Yes, you can use hair clippers without a guard, but it requires caution and specific techniques. Here's what you need to know:

■When to Go Guardless

1.Skin Fades or Tapers

Use case: Creating ultra-short transitions near the neckline, temples, or sideburns.
Technique: Hold clippers at a 30° angle away from the skin to avoid cuts.

2.Hard Part Lines

Use case: Shaving sharp part lines (e.g., undercuts).
Technique: Use the corner of the blades only—never the full blade width.

3.Spot Correction

Use case: Fixing uneven patches missed by guards.
Technique: Lightly "flick" blades outward (don’t press into the scalp).

■Critical Risks

1.Instant Bald Spots

Bare blades cut hair to 0.2–0.5mm (near bald). One slip creates irreversible patches.

2.Skin Irritation/Cuts

Blades can scrape moles, acne, or sensitive skin. Never use on bony areas (crown, hairline).

3.Uneven Results

Without guard guidance, it's easy to cut deeper in some spots than others.

■Pro Techniques If Guardless

1.The "Flick" Method

Place blades flat against the head → Cut upward → Flick wrist outward at the end.
Prevents lines and blends into longer hair.

2.Lever Adjustment

Lever DOWN: Shortest cut (use for skin fades).
Lever UP: Leaves ~1mm buffer (safer for beginners).

3.Taped Blades Hack

Apply one layer of electrical tape over blades to mimic a "000" guard.

4.When to NEVER Go Guardless

Curly/Coarse Hair: Higher risk of ingrown hairs and irritation.
Scalp Conditions: Dandruff, psoriasis, or sunburned skin.
DIY Back/Side Cuts: Impossible to see angles—guaranteed unevenness.

■Safer Alternatives

1.Shortest Guard (#000 or #0.5)

Cuts to ~0.5mm—close to bare blades but safer.

2.Trimmer for Edges

Use a dedicated trimmer (not clippers) for sharp lines.
