Medications that are prescribed to thicken thinning hair in women include minoxidil, finasteride, spironolocatone and latisse, states WebMD. These are useful for countering inherited hair loss. If hair loss is due to an immune system attack on hair follicles, corticosteroid scalp injections, creams and ointments are prescribed.
Minoxidil is an FDA-approved hair loss medication for women that prevents hairs from becoming thinner and helps to regrow hair on the top of the head, says WebMD. This medication is considered the safest for hair loss treatment for women, is available without prescription and is rubbed into or sprayed on the scalp two times a day.
Two hair loss drugs that are available strictly by prescription are finasteride and spironolactone, reports WebMD. Finasteride is an oral medication that is taken once a day as a pill. However, since this drug affects the hormone testosterone, it is not prescribed for pregnant women as there is risk of birth defects in male children. Spironolactone also has similar side effects and additionally increases blood potassium levels. Most doctors prescribe these medications to women who are past menopause or when minoxidil proves ineffective.
Sometimes doctors also prescribe latisse, which is FDA-approved as an eyelash enhancer, states WebMD. If hair loss occurs in women due to an immune system attack on the hair follicles, corticosteroids are prescribed as a scalp injection, ointment or cream independently or with other hair loss medications such as minoxidil.
