Core Strength Shampoo

Protein-enriched shampoo for damaged or fine curls

✓CGM ApprovedStrengthContains ProteinStep: Cleanse

The Strength (purple) range's cleansing step — a protein-enriched sulphate-free shampoo with a patented strengthening active designed to work on the hair structure during the wash step rather than leaving all the repair work to treatments. Particularly useful for colour-treated, bleached, heat-damaged, or chemically processed curls that need structural support baked into every step of the routine. The Strength range broadly suits fine hair that loses definition with pure moisture products, or looser patterns (2a–3a) that snap during detangling. Pair it with the Bond Curl Rehab Salve for a complete repair-focused wash day.
