What is hair thickening shampoo? Your 101 guide

Do hair thickening products really work?
Even the best hair thickening shampoo for men can’t alter the chemical structure of your hair and actually make it thicker – but it can give you fuller, thicker looking locks with specialist formulas that help pump up the appearance of thin, flat hair. Just like regular shampoos, thickening shampoos also cleanse your hair, washing away grease and dirt that can weigh it down and leave it looking flat and lifeless.

So, how does hair thickening shampoo work?
By coating individual strands of hair with ingredients like proteins and calcium, thickening shampoos and conditioners can make your hair shafts look thicker. They also moisturize the follicles. One of the largest components of hair is water, so thickening shampoos add extra moisture to those follicles and make them swell, giving you a thicker looking head of hair.

What’s the best formula for thin + flat hair?
We think two of the best hair thickening products for men with thin, flat hair are our RE+AL Bio-Mimetic Revitalize Coco Fatty Acid + Vegan Collagen Shampoo and Conditioner. Infused with vegan collagen for hair, and vegan keratin equivalent to your hair’s protein, this duo gives hair volume by visibly thickening its appearance and making it look 3x fuller.* Our bio-mimetic formulas copy your hair’s natural protective process with 100% nature-derived active oils.** They’re also 100% biodegradable*** with 0% silicones or parabens.

If you want a powerful formula that can do both, lather up with our Dove Men+Care Thick + Strong Fortifying 2-in-1 Shampoo + Conditioner instead. Infused with caffeine and calcium, it helps strengthen hair root-to-tip and makes it appear thicker and fuller. It also leaves you feeling fresh with a rich patchouli and sandalwood scent.
