Thx Hersute for the fast answer, the color #4 for the stock unit was suggested my by John TL by looking my picture.
I will proceed to add some liquid sun cream to my conditioner, good hint ;-) You have any suggestion of a leave-in conditioner? By Sally's Hair & Beauty shop you can find so many different, that I have no idea which to buy…
About your last suggestion, my goal is for the future to order custom unit with the perfect color and density. But a question, the TL700 New Gen base is the same as the Thin Skin Stock unit base? Or is this an improvement of the thin skin stock unit base?
