* The type of twist: Smaller, tighter twists may require less length than larger, looser twists.
* Hair texture: Coarser or thicker hair may hold twists better at shorter lengths compared to finer or straighter hair.
* Stylist's skill: An experienced stylist can often create twists on shorter hair with the right techniques and products.
* Desired style: If you want the twists to hang down significantly, you'll need longer hair. For shorter, more compact styles, shorter hair may suffice.
If your hair is shorter than 2 inches, it may be difficult to create twists that will hold properly. Consult with a hairstylist who specializes in twists to get the best advice for your specific hair type and desired look.
