Hey buddy
I have to say I think Dr Pinto is correct about the hair length, your photos at 7.5 weeks they grey area is not as stark looking when compared to your earlier photos.
overall the healing is great, you didn’t need much work but there is not much redness. The work is clean and the donor is perfect.
you will be on for a great result. I know others have said to colour the hair if it remains grey, I don’t think you should, no reasonable reason but I feel putting chemicals on the hairs as harsh as colouring shouldn’t be done. I know women do it with no issues but it’s harsh on the hair and the scalp and you should keep it healthy
