My stylist was very friendly, professional and efficient - it normally takes ages to do my highlights but I was out the door before the end of the appointment time!
I get the Kerastraight done every 3-4 months and it really smooths my hair making a noticeable difference! The only criticism would be that it's rather expensive, especially since it wears off within 3 months so needs to be continuously topped up, adding up to almost £300 for 3 treatments a year.
