Complicated problem, multiple solutions
Given the many reasons for hair loss, multiple solutions are needed, the dermatologists note.
Dr. Mostaghimi said that he’s still a bit skeptical that supplements work as consistently as described or as well as described, given that he and his coauthors were unable to find any negative studies. In talking with patients who are taking supplements, he said that his first aim is to make sure they are safe. At least the supplements in the review have been studied for safety, he added.
He will encourage replacement of vitamin D or zinc or other vitamins or minerals if patients are deficient but said that he does not “actively encourage supplementation.”
Dr. Simmons-O’Brien said that, when evaluating patients with hair loss, she orders lab tests to determine whether the patient has anemia or a thyroid issue or deficiencies in vitamins or minerals or other nutritional deficiencies, asks about diet and styling practices, and takes a scalp biopsy. It is not uncommon to recommend supplementation on the basis of those findings, she added.
“As a hair-loss specialist, my job is to treat the patient at their level, in their framework, in their comfort zone,” said Dr. Goldberg. Some patients don’t want to take medications for hair loss, so she might recommend supplements in those cases but tells patients that they aren’t well studied.
She added that it can be hard to tell whether a supplement is working, particularly if it has multiple ingredients.
Dr. Mostaghimi reported consulting fees from Pfizer, Concert, Lilly, Hims and Hers, Equillium, AbbVie, Digital Diagnostics, and Bioniz and grants from Pfizer, all outside the submitted work. In addition, Dr. Mostaghimi disclosed that he is an associate editor of JAMA Dermatology but was not involved in any of the decisions regarding the review of the manuscript or its acceptance. No other disclosures were reported by the other study authors. Dr. Goldberg reported no disclosures. Dr. Simmons-O›Brien is a medical consultant for Isdin, but not for hair products.
