OSMO Deep Moisture Shampoo & Conditioner DUO 1000ml

OSMO Deep Moisture Duo: hydrating shampoo and conditioner for dry hair

The OSMO Deep Moisture duo brings the cleansing and conditioning stages together in one set. Designed for dry and damaged hair, the range helps replenish lost moisture without adding excess weight, leaving hair feeling softer, nourished and shiny. Use the bottles in sequence as part of your usual haircare routine.

Choose this pack when you need both products in the larger size. It makes it easy to restock the pair together, whether you are replacing bottles at home or purchasing for a salon wash station. Shampoo and conditioner have separate roles: wash with the shampoo first, then condition the lengths.

1000ml or 400ml: choosing your shampoo and conditioner size

• 1 x OSMO Deep Moisture Shampoo 1000ml: the cleansing step.
• 1 x OSMO Deep Moisture Conditioner 1000ml: the rinse-out conditioning step.

Each bottle holds 1 litre, giving you 2 litres across the duo. The 1000ml size is the volume of each product, rather than the combined amount. This listing is for the shampoo and conditioner set; a mask or leave-in treatment is a separate purchase.

Need just one replacement bottle? View OSMO Deep Moisture Shampoo or OSMO Deep Moisture Conditioner separately. Those pages also let you check smaller options, including 400ml bottles. Buying separately can suit a routine where one bottle runs out sooner than the other.

How to use your duo shampoo and conditioner

Gently massage the shampoo through wet hair and rinse thoroughly. Follow with conditioner on the mid-lengths and ends. Leave the conditioner for 3-5 minutes, then rinse well. Follow the directions on the bottles supplied if they differ.

Use each product for its own stage rather than mixing them together. The conditioner is a rinse-out product, so complete the final rinse before drying and styling. Adjust the amount used to your hair length and thickness; a 1000ml bottle is a pack size, not a single-use amount.

OSMO Deep Moisture shampoo and conditioner: price and haircare questions

Is this a 2-in-1 shampoo?

No. You receive two separate bottles, one shampoo and one conditioner. Use them one after the other.

Does 1000ml mean 1 litre in total?

No. This duo contains 1000ml of shampoo plus 1000ml of conditioner: 2 x 1 litre bottles.

Which hair type is the Deep Moisture range for?

It is intended for dry and damaged hair when hydration is a priority. If you are unsure which routine suits your hair, ask your hairdresser to help you choose.

Is this the same as the Deep Moisture mask?

No. A mask is a different product. This pack contains the two wash-day essentials shown above, with no additional treatment included.

Can I reorder only the conditioner next time?

Yes. The individual conditioner is listed separately at Mus & Co. Follow the link in the set contents section and choose the bottle size you need.

How can I compare the twin pack price?

For UK shoppers comparing value for money, check the current set price against buying two individual bottles in the same size. This pack supplies 2000ml in total. A shampoo and conditioner 400ml duo would supply 800ml, so compare the volume as well as the price shown. Delivery charges, where applicable, affect the final cost.

Is Deep Moisture a colour product?

This is a wash-and-condition haircare set. If your salon has recommended a particular routine after a colour service, confirm the range with your hairdresser before changing it.

Where can I check the ingredients?

OSMO describes its current duo as formulated with Pataua Oil and Keratin. The manufacturer lists Pataua Oil extract and Hydrolyzed Keratin in both products, with Panthenol in the shampoo. Read the ingredient list on each bottle you receive. The shampoo and conditioner are different formulas; check both labels if you avoid a particular ingredient.
