20 inches of virgin red hair with natural blonde highlights and streaks of auburn throughout. Never dyed or blow-dried. Straightened/curled only 3 times. For most of the time i was growing my hair out, i was also supplementing biotin. Hair is mostly straight, but does have some natural waves. Typically washed every 3-4 days, as i find this strikes a good balance for my hair's natural oils. Non-smoker.
