Men and women use different razors, but there is no difference between men’s and women’s razors. There are differences between brand names. Gillette issued a press release in which it stated that the blades used in its gendered products both use the same 'blade technology'.
Women’s razors are generally more expensive than men’s, but cost to
manufacture different shapes are negligible. The razors for women
are usually larger to cut more hair. The heads of men’s razors are
designed to facilitate more accurate facial grooming with smaller
heads around the blades, as well as having the blades more tightly
packed. This serves to better cut thicker hair commonly found on
men’s faces vs. women’s legs, and to cut hair closer to the skin.
The blades of men’s razors are often put at more of an oblique angle
than women’s razors, along with a different contour of handle. The
difference in angle and handle shape allows women to see better what
they are shaving when looking down at their legs vs. men looking
straight into a mirror.
Shaving creams are also identical, except for aroma, because women
prefer different fragrances than men.
So, the price for women is much higher, because of perception and
because women are more inclined to pay more - for any number of
non-tangible reasons. Men see shaving as a chore and women tend to
think of it as beauty enhancing. Save some money and use the
less expensive alternative razors, creams, and gels, just do not
share the same razor.
