DEAR HARRIETTE: My hair is turning gray, and it concerns me because I work in a young industry. Most of my colleagues are 20-somethings, while I am in my 40s. I am good at my job and seem to be appreciated. I make sure I look youthful enough and vital so I am not considered old.

Ironically, a couple of my office mates have dyed their hair gray. It seems to be a trend. Even so, I think I should dye mine brown. The trend works for young people. And, of course, it doesn’t seem to matter at all for men. For women, I think it’s a whole different ballgame. What do you think? -- To Dye or Not to Dye, Chicago

DEAR TO DYE OR NOT TO DYE: You are right on many fronts. Yes, it is a trend these days for women to dye their hair gray or white, different from the classic platinum blond that remains popular. I agree that it works best on people who seem to defy the age group for the color. Being young and hip with gray hair gives the color an edge.

That said, I will add that some women wear their natural gray hair beautifully and can maintain a semblance of youthful vitality at the same time. It depends on the style and cut that you wear and the rest of your overall appearance.

Given that you work in a youthful industry and ageism exists even if it is unconscious, you should figure out a look that makes you feel comfortable and competitive with your co-workers. Dyeing your hair is perfectly fine -- and commonplace. Consider dyeing your hair a fun color. Who said only the 20-somethings can have fun with hair color?

DEAR HARRIETTE: I have a great job, and I make good money. I’ve worked hard for it, and I feel good that my education and commitment are paying off, but I also feel uncomfortable because most of my friends are struggling. I help them out in different ways, like paying for dinner when we all go out and buying them great gifts for their birthdays, but I’m at a crossroads as to how to be comfortable with my good fortune.

I know my friends aren’t my responsibility in that way, but I don’t want to seem like I’m bragging when I make improvements in my life, like redoing my kitchen when one friend can hardly pay her rent. How do I reconcile my circumstances in comparison to theirs? -- Uneasy, Boston

DEAR UNEASY: Being generous with your friends is a kind and thoughtful action. Be careful not to overdo it, though. You run the risk of creating expectations that you will foot all of the bills when you are together. Balance that out.

In terms of how you live your life, do it without talking about it. Make your improvements, take your trips and do what you do without fanfare. When your friends visit, welcome them to your home and share your bounty without bragging about it or revealing costs. Your low-key manner will help to ease the economic divide.

DEAR HARRIETTE: I need to get a baby sitter for my son. I am going back to work, and he is too young for school.

The other moms I know have hired women who are good at child care but are paid off the books. All these women I’ve met are undocumented, which seems to be the trend here. From wealthy moms to those who are struggling, they all seem to hire in this way.

I’m afraid if I hire someone who is undocumented, I could get in trouble down the line. When I researched the on-the-books nannies, the prices were sky high. I’m not sure what to do. None of my friends have been caught. Do you think that is just the way it is now? -- Find a Nanny, Brooklyn, New York

DEAR FIND A NANNY: It is true that many mothers/families in New York City -- as well as other parts of the country -- employ undocumented workers to care for their children. This is not a new phenomenon; it is part of the ecosystem of the United States’ economy, believe it or not. But that doesn’t make it legal. There are many manual labor jobs, as well as home-care jobs, that are filled each year by people who are trying to get a leg up and pursue the American dream. And many of those people are living in the shadows.

In New York City some public officials have lost their jobs due to hiring undocumented nannies or hiring people for whom they did not pay taxes. It is illegal to hire someone and not contribute payroll taxes to the government.

You should hire a person who is filing with the IRS and paying taxes. There are undocumented workers who are on the road to legal status who do have legal identification and are law-abiding taxpayers. They would be the safest hires within that category, whereas documented immigrants (those with employment visas or green cards) or American citizens are best.

DEAR HARRIETTE: It’s not even Halloween yet, and my kids are already telling me what they want for Christmas. That’s because the kids’ channels they watch are cluttered with toy commercials. I hate it because I do not want them to think we are materialistic. I was taught to think of Christmas as a time to give to others and to spread joy, not to chalk up how much loot I collected. How can I teach this to my kids if they are inundated by commercial pleas to have their parents buy them things? -- In the Spirit, Cincinnati

DEAR IN THE SPIRIT: Your job is to teach your children your values. One way to do this is to limit their exposure to television. The fewer commercials they see, the less their longing will be for something they may not even want. Give them guidance on how you approach gifts during the holidays. Can they request one main gift? What are the boundaries of their wish lists? Tell them, and set their expectations for what they will receive and for what you expect them to give. By changing the conversation, you help to balance what they are seeing from outside sources and what you believe.

DEAR HARRIETTE: I need to provide a photo to an organization I’m joining, and I don’t know what to do. I am a woman of a certain age, and I much prefer my older pictures when I looked young and vibrant. I’m a professional woman, and I have worked very hard to achieve many goals, which didn’t leave too much time for glam or exercise. I’m about 40 pounds overweight. I look OK, but I don’t love the recent photos of me. The only professional photos I have are about 10 years old. I suppose I could wait for a few days and get another photo taken, but I fear I will hate capturing myself as I look today. Can I use an old photo of me for this organization? -- Reflection, Chicago

DEAR REFLECTION: I totally understand why you would be inclined to use an old photo, but I want to discourage you. This is because when people meet you, it is best for them to meet in person the same face they saw in a photo. If you look significantly different, that first interaction can be awkward. You should get a professional photo taken. You can ask the photographer to lightly retouch the photo to take away major blemishes while keeping your image consistent with who you are.

DEAR HARRIETTE: I just found an old journal and read a bit of it, and it disturbed me a lot. The journal was from about 15 years ago. What I was writing about then, my troubles, seemed like exactly what I’m going through today. Even though I have spent a big part of my life believing that I was working on improving myself and working on particular personality traits or behaviors in order to get better, when I read this journal I felt like such a loser. So much time has passed, and I still suffer from the same stuff. Is it even worth it to try to be a better person? It’s not that there’s anything horrible about me, but the little stuff adds up. What can I do? -- Stuck, Baltimore

DEAR STUCK: You are not alone. Most people live with their demons or flaws or personality quirks their whole lives. That doesn’t mean you should give up on aspects of your behavior you do not like, though. Consider finding that old journal as a wake-up call.

You have more work to do to improve on aspects of your personality, and you can get to work on these things right now. Write down the things you want to address, and then strategically figure out what to do. In some instances, you may want to seek professional help so experts can support your development. What you want to avoid is pretending you have no options. You do!
