How long should I wait after hair transplant before applying Dermmatch?

Good afternoon. I had a small filling session of 550 grafts two weeks ago. Today I had crusts removal and my doctor said that everything was fine, it's just a bit sore at the moment since the procedure of crusts removal at the clinic is a bit tough. My doctor said that, except sport for other two weeks, I am free to do everything, even apply the concealer. I wear short hair, so I mostly have to rub it on the scalp (very gently of course). Is it ok according to your opinion to pat Dermmatch on the scalp?
