Oligo Pro Porosity Equalizer 240ml
Nothing beats hitting your target shade right on the nose - especially after a pre-lightening service, which creates an absorbent (porous) canvas to tone.
Directions: The Porosity Equalizer will tip the predictability scale in your favour. Simply spray a small amount onto towel-blotted hair and leave in to ensure even, balanced colour results from scalp to ends every time.
Pro tip for perms! Spray the Porosity Equalizer before wrapping permanent wave rods to prevent dryness!
