This condition leads to temporary hair loss and other medical conditions especially in women. Safe dosage of vitamin A is 4 000 to 5 000 IU per day.

Zinc can be toxic when taken in excess of 60 milligrams daily. Stick closer to the recommended daily dose of 11 milligrams but higher doses below 60 mg can increase hair growth.
hormones

As a result people who take contraceptives or HRT drugs experience hair loss. Normally the body adjusts to the hormones after three to four months and hair loss decreases.

Fortunately some companies voluntarily follow the standards that FDA establishes medicine.
