Frequently Asked Questions
How it works
Thinx Teens undies absorb your flow, control odor, wick moisture, and prevent leaks — so you can feel fresh, dry, and comfy! No pads, tampons, or other period products needed. Check out our Product Info page to — you guessed it — learn more about how Thinx Teens work! And if you want to learn more about how *periods* work, we’ve got a page for that, too.
Yup! Our period underwear is washable and reusable. Just machine wash cold and hang dry before first wear, then after each use.
Each pair of Thinx Teens period-absorbing underwear holds up to 5 tampons of flow to support early, inconsistent first periods. No other period products are needed.
Our leak-absorbing underwear features 3 layers of ultra-thin technology built into the center panel of the underwear — an innermost moisture-wicking layer, a super absorbent inner lining, and an outermost layer that acts as a leak-resistant barrier that leaves you feeling fresh and dry.
The built-in lining features 3 absorbent layers within the center panel of the underwear. It sits under the front of the vulva with leak protection that extends throughout the back of the underwear.
Nope! Our underwear is ultra-thin with built-in technology for absorbency without bulkiness. It features a moisture-wicking barrier to prevent wetness, ensuring you stay fresh and dry.
We've got you covered! The built-in lining of the underwear is intrinsically absorbent, wicks away moisture, and controls odor — leaving you feeling fresh and dry.
Our period-absorbing underwear handles blood clots similarly to a pad. Although the undies can't absorb the blood clot, they will absorb the surrounding moisture so you will not feel damp, wet, or uncomfortable.
Toxic Shock Syndrome (TSS) is associated primarily with tampon use. Period-absorbing underwear is a safer alternative.
Thinx underwear is safe. Per- and polyfluoroalkyl substances, also known as PFAS, are absolutely not part of our product design and we do not treat our finished products with PFAS. We also take measures to help ensure these substances are not added to our products through material, design, production, facility, and supplier controls. We care deeply about the materials used in our products, putting comfort and safety at the core of our design, development and manufacturing.
Our sustainable period-absorbing underwear is ultra-absorbent, odor-controlling, and moisture-wicking, designed to keep you fresh and dry. If your undies have not reached capacity, we recommend changing them once daily, as you would regular underwear. If your period begins to smell different (unusually fishy), that might mean something is amiss down there, and it might be a good idea to check in with your doctor.
Our period-absorbing underwear is 100% latex-free! Our elastane is composed of a long-chain polymer known as polyurethane, known in technical circles as a polyether-polyurea copolymer, used for having breathable and water-resistant qualities. Elastane is an entirely synthetic fabric; it does not exist anywhere in nature nor contains organic materials. So, no latex! However, a number of our styles do feature exposed elastic.
Yes! We don’t apply any perfume or fragrance to any of our materials. All of our products are fragrance-free!

