Electrology and laser hair removal: what to know

Electrology applies controlled electrical energy through a probe placed into a hair follicle. It can be used on individual hairs and on hair colours that do not respond well to pigment-based devices. Laser hair removal uses selected light energy; the light is absorbed more strongly by darker hair and converted to heat around the follicle. A session therefore covers a wider zone, but results vary with hair colour, skin tone, device, and treatment settings.

Temporary redness, swelling around follicles, or tenderness can occur after either method. Darkening or lightening of treated skin and scarring are possible skin reactions, particularly when settings, aftercare, or sun exposure are unsuitable. Hair reduction is gradual because follicles respond at different growth stages.

Choose a trained practitioner who assesses the treatment area, skin tone, hair pattern, medicines, and history of abnormal scarring. Ask which device or technique is proposed and how the skin will be protected. Avoid tanning before and after light-based treatment, follow instructions about shaving or stopping other hair-removal methods, and do not pick at crusts or bumps.

If unwanted hair is sudden, widespread, or accompanied by irregular periods, voice change, or acne, discuss possible hirsutism with a clinician before focusing only on removal. Recurrent painful lumps in hair-bearing folds may need assessment for hidradenitis suppurativa.

Contact a clinician if redness spreads, pain worsens, blisters develop, pus appears, fever occurs, or marked colour change persists. Seek prompt care for swelling around the eyes, breathing difficulty, or a rapidly worsening reaction. A dermatology review is also sensible when repeated ingrown hairs or razor bumps are leaving scars.

Which method fits my hair colour and skin tone? What preparation should I stop, and how will you reduce the chance of burns or pigment change? How will you manage a flare of ingrown hairs or an underlying hair-growth condition?
