Keratin treatments Sydney

Keratin treatments are a wonderful way to tame hard-to-manage hair or just to reduce the time to get ready. Over the years there have been many different brands that have promised the world but hardly delivered. Also there have been some changes in the ingredients used to make it legal for use in Australia. The wide range of keratin treatment options can make it confusing to decide which system is the best for your hair. In this article we break down what is achievable by the different systems based on the desired results.

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 classified as Group 1 carcinogen by World Health Organisation (WHO).

Scientists from the USA, UK and Israel 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.
