How does a laser act on a hair follicle?<\/h2>\n

Hair melanin absorbs light, producing heat that acts on the follicle. Melanin in skin makes protection of surrounding tissue important.<\/p>\n

How do the three main types differ?<\/h2>\n

Common wavelengths are alexandrite 755 nm, diode around 800\u2013810 nm and long-pulsed Nd:YAG 1064 nm. Nd:YAG is often considered for darker skin; selection remains individual.<\/p>\n

Do more wavelengths mean a better result?<\/h2>\n

Offering several wavelengths in one handpiece is an engineering feature. Their number alone cannot establish benefit, safety or superiority over another device for a particular patient. Assessment requires the exact model, its intended use and relevant evidence. \u201cAlexandrite laser\u201d and \u201calexandrite wavelength\u201d are not complete synonyms: a wavelength specification does not establish that a device uses an alexandrite crystal as its laser medium.<\/p>\n

Why is one session not the final answer?<\/h2>\n

Results vary with hair and skin characteristics. Maintenance may be needed; permanent disappearance of every hair is not guaranteed.<\/p>\n

Which risks should we understand?<\/h2>\n

Risks include redness, swelling, discomfort, burns, scarring and pigmentation changes. Appropriate eye protection and consideration of tanning are necessary.<\/p>\n

What should we ask during consultation?<\/h2>\n

Discuss medicines, a tendency to scar, herpes and recent tanning during consultation.<\/p>\n

How should we read a device description?<\/h2>\n

Find the exact model and technology in the catalogue, but do not turn a specification table into your personal treatment plan. Wavelength, screen or cooling-system branding alone cannot establish effectiveness for your skin and hair. Clinical assessment and technical documentation answer different questions. This article helps separate those questions so a choice can be discussed through understandable reasons rather than advertising terms alone.<\/p>\n

How can we compare two offers?<\/h2>\n

Use the same initial questions when comparing clinics. What counts as success: fewer hairs, slower growth or a particular area remaining clear for a period? When will that outcome be assessed, and by whom? A session price or device name cannot answer these questions. Ask for expected benefit and uncertainty to be explained separately. Informed choice depends on knowing both what is offered and what is not promised.<\/p>\n
