Shaving isn’t one-size-fits-all. There’s no universal formula or single ‘correct’ way to get smooth, but if your current routine involves guesswork and a little irritation, your skin is asking for better. Lucky for you, we’re smooth skin experts—and ready to let you in on all the best secrets for achieving dolphin-smooth, fuzz-free legs, underarms, and even sensitive areas like the bikini line.

This guide has everything you need to know about how to shave properly—from choosing the right razor and prepping skin, to the best shaving technique and post-shave care. Apply these tips to your next shave to help minimize irritation, prevent ingrown hairs, and keep skin smooth. Whether it’s your first shave ever or you’ve been getting smooth for years, there’s a good chance you’ll learn something new. Happy shaving!

Before You Even Pick Up a Razor

Most shaving problems start before the blade ever touches your skin. Start with the right tools and products, and everything else gets easier.

Choose the right razor.

Blade sharpness is essential when it comes to a good shave. A fresh, sharp blade helps you get a close, smooth result, while a dull one is more likely to tug at hair, nick skin, and even damage your skin barrier. And while blade count can be important, it matters less than you think—a well-designed five-blade razor past its prime will always lose to a fresh three-blade razor.

Here’s what’s actually worth paying attention to when choosing a razor: a flexible, pivoting head that follows the natural curves of your body, a lubrication strip to help reduce friction, and a grippy handle that won’t slip out of your hand mid-shower. Plus, don’t ignore blade replacement. Swap your blades more often than feels necessary—most people push them two or three shaves past their prime. If it starts to feel dull or drag on the skin, it’s time for a fresh blade.

Prep your skin.

Warm water is non-negotiable in your shave routine. When hair absorbs water, it swells and softens, so the blade can cut more cleanly—with less force, less drag, and less risk of irritation. Aim for two to three minutes of warm water exposure before you start shaving. This is also why shaving in the shower beats shaving in the sink. Running water keeps skin hydrated throughout the process, instead of cooling off halfway through. But don’t go in right at the start—give the water a minute to soften the hair and skin, and then reach for your razor. Note that super hot water can sensitize skin so make sure it’s warm, not scalding.

Exfoliate, but not today.

One of the most effective ways to prevent ingrown hairs is regular exfoliation. It helps remove dead skin cells, excess oil, and product buildup, keeping follicle openings clear and reducing post-shave irritation. Depending on your skin type, a physical buffing bar or chemical exfoliator may be the right product for prepping (or resetting!) your skin. Always start with a patch test and find what works for you.

But remember that timing matters. Always exfoliate the day before you shave, not the same day. Shaving is somewhat of an exfoliating act, naturally removing dead skin and buildup and hair, so exfoliating at the same time can make irritation more likely. Between shaves, aim to exfoliate every two to three days to keep buildup in check.

The Universal Technique Principles

Here are the five golden shaving rules, no matter where you shave. If you struggle with issues like razor bumps, irritation, or ingrown hairs, find out why—and how to fix it.

1. Lubrication is non-negotiable.

Dry shaving isn’t the shortcut to smooth skin—it’s the fast track to irritation. Even if you’re running late and only have a few minutes to shave, good lubrication reduces friction and damage to the skin barrier, which often leads to razor burn and bumps. That’s why it’s so important to prioritize a good shave prep or shave aid. Water alone isn’t enough to shave, and bar soap rinses off too quickly to provide consistent slip.

Use shave cream, gel, foam, or oil to help create a protective barrier between the blade and your skin so your razor can glide without dragging. Apply a generous layer (not just a thin film!), and reapply before any second pass. You want to create that seamless swipe. Remember to never drag a dry blade over already-shaved skin.

2. Light pressure.

Remember that you’re guiding the razor, not forcing it. The blade should do most of the work. Pressing down pushes the blade below the skin’s surface, increasing the risk of irritation, ingrown hairs, and barrier damage. Try the two-finger test: if you can’t hold the razor comfortably with just two fingers, you’re probably using too much pressure. And if you feel like you need to press for a close shave, your blade is likely dull.

3. Direction matters.

Shaving with the grain (in the direction your hair grows) means less irritation, even if it’s not quite as close. Shaving against the grain can get you a closer result, but it comes with a much higher risk of razor bumps and ingrown hairs. Start with the grain on your first pass, always. Only go against it if needed, and stick to lower-risk areas.

4. Fewer passes beats more passes.

Every stroke adds friction and stress to the skin. One clean, well-lubricated pass is better than multiple quick ones over the same spot. Remember the goal isn’t always the closest possible shave—it’s smooth skin with minimal irritation.

