Biolage Colorlast Shampoo 400ml and 500ml Refill Duo Bundle
Biolage Colorlast Shampoo 400ml and 500ml Refill Duo Bundle pairs the 400ml shampoo with its matching 500ml refill in one convenient pack.
This duo is designed to keep your routine going without interruption. The 400ml bottle gets you started, and the 500ml refill tops it back up once it runs low, so you never run out mid-routine. Refilling the same bottle rather than buying a new one each time means noticeably less packaging, and the refill works out better value per ml.

I love the refill system—it saves money and reduces waste. The 400ml bottle works well for my daily use, and the 500ml refill lasts through several weeks. My hair feels clean and vibrant without any color fading.

The duo bundle is convenient and cost-effective. I switched from buying new bottles regularly and now just refill. The shampoo maintains my hair color well and doesn’t leave it feeling dry.

Great value for the price. The refill fits perfectly into the original bottle. I’ve used it for over two months and still have no issues with performance or smell. My hair stays soft and manageable.
