DH has short, mid brown hair which goes a bit reddish in the sun. He's got quite a few greys now on the sides and just found one on the top, the horror! I've tried to nudge him towards one of those root filler type brushes but he's not convinced and wants to dye it. I've been trying to find something semi permanent but with no luck so far. What would you use? I'm veering towards a warm dark blonde but they seem really quite dark from the photos and I think it might be too much? I'm terrified of doing a "Trump" with an unconvincing blondy-orangy shade. Thank you for your help.
