★ ( Note: The hair length in the tutorial is not the actual length but measured from the image's hair length.)

(1) Firstly, to create a 'horizontal bob' :

① Use a 'horizontal blocking' technique.

② Cut all sections of the hair on the 'nape' to the same length of 71.83mm. ③ Cut in a vertical direction on the scalp surface.

(2) The cut line formed by hair cut to the same length in 'Nape Blocking' can be measured almost horizontally.

① However, due to 'the nature and positioning of the hair, as well as the visual factors represented by the actual cut shape', the shape of the 'horizontal bob' cannot be precisely achieved.

​

② 'The nature of the hair' involves factors such as 'ⓐ thickness and weight of the hair', 'ⓑ factors related to wet and dry states of the hair',

'ⓒ factors related to styling with a dryer', which can become factors that prevent the accurate creation of the 'horizontal bob'.

​

    ③ 'The positioning of the hair' can also be a factor as the position of             the cut hair towards the ground isn't always the same as the                     direction of gravity, and it's constantly in motion.

    

③ 'The positioning of the hair' can also be a factor as the position of the cut hair towards the ground isn't always the same as the direction of gravity, and it's constantly in motion.

​

④ 'The actual visual factors' indicate that the 'horizontal shape' depicted by the same length cut tends to be positioned slightly higher than the actual horizontal line.

​

⑤ Due to these reasons, when cutting hair to the same length, it becomes impossible to create an exact 'horizontal bob'.

​

⑥ Therefore, the method to create the 'actual horizontal form' involves progressively cutting each section slightly longer from the symmetry axis.

​

(★Note: ① This is the height difference between the three hair positions and the hair position on the symmetry axis. ② However, this is the height difference measured after removing all the factors that interfere with creating a 'horizontal bob'.)

(3) At both ends of the 'Nape Blocking' section, there exists a 'hairless space.'

① Hair within this 'hairless space' refracts closer to the scalp due to its lower density.

② Cutting hair to an even length results in the inability to create the form of a 'horizontal bob' due to the 'hairless space.'

(★ Note that the scalp surface in 'Nape Blocking' has irregular 'curvature.' This irregular curvature has a subtle impact on creating the form of the 'horizontal bob.)

​​

(4) Ultimately, to create an accurate 'horizontal bob':

If there is an error in the optimal 'backward movement distance' for creating the perfect 'horizontal bob,' it could transition beyond the 'horizontal form' into an 'A-line shape'!

Hence, skilled experience is necessary to determine the most suitable 'backward movement distance.
