Many sunscreens contain ingredients harmful to coral reefs. Hawaii announced a ban on sunscreens containing oxybenzone or octinoxate, which goes into effect in 2021. Our family switched to zinc oxide sunscreen, which doesn’t hurt coral reefs. We like Thinksport SPF 50+ ($10.25 per tube). — MF

I’m always amazed and slightly annoyed when the hotel hair dryer works better than my more expensive one back home. This hair dryer is inexpensive, portable and works just as good as any $50+ dryer. — CD

Because of the Tangle Teezer, I actually like brushing my hair after I shower. Just a few, quick strokes and my hair is super smooth and detangled. I’ve used the Tangle Teezer on my 10-year-old niece, who has really long hair and hates getting it brushed, and there was not one complaint. A tip for brushing long hair painlessly: gather all hair in a fist and brush in sections from the bottom up. — CD

Over the years I’ve spent anywhere from $20 to $150 on heat styling tools, and this $25 Remington Curling Wand is the best hair curler I’ve ever owned. It heats up in 30 seconds and the curls keep all day, even through the next day. I owned the smaller ½-inch wand for 5 years before I bought the larger 1-inch wand and now I can curl all my hair in less than 5 minutes. — CD

I use my satin pillowcase ($10) on nights before “no-wash” hair days. The silky pillowcase prevents my hair from getting tangled up or matted so that I barely have to brush it or style it. Beauty blogs claim that these pillowcases also prevent face wrinkles while you’re sleeping, which would be an added bonus if true! I just like how it makes my hair look and how cool and soft it feels. — CD

My favorite quick-fix hair product is Bumble and Bumble Brilliantine. The product description says it’s unique and hard to define, and it’s true. I use it when I don’t have enough time to heat style my hair. I rub a dime-size amount between my palms and pat it through out my hair to smooth it out, create shine and get rid of flyaways. — CD

If I don’t spike my hair, I look like Captain Kangaroo or Moe Howard. Bangs may have worked for those two august gents, but it doesn’t for me. The best styling gel I’ve come across is Got2b Ultra Glued Invincible Styling Gel ($8 for a 2-pack as an Amazon Prime Add-on Item). A little dab does the trick, and it lasts all day. — MF

These spin pins are essential for holding your hair in place in a perfect little bun. They never loosen or fall out, even while working out. My only problem is that I’m always losing them and rebuying them. — CD

I bought an Aquis Microfiber hair towel and I use it every day. It’s probably shaved off a minute or two of blowdrying, but what I really appreciate is that my hair is breaking less, and visibly smoother and less frizzy. Also, it’s much more comfortable to wear a lighter, less heavy towel on my head. — CD

Some days I skip out on washing my hair. After my reserve of complimentary hotel shower caps ran out, I needed to buy my own. These are cheap and long-lasting, but the prints are what sold me — nostalgic and fun. Reminds me of my grandmother in Mexico. — CD

Dry shampoo works great at absorbing oil and making my hair look clean when I skip out on washing it. All brands pretty much work the same, and you could even use talcum powder. I prefer Batiste Dry Shampoo because it comes in “brunette”, which spares me having to aggressively comb out the white powder from other shampoos. — CD

I often get sinus headaches and sometimes when I fall asleep with a headache, I will wake up with deep wrinkles from brow furrowing throughout the night. Frownies helps to prevent these from forming. I’ve already gone through a box and will continue reordering. — CD

I’ve been using the Clarisonic Mia2 for a couple of months now and I’ve seen a definite improvement in the appearance of my pores and brightness of my skin. It does a really great job at removing my makeup and exfoliating. I can’t imagine living without it now. — CD

Last year I started using a Salux Japanese Nylon washcloth, and I won’t ever go back. No other product has made me feel this clean before. It exfoliates, but it’s not as rough as some gloves or loofahs I have tried, and I use the one labeled “super hard.” — CDfor

Blotting sheets are a savior when my face gets oily and I don’t want to ruin my makeup. Clean & Clear Oil-Absorbing Sheets are cheap and portable. But if you find yourself in need and without, just use a sanitary toilet seat cover — they work just as good. — CD

I’ve installed inexpensive bidets in the toilets at my house, and I’m sorry I can’t bring them with me when I travel. But I have recently started carrying a DUDE Wipe packet in my pocket. The packet resembles a condom packet, but it contains a flushable single wipe. It’s unscented and is treated with vitamin E and aloe. — MF

The civilized way to floss is to use a long-handled floss bow so you don’t keep putting your fingers deep into your mouth. I’ve been using a Reach Access Flosser for many years, now rebranded as Listerine Ultraclean Reach. Rinse after use, and replace the cheap tiny bow as needed. — KK

GUM Soft-Picks do a better job than toothpicks or floss for cleaning food and plaque from between my teeth. The soft green brush pushes out all the gunk without hurting. I buy the version that comes with the travel cases. — MF

For a variety of reasons, most hotels don’t supply toothpaste in rooms. (Here’s an article from Slate that explains why.) And you can’t take a standard-sized tube in carry-on luggage because the toothpaste police at the airport will confiscate it. I stock up on 12 packs of 0.85-ounce tubes of Crest. — MF

This small $15 electric razor from Philips Norelco uses 2 AA batteries. I bring it with me when I travel and have started using it at home too, because it works so well. — MF
