How can a barber prevent neck irritation during a haircut?

Using a neck strip before securing the cape is an effective method for preventing neck irritation during a haircut. The neck strip provides a barrier between the client's skin and the cape, which can sometimes cause friction or irritation due to the material or movement. By placing the neck strip securely around the neck, barbers can create a comfortable and clean environment for the client, minimizing any potential discomfort caused by the cape’s edges or static.

The other options might not address the root cause of neck irritation as effectively. Applying lotion to the neck could help in some cases, but it does not prevent friction from the cape or other potential irritants during the haircut. Using a softer cape material may provide some comfort, but it does not form a protective barrier like the neck strip does. Cutting hair shorter does not address neck irritation at all, as it pertains to the hair's length rather than the client's skin sensitivity during the service.
