We use the CHI Keratin Enviro Smoothing Treatment is Ammonia and Formaldehyde FREE and takes approximately 2.5 hours to apply and then blow dry and iron into the hair. This treatment takes up to 4 months to fade out and is great for getting rid of up to 95% of frizz, whilst retaining the natural curl without regrowth. You will find that blow drying the hair will take half the time since you don’t have to deal with the frizz factor. The Keratin gives increased manageability, shine and intense moisture to the hair and is great for damaged hair types. This service can really help if you are going on holidays and want to leave the hairdryer at home.
