When to start getting hair systems with grey?

[doubleindemnity]

I'm around 35 and I have been wearing a system for around 4 years. I have black hair and buy a natural black or jet black. Once I bought one with (supposedly) 10 percent grey but when it arrived it had a lot more than 10 percent. My stylist said that it looked stupid on me, like it had more than 30 percent grey and so I returned it. I haven't tried any grey since then. Do you think that now is the time to try ordering and wearing a 10 percent grey? Or, alternatively, would it be better to dye my bio hair fully black and stick with solid colour hair systems? I think that a bit of gray would look good and age appropriate, but I'm just worried that I'll order a 10 percent and I'll get something else again

Can you order black and have your hair person add some grey? 35 you can still stay all black if you want but if you do the grey it really has to match your natural hair or will look ridiculous.
