I recently bought a pair of thinning scissors for myself, and my friend has advised me to use it inwards, like thinning the hair down the strip, however, I think, I sort of thinned my hair slightly up the edges. It is not really looking bad, but I am worried, as it was for the first time, and I am not sure whether I goofed up or what! Can somebody please suggest if there is any way other than the parlor to set my hair right? Thanks.
