The way you take care of yourself can often send out signals to others that you may not realize. How you cut your hair, trim your nails, maintain your beard, and pluck your eyebrows can all contribute to your first impression. Psychology studies show that people form trust judgments in milliseconds, meaning they start to form an opinion about you before you even open your mouth. Unfortunately, not every grooming habit makes a good first impression. Some might actually make you look untrustworthy. Here are seven habits that could be damaging your credibility and make people second-guess you.
1. Overusing Cologne or Scented Products
There’s nothing worse than someone who overuses cologne or other scented products. While wearing a scent can be part of your personal brand, going overboard can send the wrong message. People might think you are attempting to mask poor hygiene or hiding something, in general. Additionally, research has shown that many people associate strong artificial scents with manipulation or overcompensation. It’s best to keep it light. One or two light sprays on pulse points should be good enough to stay memorable without being overwhelming.
2. Neglecting Nail Care
Dirty, jagged, or untrimmed nails don’t just look sloppy. They hint at a lack of attention to detail. In professional and romantic settings, hands are surprisingly noticeable because they’re involved in nearly every interaction. Neglected nails can make others assume you cut corners elsewhere, whether in work or honesty. Clean, trimmed nails, on the other hand, communicate discipline and self-respect. Even a quick weekly nail routine can dramatically improve how trustworthy you appear.
3. Poor Beard Maintenance
Facial hair can enhance masculinity and confidence, but a poorly kept beard can send the opposite signal. Uneven lines, stray neck hair, or food particles trapped in facial hair can look unhygienic or careless. Studies show people often associate scruffiness with unpredictability or dishonesty. Maintaining a clean neckline, symmetrical shape, and soft texture keeps your beard looking intentional, not neglected. Investing in a trimmer and regular conditioning routine can make all the difference in first impressions.
4. Greasy or Unkempt Hair
Your hair plays a huge role in how others perceive you. Greasy or unkempt hair will make you seem less reliable. If you’re rocking longer hair, make sure it’s washed and well-kept. In some cases, it might also be appropriate to braid it or pull it back. The same can be said for short hair. It doesn’t mean that you need salon-level maintenance every week, but you need to be consistent with your haircare. People typically associate good grooming habits with good character. So, don’t let your hair make people think poorly of you.
5. Overplucked or Neglected Eyebrows
Eyebrows frame the face and communicate emotion more than most men realize. Overplucked or overly shaped brows can make expressions look unnatural or insincere, while unkempt ones can seem wild or disheveled. Either extreme can trigger subtle discomfort in others, who rely on facial symmetry to read trust cues. The best approach is balance. Trim stray hairs, keep a natural shape, and avoid making brows too thin or too sharp. Your goal is to look approachable, not overly stylized.
6. Ignoring Oral Hygiene
Oral hygiene is a big deal, too. If you have bad breath, yellowed teeth, or buildup around the gums, people will question whether you are trustworthy. It doesn’t matter how charming or nice you are; your smell and appearance will lead people to judge you. When someone sees you don’t take care of your dental health, it can send a signal to others that you have no self-control or that you are careless. Not to mention, not taking care of your teeth can have an overall negative impact on your health. When you have a clean smile, it communicates honesty and confidence to others.
7. Wearing Dirty or Worn-Out Shoes
It might sound minor, but scuffed or dirty shoes are one of the first things people notice subconsciously. Shoes tell a story about how much effort you put into the details that matter. Someone who neglects their footwear often appears unreliable or inattentive to finishing touches. Polished shoes, on the other hand, show you’re organized and care about presentation. Clean them regularly, replace worn soles, and avoid pairing sneakers with formal wear if you want to project credibility.
Trust Starts With the Details
Trustworthiness isn’t just about character. It’s about how well your outer habits align with inner discipline. People draw fast conclusions based on small signals, and grooming is one of the easiest ways to control that narrative. By maintaining consistent hygiene and polish, you communicate that you respect yourself and others. The takeaway? When you look like someone who pays attention to the details, people naturally assume they can trust you.
