I bought a sauna. Second hand from a guy who had it in his third floor attic 50 miles away. Had to dismantle it get it in the van than rebuild it on my lean to.
I then got myself a big old whiskey barrel for a cold plunge pool.
No regrets, a sauna straight after coming off the hill in wet weather is the best.
I started balding in my late teens. Shaved my head for the first time at 20. Never looked back. Wished I'd done it sooner.
Still remember an offhand comment from a girl who said I have a nice shaped head.
A quick once over with the clippers once a week and you're good.
Whatever you decided to do don't stress about it! I'm sure that will only make it worse.
Bonus: the freshly shaved head acts as velcro to keep your hat on during windy days!
