The objectives of both treatments are similar: to eliminate frizz, smoothen your locks, enhance shine and reduce blow dry time. The fact is other than the brand and the ingredients they use to meet the similar objectives, the difference between the two is not much just like Coke and Pepsi. Both treatments may or may not contain formaldehyde and other chemicals. It is well acknowledged that you will get more of a smoothing and deep-conditioning effect with a keratin treatment. In Hera salons, we use Goldwell Kerasilk, which is the latest generation of hair smoothing systems that replaced harmful formaldehyde with safe glyoxcylic acid derivatives to create new keratin bonds. These fresh bonds will help to stabilise your hair shape whilst also forming straighter bonds on your hair shaft.
