Final answer:
If hair is still remaining after waxing, the best option is to tweeze the remaining hairs.
Step-by-step explanation:
If hair is still remaining after waxing, the best option is to tweeze the remaining hairs. This involves using a pair of tweezers to pluck out individual hairs. Applying more wax is not recommended as it may cause irritation or damage to the skin. Leaving the remaining hair untreated or shaving it will not effectively remove the hair from the root like waxing does.
