Bio straightening is an effective and long-term method for straightening your hair, usually done at a hairdressing salon or a beauty parlour with special products that can alter the structure of the hair, although the hair remains glossy and healthy. These products are not as aggressive as the products used during chemical straightening, as they are based on natural amino acids (improved by reducing the acidity). This method is suitable if you have a sensitive and delicate scalp and don’t want to use chemical straightening. The negative effect on your hair is going to be minimal. 

You cannot do this procedure at home, as it is vital to accurately measure the amount of the ingredients needed for your type of hair. The procedure lasts 2 – 5 hours. The effect (perfectly straight hair) lasts up to 6 months.
