My hair doesn't look that dense compared with others at 6 months post-op (Photos)

Heading into month 7 in december 10th. I want a second opinion of how my hair is looking, I worry about the density right now. I know patience is the key here and from month 4 to 6, there is a huge difference that make me happy. But now i am scared again when I compare to others at the same 6 month mark. My hair doesnt look that dense . Should I worry ?
