quasi-drug straightening active that softens hair's internal bonds to allow reshaping.
- Sodium Bromate (Agent 2, 100g) — quasi-drug neutralizing/fixing active that resets hair bonds into a straight shape.
- Hot Iron Manicure Treatment (15g) — repairing treatment applied with heat styling to smooth the cuticle and add moisture.
- Smooth Keep Essence (5g x 3) — leave-in essence applied for 3 days post-treatment to block humidity and preserve straightness.
FAQ
How is this different from the short-hair version?
This long-hair set contains double the straightening agent (100g/100g vs 50g/50g) to fully cover longer hair lengths.
What's included in the box?
Agents 1 and 2, hot iron manicure treatment, 3 packets of Smooth Keep Essence, a straightening comb, and gloves.
How long does the straightening last?
Like salon straightening, results last until the treated hair grows out since the treatment changes the hair's internal bond structure.
