Here's why:
* Crackle Polish Mechanism: Crackle nail polish works because the formula is designed to shrink rapidly as it dries. This shrinkage causes the top coat to split and crack, revealing the base color underneath. This effect is usually achieved with specific ingredients that create uneven drying and contraction, like volatile solvents or specific types of polymers.
* Witch Hazel Properties: Witch hazel is primarily known as an astringent and toner. It contains alcohol and tannins, which can help to tighten skin and reduce inflammation. It's used for things like acne treatment, reducing swelling, and soothing irritated skin.
* Lack of Shrinkage/Contraction: Witch hazel doesn't inherently possess the properties that would cause a nail polish formula to rapidly shrink and crack in the same way as a crackle polish. It might influence the drying time or texture of a polish to a small degree, but it wouldn't create the dramatic cracking effect.
In summary, you'd need specific ingredients designed to cause that shrinking and cracking effect, which witch hazel alone does not provide. You'd be better off researching and acquiring ingredients known for their crackling properties, such as specialty solvents or polymers used in nail polish formulations.
