How many times can period underwear be washed?
Period underwear can typically be washed and reused 50 to 100 times, depending on the brand, material quality, and how well you care for them.
That means with proper care, a single pair can last 2 to 4 years — making it a cost-effective and eco-friendly alternative to disposable menstrual products.
🧺 What Affects How Long Period Underwear Lasts?
✅ 1. Quality of the Brand
-
High-quality brands like Thinx, Aisle, and NYX Collection use durable materials that hold up through frequent washes.
✅ 2. Proper Washing and Drying
-
Washing in cold water and air drying (instead of using a dryer) helps preserve the fabric and absorbent layers.
-
Skipping fabric softeners and bleach is essential — they break down absorbent technology.
✅ 3. How Often You Wear Them
-
If you have only 1–2 pairs and wear them constantly, they’ll wear out faster.
-
With a rotation of 4–5 pairs, you can extend the life of each one.
