If I look at an image of me in the army with a buzzcut and myself in the mirror now, the hair definitely looks thicker now. I don’t know how one’s hair “grows in texture” though, you’ll have to brief me on that.
Most of what I think you’re seeing is hairstyle and product, not transplants. But I wouldn’t put money on it.
I’ll have to trust your expertise, I guess. The hairline not being straight is suspect, but also, it might be perspective or something.
I does look kinda too straight in the second picture now that you mention it, though.
