13-14″ Brown male well kept

Hello there, I will be cutting my hair this week, Oct 9 2023, I have always used high quality shampoo and condition it every day. Biolage and Native are most recent. I brush it gently multiple times per day some days. I usually keep long hair and cut it every now and then, so I am familiar with how to care for it. I do not smoke or drink at all. I am 42 years old so a couple of grey hairs are coming through but I don’t think any of the long ones are grey just yet. If any questions let me know!
