Mid-forties here and it happened to me this year. They look rather strange because now they're starting to come out, but if more came in, they would blend in. It's like when the gray starts coming in, the pattern is not flattering but as soon as there is plenty of it, as it whitens, it's not as noticeable.
I'm accepting this... I did not buy any products. I didn't really find what I was looking for and then gave up.
Am just trying to keep them up by having a decent shape.
Also, am too lazy to put on makeup. But I do wear sunscreen, put on some vitamin c in the mornings, and retinol at night. Moisturizers are vaseline, nivea, and Trader Joe's balm.
