Bit of advice please. Client use to have KP 12.1. Then had bleach to go silver... had few times now decided to go back blonde coz of ‘upkeep’ of silver. Before decided to go back blonde used an ash on roots thinking mite blend to the ash mid lengths and ends ?? But roots too warm compared to rest of hair . Any advice on wot to use now . She doesn’t mind goin to warm blonde ... she’s naturally bout 7/8 .
