What is Electrolysis?

Electrolysis is a method of permanent hair removal where a tiny probe delivers electrical current into each hair follicle. This process disrupts the follicle's ability to produce new hair. It is the only FDA-approved method for permanent hair removal and is effective for all skin and hair types.

What electrolysis can help with

  • ✓ Electrolysis may help with:
  • ✓ permanently removing unwanted hair
  • ✓ targeting fine, light, or stubborn hairs
  • ✓ shaping small, detailed areas like brows
  • ✓ treating hair that laser cannot effectively target
  • ✓ reducing long-term grooming needs

What to expect during your electrolysis appointment

A session lasts 15–60 minutes depending on the area. The provider inserts a fine probe into each follicle and delivers a brief electrical pulse before removing the hair. You may feel a quick heat or tingling sensation. Redness afterward is normal and typically fades within hours.

What results can you expect with electrolysis?

Results develop gradually as each follicle is treated repeatedly through different growth cycles. With consistent sessions, treated hairs become finer and eventually stop returning. Electrolysis is very effective for permanent removal, especially in small or stubborn areas.

How long electrolysis results last

Electrolysis provides permanent results once all follicles in the area have been treated through their full growth cycles. This may take several months or longer depending on the area and density of hair.

Who's a good fit for electrolysis?

Electrolysis is ideal for individuals seeking permanent hair removal, especially for hairs that are too light or fine for laser. It’s a great option for facial hair, small patches, and detailed areas requiring precision.

Alternatives to electrolysis?

  • Alternatives or complements include:
  • Laser hair removal for large areas
  • Sugaring for gentle temporary removal
  • Waxing for immediate results
  • Dermaplaning for fine facial hair

Common electrolysis questions

How does electrolysis work? +
Electrolysis works by inserting a fine probe into the follicle and delivering a controlled electrical pulse that disrupts hair growth. Once the follicle is disabled, the hair will not return. This makes electrolysis a highly effective permanent solution.
Does electrolysis hurt? +
You may feel quick heat or tingling during each pulse. Sensitivity depends on the area treated and your personal tolerance. Providers can adjust intensity for comfort or use numbing methods if needed.
How soon will I see results? +
Some hairs stop returning quickly, while others require multiple treatments through different growth phases. Over time, treated areas show visibly reduced density until hair stops growing entirely. Patience is key for full permanent results.
Is there downtime after electrolysis? +
Mild redness or swelling may appear but typically fades within hours. Most people return to normal activities immediately. Gentle aftercare helps soothe the skin post-treatment.
How many sessions will I need? +
Permanent results require repeated treatments due to hair growth cycles. Many people need sessions over several months. Exact timing varies depending on hair density and area size.
Is electrolysis safe for all skin and hair types? +
Yes—electrolysis is effective regardless of hair color or skin tone. This makes it ideal for hairs that laser hair removal may not target effectively.
Can electrolysis be combined with laser hair removal? +
Yes—many people use laser for larger areas and electrolysis for fine detail work. Electrolysis can finish areas where laser is less effective.
What should I avoid after electrolysis? +
Avoid heat, sweating, exfoliants, and sun exposure for 24–48 hours. Keeping the area clean and moisturized helps prevent irritation.
