L´Oréal Professionnel Fix Smoothing

This is a fabulous hair serum. I’ve been using this literally for about 15 years and always come back to it. 48 hour humidity control and can prevent frizz and curl post styling. Use before and or after you have styled your hair. Instantly smoothes your hair

Love this product. I am very critical about hair products because in the majority of cases, there are a lot of marketing arguments but the product does not give any convincing results. For this serum it smoothes the hair quite well and allows you to do a suitable blow dry. After obviously everything depends on the condition of your hair.
