Hair loss is complicated. Finding a solution shouldn’t be.

We're committed to seeing you get the best results possible and when you make a purchase on our site, we want you to be confident that we’re the last brand you’ll ever have to try.

Our products have been designed to focus on two things: results and safety. We've tested it. Our customers have tested it. And while we’re happy to report that 97% of women in our clinical study reported thicker, fuller, or healthier hair in 6 weeks, we don’t want to overlook the 3% of customers that may have limited compatibility with our products.

We’re here to ensure your journey back to thicker, healthier hair is successful, no matter what.

Our Guarantee is Simple

We're confident that you’ll see thicker, healthier, or fuller-looking hair within 60 days and bolder brows within 90 days. If we both can't see the start of incredible results, we’ll give you your money back. To remain eligible for this powerful moneyback guarantee, just follow these simple steps:

For Hair:

  1. Take high-resolution ‘before’ photos on Day 1 - the more angles, the better! It’s challenging to notice day-to-day changes in your hair. Taking pictures that track your journey along the way will also help document the incredible progress you’re making.
  2. Use at least 2 full bottles of either the Hair Revival Serum or Growth Concentrate (or both together!) over a period of at least 60 days, applying daily as directed.
  3. After 60 days of consistent use, take high-resolution photos of the same area(s) taken on Day 1.

For Brow:

  1. On Day 1, take a high-resolution, close-up ‘before’ photo of your brows in good lightning. We recommend you don’t apply makeup for this photo, as this will show your true progress along the way!
  2. Apply daily as directed for 90 days—one tube lasts about 3 months.
  3. After 90 days of consistent daily use, take another high-resolution, close-up photo of your brows in similar lighting as the initial photo.

Don’t see results (reduced shedding, the start of new baby hairs, etc.)? We can provide you with a prepaid return label upon reaching out to us at (see below for more details)

If you want to start the refund process, submit your original, uncropped, unedited before and after photos after the indicated 60- or 90-day period to our team at Our mission is to help each and every person win their individual battles against hair loss. So along with your pictures, please tell us your story. Let us know your morning and nighttime routines, your hair care regimen, and the results you were trying to achieve with our product—anything that can help us to continuously improve our products for you.

Photos should be clear, with similar hairstyles, in similar well-lit settings, and at similar angles. Photos should include tight hairstyles to show the same hair part and hairline, and should capture the entire area of concern. Hair should be clean and dry for photos. If you are unsure whether or not your pictures meet this requirement, feel free to send us progress pictures along the way at so we can support you along your journey.

After submitting, please allow 5-7 business days to process your request and issue your pre-paid return label. After receiving the label, return your empty bottles to us and we'll process your refund as soon as we receive them. Refunds will be processed to your original payment method. If your original method of payment is no longer available, we'll gladly issue you online store credit. Any unopened,r unused product can be returned per our returns policy

Note: Our money back guarantee is one-of-a-kind. We want you to feel at ease giving your hair the time it needs to ‘reboot.’ Therefore, we will gladly offer you a full refund, but only after you’ve been able to use our product for at least the specified (and data-backed) 60- and 90-days. Our moneyback guarantee will be honored any time after the 60-day (hair) and 90-day (brow) period up to 120 days after purchase. Our product takes time to work, therefore any claims placed before 60 days will not be eligible for a refund, and will invalidate refund eligibility. Accessories are not eligible for refund. Our guarantee covers the daily use of 1 bottle of either Hair Revival Serum or Growth Concentrate per month per customer, up to 3 bottles in total.
