Bottle blondes, this shampoo will help keep cool tones (that include greys, ash blue etc.) salon-fresh for longer.

Pour this into your hand and you get a deep iodine blue shampoo that foams up easily. The true blue formula prevents the hair colour from turning brassy, especially for Asian hair with warm undertones. (Nothing I hate more than brassiness in light hair, makes the colouring job look cheap.)

I have done my research on O&M, and they are one of the few haircare brands that understand the intricate science of hair colouring, and the need for formulas that are not chemical laden.

Their products are always innovative and one-of-a-kind too.

In Singapore, O&M products are available in Sephora and selected stores.
