The last time I went in for a haircut, my stylist asked me how it was possible that instead of my hair getting grayer, it was actually getting darker. I don't color my hair, and yes, at 62, I do have some gray hair, but it looks more like highlights than gray. I told her the only treatment that I use on my hair is Weleda's Rosemary Hair Oil. I've used it for years and love it. I'll apply it to my scalp in the evening, massage it in with my fingertips and leave it overnight til I wash my hair in the morning.
In doing a bit of research, Rosemary oil is known not only for helping grow and strengthen hair but also for reducing gray hair. Who knew?
Anyway, not a sponsor but here is the link if you want to check it out Weleda Rosemary Hair Oil. I buy mine at Sprouts.
