Body Hair Grooming for Men UK: The Complete Guide to Shaving Below the Neck

Body hair grooming is now mainstream for UK men — but most do it with the wrong tools and technique. Here’s the complete, practical guide to shaving chest, stomach, back and more, without the irritation.

A decade ago, body grooming was considered the preserve of professional athletes and gym devotees. In 2026, it’s entirely mainstream. According to grooming market research, the majority of UK men under 45 now regularly manage body hair in some form — whether that’s trimming, shaving, or both. The challenge is that most men approach it with face-shaving tools and face-shaving technique, which produces mediocre results on the chest, stomach, and back.

This guide covers the specific considerations for each body area, the right tools for each job, and how to get a clean, irritation-free result every time.

The key difference between face and body shaving

The face and the body present very different shaving challenges. Facial skin is thinner and more sensitive but the surface area is small and mostly visible. Body skin is tougher but the surface area is larger, often contains more varied hair growth directions, and critically — large areas like the back are impossible to see directly while shaving.

Body hair is also often coarser than facial hair on many men, which means blades dull faster when used for body shaving. This is the main reason to use a separate razor for body and face — not only for hygiene, but to ensure each blade set stays sharp within its intended lifespan.

Chest and stomach

The chest and stomach are the most commonly shaved body areas for men. The skin here is relatively forgiving compared to the face — less prone to ingrown hairs and more resilient to blade contact. However, the nipple area requires particular care: short, careful strokes and no pressure around this sensitive skin.

For the chest and stomach, a SmartShave 3-blade or 5-blade cartridge razor works excellently. The pivoting head adapts to the contoured chest surface better than a fixed-head razor. Use short strokes, rinse the blade every few strokes (body hair clogs blades faster than facial hair), and apply a moisturiser afterwards — body skin dries out faster than facial skin post-shave.

Underarms

Underarms are a sensitive area with skin that folds and moves constantly. The hair grows in multiple directions simultaneously, which means a single directional pass will miss a significant portion. A multi-pass approach — with the grain first, then across — gives the best result.

The underarm skin is thin and prone to irritation. Always shave on warm, wet skin and apply a fragrance-free moisturiser or balm after shaving. Avoid deodorant immediately after shaving underarms — wait at least 10–15 minutes for the skin to settle before application.

Back and shoulders

Back shaving is genuinely challenging to do solo — it’s almost impossible to shave the centre of the back without a long-handled body shaver or assistance. Dedicated back-shaving tools with extended handles exist and are worth considering if back hair is a persistent concern. A regular cartridge razor can manage the sides and lower back, but the upper middle back typically requires a partner or a specialist tool.

The groin area

Shaving the groin area requires particular care. The skin here is thin, highly sensitive, and folds significantly with movement — conditions that create a high risk of nicks if technique is poor. The following rules apply specifically here:

• Use a completely fresh, sharp blade. Never use a blade that’s already been used for face or leg shaving. Fresh SmartShave blades with new aloe vera and vitamin E strips provide maximum lubrication on the most sensitive skin.
• Pull skin taut before each stroke. Loose, folded skin and a razor are a dangerous combination. Use your free hand to hold the skin firm and flat in the area you’re about to shave.
• Use very short strokes and minimal pressure. The same principle as face shaving — but even more critical here. Let the blade glide; never push it.
• Trim with clippers first if hair is long. A cartridge razor on long hair in this area will clog immediately. Trim to a few millimetres first, then shave.
• Rinse with cold water and apply an alcohol-free balm immediately. This area is highly prone to razor bumps. Cold water and soothing aftercare significantly reduce their frequency.

Body shaving and blade replacement

If you shave both your face and body, you’ll use blades faster than a face-only shaver. Consider either a dedicated second set of blades for body use, or factor the additional shaves into your replacement schedule. A blade used for chest and face shaving should be replaced every 4–5 shaves rather than 7. SmartShave’s monthly subscription at £14.99/month delivers four blades — if you’re dual shaving, consider starting with the £19.99 four-cartridge + handle option to build a small stock, then transitioning to monthly delivery.
