Trim the hair on the sides and back to match your natural growth pattern
Use a neckline guard or “no-neck” guideline to keep the back shorter than the bulk at the crown
Layer or taper the top and sides to reduce the rounded “helmet” shape
Ask for a shorter, cleaner line around the jaw and cheek area to avoid bulk at the sides
Style with a blow-dryer and a round brush to add lift at the roots
Use a matte clay or paste and apply from roots to mid-length, then lightly shape the top
Avoid heavy waxes that flatten and emphasize the bob shape
Brush through while drying to smooth and direct hair outward and upward
Get regular trims every 3–6 weeks to prevent the shape from returning
If it’s a specific barber term, ask for “a scissor cut with a tapered back and sides” or “short back and sides with a layered top”
Consider growing it out evenly rather than letting sides and back lag behind
If you want it gone quickly, choose a short cut (crew cut, buzz, or short textured crop)
