"lots of tiny new hairs coming in..."

Verified Purchase

By David, W

"The Biogaine kit is a game changer. I've got lots of tiny new hairs coming in all along my hairline after 4 months"

What if you could combine the most powerful, non-pharmaceutical hair growth stimulants all in one bottle?

At Hairguard we've spent over 3 years researching and testing the most effective hair growth topicals in the world.

Now finally, you can get everything you need to regrow your hair, in one bottle. We've spared no expense to make this the best in the world. 

Biogaine contains the most effective and powerful, proven hair growth stimulants on the market for those who don't want to use minoxidil.

Combine this with the Dermaroller and Scalp Brush that come included in the Kit and you've got a powerful new way to reverse hair loss by activating the hair follicles back into the growth phase, leaving them thicker and stronger and promoting new hair growth.

Biogaine gives your hair everything it needs to support, thick healthy hair growth, but without the complications from pharmaceutical ingredients.

The Kit is simple and easy to use. Use the Scalp Brush for 3 minutes and then apply Biogaine straight after. Once per week use the Dermaroller instead of the brush, still applying Biogaine afterwards. Allow to dry for ten minutes and you're all done.

Our formula is non-greasy, easy drying and with a subtle, natural smell, that won't irritate your scalp.

Life's better with thick, healthy hair.

When we began developing Biogaine, we asked ourselves a simple question: “What is the best natural hair growth product we can possibly make?”

The result is Biogaine, and it has exceeded our expectations. The exhaustive list of proprietary and patented ingredients work synergistically to stimulate hair regrowth from multiple angles, whilst blocking DHT at the same time.

What makes Biogaine so powerful?

We've spent years researching, developing and refining the formulation for Biogaine, making it the ultimate all-natural product for men and women that are suffering from hair loss.

Below are the top 6 ingredients in Biogaine. All 6 have been shown in scientific studies to either stimulate new hair growth, block DHT, or both. If they didn't work then we wouldn't include them. It's as simple as that.


Redensyl is a breakthrough ingredient with extensive clinical backing. In vitro, Redensyl has been shown to stimulate the hair follicles into anagen (growth) phase, whilst also enhancing the division of the hair follicle bulge stem cells

In a small study spanning 84 days, in which Redensyl was used for the treatment of hair loss, volunteers experienced (on average) a 9% increase of hairs in anagen growth phase and an average 8% increase in hair density.

Red Clover Extract

This extract has been shown to help improve hair growth through several pathways, such as inhibiting DHT production to reduce androgenic alopecia and improving hair anchorage to the Dermal Papillae.

In an independent study investigating just Red Clover Extract, over the course of 4 months the number of hairs in anagen (growth) phase increased by 15% compared to the placebo, and the number of hairs in telogen (resting) phase decreased by 52% compared to the placebo.


Caffeine has become a popular addition to anti-thinning shampoos, but the problem is that it doesn't stay in contact with the scalp long enough to have noticeable benefits. Since Biogaine is left in overnight, the Caffeine has much longer to reach the follicle and stimulate hair growth.


Adenosine has been shown in multiple studies to significantly increase hair growth. In one study growth increased by 40% in just 6 weeks. Adenosine has also been shown to work synergistically with Caffeine.

Pea Sprout Extract

Pea Sprout Extract has been shown to stimulate specific signalling molecules in the Dermal Papillae which are required to initiate the growth of a new hair, such as FGF-7 (fibroblast growth factor-7).

In an independent study investigating just Pea Spout Extract by itself, 95% of the volunteers noticed a slight to strong deceleration of their hair loss, and 85% of the volunteers noticed a slight to strong regrowth of their hair after just 3 months.


Zinc is an important ingredient because it is a potent DHT blocking ingredient. In one study, Zinc inhibited the 5-alpha reductase enzyme by over 90%. For this reason we include it in our formula as blocking DHT helps to stop the process of dermal fibrosis.

Zinc has also been shown to increase the incorporation of cystine in hair proteins, and deficiency in zinc is associated with hair loss

Frequently Asked Questions

How do I use the Biogaine Kit?

Before bed each day you'll need to use the Scalp Brush for 3 - 5 minutes. Then simply apply 1.5ml of Biogaine and rub it in with your fingertips. 

Once a week, use the Dermaroller for 5 minutes instead of the Scalp Brush (you'll still apply Biogaine afterwards). That's it.

How long does the Kit last?

The kit lasts for 2 months. You will receive a full replacement kit (Biogaine, Scalp Brush and Dermaroller) every 2 months automatically, but you can easily pause, edit or cancel your subscription in your My Account area.

Is Biogaine different to the Scalp Elixir?

