I had done permanent hair staightening from onyx salon.One of my friend suggested me this place.I went there just to enquire as i was confused about the reviews on hair straightening.They were so amiable and polite and i did the straighening the same day.I did on Oct 2013 and my hairs are still so smooth n straight(except the new hair growth).i dont use any other products like serum and all..I shampoo and condition once in a week.I do hot oil massage too and spa once in a month.
Thanks Onyx.
