Cut: Physical and chemical stress on the follicles is bad news for those with thinning hair. So stay away from any style that requires accessories or a lot of products to maintain. Lengthwise, short to mid is best.
Colour: Lighter colours are a definite no as they will only draw attention to your hair thinning. Darker colours, by contrast, will make your hair appear more voluminous. Jet black and deep browns are the way to go.