Yes it is. The new Biogaine formula has similarities to the Scalp Elixir, but in general is much more sophisticated and powerful.

This is because Biogaine contains many more active ingredients and they have all been shown (in studies) to either promote hair growth or help to block DHT. The main reason the Biogaine Kit is expensive is because the Biogaine serum is very costly for us to produce because it has so many of these high-quality ingredients.

One example is Adenosine, which has been shown to regrow hair as effectively as Minoxidil when used in conjunction with Caffeine (which is also included). Adenosine costs around £1,900 per kilogram. Most companies wouldn’t use it because it’s so expensive, but we really feel that it’s a great ingredient so we have included it at the clinically-relevant dosage.

We have many examples like this. The result is that Biogaine is much more effective than the Scalp Elixir.

Can I buy just the Biogaine topical?

We only offer the Kit as a whole, not jus the topical. 

We include the Dermaroller and Scalp Brush because we want you to get the best results possible. Since Dermarolling has been shown to triple the effectiveness of topicals we include one for free so that customers can easily incorporate it into their routine and therefore easily reap the benefits.

The Scalp Brush helps to remove epidermal plaque, making it easier for the active ingredients to penetrate to the hair follicles. 

Together these additional products make the Biogaine solution even more effective, which is why we want everyone to use them and therefore offer them together as a single Kit.

Does this work for women too?

Yes, the Biogaine Kit works extremely well for both men and women suffering from pattern hair loss because it treats the underlying cause of hair loss which is the same for men and women (scalp tension), whilst simultaneously stimulating regrowth.

How long before I start seeing results?

Although it varies for everyone, the typical amount of time for the hair follicle cycle to begin is 90 days so you should begin to notice a difference within 3 months.

Will I lose all my gains if I stop using Biogaine?

The beauty of the 3 Layer System is that it treats the true underlying problem that's causing your hair loss in the first place. This means that once you've achieved your hair goals you should be able to stop using Biogaine altogether (assuming that you've addressed the scalp tension in layer 3), and instead you'll only have to do an abbreviated maintenance routine to keep what you've got.

How long will it take to arrive?

We currently ship from both the UK and US. Domestic orders usually take 3 days to arrive. International orders usually take a bit longer, up to 10 days depending on where you live.

What is the full list of ingredients?

Biogaine was developed to be the most effective all-natural hair loss topical on the market. It contains the following ingredients: 

Water, Magnesium Chloride, Niacinamide, Caffeine, Adenosine, Pisum Sativum (Pea) Sprout Extract, Glycine Soja (Soybean) Germ Extract, Triticum Vulgare (Wheat) Germ Extract, Larix Europaea Wood Extract, Glycine, Zinc, Propanediol, Glycerin, Alcohol, Arginine, Lactic Acid, Xanthan Gum, Epilobium Angustifolium Flower/Leaf/Stem Extract, Scutellaria Baicalensis Root Extract, Butylene Glycol, Acetyl Tetrapeptide-3, Trifolium Pratense (Clover) Flower Extract, Potassium Sorbate, Sodium Benzoate, Sodium Metabisulfite, Tocopherol, Dextran

As part of our commitment to innovation we update our formulations regularly. As such, this ingredient list may vary from the actual ingredients in the bottle you receive. Please check the label on the bottle you receive as it will have the correct list of ingredients.

Why is the Biogaine Kit more expensive than the Scalp Elixir?

It's more expensive for two reasons:

To provide some context, the whole idea behind the Biogaine formula is that we wanted to make the most effective all-natural product possible. The problem with hair loss is that it’s a really hard problem to fix, so it takes a lot to stimulate the amount of hair growth that we're aiming for. This has meant we’ve had to pack a lot of firepower in the formulation, so to speak.

The whole formula is actually much more sophisticated then the Scalp Elixir. It’s uses more ingredients, and those ingredients are more powerful (such as Adenosine - see above).

The second reason it is expensive is that you also get the Dermaroller and Scalp Brush in the Biogaine Kit, which you don't get with the Scalp Elixir. We include these because they help treat Layers 1 and 2 of the scalp, thus helping to reverse the true root cause of hair loss.

And in the case of the Dermaroller, it has been shown to increase the effectiveness of topicals by as much as 3x, so it really is a game-changer when it comes to stimulating regrowth.

As such, we've wanted to include these products in the Kit with the topical so that it is convenient as possible for customers to reap the benefits and get the best results.

Are there any side-effects?

Since Biogaine is derived from all-natural ingredients the chances of side effects is very unlikely. In some rare cases minor irritation can occur for some people, but this usually subsides over the course of the first week and is not a problem.
