Frequently asked questions

What is The Hair Fuel?

The Hair Fuel is an all-natural, vegan and cruelty-free hair growth mask, which supports hair growth and hair health from the roots of your hair.

How does the hair treatment work?

The Hair Fuel works by improving blood flow to your scalp and hair follicles. The blood vessels attached to the derma papillae – or the “hair root” – carry nutrients and oxygen to the hair, supporting its growth and health. The Hair Fuel works in 2 ways:

(1) stimulating the blood flow
(2) delivering the nutrients from the mask as well as your own body – directly to your hair follicles

How do I apply?

The product comes with full set of instructions. Here they are:


The Hair Fuel – Preparation How-To
  1. Fill the applicator bottle with 30ml or 2 tablespoons of warm water – which fills up about one-third of the bottle we provide.
  2. Add contents from the powder and oil sachets into the bottle.
  3. Close the lid of the bottle. Shake for 15-20 seconds, until the mix becomes universal in texture and all the lumps are gone.


The Hair Fuel – Application How-To
  1. After mixing up, apply Hair Fuel to scalp directly from the bottle and roots only, avoiding the lengths.
    1A: Tip We recommend applying a conditioner, or nourishment oil on the lengths of your hair before putting on the shower cap – to prevent from drying and to nourish it as The Hair Fuel does its hair growing magic on your roots.
  2. Cover your hair with a shower cap and then a warm beanie hat or a towel if you don’t have a hat.
  3. Leave for 45 minutes.
  4. After the elapsed time, rinse your hair thoroughly with warm water, and then follow with your usual shampoo and conditioner routine.

How long does the preparation and application take?

It takes around 5-7 minutes the first time – mixing and applying. As you continue using it, you become accustomed to the process and it wouldn’t take you longer than 2 minutes to mix it all up and apply.

How long do I leave the mask for?

45 minutes. Depending on whether you can take the heat or not, you can either cut down that time, or increase as you become more accustomed to the sensation.

How often should I be doing it?

We recommend using The Hair Fuel weekly, pick a night during the week which you can commit to spend 45 minutes to have the mask on. We prefer Monday night to establish a little self-love and self-care ritual: think face masks, doing a manicure-pedicure as you wait for The Hair Fuel to work!

I feel tingling, warming, burning sensation when I apply The Hair Fuel, is it normal?

Yes! This is normal and expected. You might feel a tingling, warming or even burning sensation on your scalp once you applied Hair Fuel. It is the sign of that The Hair Fuel is activated and working!

What if the sensation becomes too much?

If heat becomes unbearable before recommended time has elapsed, wash the mask off. Don’t worry, as you continue using The Hair Fuel regularly, your scalp will get used to the heat and sensation. In the meantime you can add slightly less powder top it off with extra olive oil.

My scalp is red after I washed it off, is it normal?

Yes! After washing off, you might notice reddening of the scalp. This is an indication of increased blood flow to your hair follicles and also a sign of The Hair Fuel working! Your scalp will calm down within 24 hours of mask application, depending on your skin sensitivity.

Do I need to wash my hair beforehand?

No. We recommend you apply it on unwashed, dry hair and then follow up with you usual shampoo & conditioning routine.

Does my hair needs to be dry before applying?

Yes. Apply it on dry hair.

Can I apply it on the lengths of my hair?

It’s a waste of our mask if you apply it on lengths. In order to improve hair growth, you need to focus on the roots. If you want to treat your hair lengths while The Hair Fuel is working on your roots, we recommend covering the lengths of your hair with natural hair oil (take our Hair Quiz if you want to find out which hair oil is best for your specific hair type) or a silicon-free leave-in conditioner.

Do I still need to shampoo and condition after?

Yes. We also strongly suggest to apply on unwashed hair, to save you from washing your hair twice and therefore over-drying it. Once 45 minutes elapsed, follow with your usual shampoo and conditioner routine.

Is it suitable for thin / thick / coarse / coily / curly hair?

Yes. Our mask is suitable for all hair types, as it works with blood flow and focuses on the roots, it does not matter what texture your hair has.

