Editorial update: September 12, 2026. Published by ReHair.
Use the instructions supplied for your exact ReHair comb model. We cannot provide a verified universal session length, frequency, wavelength or time per scalp area from the information available for this revision. The conflicting schedules in the older article have been removed rather than replaced with another guessed routine.
Before the first use
- Identify the model from the device label and your order record.
- Match it to the instruction manual and check the intended use and warnings.
- Confirm the supplied power equipment and any preparation or cleaning requirements.
- Read the directions for placement, movement, session duration and frequency.
- If anything is missing or contradictory, ask support before use.
Do not borrow another device's routine
A schedule for a cap, brush, different comb or different brand is not a substitute for your manual. Do not increase exposure to pursue faster results, combine timings from several articles or guess how to compensate for a missed session. Follow model-specific precautions rather than treating a blog as safety clearance.
What to send support
When you contact ReHair support, provide the product name, order reference and model information from the label. Ask for the matching manual and clarification of the specific step you cannot verify. Avoid posting order details publicly. The current comb listing can help identify the item, but it does not replace missing instructions.
Keep expectations realistic
This guide does not claim that a comb treats every cause of hair loss or has no possible adverse effects. If you have concerns about suitability, medicines or scalp symptoms, discuss them with a qualified clinician. Keep the manual available and follow its stop-use and troubleshooting guidance if a problem arises.
