providing the first modified video segment for presentation at the client device, the first modified video segment including the first visual indicia related to the first operation of the application of artificial lash extensions, wherein the first modified video segment provides feedback directed at the application of artificial lash extensions to the subject.

2 . The method of claim 1 , further comprising:

determining whether a second video segment of the video stream received from the client device satisfies a first condition related to the first operation of the application of artificial lash extensions.

3 . The method of claim 2 , further comprising:

responsive to determining that the second video segment does not satisfy the first condition, modifying the second video segment to include second visual indicia identifying a corrective action related to the first operation of the application of artificial lash extensions; and

providing the second modified video segment having the second visual indicia for presentation at the client device.

4 . The method of claim 2 , further comprising:

responsive to determining that the second video segment does satisfy the first condition, modifying the second video segment to include third visual indicia identifying an affirmation indicia related to the first operation of the application of artificial lash extensions; and

providing the second modified video segment having the third visual indicia for presentation at the client device.

5 . The method of claim 2 , wherein determining whether the second video segment of the video stream received from the client device satisfies the first condition related to the first operation of the application of artificial lash extensions, comprises:

receiving, from the client device, the second video segment of the video stream; and

performing a computer vision operation on the second video segment to detect a visual representation of a position change of an artificial lash extension of the artificial lash extensions with respect to an underside of natural eyelashes of the subject.

6 . The method of claim 5 , wherein performing the computer vision operation on the second video segment to detect the visual representation of the position change of the artificial lash extension of the artificial lash extensions with respect to the underside of natural eyelashes of the subject, comprises:

determining whether the position change of the artificial lash extension qualifies as a correct positioning of the artificial lash extension for the first operation of the application of artificial lash extensions.

7 . The method of claim 5 , wherein to detect the visual representation of the position change of the artificial lash extension of the artificial lash extensions with respect to the underside of natural eyelashes of the subject, the computer vision operation is to detect at least a position change of an applicator of the artificial lash extension.

8 . The method of claim 1 , wherein the first operation of the application of artificial lash extensions comprises an application of adhesive at an underside of natural eyelashes of the subject.

9 . The method of claim 1 , further comprising:

modifying a third video segment of the video stream to include fourth visual indicium related to a second operation of the plurality of operations, the second operation comprising arranging the artificial lash extensions at an underside of natural eyelashes of the subject; and

providing the third modified video segment for presentation at the client device.

10 . A system comprising:

a memory device; and

a processing device coupled to the memory device, the processing device to perform operations comprising:

receiving, from a client device, a first video segment of a video stream;

generating, using the first video segment, a three-dimensional (3D) model of a human face of a subject;

modifying the first video segment to include i) a first overlay of the 3D model identifying one or more landmarks and ii) first visual indicia positioned in the first video segment based on the one or more landmarks of the 3D model and related to a first operation of a plurality of operations of an application of artificial lash extensions, wherein the artificial lash extensions are physical objects; and

providing the first modified video segment for presentation at the client device, the first modified video segment including the first visual indicia related to the first operation of the application of artificial lash extensions, wherein the first modified video segment provides feedback directed at the application of artificial lash extensions to the subject.

11 . The system of claim 10 , the processing device further to perform the operations comprising:

determining whether a second video segment of the video stream received from the client device satisfies a first condition related to the first operation of the application of artificial lash extensions.

12 . The system of claim 11 , the processing device further to perform the operations comprising:

responsive to determining that the second video segment does not satisfy the first condition, modifying the second video segment to include second visual indicia identifying a corrective action related to the first operation of the application of artificial lash extensions; and

providing the second modified video segment having the second visual indicia for presentation at the client device.

13 . The system of claim 11 , the processing device further to perform the operations comprising:

responsive to determining that the second video segment does satisfy the first condition, modifying the second video segment to include third visual indicia identifying an affirmation indicia related to the first operation of the application of artificial lash extensions; and

providing the second modified video segment having the third visual indicia for presentation at the client device.

14 . The system of claim 11 , wherein determining whether the second video segment of the video stream received from the client device satisfies the first condition related to the first operation of the application of artificial lash extensions, comprises:

receiving, from the client device, the second video segment of the video stream; and

performing a computer vision operation on the second video segment to detect a visual representation of a position change of an artificial lash extension of the artificial lash extensions with respect to an underside of natural eyelashes of the subject.

15 . A non-transitory computer-readable medium comprising instructions that, responsive to execution by a processing device, cause the processing device to perform operations comprising:

receiving, from a client device, a first video segment of a video stream;

generating, using the first video segment, a three-dimensional (3D) model of a human face of a subject;

modifying the first video segment to include i) a first overlay of the 3D model identifying one or more landmarks and ii) first visual indicia positioned in the first video segment based on the one or more landmarks of the 3D model and related to a first operation of a plurality of operations of an application of artificial lash extensions, wherein the artificial lash extensions are physical objects; and

providing the first modified video segment for presentation at the client device, the first modified video segment including the first visual indicia related to the first operation of the application of artificial lash extensions, wherein the first modified video segment provides feedback directed at the application of artificial lash extensions to the subject.

16 . The non-transitory computer-readable medium of claim 15 , the operations further comprising determining whether a second video segment of the video stream received from the client device satisfies a first condition related to the first operation of the application of artificial lash extensions.

17 . The non-transitory computer-readable medium of claim 16 , the operations further comprising:
