I used to see big clumps of hair in the shower

Verified Purchase

By Jemel, C

I love this shampoo. I used to see big clumps of hair in the shower drain everytime after showering. Since using this those hair strands in the drain have practically gone away and my hair looks much better as a result.

Why we made the Hairguard Shampoo:

The plant-based way to thicker, healthier hair. Support healthy hair growth the natural way with proven, ultra high quality active ingredients that work with your body.

The Hairguard Caffeine Shampoo contains plant-based, active ingredients which gently clean the scalp without stripping away naturally protective oils. 

Ultra high-quality active ingredients support thicker, healthier hair growth via natural plant extracts that have been proven to improve hair growth outcomes in studies.

The Hairguard Caffeine Shampoo turns every hair wash into a chance for thicker, healthier hair:

  • Supports thicker, healthier hair

  • Gently cleans without irritating the scalp

  • Leaves hair feeling thicker and fuller

  • Optimises scalp pH

  • Plant-based, natural extracts

Healthy scalp = healthy hair. Now you can gently clean the scalp and support healthier hair in every wash. Take a look at the difference in scalp and hair health after 6 months of using the Hairguard Caffeine Shampoo:

What proven ingredients make this shampoo so effective?


Oleuropein is scientifically proven to support healthy hair, beating alternatives in all 4 success criteria. It penetrates deeply into the scalp giving maximum benefit without a residue.


Caffeine helps promote blood flow and combat DHT, making it an ideal environment for new hair follicles to be as healthy as possible.


Taurine has been shown to help slow down fibrosis (the process that reduces blood flow.) It's also a proven anti-inflammatory. Lastly, it's shown to protect the hair follicles from stress-induced hair loss.

Coconut oil

Coconut oil has been proven to reduce protein loss from the hair, so your hair stays thicker and stronger. This is especially important in areas of hard water. Helps protect and soothe the scalp without being greasy or messy.

Apple cider vinegar

Apple cider vinegar gently cleans, removing dirt, grease and plaque, but without stripping away protective oils. It also helps maintain optimal skin pH and doesn't kill beneficial bacteria like most shampoos.

Peppermint extract

Peppermint essential oil is a vasodillator, which means it can increase blood to the hair follicles, keeping the hair itself as strong as possible and much less likely to fall out.

Are you okay with losing all your hair in 15 years' time?

Thinning hair progresses in a well-known pattern called the Norwood Scale. Although the rate of hair loss varies between people, the typical time-frame for someone to lose their hair is around 15 years as you can see in the diagram. 

Whatever stage you are at now, are you going to be happy in 2 or 3 years time when you reach the next stage if you do nothing? 

If nothing changes then your hair will get worse. But if you decide to do something now then in 6 months' time you can have more, thicker, healthier and stronger hair than you have today.

Life's better with thick, healthy hair.

You know those shampoo adverts with all that lovely foam? Turns out that foam comes from a chemical called SLS and it's actually really bad for our hair. It's the same chemical used in car washes.

Most shampoo makers add SLS to their formula to make it look and feel foamy. Looks nice, feels nice but actually hurts the hair follicles.

Our formula contains only ingredients that gently clean or help boost hair growth. Life's better with thick, healthy hair and we're willing to give up the foamy feeling to get there.

How long before I start seeing results?

It varies for everyone, but after 3 - 4 months you should be able to accurately see how well it is working for you.
