Amal Clooney's hair is some of the glossiest in Hollywood, and George Clooney's wife isn't afraid to embrace the volume and go for a rich girl, bouncy blow-dry.

And it's not just the shine on Amal's hair. It's the thickness too. At 48-years-old, her luscious locks are ones I covet and whether she's beside husband George at a red carpet event like the Venice Film Festival or doing her day job as a human rights lawyer, you best be sure she is going to work that hair of hers. It looks expensive, and I want it.

  • We've discovered Amal Clooney is a fan of Garnier Fructis Hair Filler Serum.
  • The $10 hair product strengthens hair, and can be used post styling. 
  • Reviewers confirmed results, calling the product "amazing."

As someone in their 40s, I needed to know more as to how Amal's hair is so thick, glossy and full. And it's a humble hair repair serum you can pick up on Amazon for under $10. 

According to reports, Amal's hair stylist Dimitri used the Garnier Fructis Hair Filler Serum for a lavish event in Venice last year, where he created an "Italian Sophia Loren blow-out." The product, priced at $9.99, helps to strengthen hair and smooths it, while repairing it at the same time too. Ingredients like citric acid in the sulfate-formula act as an anti-aging agent for the hair, great for weak or damaged hair and penetrates seven layers deep.

It should be used as the final step in your haircare routine, post shampoo and condition and applied to dry, clean hair. We love a multi-functional product that not only helps our hair on the outside, but on the inside too. And with all of the red carpet events Amal attends, her hair must be put through its paces with heat treatments and styling products so this could be a nifty serum to keep in your haircare repertoire, especially during the holiday season when we tend to over-process our hair a little more.

Garnier Fructis Hair Filler Serum - shopper reviews

I've used plenty of strengthening and thickening products but never this, so I've turned to the Amazon reviews section to understand it further.

Fuller, thicker and shinier hair are just some of the benefits users of this product reported. Most used it as part of the Garnier Fructis four-step program, with "amazing" results being reported as "immediate." 

I think if you're someone who needs a hair lift, be it thicker or stronger, this is worth a shot; it's not too expensive that it'll break the bank and just might help to thicken your hair. I'd definitely recommend trying the whole routine, as it seems they work in tandem and each product helps the other to work harder and better.
