The keratin treatment comes from the land of carnival and Caipirinhas; Brazil. The treatment is therefore also called Brazilian blow-dry. Here women and their hairdressers have known for some time that fluffy or frizzy hair is not done. They therefore embrace this beauty trend en masse and thereby save themselves a lot of irritation and bad hair days. The treatment is very popular with celebrities and it is not for nothing. The semi-permanent treatment makes your hair smooth, soft and lint-free for up to 5 months. Moreover, you save yourself a lot of time and effort because you no longer have to work with smoothing shampoo, conditioner, hair straightener or hair dryer every day.
