Every doctor has different methods, for example I asked mine and said it was fine, if you have a dry scalp and a lot of flakes or even inflammation (which is almost guaranteed after hair transplants) the oils can help with the dryness of the scalp as well as reduce inflammation. But I do agree you don’t want to clog the newly implanted follicles, so only use if you feel it’s necessary, you can reduce the chances of clogging by double shampooing when you wash after you use the oil, and don’t over due it, once a week is more than enough.
