I got the last appointment of the day - so no rushing! My cut and blow dry took 1.5 hours, the longest haircut I've ever had - nice to not be rushed, and full attention to detail!
I was able to get an appointment the same week easily and the haircut was great.
It is worth noting that some of the available slots on Treatwell don't exist at the salon (I don't think they do appointments on the half hour, but these show up as booking options on Treatwell). This may be a flaw in the Treatwell platform rather than anything to do with the salon, though.
Had a haircut and blow dry from Louisa. Great experience, she listened to what I wanted and talked me through everything she was doing. Definitely going back.