5. Rinse the blade constantly.

Every two to three strokes, rinse the buildup between the blades. It may seem like an annoying extra step but hair, dead skin, and product can clog the razor. This can increase drag, reduce performance, and spread bacteria which is a no-no. So remember to always swipe-rinse-swipe.

How to Shave Your Legs

Legs cover the most surface area, which means prep matters more here than almost anywhere else. Let’s dive in.

Setup:

Sit on the edge of the tub or prop your leg on a shower shelf—both are safer (and easier) than balancing on one foot. Start at the ankle and work upward in sections.

Step by step:

1. Start with a warm shower, giving your legs at least two to three minutes under the water before you begin.
2. Apply shave cream, shave gel or shave oil from ankle to knee, then reach for your razor.
3. Use light pressure and shave in long, smooth upward strokes, letting the blade glide across your leg. Note that on most legs, hair grows downward, so shaving up is technically against the grain. However, shaving toward the knee typically gives a closer shave without the same risk of irritation you’d see in more sensitive areas.
4. Rinse your razor blades every two to three strokes, making sure hair and product wash away before you turn back to your leg.
5. Reapply shave cream as needed.
6. When shaving the knee, bend slightly and use short, careful strokes around the curve. This is the most common spot for nicks, so slow down and take your time around this uneven surface. The hair above the knee is usually finer and grows in multiple directions. Switch to shorter strokes and stay mindful of how much pressure you’re using.
7. Once you’re done shaving, rinse the skin with cool water, pat dry, and apply a moisturizer or post-shave lotion while skin is still slightly damp.

Common mistakes to avoid:

• Skipping moisturizer. Legs are where people most often skip post-shave hydration, but that tight, dry feeling after shaving is a sign your skin barrier needs support. Moisturize, always.
• Using too much pressure on bony areas: Ease up on the pressure around the ankles and shins to avoid irritation.
• Rushing the knee: It’s not a race. Most shaving nicks happen around the knee so remember to slow down around the trickier curves and contours.
• Ignoring seasonal changes: In wintertime, cold, dry air can weaken or compromise the skin barrier before you even start. Using a body oil or a richer shaving cream can make a noticeable difference in your shave routine.

How to Shave Your Underarms

Underarms are one of the trickiest areas to shave—and most guides don’t explain why. Hair here doesn’t grow in one cohesive direction. Pit hair grows in multiple directions, often in a radial pattern from the center, so a single pass won’t catch everything. The skin is also thinner, folds easily, and is in constant contact with deodorant and clothing—all of which can increase irritation.

Step by step:

1. Raise your arm fully and stretch the skin flat. Shaving over folds increases your risk of nicks and missed spots.
2. Wet the skin thoroughly with warm water, then apply a generous layer of shaving cream.
3. For your first pass, shave in a slow, downward stroke. Most underarm hair grows this way, but check your growth pattern to be sure.
4. On the second pass, shave horizontally, across the grain. Rinse your razor every two to three strokes.
5. If you need a third pass, shave upward using very light pressure.
6. Remember to stick to short strokes. Long passes over multi-directional hair can mean missed patches or increased irritation.
7. Finish with a cool water rinse, pat dry, and wait at least 10–15 minutes before applying deodorant to help minimize any stinging or irritation.

When to apply deodorant after shaving:

Applying deodorant right after shaving is one of the most common causes of underarm irritation. Why? Because shaving temporarily compromises the skin barrier, and ingredients like aluminum and fragrance can sting or cause redness when applied immediately after. The best thing you can do for your skin is wait at least 10–15 minutes for your skin barrier to recover. If you’ve been dealing with post-shave irritation, this one change can make a noticeable difference. Even better: shave at night and apply deodorant in the morning.

Common mistakes to avoid:

• Using one long, single-direction pass: Underarm hair grows in multiple directions—your technique should too.
• Not fully raising your arm: Skin folds make it harder to shave cleanly and safely.
• Applying deodorant immediately after shaving: Give your skin time to recover.
• Using a dull blade: Underarm skin is more sensitive than legs, so a blade that still “works” elsewhere may already be too dull here. When in doubt, swap your blade.

How to Shave Your Bikini Line

The most tricky and sensitive area of them all: the bikini line. It requires a very delicate shave, so we jotted down all the specifics for shaving ‘down there’.

Bikini line vs. bikini area.

The bikini line is the strip along your underwear or swimsuit edge—generally, it’s lower risk and definitely more forgiving. The bikini area includes the pubic mound and surrounding skin, which is way more sensitive, higher stakes, and requires a more careful approach. Let’s talk about shaving both.

Why this area is the hardest zone to shave.

