Unfortunately nutritional supplements are hit and miss. While the risks of side effects go down which is attractive, clinical data is sparse. In most cases the individual has to conduct their own experimentation. At 6 months a pop for a fair trial, this is a time consuming process. Time is a very limited commodity especially in the hair loss game. As we know, it is easier to do preventative maintenance than reverse hair loss. Nevertheless, natural DHT inhibitors like saw palmetto and nettle have worked to prevent hair loss in some users.
Dupilumab is FDA approved for treating eczema aka atopic dermatitis and sold under the brand name Dupixent. As the story goes, a patient with alopecia totalis (a form of areata which leaves a person’s head completely bald) was being treated for eczema by the drug Dupixent. After 6 weeks the patient first began to notice progress in terms of hair growth and at 7 months she had noticeable pigmented hair growth on her scalp. Notably, the patient stopped taking the dupilumab for a period of time and noticed her growth subsided; when she began taking the drug again the hair improved once more. This provides another useful therapy option for patients seeking treatment for AA. One would imagine a topical version would be worthwhile to investigate.
