Patchouli and ylang ylang combine in Osmo's Deep Moisture formula to deliver a healthy scalp and incredibly smooth hair. They're backed up by intensely moisturising panthenol (provitamin B5) to repair dry and damaged hair and create superb softness and silkiness.

The Deep Moisture Duo twin pack features a 1-litre bottle of Deep Moisture shampoo and a litre of the matching conditioner and is fantastic value, coming in around 25% cheaper than the cost of buying both separately. Of course, at that price it's not only great for your salon, but makes a profitable retail product too.
