When it comes to personal hygiene, most people have a habitual sequence they follow in the shower—perhaps starting with their face, hands, or hair. But what if we told you that focusing your cleansing efforts on one specific area first could revolutionize your skincare routine and even prevent irritation? According to dermatologists, the first place you should wash in the shower isn’t what you might expect—and changing this small habit can make a big difference in your skin health.
Many skin issues, from body acne to eczema flare-ups, are exacerbated not by dirty environments but by the order and manner in which you wash your body. Experts are now advocating for a strategic approach that prioritizes your body’s dirtiest and most sensitive regions first. This ensures that surface bacteria and excess oil are thoroughly removed without contaminating cleaner areas you may wash later. Let’s take a closer look at the area dermatologists recommend starting with in the shower and why it can play a key role in skin protection and overall hygiene.
Key information about optimal showering routines
| Recommended first area to wash | Underarms |
| Reason for focus | High bacteria concentration, reduces spread during shower |
| Common mistake | Starting with face or hair, transferring bacteria downward |
| Suggested body washing order | Underarms → Private areas → Feet → Arms/Legs → Face → Hair |
| Skin issue prevention | Acne, folliculitis, irritation, musty odor |
| Best type of soap | Gentle, antibacterial, fragrance-free |
Why your underarms deserve top priority
According to board-certified dermatologists, your **underarms** should be the first place you wash when stepping into the shower. This area often harbors the densest concentration of bacteria due to its warm, moist environment, and it’s also where sweat tends to accumulate quickly. By cleansing this region first, you’re not only reducing the chance of transferring bacteria to other, potentially more sensitive skin areas, but you’re also minimizing your risk for conditions like folliculitis and body odor.
“Starting your shower by cleaning your underarms helps remove bacteria and sweat build-up early. It prevents the transfer of odor-causing bacteria to other skin areas, making your overall hygiene more effective.”
— Dr. Maya Jensen, Dermatologist
The ideal shower order for healthy skin
Once your underarms are clean, the next areas to target are your **private parts**, followed by the **feet**, which are also prone to fungal infections and bacterial build-up. Washing these regions early reduces cross-contamination and ensures a more hygienic cleanse overall. After taking care of these high-risk zones, move on to the **arms and legs**, which comparatively carry less bacteria. Finally, wash your **face** and **hair**, especially if you’re using products that may contain harsh ingredients.
Why face and hands should not come first
Many people instinctively wash their face or hands first under the spray of warm water. Yet, dermatologists caution against this. First, your **hands** are constantly exposed to surfaces and bacteria; cleaning them may seem harmless, but it doesn’t help overall cleanliness if done before the germ-prone regions. Moreover, washing your **face** first risks having residue from hair products or body soap travel downwards, irritating facial skin. Starting with the underarms, instead, sets up a one-directional flow that keeps bacteria-fueled residue from lingering on sensitive areas.
The importance of water temperature and soap choice
Hot water may feel relaxing, but it strips away natural oils and disrupts the skin’s protective barrier. Lukewarm temperatures are best for preventing **dryness and sensitivity**. In addition, choosing the right **soap** matters. Fragrance-laden or alcohol-based products often aggravate the skin. Experts recommend **gentle, pH-balanced cleansers** that clean effectively without harsh side effects. This is particularly important for underarm and groin areas, where the skin is thinner and more prone to inflammation.
“Stick to lukewarm showers and sulfide-free cleaners. The combination of hot water and harsh soap can lead to microtears and irritation, particularly in moist body folds.”
— Dr. Elijah Pearl, Clinical Dermatology Specialist
What to avoid in your shower routine
There are several habits that, while common, can undermine your skin protection goals. These include:
- Washing your hair last, which leaves shampoo residue on your back
- Using abrasive loofahs that irritate the skin barrier
- Applying bar soap directly onto the skin instead of lathering with hands
- Neglecting your feet and the spaces between toes
- Using deodorants right after a hot shower, causing pore blockage
Post-shower care matters too
Your hygiene routine doesn’t end when you step out of the bathroom. Proper **post-shower care** includes gently patting the skin—never rubbing it—dry with a clean towel before applying a moisturizer within three minutes to lock in hydration. By consistently moisturizing after your shower, especially in winter months, you help maintain the skin barrier that shields you from infections, allergens, and environmental pollutants.
Real-world benefits of cleaning in the correct order
Changing up your shower sequence may sound trivial, but studies and anecdotal experiences show tangible results in as little as a week. Individuals who began washing their underarms first reported fewer instances of **body odor**, improved **skin smoothness**, and less **itchiness post-shower**. For those dealing with body acne, especially on the chest or back, dermatologists found up to a **40% reduction** in breakouts over time when the regimen included cleansing the most bacteria-prone zones early.
“Effective shower sequencing isn’t just about soap and water—it’s a scientifically backed approach to healthier skin. Starting at the right place sets the tone for the whole cleanse.”
