Threading is fast becoming one of the most popular methods of hair removal and dates back to ancient times. Threading is done by using pure cotton thread, which is manipulated to remove unwanted hairs from the roots and is much kinder on the skin and often less painful than other methods of hair removal. With regular threading, the hair follicles weaken, which means new hair will grow back finer and sparser. Re-growth usually takes between 2 – 4 weeks.
