Salerm Cosmetics expands its Salerm 21 family with the launch of Salerm 21 Thermal Protector, an innovative dry thermo-protective spray that combines nutrition, repair, and advanced thermal defense, designed to respond to one of the main concerns of today's consumer: the damage caused by the daily use of thermal tools.

Under the claim “Your best-kept treasure”, the campaign stars the renowned actress María Castro, who embodies the care, protection and value of hair as a personal asset that deserves to be preserved.

A real response to an everyday problem

In a context in which up to 80% of hair damage is related to the use of thermal tools, Salerm Cosmetics launches a solution that goes beyond the traditional concept of thermal protector. Salerm 21 Thermal Protector has been developed to offer a real protection tested at high temperatures, responding to the needs of professional and domestic use, where straighteners and dryers reach levels superior to what many products on the market are capable of withstanding.

Nutrition and advanced thermal defense in a single gesture

The new launch comes in a format dry spray without rinsing, with a light texture that does not add weight or residue, and that allows working the hair with total freedom.

Its advanced formula integrates the 21 benefits of the Salerm 21 family such as:

  • Silk protein (Silk Protein), which repairs and strengthens the cuticle.
     
  • Encapsulated Vitamins E and B5, which nourish and protect the hair fiber.
     
  • A system of thermal stability up to 300ºC, which guarantees effective protection against extreme heat.

In addition, its technology allows a homogeneous heat distribution, avoiding thermal peaks that generate micro-fractures and deterioration of the hair fiber.

Demonstrated efficacy and visible results

Salerm 21 Thermal Protector not only protects, but acts as a complete treatment during the thermal process:

  • Reduces significantly the structural damage caused by heat
  • Increases the resistance of damaged hair
  • Seals the cuticle, improving softness and shine
  • Controls frizz even in humid environments
  • Maintains a light, natural and non-weighing down finish

Instrumental tests have shown that the product increases hair resistance to breakage and reduces hair mass loss, even after intensive exposure to thermal tools.

The new must-have of Salerm 21

With this launch, Salerm Cosmetics strengthens the positioning of Salerm 21 as one of the most iconic families in professional hair care, maintaining efficacy and evolving towards new needs of the current consumer and salon.

Salerm 21 Thermal Protector becomes an essential step within the care ritual, especially in sensitized, treated or frequently heat-exposed hair, providing an effective solution that combines protection, treatment and professional finish in a single gesture.
