will it cause crunchiness or stickiness?

No, this lightweight, non-sticky formula provides flexible lift + hold without leaving hair sticky, crunchy, or weighed down. For best results, apply 4-6 inches away from hair and scalp.

Reviews Summary

Customers say this volumizing spray gives their fine, thin hair noticeable lift and body without weighing it down or making it feel sticky. Many report achieving lasting volume that holds through the day and even into the next. Users appreciate that it works on both wet and dry hair, with most finding it particularly effective when applied to damp hair before blow-drying. The lightweight formula leaves hair feeling soft and touchable rather than stiff or crunchy. Many reviews mention the pleasant fragrance. While most users with fine hair see significant results, some with thicker or heavily-treated hair find the effects more subtle. A few customers note concerns about the spray bottle leaking during shipping.
