Mate i can relate to how you’re feelìng. It is a big step. I would say 2 things to you:
1. Speak to the pros. Get that consultation done as soon as possible and all your queries will be answered.
2. Shave your head and be honest with yourself. Are you happy to remain as you are? Chucking powder all over your head? If so, happy days… save a few bob. If not, this is a seriously good alternative and takes all the worries away.
