My stylist and I have discussed the going gray for awhile.
When I saw her recently, she suggested doing my highlights lighter for summer and get things moving toward the gray rather than do the transition quickly.
I had a number of life changes in the last few months that have been difficult so she thought it might be better to wait.
She is a friend and knows me well. I am happy we are going slowly.
Thank you all for your replies and thoughts.
