Oh I am so lucky to have received good "genes" from my grandmother's side. She never had grey hair. Just a few in front and on the sides. My mother on the other hand was in her twenties when she started going grey. My husband is losing his hair rapidly and he was also in his twenties when he started to turn grey. Luckily I love grey hair. Doesn't bother me at all, just NOT on myself. LOL!
