Natural virgin jet black, Asian straight hair

Jet black straight, shiny (according to many compliments) Asian hair. Remains naturally straight dry, humid, or wet. Occasionally twirled and clipped for natural wave. Healthy diet including collagen. No exposure to smoke, hair chemicals, no hot iron (prefer my hair straight) and combed thru and air dry. Washed every 3 days on “wash hair day” with cool water using moisturizing shampoo for scalp and Moroccan oil based leave on/ rinse off conditioner. Currently can cut upto 13 inches. Will have a professional cut my hair.
