The recommended frequency for washing jeans varies depending on factors like wear, activity level, and personal preference, but general expert consensus suggests washing jeans sparingly to preserve their color, fit, and durability.

• Levi's advises washing jeans after about 10 wears unless they are visibly dirty or start to smell, recommending spot cleaning in between washes to maintain unique creases and fades

• Some denim enthusiasts wash their jeans as infrequently as every 2-6 months, especially raw denim, to preserve the natural aging and fading process

• Dermatologists recommend washing jeans every 3 to 5 wears to balance hygiene and garment care, especially if you sweat or wear lotions that can accumulate in the fabric

• Practical user experiences vary widely: some wash jeans monthly or every 3-10 wears, while others wait until the jeans fail the "sniff test" or become visibly soiled

• Washing jeans less often extends their lifespan and is more environmentally friendly by reducing water and energy use

• A good rule of thumb is to wash jeans every 3-10 wears or about every 5-6 weeks if worn regularly, but always wash sooner if they smell or are dirty

In summary, washing jeans about every 5 to 10 wears or every few weeks to months is typical, with spot cleaning and airing out between washes to maintain hygiene and preserve the jeans' quality.
