Bluebonnet Biotin 1000 mcg B Vitamin That Helps Make Keratin, Vegan, 90 Vegetable Caps

After experiencing hair thinning years ago which began during a time of female hormonal imbalances, I began taking this Biotin twice a day. Several months later, there is a noticeable difference in my hair thickness and length. At one time I ran out of Bluebonnet and got a drugstore brand; it was not as effective. 1000 mcg. capsules are plenty; taking a higher dosage does not result in faster hair growth, since this is a water soluble vitamin and any excess is just excreted from the body.
