How to Prevent Ingrown Hairs When Shaving (Simple UK Guide)

by

Ingrown hairs happen when a shaved hair curls back into the skin instead of growing out. They’re painful, annoying, and completely preventable. This guide shows you how to stop ingrown hairs before they start — with simple steps that work for every skin type.

What Are Ingrown Hairs?

An ingrown hair occurs when a hair grows sideways or curls back into the skin. This causes:

  • Red bumps
  • Tenderness
  • Itching
  • Inflammation
  • Sometimes pus‑filled spots

They’re especially common on:

  • The neck
  • Jawline
  • Under the chin
  • Anywhere hair grows curly or coarse

1. Exfoliate Regularly

Exfoliation removes dead skin cells that trap hairs beneath the surface.

Use one of these:

  • A gentle face scrub (2–3 times per week)
  • A chemical exfoliant (salicylic acid or glycolic acid)
  • A soft exfoliating brush

Why it works: It clears the path for hairs to grow outward instead of curling inward.

2. Shave With the Grain (Not Against It)

Shaving against the grain cuts the hair too short and encourages it to curl back into the skin.

Correct shaving order:

  1. With the grain
  2. Across the grain
  3. Against the grain (optional — only if your skin tolerates it)

3. Use a Single‑Blade Razor

Multi‑blade cartridges lift and cut the hair below the skin surface — a major cause of ingrowns.

Better options:

  • A mild safety razor
  • A single‑blade cartridge
  • A foil electric shaver

4. Use a Sharp, Fresh Blade

Dull blades tug at the hair, causing it to snap below the skin.

Replacement schedule:

  • Cartridge razors: every 5–10 shaves
  • Safety razor blades: every 3–5 shaves

5. Prep Your Skin Properly

Soft hair cuts cleanly and reduces the risk of ingrowns.

Before shaving:

  • Wash with warm water
  • Apply a warm towel for 30 seconds
  • Use a slick shaving cream
  • Add pre‑shave oil if you have coarse or curly hair

6. Use Light Pressure

Pressing too hard bends the hair as it’s cut, increasing the chance it curls inward.

Tips:

  • Let the razor glide
  • Use short strokes
  • Keep the blade angle consistent

7. Rinse With Cold Water After Shaving

Cold water:

  • Reduces inflammation
  • Tightens the skin
  • Helps prevent irritation that leads to ingrowns

8. Apply a Soothing Aftershave Balm

Avoid alcohol‑based splashes — they dry the skin and make ingrowns worse.

Look for ingredients like:

  • Witch hazel
  • Aloe vera
  • Tea tree oil
  • Niacinamide
  • Salicylic acid (for prevention)

9. How to Treat Existing Ingrown Hairs

If you already have ingrowns:

  • Apply a warm compress
  • Use a salicylic acid or glycolic acid exfoliant
  • Apply witch hazel to reduce redness
  • Use aloe vera to soothe the skin
  • Avoid shaving the area for 24–48 hours

Do NOT:

  • Pick at the bump
  • Dig with tweezers
  • Squeeze it like a spot

This causes scarring and infection.

10. When to See a Dermatologist

Seek help if you have:

  • Large, painful bumps
  • Repeated infections
  • Scarring
  • Ingrowns that don’t improve after 1–2 weeks

You may have pseudofolliculitis barbae, which needs targeted treatment.
