I am also agree with Pomfry, what I know is hair loss in women
produces scattered thinning over the top of the scalp rather than a
bald spot. Minor patterned hair loss occurs in over 55 per cent of
women as they age, but only about 20 per cent of women develop
moderate or severe hair loss. But for pregnant woman my general
advice is keep it simple, less is more with respect to personal
care product use. A number of treatments are available for female
pattern hair loss, including topical minoxidil lotion that are not
recommended for pregnant woman and which have antiandrogen
properties, these are available on prescription and require a
doctor’s supervision.
