Clear the path
Start with clean, dry hair and expose the intended scalp area as your instructions describe.
START WITH THE AREA YOU NOTICE
These common areas can help you explore relevant information. They are not a diagnosis.
CHOOSE YOUR FORMAT
Use a laser cap for broader, hands-free scalp coverage. Choose a handheld comb or brush when you want targeted placement along the hairline, crown, or part lines.
HOW IT WORKS
ReHair devices deliver low-level red laser light to the scalp. Research on low-level laser therapy has reported improvements in hair density for some adults with androgenetic alopecia.
Category-level evidence does not guarantee a result from every ReHair model or for every person. Follow the instructions for your exact device.
PRODUCT ENGINEERING
Explore the cap shell, flexible interior, laser-diode layout and wired power system. Tap each marker for a closer look at the current ReHair product photography.
The black outer shell keeps the format familiar and wearable, while the treatment hardware sits inside the cap.
Current ReHair product information describes the diode system as mounted inside a flexible, dome-shaped membrane.
The current cap is offered in 88-, 160- and 272-diode configurations. Select the coverage level on the product page.
The current product specification lists a wired connection and AC adapter. Follow the instructions supplied with your exact model.
FITS INTO YOUR DAY
Choose a calm part of your day—reading, working or taking a break—and use your ReHair device only as directed for your model.
HOW TO USE
Follow the instructions supplied with your exact model. Prepare, use, then power down and store.
WHAT TO EXPECT
Hair growth is gradual and individual. Follow the schedule for your model, use it consistently, and compare photos under the same conditions over time.
Correct timing and frequency matter more than adding extra sessions.
Hair changes are gradual; avoid judging progress from day-to-day variation.
Match lighting, angle, distance and hair part at each check-in.
Individual results vary. If hair loss is sudden, patchy, or concerning, seek qualified advice.
BEFORE & AFTER
BASELINE
FOLLOW-UP
CAP VS COMB
Both formats support a directed light-therapy routine. The better fit depends on where you want coverage and how you prefer to use the device.
LASER CAP
LASER COMB
Shared principle: Use only as directed for your model. Session timing and frequency vary by device.
EVIDENCE STANDARDS
Research can explain a category. A ReHair product claim should still match the exact model, document and sales region.
Use broader studies to explain the technology—not to guarantee an individual result.
Names, variants, reports and instructions should refer to the same device and region.
Stories should be traceable, consented and published with relevant context.
FAQ
Start with the instructions for your exact ReHair model. These answers explain the decision path—not a diagnosis or a substitute for professional advice.
Choose a Cap when you want broader, hands-free scalp coverage. Choose a Comb when you prefer targeted, hands-on placement. Compare the current products in each format, and contact us if fit or coverage is unclear.
Use only the session time and frequency in the instructions for your exact ReHair model. Schedules can differ by device, so do not borrow a routine from another model or increase use on your own.
Do not change or stop a prescribed treatment on your own. If you use medication, a topical product, a supplement, or another device, ask your doctor or pharmacist whether the routines can be combined and how to sequence them.
Do not guess. Review the safety instructions for your exact model and ask a doctor or pharmacist before use if you have a known light-sensitivity condition, an eye or skin condition affected by light, or take medication that may increase light sensitivity.
Switch the device off and disconnect it from power first. Follow the model instructions for cleaning; keep the device and controller dry, and do not immerse them or use solvents unless the instructions specifically allow it. Store away from heat, moisture, and cable strain.
There is no single date that applies to everyone. Hair-loss cause, starting point, consistency, and other routines can all affect what you notice. Use the same lighting, angle, hairstyle, and interval for progress photos instead of relying on day-to-day impressions.
Seek professional advice when hair loss is sudden or patchy, the cause is unclear, or the scalp is painful, burning, intensely itchy, red, scaly, swollen, or has sores. A dermatologist can help identify the cause and advise whether a device belongs in your plan.
The current Warranty page lists a 1-year limited warranty against defects in materials and workmanship. The current Returns & Refunds page says return requests must be made within 7 days of receiving the order and sets condition and packaging requirements.