Periods 101
Your period is one phase of your menstrual cycle, which in total typically lasts 21 to 45 days. The ~flow~ of blood and tissue you experience (your period!) happens about halfway through that cycle. Roughly once a month, beginning at puberty, your body prepares for an egg to be fertilized (possible pregnancy). During this time, the lining of your uterus thickens around the egg. When you don’t become pregnant, your body sheds the built up lining of the uterus that it no longer needed and releases the unfertilized egg. This is referred to as menstruation, or what we call a “period" — menstrual blood and tissue flow from your uterus through the small opening in your cervix and pass out of your body through your vagina.
*Every body* is different, and it’s no big deal to get your period before or after your friends. Some people get their first period as early as 8 or 9 years old, others get them as late as 16. First periods often happen around the same time in life for people who are related to one another, so if you can, ask someone related to you with a period when they got theirs to get some idea of when you’ll get yours.
Ovulation refers to the phase of your cycle when an egg is released from the ovaries. Pregnancy occurs when an egg is fertilized by sperm. When an egg isn't fertilized by sperm, your body sends the signal that you're not pregnant and begins getting ready to shed the uterine lining. A couple weeks after ovulation, you'll get your period, which is how your body naturally flushes out blood, mucus, and tissue out of your cervix. This cycle repeats itself every month.
*Every body* is different! You may feel a little wetness (more than usual vaginal discharge) or you may not feel your period flow at all, instead you’ll just notice some color on your undies.
The amount of time you’ll bleed every month can vary from 3 to 7 days, but it’s normal for your period to vary a little from cycle to cycle. If you notice blood for longer than 7 days, it’s a good idea to check with your doctor to make sure everything is okay.
Every period is unique. Many things can affect the frequency in which you get your period such as stress, hormones, pregnancy, or even medications such as birth control, but the average period occurs monthly or every 28 days. Some cycles can even be longer or shorter than this –– which is normal too! You can always check with your doctor if you think something is amiss with your cycle.
On average, you lose 2 to 7 teaspoons of menstrual fluid while on your period. That might seem like a lot, especially when you're changing your period products, but that's because menstrual fluid is made up of a bit more than just blood. Menstrual fluid is actually a combination of blood and tissue from your uterine lining, which is also why you might notice clots or other textures that differ from a regular cut. If you’re ever concerned that you’re losing too much menstrual fluid, check-in with your doctor to make sure everything is okay, or ask an adult to help you set up an appointment.
Periods come in all different colors and textures — some are more red and liquidy, others may be brown and clumpy. Brown blood is just blood that’s a bit older. Some people notice brown blood before they see red (on or before day 1), others have brown blood at the end of their period (day 5, or whenever your period ends). If you’ve just started your period, you may only see brown stuff, and that’s totally normal.
Periods are different for *every body* and yours can even be different from cycle to cycle. You may start with a light flow, have heavy days in the middle, and finish off with a light flow; or have heavy flows at the beginning and then lighter days only at the end; or something else! You’ll get to know *your* flow over time and understand what heavy, moderate, and light days mean for you.
Absolutely! You can do *anything* on your period — swim, dance, play sports, wear white pants, whatever — but the period product you use may change depending on the activity. Thinx Teens is flexible period protection for whatever you do on land. However, we don't recommend using our products underwater.
Your period is just one phase of your menstrual cycle, which in total typically lasts 21 - 45 days. The ~flow~ of blood and tissue you experience (your period!) happens about halfway through that cycle.
PMS, or premenstrual syndrome, is often defined by the physical and emotional symptoms you may feel before you get your period. The fluctuation of estrogen and progesterone hormones is responsible for symptoms such as cramps, bloating, sore boobs, fatigue, moodiness, breakouts, diarrhea, nausea, headaches, irritability, mood swings, food cravings, anxiety, and more (fun, we know!). PMS symptoms often show up a few days before your flow begins and can function as helpful signs to let you know when to keep your period undies on hand!
Periods are 100% normal and nothing to be ashamed about! It may feel super-awkward, but it doesn’t have to be. For some it’s easy to blurt this kinda stuff out, others find it is easier to write a note or send a text. Your friends or any adults you trust can be a helpful support system when you need assurance or advice.
Who you decide to share your period with is your choice, but in many cases sharing with someone you trust is helpful and can lead to some really awesome tips on what products to use and how to feel better if you have PMS symptoms. Periods are nothing to be ashamed of or hide!
We’re so glad you asked! Not all bodies experience periods, only bodies with uteruses. These bodies produce certain hormones (naturally-occurring chemicals in our bodies) that make a menstrual cycle happen, which is a fancy way of saying that they make a period happen. Bodies without uteruses (such as bodies with penises) don’t experience periods because they don’t have a uterus.
Periods begin at puberty, between the ages of 8 and 16. and last until you enter what’s called menopause. This happens for most people between the ages of 45 and 55, and, like your period, menopause will come with some new physical and emotional changes. Fun, we know!

