Overview

OGX Biotin and Collagen Volumising Hair Shampoo, Thick is no longer listed on Amazon. We have kept this page because it was part of our hair care shelf, and the comparison below still shows where it stood while it was on sale. Here is how the maker describes it: OGX Thick and Full plus Biotin and Collagen volumising Shampoo with a nutrient-infused formula help give your hair 72plus hours of volume and body and healthy hair in just one wash. Our improved formula protects hair against damage by strengthening your strands by protecting hair from excessive loss of lipids and proteins vs non conditioning shampoo. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.4 out of 5 across 24,687 ratings. How that compares with the rest of the shelf is below.

How it compares on the hair care shelf

We track 50 rated hair care products, and the middle of that pack scores 4.5 out of 5. This one is on 4.4. That sits mid-table. Ratings this close together don't decide anything on their own, so weigh pack size, price per unit and the specifics below instead.

24,687 people rated it, where the shelf median is 4,347. With that many opinions behind it the score won't move much, and it is difficult to manipulate. That is exactly why volume carries weight in our ranking.

The shelf runs from £1.98 to £56.00 and the midpoint is about £7.13. On price, this one is in the bottom third. 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.
