Good hygiene comes down to a handful of daily habits that keep your skin, hair, and body healthy and comfortable. Most of it is simpler than social media makes it look. Here’s a practical, head-to-toe guide covering what actually matters and why.
Showering and Body Washing
A daily shower or bath is enough for most girls, though you can adjust based on activity level. Focus soap or body wash on the areas that actually produce odor: armpits, feet, groin, and under the breasts if applicable. The rest of your body does fine with just water most days. Harsh scrubbing or using very hot water strips your skin’s natural moisture barrier, so warm water and a gentle cleanser work best.
Taking Care of Your Face
Wash your face twice a day, morning and night, with a gentle cleanser. That’s the baseline recommended by dermatologists, and it’s enough for most skin types. If you have oily skin or mild acne, look for a cleanser containing benzoyl peroxide or salicylic acid. Salicylic acid tends to be gentler and works well for sensitive skin, while benzoyl peroxide is better at cutting through excess oil.
Beyond cleansing, keep your routine simple: a moisturizer after washing (yes, even if your skin is oily) and sunscreen during the day. Pediatric dermatologists specifically caution against the elaborate multi-step routines popular on social media. Most of those products are unnecessary for teen skin and can actually cause irritation.
One easy upgrade: swap your pillowcase every few days. Oil, dead skin, and bacteria build up on the fabric overnight, and sleeping on a dirty pillowcase can trigger breakouts, especially if your skin is already acne-prone.
Understanding Body Odor
Body odor during puberty isn’t caused by sweat itself. Your body has two types of sweat glands. The ones spread across most of your body produce sweat that’s mostly water and salt, which is virtually odorless. The glands concentrated in your armpits and groin, however, produce sweat containing fats and proteins. Bacteria on your skin break those compounds down, and that’s what creates the smell.
This is why daily washing of your armpits with soap matters. It reduces the bacteria responsible for odor. After that, deodorant and antiperspirant serve different purposes. Deodorant masks or neutralizes the smell. Antiperspirant temporarily blocks sweat glands to reduce moisture. You can use one or both depending on what works for you. If you sweat a lot, an antiperspirant applied to clean, dry skin (even at night) tends to work best.
Vulvar Hygiene
The vagina is self-cleaning. It maintains its own balance of bacteria and a slightly acidic pH that protects against infections. You never need to clean inside it, and doing so with douches, sprays, or soap actively disrupts that balance. Douching is linked to a sixfold increase in bacterial vaginosis and raises the risk of pelvic inflammatory disease and other infections.
The vulva (the outer area) does need gentle cleaning. Avoid regular soap, scented body wash, bubble bath, and wipes in this area. Instead, use plain water or a mild, fragrance-free wash with a pH between 4.2 and 5.6, which matches the natural acidity of the skin there. Wash gently with your hand, always wiping or rinsing front to back to keep bacteria away from the urethra. Pat dry rather than rubbing.
Choosing the Right Underwear
Cotton underwear isn’t just an old-fashioned suggestion. Synthetic fabrics like nylon and polyester trap heat and moisture against the skin, creating conditions where yeast and harmful bacteria thrive. Cotton absorbs more sweat and allows air to circulate, which helps maintain a healthier balance of bacteria. If you prefer synthetic underwear for comfort or style, look for pairs with a cotton-lined crotch panel. Change your underwear daily, and switch to a fresh pair after exercise or heavy sweating.
Periods and Menstrual Products
Change tampons every 4 to 8 hours, and never leave one in longer than 8 hours. This guideline from the FDA exists primarily to reduce the risk of toxic shock syndrome, a rare but serious condition. Symptoms include a sudden high fever (102°F or higher), vomiting, diarrhea, dizziness, and a rash that looks like a sunburn. If you experience these while wearing a tampon, remove it and seek medical attention immediately.
Pads should be changed every few hours as well, depending on your flow. Menstrual cups and discs can typically stay in longer (up to 12 hours), but always follow the instructions for your specific product. During your period, a quick rinse of the vulvar area with water when you use the bathroom can help you feel fresher, but scented menstrual wipes are unnecessary and can cause irritation.
Hair Washing Frequency
How often you need to wash your hair depends entirely on your hair type. Fine, straight hair produces and shows oil faster and generally needs washing every one to two days. Curly or wavy hair can go longer, often two to three days. Coarse, tightly coiled, or very curly hair is naturally much drier and typically only needs washing every one to two weeks. Washing it more frequently can strip the natural oils that keep it moisturized and healthy.
Regardless of hair type, focus shampoo on the scalp where oil accumulates, not the ends of your hair. Conditioner goes on the mid-lengths and ends, not the scalp. If your hair gets sweaty between wash days, rinsing with water alone or using a dry shampoo at the roots can help without over-stripping.
Oral Hygiene Beyond Brushing
Brushing twice a day for two minutes covers the basics, but your tongue deserves attention too. It carries the highest bacterial load of any surface in your mouth, with over 100 bacteria attached to each cell on its surface compared to around 25 on other oral tissues. In studies on children, adding tongue scraping or tongue brushing to a daily routine produced significant reductions in plaque within 10 days. Brushing teeth alone, without cleaning the tongue, showed no meaningful plaque reduction over the same period.
You can use a dedicated tongue scraper or simply brush your tongue gently with your toothbrush from back to front. Floss once a day to remove the buildup between teeth that brushing can’t reach.
Hand and Nail Care
Wash your hands with soap and water for at least 20 seconds, focusing on the areas most people skip: between the fingers, under the nails, and the backs of the hands. Keep nails trimmed and clean. Dirt and bacteria collect under longer nails and transfer to your face, food, and everything else you touch throughout the day. If you wear nail polish, watch for lifting or chipping where moisture can get trapped against the nail.
Foot Care
Athlete’s foot is caused by fungi that thrive in warm, damp environments, and the spaces between your toes are the most common site of infection. Wash your feet daily and, just as importantly, dry them completely afterward, especially between each toe. Change your socks daily, and if your feet tend to sweat, switch to moisture-wicking socks. Rotate your shoes so each pair has time to dry out between wears, and wear sandals or flip-flops in shared showers, locker rooms, and pool areas.
