5 in 1 description


This innovative indulgent mask treats the scalp and hair with scientific ingredients, such as hyaluronic acid, argan oil and keratin for healthier growth and visibly improved fullness.

With a soothing fragrance, it’s perfect for professional at-home pampering. This mask is for women wishing to stimulate hair growth without the laborious need for intensive styling and finishing.

Thicker and healthier hair growth is achieved over time, with Nanogen’s unique Hair Growth Factor complex.

Nanogen’s unique Hair Growth Factors explained:


Revitalises hair follicles and prolongs the anagen growth phase of the hair’s cycle. Supporting the follicle’s ability to feed the hair means growth is sustained for longer.


Stimulates the production of hair cells. Hair becomes thicker and more dense.


Stimulates collagen around the follicles, facilitating hair anchoring. Hair shedding is reduced for better overall thickness.


STEP 1: After cleansing with Nanogen Thickening Shampoo, apply to damp hair.

STEP 2: Massage a generous amount into the scalp, running through the lengths of the hair from root to tip.

STEP 3: Leave the mask on for around 20 minutes or longer if desired.

STEP 4: Rinse thoroughly and follow with Nanogen's Thickening Hair Treatment Conditioner for women. Style as desired for instant shine, thicker and volumised hair!


What is the difference between the Hair Growth Factor Treatment Serum and the Hair Growth Factor Treatment Mask?

Although both products contain Hair Growth Factors, the serum contains the highest amounts amongst all Nanogen products. We recommend you use this as a long-term treatment every day. The mask we recommend to use as a pampering treatment for your hair up to twice a week. Enriched with hyaluronic acids, it intensely moisturises the hair giving incredible condition and shine; making it look instantly thicker and full of volume. It is also packed with unique Nanogen growth factors which encourage healthy hair growth.

Am I able to use your Hair Growth Factor Treatment Mask alongside other Nanogen products?

All our Nanogen products are perfectly compatible with one another. The mask can therefore be used alongside all other products of our treatment and styling ranges.

Is your Thickening Mask suitable to use on coloured hair?

Our Thickening Mask is suitable for coloured hair, however we suggest that you use our mask twice a week.

Do you test on animals?

Nanogen are against animal testing and no finished Nanogen products are tested on animals.

Do your products contain parabens?

While we do not believe parabens are harmful, we understand that some customers are concerned about using them. Therefore, our entire product range is paraben free.

    I’ve only used this product once but can already feel the benefits. It left my scalp feeling moisturised and my hair nicely conditioned.
    It has a pleasant faint smell and washes out easily without feeling greasy. The only thing I wasn’t sure about was how much I should use. What constitutes a “generous amount”? For someone new to these type of products, a bit more clarity on how to use it would be great.

    Only used the mask a couple of times, but was the most relaxing experience all around. My hair already looks and feels more conditioned than just using the shampoo. My only reservation is that I wish there was more in the pot - which by the way is a piece of art itself.

    I really like the smell and the feel of my hair after using it. I used it now for a couple of times and my hair has a really nice shine and volume after, I would definitely recommend it if you are searching for a hair mask that nourishes your hair without having a greasy-feel after.

    Healthy Hair Treatment

    I am coloring my hair blond since more than 10 years and therefore constantly fight with dry/ damaged ends that need to be cut off often. That's why I gave this mask a try - to support hair growth and to pamper the hair in general. I use the mask in the evenings; after the application I put tin foil around the head and a towel on top and then leave it in for an hour. I can definitely say: I love its smell, it reminds me of my hair dresser appointments, since I can still smell it in my hair the next day. Yet, one negative point: I felt I need to use a lot of the product, almost as if the consistence wasn't smooth enough. I also felt it wasn't too easy to wash it out again, but it's not like you feel the hair is heavy or greasy once everything is fully rinsed. The hair really feels great afterwards, it is soft and looks nourished. I cannot say it supported the hair growth so far, but I just started using it 3 weeks ago, and I definitely think that hair grows faster if scalp and hair are healthy. I can really recommend this mask, especially for people who want to support the health of their hair!

    My new favourite treatment in my hair care regime!
    Review by on
    I absolutely like this mask and recommend it to everyone who wants to give their hair a bit of TLC. I've been looking for a treatment to you use on both hair and scalp for ages. All products I've tried so far I could only put on mid-length and ends, as otherwise my hair would be weighed down and get greasy easily. I use the Nanogen Women's Shampoo, which I really like as well, so thought I give their mask a go, as it's meant to nourish your hair and scalp without overburdening it. I have to say, once again they keep up to their promises with this thickening mask. I've used it a couple of times now, always after shampooing the hair. I leave it in for 20-30 minutes then rinse it off. It washes out easily and leaves the hair soft, nourished and tamed. No sign of frizz, but healthy volume instead. Thumbs up Nanogen!
