Supersize Fortifying Shampoo That Repairs and Strengthens Damaged Hair

Joico InnerJoi Strengthen Shampoo in the supersize 1L format is a naturally inspired fortifying shampoo designed for overworked and damaged hair that needs genuine repair and strengthening from the very first step of the wash routine. Part of the InnerJoi Strengthen collection, it creates a rich, gentle lather that nourishes and revitalises while actively reducing breakage and repairing damage caused by heat styling, chemical services and everyday wear. With 90%+ naturally derived ingredients, it is a clean, considered choice for damaged hair care. Find it alongside other sulphate-free shampoos in our full range.

Coconut Oil and Abyssinian Oil for Deep Repair and Protection

Two naturally derived oils sit at the heart of the InnerJoi Strengthen formula. Coconut Oil is a time-honoured superfood ingredient that penetrates the hair shaft to nourish and reduce protein loss — one of the primary causes of breakage in damaged hair. Abyssinian Oil is a nutrient-rich, antioxidant-packed oil that strengthens and conditions while being produced with low water requirements, making it an eco-friendly choice that performs as well as it sits on the planet. Together they repair the damage that is already present while protecting against future breakage with every wash.

Vegan Protein and Olive Ester for Strength and Shine

Vegan Protein derived from peas and vegetables mimics the natural proteins found in healthy hair, rebuilding structural resilience in strands that have been weakened by damage over time. Olive Ester, a biodegradable ingredient sustainably sourced from olive oil production, supports healthy, shiny hair while keeping the formula's environmental credentials as strong as its performance. The result is hair that feels noticeably stronger, softer and more vibrant with every wash — with a natural movement and shine that damaged hair often loses entirely. For best results use alongside the Joico InnerJoi Strengthen Conditioner as part of a complete naturally derived repair routine.

How to Use Joico InnerJoi Strengthen Shampoo

Apply a generous amount to wet hair and massage into a rich lather from roots to ends. Rinse thoroughly and follow with Joico InnerJoi Strengthen Conditioner for a complete repair and strengthening routine. Suitable for daily use on damaged, dry or chemically processed hair. Also available in the 300ml size for everyday home use.
