How long does a traditional perm last?

A traditional perm typically lasts between three and six months, though the exact timeline depends on your hair type, how fast your hair grows, and how well you care for it at home. The best way to get a precise estimate is to have a stylist assess your hair in person.

What affects how long a perm lasts

Several factors determine how long your results hold up. Hair texture plays a big role — coarser hair tends to hold a curl pattern longer than fine hair. Porosity matters too. Hair that absorbs and retains moisture well is more likely to maintain the curl structure over time. Growth rate is another factor. As new straight roots come in, the overall look will begin to change, typically becoming more noticeable around the three month mark.

Curl tightness and style

The type of curl your stylist creates also affects longevity. Tighter curl patterns, set with smaller rods, tend to last longer because there is more structural change built into the hair. Looser styles like body waves start with a more relaxed pattern and naturally soften faster, sometimes within two to three months.

How aftercare extends your results

Consistent aftercare is one of the most controllable factors. Switching to a sulfate-free shampoo, deep conditioning weekly, and air drying instead of heat styling all help preserve the curl pattern. Skipping these steps can cause curls to loosen well before the three month mark.
