Mine are coming in wirey and course, slightly silver. I've had a box of henna coloring in my closet for over a year and just haven't pulled the trigger yet for fear of really messing it all up. I did try just getting highlights to try to disguise/blend the gray that was coming in but I've been told never to use henna before or after salon coloring (ex-husband was a cosmotologist). It's been well over a year since the highlights so I think it'll be fine to use the henna.
I'm just wondering if it smooths long, poofy locks.
