I've raised £2000 to permanently remove my hair

I came home from football when a few days after my 11th birthday and collapsed in bed. Nothing new, I was always running around one minute asleep the next. What I woke up too was, However. Pain from head to toe, I couldn't see, I couldn't breathe... boom. Hospital.
Skip forward a few weeks, brain tumour. I was told I'm not going to live.
Skip forward to the operation, died twice on the table to wake up to the news it was unsuccessful and there was nothing to do.
Lots of my parents crying and arguing later the hospital begrudgingly agreed to give me an adults dose of radiotherapy.
Spoiler alert: I didn't die.
I was however left with a head of hair resembling a 55 year old man with 6 kids at the age of 21.
I just kind of get on with it but the truth is - it hurts. I had such awesome tight curls and now I'm left looking like a monk from Robin Hood.
My confidence suffers on a daily basis, especially when people comment that they think I'm much much older than I am purely because of my hair.
What I wish to do should I raise this money is go through a laser hair removal treatment to remove all hair from my head. As the gamma radiation destroyed the hair follicles, it also damaged the skin making hair transplant imppossible.
This would allow me to simply live a better life without constant maintenance of the graveyard that is my noggin that cancer left me with.
I wouldn't have to worry about spending an hour in the shower every 2 nights preparing for a client visit or even looking good enough to take my girlfriend to dinner, or avoiding awkward comments about how my hair is "receding" or be told I look nearly 40 years old.
I just want to look and feel my age without having to CONSTANTLY maintain it.
Really, I just want to move on.
I hope you can understand and if you can't contribute that you share this for somebody else to see.
Thanks for reading!
P.s. due to parts of my skull being removed to perform the operation and not healing flush, shaving is uncomfortable, time consuming and often messy.
