My grey hairs are like ash blond colored high light now, and my hair is medium length ( 1-2" below collar bones) with fine layers and large curves(natural). The bottom was thinned so light that it flows in wind. I usually keep 4-5 different hair styles( including buns and braids) depends on my mood and occasions.
I only use very light, gentle, organic, nonpermanent hair coloring conditioners to blend the grey hairs.
