Do you have to use heat after or can you just use it on dry hair normally

Hi Kaitlyn! Thank you for your interest in Elvive Dream Lengths Frizz Killer Serum. This is the recommendation for use. Usage: After using Dream Lengths shampoo and conditioner use 1-2 pumps on damp hair before blow-drying. Once dry, flat iron. To tame frizz and static, apply a small amount on dry hair.