Caring for your undies
Our underwear is super easy to care for. Toss them in with the rest of your laundry on a cold cycle before first wear and after each use — your other clothes will be fine! Steer clear of fabric softener and bleach. Hang dry to keep your undies at max performance (but, if you accidentally dry them once or twice, it’s not the end of the world). Do not iron. Check out our How to Wash page for more information and helpful tips!
Machine wash your underwear on cold to keep them in tip-top shape. The standard cold wash is 60-80 degrees Fahrenheit (15C - 27C). If you're hand-washing, the water should feel close to room temperature.
Yep! Washing our leak-absorbing underwear with your other laundry is perfectly hygienic, and your other clothes will be fine. Washing machines will dilute the contents almost immediately, and your other clothes will not stain if you're washing on cold.
We discourage using fabric softener because it breaks down the fabrics in the center panel of the underwear and the bonding around the seams, which helps absorb and keep leaks in. Over time, fabric softener will make the underwear less absorbent.
Drying times may be affected by humidity levels and the airflow of the space you hang them in. Under non-humid conditions, moderate absorbency styles typically dry within 10-12 hours and super absorbency styles typically dry within 19 hours.
Don't panic — a few cycles in the dryer won't hurt your period-absorbing underwear. However, repeated exposure to the heat from dryers or irons will affect the underwear's elasticity, which helps prevent leaks, so don't make it a habit!
Pro tip: Use a mesh laundry bag to separate them from your other clothes for easy removal from the wash while the rest goes in the dryer.Our absorbent underwear isn’t stain-proof, although the materials used in our absorbent gusset are largely stain-resistant. Plus, they’re lined in black to prevent stains from showing. To further prevent stains, follow our washing instructions.
Follow our simple care instructions to keep your period-absorbing underwear at maximum performance. Replace them at 30 washes.
You can recycle our leak-absorbing underwear when you’re finished with them. Just wash them until they’re squeaky clean. Then, cut out the absorbent gusset and dispose of it. The remaining fabric can be donated to your local textile recycling bin.

Give $10, get $10
Our referral program is one way for you to spread the Thinx Inc. love! If you refer a friend, they get $10 to spend on any Thinx Inc. product (Thinx for All Leaks, Thinx, or Thinx Teens). If they make a purchase, you also get $10 in credits. You can earn up to $500 in Thinx inc. credit by referring up to 50 friends. To get started, sign up or log in to your account. Share your unique referral link directly or through email, SMS, WhatsApp, or Facebook!
Yes — you can earn up to $500 in Thinx inc. credit by referring up to 50 friends. After that, your friends who are new customers will keep receiving $10 promo codes but you will not accrue any more credits on your account.
For every new customer, you refer, you will earn a $10 credit to apply toward any Thinx Inc. purchase (Thinx for All Leaks, Thinx, or Thinx Teens). So, if you refer three new customers, you'll have $30 to spend. You can use your credits all at once or split your credits across orders until you use all credits.

You can only refer new customers.
If you’re referring a friend, your $10 in credits are unlocked in one week (after they make a purchase) as long as the order isn't canceled. If you're a new customer referred by a friend, you can use your referral code immediately to get $10 off your first order of $35 or more.
Unfortunately, if your referral cancels their order, you won’t receive the $10 credit.
Yep! At checkout, you can decide how many credits you want to apply to your order. You can apply them all at once or just use some of them and save the rest for later.
Yes, they can be used on any product at thinx.com.

About us
We aim to create underwear that champions and supports bodies throughout different stages of life. From your first period to post-menopause and all the leaks in between. We aim to empower our customers with sustainable solutions while breaking taboos around bladder leaks and menstruation.
Body literacy is understanding the body and its functions, so that we can be more empowered when it comes to our health and wellness. Without body literacy, there is a rise in misinformation, stigmas, and shame around our bodies and its normal functions. At Thinx, we believe in challenging societal stigmas and giving more people access to body education. That’s why we created GetBodyWise.
Menstrual equity refers to equal and comprehensive access to menstrual hygiene products and the right to reproductive health education. Thinx actively supports menstrual equity by offering educational content and partnering with like-minded organizations to bring leak protection products to communities that need them most. Through our GetBodyWise program, we're working to fight societal stigmas and help empower more people with body literacy.
