In brief: No

There are no dietary supplements to either increase or decrease hair growth (or loss), no matter what's promised by manufacturer's advertising.
Of course if slow hair growth is due to some nutritional deficiency, then correcting said deficiency will help but not as a general rule for whole population. Also need to consider thyroid disease, infection & autoimmune disorders so see your FamilyDoc.
