my hair is long and silky and i really take good care of it.i shampoo it and oil it with the best products allowing no dust to enter my hair follicles.they had been cut in a laser cut earlier but now they have grown again and fall evenly on my shoulders,so now i am thinking of trying out a new hairstyle.then my friend told me about Straight Across Bangs would make me look really different.are there any Straight Across Bangs for oval face?and how long does the Straight Across Bangs look stay ?also do i need to get it cut at regular intervals to maintain the length?
