We give your hair the time it actually needs — or you get your money back.
Real hair growth doesn't happen in a week, and any brand that promises overnight results isn't being honest with you. A single hair follicle goes through a growth cycle measured in months, not days. That's why we don't offer a quick 30-day return that ends long before you could ever see a difference.
Instead, we give you a full 7 months (210 days) to use the Exy Red Light Cap consistently and judge the results for yourself. If you follow the protocol and still don't see a noticeable improvement, you can send it back for a refund. We're able to offer this because we've seen what the cap does when people actually give it the time — and we'd rather earn your trust than rush your decision.
Most guarantees are built to look generous while quietly expiring before the product has a chance to work. Ours is the opposite.
Androgenetic hair loss reverses slowly. The follicle has to move out of its resting phase, re-enter active growth, and push out a new, thicker hair — a process that realistically takes four to seven months of consistent stimulation. If we let you return the cap at month one or month two, you'd be making a decision before the science has even started to show.
So our guarantee is intentionally structured around the biology:
This isn't a catch — it's the point. The guarantee protects people who give the cap a fair chance, not impulse returns made before the product could possibly help.
After your cap arrives, register your device and upload a clear 'before' photo within 45 days of delivery. This single step activates your guarantee. Without it, you are not eligible for a refund.
Follow the recommended protocol every day. Your 210 days begin the day you receive your cap.
Take one progress photo or short video each month — 7 in total — with the date or metadata intact. This unlocks a full 100% refund instead of the standard 75%.
If you haven't seen a noticeable improvement, email us between day 210 and day 240 to start your return. We'll issue your return authorization and instructions.
If you registered on time, used the cap for the full 210 days, and request your return inside the 210–240 day window, you're entitled to a refund of 75% of your purchase price. A 25% service fee covers processing and restocking.
We'll waive the entire 25% service fee — giving you a full 100% refund — if you document your journey with 7 monthly photos or videos that include date stamps or metadata showing consistent use over the 7 months. Submit them when you request your return, and once verified, you get every dollar back.
In other words: give the cap a real, documented chance, and there is zero financial risk to you.
Register within 45 days of delivery to activate your 7-Month Growth Guarantee. Don't wait — registration is required for all refunds.
REGISTER YOUR DEVICE →We believe in the effectiveness of the Exy Red Light Cap and see the results our customers achieve. To ensure the best possible outcome, the product must be used consistently for the full 210 days as directed.
If you do not experience a noticeable improvement after 7 months of consistent use, you may return the cap for a refund of 75% of the purchase price (a 25% service fee applies). See the Risk-Free Growth Guarantee section below for how to have this fee waived for a full 100% refund.
To be eligible for any refund under this guarantee, you must:
This guarantee can be used only once per customer and applies solely to the Exy Red Light Cap. It does not apply to consumable items, accessories, or supplements.
We want you to shop with complete confidence. While the standard guarantee carries a 25% service fee, you have the opportunity to have that fee fully waived — making your purchase truly risk-free.
To qualify for a 100% refund, document your experience with the product by taking 7 photos or videos total — one per month across the 7-month period. Each photo or video must include a date stamp or metadata confirming when it was taken, and should clearly demonstrate your consistent use of the product over time.
When you request your return within the 210–240 day window, submit your documentation for review. If all requirements are met, we will waive the 25% service fee and process a full refund.
You must still register with a 'before' photo within 45 days of receiving your cap to be eligible. The monthly documentation is in addition to — not a replacement for — the initial registration.
Every Exy Red Light Cap includes a 2-year warranty against defects in materials and workmanship. To request warranty service, email us with your order number and a photo or short video showing the issue.
How to Start a Return: Email our refund department to request your return within the 210–240 day window. We'll review your eligibility and issue a Return Authorization (RA#) with the return address. Ship the cap with a postmark within 10 days of receiving your RA#.
