How long can I use Dermmatch after transplant?

[BelfastBilly]

Hi all, I have a question about how long I need to wait after my transplant until I can use Dermmatch. I expect to have a red scalp for 4-8 weeks after the transplant, and also start to shed. I would like to cover the redness and later the shedding using Dermmatch so it is not so obvious to work colleagues that I have had a hair transplant, but the key question is how long is recommended before I can use concealers on or near transplanted hairs? (I have grey hair and have used Dermmatch for about 5 years).

Thanks, Billy
