A tan is built-in sunscreen. If you are capable of getting a good tan, maybe you should do it. The best approach, imho, would be to find a salon that has UVB lamps. Some salons have UVA lamps that they tout as 'non-burning'. They don't tell you that UVA is the band that causes most of the aging damage. If you go this route, you probably ought to check out the lamps yourself and do a little research on them. I wouldn't trust anything told to me by anyone who works at a tanning salon. Use low intensity and/or short exposures over a long time period. Don't try to get a dark tan in a week. In fact, don't try to get a dark tan period. Spray tans, as far as I know do not offer any UV protection.
The advantage of a shaved head is that you can put sunscreen on it. Even with a tan, you should use a good UVA sunscreen on your head and arms. I do that every day, though I might be a little more casual about it if I had a good tan. A tan will allow you to be exposed to more UVB without burning, but I don't know how much if any it helps against UVA. The wrinkliest human I ever saw had a dark tan. This guy lived at high altitude (Lake Tahoe), and I doubt he was over 60.
