Hero-ingredients

ANAGAIN
An active ingredient extracted from pea seeds (Pisum sativum) that has been shown to have several beneficial properties for hair. In short, it can help hair growth, contribute to thicker and stronger hair, improve hair quality and reduce hair loss.
Anagain is known for its hair growth stimulating properties. It helps to activate the hair roots and prolong the hair growth phase, which can help to reduce hair loss and promote healthy and fuller hair growth. By stimulating the hair roots and improving microcirculation in the scalp, Anagain can help promote thicker and stronger hair strands. It can be particularly beneficial for people who are experiencing hair loss or have thin and weak hair. Anagain can also have beneficial effects on hair quality. It can help to improve hair elasticity, shine and resistance to damage caused by environmental factors, styling and chemical treatments. Anagain has been shown to have a positive effect on reducing hair loss. By strengthening hair roots and improving the hair growth cycle, it can help reduce excessive hair loss and promote healthy hair follicle activity.

CAPILIA LONGA
A Natural extract of turmeric root, which can help to improve blood circulation to the hair roots, strengthen hair follicles and promote healthy hair growth. It contains active compounds including curcumin, which has proven anti-inflammatory properties. This can be helpful in reducing inflammation in the skin and in soothing irritation-related conditions such as acne, rosacea and scalp eczema.

CUCUMIS SATIVUS FRUIT WATER
Better known as cucumber extract, this ingredient is known for its moisturizing properties. It can help improve skin hydration by adding and retaining moisture, which can be beneficial for dry and dehydrated skin. Cucumber extract has a natural soothing and cooling effect on the skin. It can help reduce redness, irritation and sensitivity and relieve sunburn or skin irritation caused by external factors. Cucumber extract contains active compounds including flavonoids and antioxidants that have proven anti-inflammatory properties. This can be helpful in reducing inflammation in the skin and relieving conditions such as acne, eczema or rosacea.

How to

Apply two pipettes of hair serum to the scalp, right at the hair follicles and massage the product thoroughly in. Use morning and evening for best results.

One pipette corresponds to one press of the rubber cap. This means that one pipette results in there "only" being product in about 1/3 of the tube. Once you have drawn up one pipette - about 1/3 full tube - bring it up to the scalp and slowly distribute it, a few drops at a time, so that with two (or possibly three) pipettes you have the feeling of having the product distributed across most of the scalp. Then massage the product into the scalp. The scalp is where the magic happens!
If you only wish to use GROW Hair Serum in certain areas of the scalp, for example around the temples or on the top of the head, we recommend applying one or two pipettes to the area and a small amount - one pipette - to other areas of the scalp. This way you create an overall balance in the scalp, which is essential for reducing hair loss and for optimal regeneration of the hair follicles.

For real results, use GROW twice daily for a period of at least three months.

If you use two pipettes morning and evening, one bottle will last approximately 35 days.

GROW is Fantastic

I use it as directed on my brows, which were very thin and patchy before - a big change but not completely perfect yet, so I'll keep using it.
I bought a single one to try, but I'm now a subscriber

Had developed quite high temples, so I tried Cana Care. I’ve used it for just under three months and, sure enough, small, fine hairs have started to grow back, and my hair overall feels much healthier.

I think it works!!

After using it for six months, I've noticed a positive change. It sheds less, and the hair lasts longer before being shed. However, my impression is that you can't take long breaks—you need to use the product continuously.

Used for several years

I have used GROW for about 2 years and one week ago I cut a good length off my long hair because the new hair had grown so much out that there was a noticeable line between the old hair and the new hair. I still have long hair now, but it’s fuller and thicker. I continue using the product because it undeniably gives my hair good strength. Huge recommendation from me.

Maybe, maybe not

After a period of using a hairbrush that, after use, mostly left me with an alternate hairstyle, I started treating my scalp with drops from GROV. After 3 months, hair loss has reduced and my scalp is thriving. Whether there is new hair growth I find hard to assess, as I didn’t document with photos, but there’s no doubt that something has changed. I am now on the fourth bottle and will continue a little longer.

