• Salerm 21 is more than a leave-in conditioner and a moisturizing mask. • Its silk protein-based formula penetrates to the core of the hair, caring for and revitalizing it from the first use. • It provides shine and life to the hair, protecting it from external agents such as sun, chlorine, salt, or heat. • Use as a mask: for very damaged hair, apply between 5 and 10 ml of Salerm 21 and leave it on for 5 minutes. Rinse and comb. • Use as a protector: to prevent hair breakage from tangles, apply a small amount of Salerm 21 to dry hair and comb as usual. • Use as a moisturizer: after washing, apply a hazelnut-sized amount of Salerm 21 distributed throughout the hair, focusing on ends and damaged areas. No need to rinse. Comb as usual. • Product dimensions: 5 cm wide, 10 cm high, 10 cm long. Total weight: 0.3 kg.
