One posted: "That's nasty. How would you eat with those nails". While another hit out: "Unfollowing now, these post are just getting ridiculous".
However a handful pointed out the design would add an extra eerie touch to a Halloween costume.
"Omg whatttt THESE are my Halloween dream nails," gushed one.
The step-by-step video shows a manicurist starting by painting the nails with black varnish.
She then snips brunette hair hair extensions - roughly double the length of a finger - into narrow portions roughly the width of a nail bed.
The strands are then applied seemingly directly onto the wet polish. With an eye for detail, the nail artist then takes a small brush to detangle the hair extensions.
Asking for views on the design, the salon captioned the clip: "Hair on the nails - new trend - YAY NAY?".
Nail Sunny definitely thinks outside the box, considering they've done a variety of other unique nail designs in the past.
In June, the nail salon created another crazy manicure called the 'brush nails', which featured crafted combs on each finger that someone can rake through her own hair.
And in January, the salon revealed an intricate and over-the-top design in honor of Valentine's Day complete with two miniature dolls and a heart-shaped box with a sparkly wedding ring inside.
The founders of the amazing salon, which does a ton of different transformation manicures and pedicures, are sisters Eleonora and Arina Movsisyan.
They lived in Los Angeles before taking their experience to Moscow to open the salon.