I've been using your GROW hair product since Dec 25… I feel there's finally a bit of visible improvement at the front and sides, with fine new hairs appearing. When I apply the product, my hair seems to get a little more volume 😊… So I hope it continues to stimulate growth 🤞

Good effect

I haven't had most of my hair for the past few years and I've tried almost everything with my hairdresser's advice without success. I bought Grow thinking at least I'd tried it. After about 4 weeks of use I had an appointment at the hairdresser. She ran her hands through my scalp and looked surprised. My hair has slowly started to gain volume—you can feel it 🥳 we'll keep going and see if we can get beautiful hair again.

Grow is good

I still shed a little, but much less than before. But the best thing about Grow is that my hair has become soft again and easy to manage... whereas before it had become incredibly dry and almost like straw.
So I'm a fan of Grow. Best regards, Anni

FAQ

How does the satisfaction guarantee work at GROW?

Try GROW for 100 days and get your money back if you don't see a difference.

We have only 2 requirements for you:

You must document the effect. Take one or more pictures of the area(s) you wish to treat before starting to use GROW, and then again after 1, 2, and 3 months, so you can visually see the effect - or lack thereof, should it unexpectedly not make a difference for you. All pictures must be taken from the same angle and in the same lighting.

Use the product regularly. You must use GROW every morning and evening for at least 90 days for us to guarantee the effect for you.

If you do not see the effect, send us an email with your pictures and your order number(s), and we will assist you from there.

Does GROW fatten my hair?

No, GROW does not make your hair greasy, so you can safely use it both morning and evening - even if you don't necessarily wash your hair every day 🙂

I experience that GROW separates/clumps - is that normal?

Yes! It is completely normal and fortunately has no impact on the product's effectiveness. Because GROW is a concentrated hair serum created from good, natural ingredients, there may be some separation of the active ingredients, which can appear as "grit" or small flakes in the product. If you experience this, simply ensure the lid is tightly screwed on and shake the bottle well before dispensing the product into the dropper. This ensures that the active ingredients are evenly distributed, maintaining consistent effectiveness every time you use the product.

Can men use GROW?

YES! GROW helps reduce hair loss in both men and women, so if you are a man (or if you know a man) who has started experiencing hair loss, now is a great time to start using GROW. In addition to helping reduce hair loss, GROW also supports natural, healthy hair growth. For more information, see HERE.

About the product

Hair loss - among both men and women - is often a very taboo subject. Our hair isn't just about how we look. For many, part of our identity and sense of self-worth lies in our hair. So, what do we do when our hair doesn't grow the way it used to? Or if it falls out? The answer is not straightforward, but as with most things when it comes to our bodies, the best we can do is to give our body optimal support, both internally and externally. A healthy and varied diet, plenty of water and great fatty acids - and a good, concentrated hair serum that can provide the scalp and hair follicles with the best possible conditions for healthy and beautiful hair.

GROW Concentrated Hair Serum from Cana Care may very well become your best buddy in the bathroom. At least if you dream of healthy and luscious hair.

GROW is a concentrated hair serum that with its unique composition of ingredients not only contributes to reducing hair loss, but also to stimulating and promoting the regeneration of hair follicles.

This product contains, among other things, Capilia Longa and Anagain, which have clinically proven effects.

Studies show

Research on the effects of Anagain conducted by the Skin Test Institute in Switzerland showed the following:

A decrease in hair density in telogen phase observed in 85% of participants.
Increased hair density in anagen phase observed in 75% of participants.

An increase in the growth coefficient (ratio between the number of anagen hairs and the number of telogen hairs) observed in 85% of participants.

After three months of use:

85% noticed slight to strong hair regrowth.
95% noticed a slight to substantial slowdown in hair loss.
80% experienced that their hair was less prone to breakage.
70% felt their hair was more resilient.
95% noticed a small to large improvement in the appearance of their hair.
