Maintaining the Weight Line in a Bob

A bob relies on a precise weight line to maintain its shape. When heat styling is performed incorrectly, hair often flips outward or loses the density required to hold that crisp perimeter. The goal is to preserve the bluntness of the cut while smoothing the surface texture.

This process requires minimal equipment and a focus on controlled tension. By avoiding high-heat tools at the ends, you maintain the density necessary for the hair to drape correctly.

1. Section the hair. Divide the hair into four clean quadrants. Start by creating a center part, then section from the crown to behind each ear. Use flat clips to secure each section away from the ends to prevent creasing.
2. Apply a heat protectant. Distribute a lightweight thermal protectant evenly through damp hair. Focus on the mid-lengths, ensuring the ends receive only the remaining residue. Excess product on the ends will create unnecessary weight and cause the bob to separate.
3. Execute the tension blow-dry. Use a boar-bristle round brush with a small diameter to match the curve of the nape. Pull the hair straight down with consistent tension, keeping the dryer nozzle pointed downward. Stop the dryer three inches before reaching the ends to prevent over-drying the weight line.
4. Set the ends with a paddle brush. Once the hair is 90 percent dry, switch to a paddle brush. Use the flat side of the brush to smooth the ends downward, allowing the natural weight of the hair to anchor the shape. This technique prevents the ends from curling upward.
5. Final polish. Apply a single drop of finishing oil to your palms. Smooth your hands over the surface of the hair once to tame flyaways without breaking the structure of the weight line. Avoid the perimeter entirely to ensure the bob retains its bluntness.

The health of a bob is defined by the weight of its ends.
