Compare the 5L Wild Rose Shampoo refill with the standard 400ml bottle to decide which size fits your hair, household, and storage.
Quick answer
The 5L Wild Rose Shampoo refill is the better buy for households with multiple people or anyone who already knows they like the Wild Rose formula. Choose the 400ml bottle if you have limited storage, want to test the scent first, or prefer a smaller bottle for travel. Both sizes share the same 99.5% natural origin formula for normal hair and scalp.
What the 5L refill actually gives you
The 5L Wild Rose Shampoo is a single large refill bottle designed for normal hair and scalp. It uses the same formula as the smaller size: 99.5% natural origin, free from parabens, SLS and silicones, with organic wild-harvested rosehip oil and rose centifolia oil. The rosehip oil is zero waste, which means the whole fruit is used rather than just the seed. Because it is a refill, you will need a smaller bottle or dispenser to decant into for daily use. The 5L size is not designed to sit in the shower; it is a bulk supply you store and pour from.
What the 400ml bottle gives you
The 400ml Wild Rose Shampoo is the standard retail size. It is the same formula, but in a bottle that is easy to hold, store on a shower shelf, and take to the gym or on holiday. It costs more per millilitre than the 5L refill, but it lets you try the scent and formula without committing to a large volume. If you have never used Wild Rose before, the 400ml is the lower-risk starting point.
Cost per wash and storage trade-offs
The 5L refill has a lower cost per millilitre, so the more you wash your hair, the more the bulk size saves you. But that saving only matters if you will use it before it goes off and if you have somewhere cool and dark to store it. A 5L bottle is heavy when full and takes up roughly the space of a small suitcase. The 400ml bottle is lighter, easier to handle, and fits almost anywhere. If you share a bathroom with limited shelf space, the smaller bottle may be the more practical choice even though it costs more per wash.
How to decide based on your household
Count the people who will use it and how often they wash their hair. One person washing daily will take months to finish 5L. Two or three people washing every other day will get through it faster. If you already use other Wild Rose products, such as the Wild Rose body wash, you know the scent suits you, so the 5L refill is a safe bulk buy. If you are new to the range, start with 400ml and see how your scalp responds.
Trade-offs: 5L refill vs 400ml bottle
- Upfront cost vs cost per wash: The 5L refill costs more upfront but works out cheaper per millilitre. The 400ml bottle costs less upfront but more per wash. If you wash your hair often and will use it within a reasonable time, the 5L saves money.
- Storage and handling: 5L is heavy and needs a cool, dark storage spot plus a smaller bottle for daily use. 400ml fits on a shower shelf and is easy to travel with. Limited bathroom space or no decanting bottle? Choose 400ml.
- Trying the formula: Both sizes use the same formula for normal hair and scalp. The 400ml lets you test the scent and how your scalp responds before committing to 5L. New to Wild Rose? Start with 400ml; if you already know the range, go for 5L.
