The treatment seems to have worked brilliantly, (I've yet to wash it). The staff gave every impression of doing a really thorough job. I booked Jessica specifically because of her reviews but only got her for half of my session, then I swapped to a very friendly lady but as she didn't speak any English it was hard to communicate and not possible to ask questions I had. Thankfully I'd asked about shampoo for post treatment at the beginning but overall it would be fair to say the price of this treatment is the great advantage; it's not s place for luxury or smooth customer service. Excellent coffee though.
