People might tell you that trimming your eyebrows isn't cool but neither is being in your late forties and looking like a yeti.
After 45, when I cut my hair, I get less debris than when I trim my eyebrows. And .. the whole lot looks like someone simultaneously spilled salt and pepper.
Salt and pepper is exactly what it's like!!
Coincidentally, it seems that as I reduce the salt in my diet, there is more in my hair.
He,y, I have found the same thing!
