Iowa Cosmetology Practice Exam

When placing hair on base, it is important to consider the direction and angle at which the hair is held. In this case, 45 degrees forward is the correct angle. Option B, 90 degrees straight up, would create a flat result. Option C, 45 degrees down, would create a more vertical result. Option D is incorrect as there is a specific angle that should be used for on base placement. It is important to hold the hair at a 45 degree angle forward to achieve the desired result.
