Can I use Toppik Hair Building Fibers with other hair products?

Yes, but with a specific order. It's recommended to apply Toppik Hair Building Fibers after using any heat styling tools like hairdryers, straighteners, or curlers.

Styling products (except hairspray) should be applied before the fibers.

Applying gels, mousses, or similar products after the fibers might cause them to move and expose areas you meant to cover. Let styling products dry completely before using the fibers.
