Unwanted facial hair: when “just make it stronger” is the wrong response

The face does not forgive automatic decisions. A client may notice new hairs and ask for a stronger treatment, while a practitioner may interpret them simply as insufficient energy. Growth also depends on hair diameter and pigment, the baseline map, at-home removal and factors that a laser practitioner does not diagnose. I therefore begin with a pause and a structured comparison.

Establish exactly what changed

Compare photographs taken under the same lighting, without make-up and at a similar interval after shaving. Record new areas, speed of appearance, hair diameter and colour. The client’s subjective impression matters, but support it with a reproducible record.

Ask about plucking, waxing and changes in medication, health and skincare. A practitioner does not infer a hormonal condition from a chin line. Document what can be observed and recommend medical assessment when growth changes quickly or is accompanied by other symptoms.

Distinguish terminal hair from vellus hair

Coarse dark hair and fine, lightly pigmented hair present different targets. Increasing energy cannot add melanin to light vellus hair. On the face, avoid expanding boundaries into fine neighbouring hair merely to create a sense of complete coverage.

Paradoxical hypertrichosis has been reported after light-based procedures, more often in certain anatomical regions. This is not a reason to frighten clients, but it is a reason to assess boundaries carefully and avoid promising benefit where the target is uncertain.

Choose the appropriate decision pathway

If the baseline map confirms suitable pigmented hair and the skin is calm, review technique, intervals and protocol within authorised limits. If fine vellus hair predominates, leaving it untreated may be the appropriate decision. If the change appears unusual, pause the course pending medical assessment.

No pathway starts with a remote prescription of settings. Device model, cooling, spot size, pulse duration and technique interact. A trained practitioner makes the decision after in-person assessment and under the device instructions.

• Comparable photographs and dates.
• Hair diameter, colour and the new boundary of growth.
• At-home removal and health changes.
• A clear decision: continue, narrow, stop or refer.

Explain a pause without blaming the client

“We need to understand this before continuing” is more professional than promising to fix everything with one stronger session. Give the client a copy of the observations and a specific question for their doctor, not the vague instruction to “check your hormones”.

After assessment, the plan may resume, change or end. A practitioner’s value is not measured by the number of procedures completed. Sometimes the most useful action is deciding not to press the button.
