Which product is used for temporarily straightening hair?

The product that is used for temporarily straightening hair is straightening gel. This type of gel contains specific ingredients designed to coat the hair strands, effectively smoothing and reducing frizz while providing a temporary straightening effect. When applied to damp hair and then styled with heat, straightening gel helps to achieve a sleek look that can last throughout the day.

Smoothing balms and hair serums are primarily used for controlling frizz and adding shine rather than directly straightening hair. A heat protectant is essential for safeguarding the hair when using heat styling tools but does not contribute to the straightening process itself. Therefore, straightening gel stands out as the most appropriate choice for the temporary straightening of hair.
