Instead, you may want to add vitamin D (about $15) to your shopping cart. A vitamin D deficiency can exacerbate hair thinning and make it almost impossible for any over-the-counter product to reverse hair loss, says Dhaval Bhanusali, a dermatologist in New York City, who recommends taking 5,000 international units of D3 a day (and it’s generally beneficial for bone health in women over 40). “There’s also a link between low iron and zinc levels and temporary hair shedding, called [telogen] effluvium,” says Rogers.


Thanks for the article with great info. I’ve been taking minoxidil 5% for the last 2 years. I’ve tried a generic minoxidil brand and also Kirkland to no effect. I’ve been hoping it’s maybe slowed the hair loss process. The hair around my crown just keeps getting thinner. Do you think changing to another “better quality” brand like Lipogaine or Rogaine could work? Or does it appear that any minoxidil brand is not going to work?