The hair that grows around your bikini area, also known as pubic hair, is much coarser than in other places. Unlike leg hair, hair down there often grows thicker but the skin is thinner and more sensitive. Add constant friction from underwear, heat and moisture, and you’ve got the perfect setup for irritation and ingrown hairs. Translation: this area needs the most prep, the sharpest blade, and the most thoughtful post-shave care. If something’s going wrong, it’s usually one of those three issues.

Step by step:

1. Start with a fresh, sharp blade. Don't use one that's already been through a full leg shave.
2. Prep with warm water for at least two to three minutes, then apply shaving cream generously.
3. Apply a generous layer of shave cream. If you want to be even more careful, use a shave aid specifically formulated for pubic hair.
4. On the first pass, shave with the grain. Hair in this area typically grows downward and slightly outward, but check your growth pattern to be sure. Use short, light strokes with minimal pressure. Aim for one clean pass.
5. If you need a second pass, reapply shaving cream and go across the grain only. Avoid shaving against the grain here—it significantly increases the risk of razor bumps and irritation.
6. Rinse with cool water. Pat dry. Apply a soothing, non-comedogenic post-shave product.
7. Wear loose cotton underwear for the rest of the day. Natural fibers allow the area to breathe and help to avoid unnecessary bacteria growth.

First time shaving the bikini area.

Go slowly and keep it simple—stick to shaving with the grain only. Some redness the first few times is normal. A mirror can help with visibility and angles. If hair is longer, we recommend trimming first with scissors or a hair trimmer. Trying to shave longer hair can clog the razor and reduce cutting efficiency.

Common mistakes to avoid:

• Using a dull blade: Always shave with a fresh, sharp blade to avoid causing irritation in this area.
• Shaving against the grain: Especially on the first pass, going against the grain is a high risk for razor bumps and ingrown hairs.
• Shaving right before tight clothing: Swimsuits and workout gear increase friction when skin is most sensitive. Shave at night or on a day you know you can wear loose, flowy clothing.
• Skipping post-shave care: Skin might look fine immediately, but irritation and bumps often show up 24–48 hours later.

Your Razor: When to Replace It

We recommend switching out your razor blade every five to seven shaves. Replace it even sooner for the bikini line and underarms, which generally are harder on blades than legs. You’ll know it’s time when the blade starts to drag instead of glide, when you find yourself unconsciously adding pressure, or when you suddenly get irritation you don’t normally see. A worn lubrication strip is another clear sign it’s time for a new cartridge.

Don’t store your razor face-down on any surface. Hang it on the shower wall or somewhere away from the shower puddle. Standing water speeds up rust and blade degradation. After each use, rinse your razor thoroughly under warm water and avoid tapping it against the sink—that can misalign the blades.

Shaving for Sensitive Skin

Sensitive skin isn’t a reason to avoid shaving, it’s a reason to adjust your shave routine. Here are some quick tips for shaving sensitive skin.

• Swap physical scrubs for chemical exfoliants. Ingredients like lactic acid and glycolic acid help clear follicle openings without mechanical abrasion, which can cause more irritation.
• Go fragrance-free wherever possible—fragrance is one of the most common topical irritants, and freshly shaved skin is more reactive than usual.
• Stick to one clean, well-lubricated pass. Especially for sensitive skin, one pass is almost always better than two.
• Post-shave care matters just as much: ceramides, niacinamide, and colloidal oatmeal support barrier repair and help the skin recover more efficiently.

How Often Should You Shave?

Whatever works for you. There’s no “correct” frequency.

What does matter is recovery time. Skin needs time between shaves to restore its barrier function, and shaving the same area daily—without proper technique or post-care—can lead to cumulative irritation over time. Your skin is the best signal. If it’s still red, bumpy, or tight from your last shave, it’s not ready yet. Shaving again won’t fix it. If you’re stuck in a cycle of persistent razor burn or ingrown hairs, shaving less often is often the solution. Take a break, let skin reset, then rebuild the routine.

Quick Reference

Does shaving make hair grow back thicker? No! That’s just a myth. Shaving only cuts hair at the surface—it doesn’t affect the follicle, growth rate, or texture. Stubble just feels coarser because the tip is blunt, not tapered.

Shower or bath? Shower. Continuous warm water keeps skin hydrated throughout the shave.

Moisturize before or after? Moisturize after, always. Pre-shave, use a dedicated shave lubricant. Post-shave moisturizer supports barrier repair and helps maintain hydration.

Up or down on legs? Most leg hair grows downward, so shaving upward is technically against the grain—closer shave, slightly higher irritation risk. For sensitive skin, start with the grain first.
