We keep Perfectil Original Formula for Hair Skin and Nails on our biotin, hair & nails shelf alongside 47 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: See the latest price and availability on Amazon. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.5 out of 5 across 3,400 ratings. How that compares with the rest of the shelf is below.
We track 48 rated biotin, hair & nails products, and the middle of that pack scores 4.4 out of 5. This one is on 4.5. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.
That score rests on 3,400 ratings. The median for this shelf is 630. That's a deep enough base for the score to be stable, and it is the reason we rank on volume as well as stars.
Price-wise it falls in the bottom third of a shelf that stretches £3.99 to £29.99, with £9.99 in the middle. Cheap with a middling rating is a fair trade if the specifics suit you, and it is the usual reason to pick something at this end of the shelf.
