History of keratin treatments

Keratin treatment was invented in Brazil 20 years ago due to the demands of the large population wanting straight hair. This product contained low grade keratin but a high proportion (9-15%) of formaldehyde. Formaldehyde was the active ingredient that preserved the hair and the results were amazing with hair staying straight for 6 to 12 months. However, this product was harmful to the respiratory system and is classed as Group 1 carcinogen by World Health Organisation (WHO).

USA, UK and Israel scientist developed the technology further and developed higher quality ingredients that had acceptable results straightening hair up to 3-4 months. They were able to reduce the level of formaldehyde and increase better keratin compounds. The legal levels allowed in keratin treatments is 0.05–0.2%. The latest technology have zero formaldehyde and can still deliver results of 3-4 months.
