What should you know about full leg laser hair removal?

The device delivers light absorbed by pigment in the hair shaft. Heat travels toward the follicle and can limit its ability to produce another hair. Because follicles cycle through active and resting phases, one visit cannot treat every follicle equally. Hair may shed after treatment, while later growth can become finer or less noticeable. Alexandrite, diode, and Nd:YAG devices have different light wavelengths; the appropriate choice depends on your skin tone, hair colour, and the clinician’s assessment. Laser is generally less useful for very light, grey, or white hair.

Tell the clinic about recent tanning, pigment changes, medicines, skin conditions, and any tendency to form raised scars. Avoid tanning and follow the clinic’s instructions about sun protection. Shave rather than wax or pluck before an appointment if instructed, because the follicle needs to remain present for the light to target it. After treatment, temporary redness or warmth can occur. Use gentle cleansing, avoid picking the area, and protect treated skin from strong sun. Ingrown hairs may improve when shaving is reduced, but active irritation should be discussed before treatment.

Contact the treating clinic if swelling, blistering, marked pain, crusting, or dark or pale patches develop instead of settling. Seek prompt medical advice for spreading redness, pus, fever, or increasing tenderness, which can suggest infection. A consultation is also sensible when excess facial or body hair appears with irregular periods or other hormonal changes, because hirsutism may need assessment before cosmetic treatment.

Which laser wavelength suits my skin tone and hair colour? How should I prepare if I recently used a self-tanner or had sun exposure? What reactions should I expect, and which symptoms require review? Should an underlying condition be assessed before treating widespread or new hair growth?
