Ah do not blame yourself you didn’t waste the grafts, the clinic that did this disgraceful job did. Hair restoration is a mine field, the best thing you can do is make the most positive steps from here out. Since you specifically asked for help - you are doing the right things now. See an expert dermatologist (sounds like you’ve got some good advice there) and wait until the skin has fully healed. Dr Bisanga actually did my ht (search for my thread if you’re interested) so I know he’s honest, ethical and will tell you the truth of what’s possible so I would say just try to be patient and see him again when he recommended. Oral minoxidil (2.5mg) had an amazing effect for me personally, so if you research that it could be worth a try. You’ve been through a lot - things can and will get better I’m sure just take your time and make the right calm decisions going forward - all the best!
