Over 6 inches dark brown hair with some grey. I wash 2-3 times per week with organic or Monat shampoo, conditioner. Our diet is high in vegetables, clean protein and no sugar.
I air dry my hair and wear in a braid. On special occations I curl with an ionic curling iron on the lowest setting, approximately four times a year.
The circumference is over 4 in. But less than 4.5.
