Hi, Helaine: I felt very edgy in the first weeks of the Trump administration. I thought about altering my investments and even considered stocking up on gold coins. But my financial adviser talked me out of it and told me to stay the course. It worked for a time.

Trump's now threatening increasing tariffs on Twitter, the stock market is down and it feels as bumpy as I feared. Should I cut back on spending and save as much as possible? Or should I stock up on cheap stuff and anything else I think I will need before the prices go up, thanks to trade wars?

Should my wife and I invest our budget reserves in paying down our home loan to get out of debt, invest abroad, or keep more money in cash to keep our reserves as liquid as possible? What do you think? -- On the Financial Edge

Dear On the Financial Edge: I agree having a president who appears to use Twitter as a governing tool can be somewhat disconcerting. But don't let it scare you into upsetting what sound like well-laid-out financial plans. The stock market goes up, and it goes down. Trying to guess at this stuff is a fool's errand. I'd stick with your current investment plan and savings and spending strategies.

As I am forever pointing out to people, the stock market can go down 20 percent, but that doesn't mean your chosen alternative won't go down even more. Similarly, I wouldn't suggest stocking up on stuff you think you might use one day because you think tariffs will make the things more expensive, unless it's something you are sure you will need to purchase within the next few months in any case. Also, it's worth noting that tariffs hardly only impact unnecessary "cheap stuff." They can also impact everything from food to cars.

As for liquid savings, three to six months emergency savings is recommended -- no matter who the president happens to be. If you don't have that, I would suggest cutting back for a time to build up an easy-to-access nest egg.

But most important: Stay calm! It's when we panic that we make the biggest financial mistakes.

Dear Helaine: Help me out with this one. My salon, like most where I live, charges for a blowout after you get highlights. I do it once every few months as a treat -- it's $40. Or, I should say, I did it occasionally.

I had a big meeting with my boss scheduled the day after my last appointment, so I said yes, I'd love the help, when my colorist asked if I would like to schedule a blowout. When I paid the bill, I discovered I was charged $80. I asked the receptionist to look over the bill and said I thought there was a mistake.

She told me my blowout was done by a master stylist. When I responded that in the past the salon always used assistants for the task, she told me the salon recently changed that policy, and I should have realized I was in the hands of a senior stylist. I told her it was wrong to spring a doubling in price on me or any customer. After another minute of back and forth, she refunded the $40 as a courtesy "just this one time."

I'm now feeling guilty and wondering if it was all my fault for not asking the price in advance. What do you think? -- A Hairy Problem

Dear Hairy Problem: It is customary to send out an email notification of a change in salon prices, as well as to post a notification at the front desk. It doesn't sound like the salon did that in this case. I doubt you are the first person to experience this sticker shock, though you might well have been the first to speak up -- and good for you that you did!

If an establishment suddenly doubles the charge for a service, it needs to tell customers about it before they sign up for it. Springing a 100% price increase on a customer after the fact is not acceptable. Moreover, I know very few people who know all the stylists in their salon, so the idea that it's your responsibility for not recognizing the person is simple excuse-making. You did nothing wrong here. The salon did.

One other suggestion: Get your colorist's contact information. This is such an unusual situation, I wonder if the salon is experiencing financial woes. It's rare to see a price go up by that much, with or without notice. You don't want to be out a prized beautician if the establishment suddenly shuts its doors.

Dear Helaine: I’m self-employed and decided to take out some life insurance for my wife that doubled as an investment vehicle. It was explained to me that one advantage of it is that it’s permanent, rather than term, and as someone who is self-employed and in my late 30s, it’s helpful to have this locked in early.

My concern is that this appears to be a pretty inefficient investment vehicle. At the beginning of the year -- my third -- I had an accumulated balance of $566. This year I had a premium of $225 a month, and only wound up with an accumulating value of about $1,500. Is this a foolish product, or should I stick with it while investing in other retirement vehicles, like a Roth IRA? -- What to Do?

Dear What to Do: When my dad goes to a movie and he doesn’t like it, he’s not very patient. He gets up and leaves almost immediately. His reasoning? The money is already gone. He can either waste another hour of his life miserable, or he can get up and leave and get on with his day. I’m afraid you are at the same juncture here.

This is not a good investment, and it’s almost certainly not a particularly good life insurance policy either. If you need life insurance, you should have term life insurance. It’s significantly less expensive than whole life, which is what you are currently paying for.

You can get a term policy for 30 years, which is likely all you will need. Life insurance is meant to replace your work income, and when you retire, that will presumably no longer be necessary. Then take the cost difference on the two offerings and invest that for retirement via a Roth IRA.

As for whole life, it’s pitched as a way of protecting your loved ones while still setting money aside for retirement. In fact, you’ll pay multitudes more money for the protection, the investment options are limited, and it's often loaded with fees designed to make money for the seller and insurance company.
