I've had it done at Hair Highness Salon in Jumeirah... the treatment itself was good and if I remember correctly I paid around 900 for it (I have just below shoulder length hair)... I felt my hair was back to its wavy frizzy state around 4 months after treatment in spite of only using the shampoo and conditioner recommended by them... I guess it's subject to how often you wash ur hair (I was mine daily) and also if u swim etc as the applied solution just washes off your hair over time...
