How do I know the Max Blocker will work?

Everyone’s hair is different and will respond in different ways to different stimulants. Hairguard has been developing products for over 5 years and we have an incredibly high repeat purchase rate for the simple reason that users find it does protect against hair loss whilst significantly improving strength, density, thickness and coverage. 

At the same time we also know that for whatever reason a small minority of people don't get visible results. That's why we protect your purchase with our 180 day guarantee so you can try for 180 days totally risk free.

How does the Max Blocker work?

The Max Blocker's ingredients are handpicked based on the latest breakthroughs in hair loss science and our understanding of the growth enhancing benefits of rare plant extracts and derivitives and their ability to inhibit DHT. 

After assessing how the most potent ingredients found in Mother Nature support healthy hair growth, Hairguard’s formulation experts chose the 8 most effective DHT blocking plant extracts. All 8 are combined in this one bottle:

Is the Max Blocker safe?

The Max Blocker is formulated from ONLY the highest quality select plant derivatives. So, it contains none of the artificial additives, and harsh chemicals used in pharmaceutical treatments. 

What’s more, the ingredients used to make the Max Blocker have been sourced from premium grade suppliers worldwide. Every ingredient is also put through extensive quality testing for purity and safety before it’s allowed for use in our formulations. 

So, the Max Blocker has been shown to be safe. However, it is designed for healthy adults over the age of 18. And it’s always suggested to speak with your doctor before beginning any new hair care routine.

Can I use with other hair loss treatments?

One of the benefits of the Max Blocker is that it can be used powerfully in conjunction with other hair loss treatments such as scalp massages, dermarolling or supplementation. In fact we encourage it to get the absolute quickest results. 

That being said, you'll also find it works great just by itself. For those worried about hair loss it's the ultimate addition to your hair care regimen.

How fast does it work?

How quickly the Max Blocker gets you visible results depends on a range of factors. This includes your existing rate of hair loss, current hair density and a number of other factors. Typically people start to see positive results after 1-2 months but for some people this might take longer. 

It's a good idea to commit to at least 3 months use, as hair growth and reactivating resting hair follicles can take a really long time. If no improvement is experienced in this time, contact our customer support for a refund.

Is the Max Blocker good value for money?

The Max Blocker may seem more expensive than your average supplement. But it works out at a fraction of the cost of buying each ingredient individually and making it yourself. 

In addition, we only use the highest quality extracts from the best suppliers. Can you find these sort of plant extracts elsewhere? Yes. But typically unless you do your research you'll be finding cheap Chinese suppliers that neither care about potency, quality nor extraction method. For our formula to work with maximum affect we need to ensure that all ingredients are grown, stored, extracted and manufactured correctly.

What if it doesn’t work? Can I get my money back?

If that’s the unfortunate case, hit us up for a refund! 

We just ask that you try it for at least two months before requesting a refund and tell us about your experience. 

The remaining product will need to be returned for a refund, but we’ve got some options for you to keep it simple. Our Customer Experience team will be ready and able to assist! You've got a whole 180 days to try it first before the refund period closes.

How much is shipping?

We have absolutely free worldwide shipping. In some cases you can opt for ultra fast shipping for a small surcharge.

When will I get it?

Typically it takes around 2-14 days to arrive depending on where you are in the world.

Will I be charged customs/import duties?

We ship mostly from the UK, as well as some products from the US. As such some packages may be subject to customs/import charges. 

However, it is almost impossible for us to say how much these charges will be since they depend on the laws in your country of residence and the value of your package.

We are working hard to make our distribution centres available worldwide to reduce shipping times and customs charges.

We're proud to support the countries we ♥ by designing, sourcing & manufacturing all of our core products in the USA, UK & Canada.

THE Pro fiber is a 100% natural product. It is discreet, lightweight and conceals thinning hair and balding areas in just 3 seconds.

Manufactured in the USA under the most rigorous GMP conditions using 

ultra-potent, high performance high quality natural active-ingredients.