I have dandruff, wounded or irritated scalp – can I use The Hair Fuel?

We advise against using The Hair Fuel on irritated and wounded scalp. Results for people with dandruff can vary, depending on the root cause behind your dandruff. If you decide to use it, do so at your own risk – if the condition worsens – discontinue using it.

What’s in the box?

First month subscription box contains: welcome card, 4 powder sachets, 4 oil sachets, measuring tape, shower cap, mixing bottle, instructions card and science card. Subsequent months boxes only contain 4 powder sachets, 4 oil sachets and a welcome card.

Why don’t I have bottle and shower cap in my other boxes?

We love Mother Nature and hate waste, so our shower cap and bottle are made from a durable material which means you can rinse them with lukewarm water and soap after each use and let it fully dry. You can use the shower cap also for applying other masks and treatments, too!

I lost my shower cap and / or bottle, what do I do?

Pop us an email – with your request. You might need to pay a small fee for these as well as shipment. The reason behind is that we want to encourage re-using the cap and the bottle as much as possible.

Which subscription bundle should I buy?

If you’re growing your hair out for an event, the earlier you start, the more time you have for your hair to grow. One of the recommended ways for The Hair Fuel is doing 3- or 6- month packages once a year as a way to support your hair growth. However, it is also perfectly fine to use it weekly throughout the year!

Can I use it more often than once a week?

You can use The Hair Fuel up to twice a week, drop us an email to if you need an accelerated package.

Will my hair be greasy after?

No, as long as you follow up with your shampoo + conditioning routine after using it – your hair will not be greasy. The combination of the components actually have been reported as helping with oily scalp and regulating sebum production.

What is the full list of ingredients?

Olea Europaea Fruit Oil, Ricinus Communis Seed Oil, Sucrose, Brassica Alba Seed Extract, Brassica Juncea Seed Extract, Oryza Sativa Powder, Capsicum Frutescens Fruit Powder, Caffeine, Mentha Piperita Oil

I have a medical condition, or recovering from a medical treatment, can I use The Hair Fuel to help re-grow my hair?

We advise consulting with your physician / GP showing them the ingredients list and explaining that the mask works with the blood flow in scalp.

Is it tested on animals?

Absolutely not. Never.

Is the formula vegan?

Yes, the formula vegan and cruelty-free.

Is the The Hair Fuel acceptable to use with chemically straightened/dyed/bleached hair?

Yes. Especially if you are trying to grow out your hair – you will notice your faster growing roots. The Hair Fuel is applied to the roots of your hair, and because chemically treated hair is already damaged, we highly recommend using natural oil (e.g. grapeseed) applied on the lengths of your hair prior to the application of our mask. If you have very light (e.g. white) bleached hair – some yellow coloration may occur. This goes away after a wash and in the case of white bleached hair – using of the purple shampoo as instructed by your hairstylist – is recommended.

Where do you source your materials from?

Our ingredients are sourced from the UK and EU.

Where is The Hair Fuel manufactured?

In the UK and the Netherlands.

What is the shelf life of your products?

Each sachet has a typical shelf life of 12 months. If our products are kept out of direct sunlight and at room temperature or below, they will stay fresher longer.

Any storage tips?

Store below 30°C, wash the shower cap and bottle when not in use with lukewarm water and soap – and let it dry between uses.

Do you guarantee results?

While we cannot guarantee a specific length you will achieve – as every person’s hair follicles are different, we do have 30 day money back guarantee on all subscription bundles. If, for any reason, you are not happy with the product, email us to – we refund you the money and you can keep the mask.

Is it suitable for males?

Yes. Due to higher androgens in males, The Hair Fuel would always work better for females as any other hair growth product, our mask contains caffeine – a known DHT blocker, as well as peppermint oil which is known to help male-pattern baldness.

Can it be used on children?

While our mask is for everyone, children may not be accustomed to the burning / tingling sensation on their scalp.

Can I sleep in the hair mask?

We don’t recommend it, however you can leave it for longer than 60 minutes if you wish!
