One of the younger women, in her 30's, just came out to tell me she is getting some grays in her brows. She will be visiting the hairdresser soon for hair color, and I told her to ask the hd to color her brows at the same time. Even if you want them a different color, in this case, not blonde, your hd should do this gratis. It's a simple procedure that makes a huge impact. Who wants gray brows?!
