How am I doing so far - Hair Transplant - 45 days post op ? (Photo)

I was told by my Doctor that i will start having tiny hairs after the 3rd month and then it will start to grow and getting thicker , but after 45 days i have a lot of grown hairs as you can see in my photos and i see a lot of small tiny hairs too , Does that mean anything ? is it totally safe now to do whatever i want with my hair ? ( i had 1500 grafts to lower my hairline )
