Oklahoma Barber Practice Exam

Scalp manipulations help to increase the flexibility of the scalp by manipulating and massaging the scalp muscles. This can help to loosen up any tightness and increase blood flow to the area. Choices A, C, and D are incorrect because they do not involve any physical manipulation of the scalp, which is necessary to improve flexibility. Additionally, option A (egg shampoo) may actually make the scalp feel tighter due to the protein in eggs, while options C and D (tar and antiseptic shampoos) are more focused on cleaning and treating the scalp rather than increasing flexibility.
