Kerasys Repair

The Advanced Repair Ampoule line is KERASYS's most concentrated repair system. The name 'Ampoule' signals a formula inspired by skincare ampoules: a higher-concentration treatment approach than a standard rinse or conditioner. The line includes shampoos in 600ml, 750ml, and 1000ml, and treatments in 600ml and 1000ml. The 600ml sizes are practical for individual daily use, and the 1000ml provides better per-wash value for households with multiple users or high-frequency washing. The Advanced Repair Ampoule Shampoo is formulated to deliver repair actives during the cleansing step itself, not just through the treatment, which distinguishes it from most shampoos that focus only on cleansing.

The Advanced 10X Repair Ampoule Serum (80ml) is the standalone leave-on product in the Advanced Repair system. The '10X' designation indicates a formula with ten times the repair concentration compared to the standard Advanced Repair Ampoule formula. It is applied to the hair and scalp directly and left in without rinsing, functioning as a targeted treatment step added after the shampoo and treatment routine are complete. At 80ml it is a serum-sized product, and the application amount per session is small (a few drops to a thin film across the targeted areas). This format is most effective on the most structurally compromised sections of hair, such as bleached ends or repeatedly processed areas, where a higher-concentration leave-on treatment provides sustained repair between washes.

The Advanced Repair Water Treatment Pitch (220ml) is a rinse-off treatment in the Advanced Repair Ampoule line. 'Pitch' in this context refers to a pitch-black or dark-colored formula, common in Korean hair treatments that use activated charcoal, fermented ingredients, or dark plant extracts. At 220ml it is in the mid-size treatment format, larger than a travel size but not the full 600ml or 1000ml of the main treatments. It is applied after shampooing, left on for five to fifteen minutes, then rinsed, and is intended as an intensive treatment session rather than an everyday conditioning step.

Two Propolis Damage Repair products are available: the Shampoo (1000ml) and the Treatment (1000ml). Propolis in hair repair provides antimicrobial scalp support alongside hair conditioning, which distinguishes this line from the Advanced Repair Ampoule products that focus purely on structural hair repair. The Propolis Damage Repair line suits people who want both damage repair and scalp health support from the same product system. The 1000ml sizes of both products provide three to four months of daily use for one person, making them economical for long-term routine use.

The Clinic Damage Repair Shampoo (1500ml) sits at the intersection of the Damage Clinic and Advanced Repair systems, positioned for daily use at a high volume. At 1500ml it is sized above standard home bottles for households or heavy daily users. It provides the Clinic-level repair formula in a bulk format that reduces reorder frequency. For a single daily user, 1500ml lasts approximately two to three months. This size is practical for anyone who has settled on a KERASYS Clinic Damage Repair shampoo as a long-term daily product and prefers to buy less often.

The Advanced Repair Ampoule Treatment (600ml or 1000ml) is the rinse-off conditioning step used after every shampoo, following the same routine as any conditioner but with the concentrated Ampoule formula. It is rinsed after two to five minutes. The 10X Repair Serum (80ml) is the leave-on product applied after the entire wash routine is complete, concentrated on the most damaged areas and not rinsed. Using both in the same routine, Treatment during the wash and Serum after drying, creates a two-stage repair approach where the Treatment addresses the full hair shaft and the Serum delivers sustained intensive treatment to targeted areas between washes.

Both lines target damaged hair but differ in formula direction. The Advanced Repair Ampoule line uses a concentrated protein and ampoule-style formula for structural repair, suited for hair that has lost protein structure from bleaching or chemical processing. The Propolis Damage Repair line adds the antimicrobial and scalp-supporting properties of propolis alongside damage repair, making it the better choice for hair damage accompanied by scalp concerns. If the primary concern is purely hair shaft repair, the Advanced Repair Ampoule is more focused. If scalp health is also a priority, the Propolis Damage Repair line handles both.

A full Advanced Repair routine runs as follows. Wash: Advanced Repair Ampoule Shampoo (any size). Condition: Advanced Repair Ampoule Treatment, left on three to five minutes, then rinsed. Once or twice weekly: replace the Treatment with the Water Treatment Pitch (220ml), left on ten to fifteen minutes. After drying: apply a small amount of the 10X Repair Serum (80ml) to the most damaged sections of hair and leave in. This sequence covers every repair opportunity in the washing routine and adds a sustained leave-on treatment step for the most intensive care. The 10X Serum can be added daily or on the days most severe damage is noticed.
