Start with the manual for your exact ReHair laser comb. This guide helps you identify the device, prepare your questions and keep a useful use record. It does not provide a universal treatment schedule: session length, frequency, movement and precautions must come from the matching instructions.
1. Identify the model before choosing instructions
- Compare the product name on your order with the label on the device.
- Record the model or identifying code and retain the order reference privately.
- Check that the manual names the same device or explicitly covers your variant.
- Do not use instructions for a laser cap, brush or a similar-looking comb as a substitute.
2. Read the full routine once before starting
Locate the sections on intended use, warnings, power equipment, preparation, placement, movement, session timing and cleaning. Check what the controls or indicators mean. Reading the whole sequence first helps identify a missing step before you start, rather than guessing partway through a session.
3. Resolve missing or conflicting details
If the manual is absent, unreadable or inconsistent with the device, send ReHair support the product link, model information and your order reference. For example: "Please send the instructions matching this model and confirm the session duration, frequency, movement sequence, cleaning method and applicable warnings." Attach a clear label photo if needed, without sharing order details publicly.
Common questions
Can I use the timing from another website?
Not unless it is the official instruction for your exact model. A different device may have different output, controls or placement requirements. A research study schedule is also not automatically the schedule for a commercial product.
What if I miss a session?
Look for missed-session guidance in the manual or ask the manufacturer. Do not invent a catch-up routine, double the duration or combine schedules from several sources.
What if it does not turn on or behaves unexpectedly?
Consult the matching troubleshooting instructions and contact support if the issue is unresolved. Avoid opening the housing or trying an unspecified power supply. For discomfort or a new scalp concern, stop the session and seek appropriate advice; do not continue just to complete a timer.
What should I record?
Keep the model, date, use according to the manual and any questions in a short log. Record other changes in your care separately. A log helps explain your experience; it does not prove that a device caused a change in hair growth.
Get the right product information
The ReHair home-use comb listing is a starting point for identifying the current item. Exact instructions remain necessary even when the product name looks familiar. Once you have the manual, keep it with the device so future sessions use the same verified reference.
