This patient has classic female patterned balding with hair loss behind the frontal 1/2 inch. The thinning is worse in the frontal area and is more manageable in the top and back, but still thin and see-through. I have given this patient DermMatch, which is a cosmetic powder that colors the scalp and sticks to hairs to make them thicker. The contrast between hair and scalp is lessened with this product and when combined with good styling, products like this (see also, Toppik) can work to make the transparency of the hair less so. The photos below show how big of a difference a topical camouflage can make.
