Care additive! One of my fave tools when colouring using @labiosthetiqueuk is care additive. Citric acid reduces the ammonia levels in your formulation and slows down the deposit, while adding tons of nourishment. A little hack. When I have root colour left over and I want to refresh the mids and ends, I will top up with my formulation with care additive. This will reduce the PH and slow the deposit. Perfect for a quick refresh without wasting any tint or worrying about the ends sucking up product and going darker! #careadditive #labiosthetique #labiosthetiqueparis #labiosthetiquecolor #labiosthetiqueuk #tintandtone #tintandtoneadvanced #radianthairgloss
