Return Policy

Returns

  • We accept returns of unopened, unused products that are not designated as “final sale” or “non-returnable.”
  • Items must be returned within 30 days of shipment.
  • To return products, you must obtain a Return Merchandise Authorization (“RMA”) number by sending an email to returns@wavebye.co. We will not accept returns without an RMA number.
  • If you request, we will provide a return shipping label and deduct $18.00 from your refund to cover return shipping costs and restocking fee. If you choose not to use our return shipping label, you are responsible for all shipping and handling charges on returned items, and you bear the risk of loss during shipment. We therefore strongly recommend that you fully insure your return shipment against loss or damage and that you use a carrier that can provide you with proof of delivery for your protection. 

Damaged products or broken tamper seals

  • If the product is damaged or if the tamper seal has been broken upon arrival, please contact us immediately at hello@wavebye.co with your name and order information. We will work with you to address the issue as quickly as possible.

Refunds

  • Refunds are processed within approximately five business days of our receipt of your merchandise (less the original shipping and handling costs). Your refund will be credited back to the same payment method used to make the original purchase through the Service.

The Category Hasn't Evolved

The period care category hasn’t meaningfully evolved in over 100 years. Today’s solutions are inherently reactive, treating pain only after it starts, rather than preventing it. Wave Bye introduces a new standard: a premenstrual, over-the-counter approach designed to be started before period onset, addressing the root cause of both pain and heavy bleeding before they begin.

The Opportunity

  • 22B Periods in the US are Undertreated

    The average woman experiences ~450 menstrual cycles, representing significant lifetime value and a meaningful opportunity for impact.

  • $15B Annual Market

    One of the largest categories in women’s health, spanning products, medications, and cycle management. Representing consistent, recurring spend across a large and underserved population.

  • 56% of Women Use OTC Medications Reactively

    Period care today is fragmented; split between reactive medication use and non-medical coping strategies like rest or heat. Around 50% of women rely on these approaches, with no clear path for earlier intervention.

Timing Changes the Outcome

The biological processes that drive cramping and heavy bleeding begin before a period starts. Unlike traditional products, Wave Bye is designed as a pre-dosed regimen to be taken during this premenstrual window—guiding users to start treatment earlier, with the goal of reducing symptom intensity.
