A spray-on thermal protector is applied prior to thermal services to prevent damage from what?

A spray-on thermal protector is specifically designed to shield hair from the damaging effects of heat applied during thermal styling services, such as blow drying, flat ironing, or curling. When heat is applied to hair, it can lead to moisture loss, resulting in dryness, brittleness, and potential damage.

Using a thermal protector forms a barrier around the hair strands, significantly reducing the risk of heat damage by absorbing and dissipating some of the heat before it penetrates the hair cuticle. This helps in maintaining the hair’s integrity while allowing the stylist to achieve desired results with styling tools.

In contrast, options like chemical treatments, coloring, and brushing do not inherently involve the direct application of heat that would necessitate a thermal protector. Therefore, a spray-on thermal protector is primarily associated with protecting hair from the high temperatures encountered during blow drying and similar thermal styling methods.
