I went to Mina Dew'ill in Cochrane Street to get my hair straightened last Saturday, after spending 5 hours, my hair was still wavy. The stylist Samson asked some junior stylist who had not experience to do my hair. He then tried to then convince me that my hair was straight. He then asked to come on Monday after work and again after spending 3 hours retouching - it was not straight...such a waste of money and time. I dont recommend Mina De'will for any hair treatments.
