While some of us are blessed with thick, luscious locks, the rest of us are not quite so lucky. If (like me) your hair is fine and lacking oomph, you’ve probably tried a fair few hair products to try and add that extra volume to your hair – but have any of those been clinically proven to increase the thickness of your hair by 20 per cent in just eight weeks? Yep, probably not. That’s where Absolute Collagen’s Complex Hair Thickening Shampoo and Conditioner Duo comes in.

The shampoo and conditioner duo has been clinically tested and proven to thicken hair and increase growth. Plus, it contains 97 per cent natural ingredients – a win in our books. The way that it works is that it uses groundbreaking collagen technology to boost thin, flat hair, while also combatting the signs of ageing hair by using its unique formula.

Soluble collagen is a key ingredient, which wraps around the hair cuticle to form a protective and nourishing layer, resulting in glossy locks, and the collagen’s amino acids also find the cortex of the hair and penetrate it, adding thickness and volume. Wheat protein and plant protein also work together to boost the body of the hair and strengthen it too. Absolute Collagen’s conditioner then works to hydrate the hair, as it contains enriching oils that will smooth and strengthen your hair even further, preventing split ends.
