I would be lying if I said this was my own review, because I used the shampoo once before my 25year son and his girlfriend nicked it for there holidays (yes two) however I asked them and they love it, he said is hair was much easier to manage as it's longer then average! He said he used less stuff to get it to stay in place!! I'd say that's a good result and a great review lol

I use the caffeine shampoo and conditioner and my hair feels amazing! Its made my hair feel so soft and strong and the eucalyptus scent makes the shower smell like a spa.

Have been using this shampoo for 2 months and have noticed a marked improvement in my hair condition. I swim most days, not the best thing for my hair, but this shampoo seems to counter the negative effects of a chlorinated pool, hair looks visibly thicker.

I used this along with the THIX conditioner. I have thick, coloured hair which can go frizzy in hot weather. I loved this shampoo and conditioner. The texture is just right, the shampoo lathers up nicely. Afterwards my hair was so much more manageable and shiny. I have ditched my old shampoo and conditioner for this now! Packaging of the bottles is also very cool and recyclable. Great products!

Used this shampoo over 2 months. The results have left my hair feeling thicker than ever- welcome after going through the menopause.
The shampoo sits for three minutes and you can feel a slight tingling. Hair has been strong and sleek since using.
The aluminium bottle is modern and eye catching and recyclable- much better than plastics littering the oceans.

Fab product , really thick and creamy when put on hair feels expensive and great hair after using - just wish the bottles were bigger as for a family not big enough

This shampoo is amazing, from the packaging to the smell but best of all is what great condition my hair is in, its shiny and feels so much fuller, no more washing then tying it straight up

I have now been using this shampoo in conjunction with the conditioner for 6+ weeks. My hair feels thicker and I am wearing it down so much more than before. The icing on the cake was when I went to my regular hairdresser and (without me saying anything) she exclaimed that my hair looked "so much fuller".

The shampoo has a strong scent which could be overpowering to some. However, I did feel the tingling sensation and areas of where my hair was thinning is visibly thicker after frequent usage of the shampoo

I have not tried a caffeine shampoo before so thought I would try this now I am entering the stage in my life where I am losing a little more hair than I used to!
I love the fresh but not overpowering smell of this shampoo - it does not give you that all-over tingly feeling that other products might do, but my hair and scalp feel super clean after use, compared to other brands. I cannot comment on the thickness of my hair after using for 6 weeks, but my hair feels noticeably stronger and healthier. I don't actually need to use too much either as it lathers up well (I live in a hard-water area, so this is a bonus). I love the fact the shampoo doesn't come in yet another plastic bottle either!

I tried this shampoo as a menopausal woman with fine, thinning hair.
The bottles are metal and nicer than plastic. The shampoo itself smells clean and medical and my husband was more than happy to use it too.
I did feel a difference to the texture of my hair having used the shampoo and conditioner for 2 weeks. I have quite greasy hair and have to wash it every other day and this did not change with Thix shampoo. With other volume shampoos I have tried, I have had to wash every day.
It’s not a miracle cure, but definitely made my hair feel thicker and less fly away.

Have been using this shampoo for 2 months now and really like it. Good sturdy aluminium bottle that's attractive and recyclable - important when cutting down on plastic and landfill.
It gives your scalp a lovely tingle as it works its magic and leaves hair well cleansed. I followed with the conditioner for perfect results

I've been using this in conjunction with the THIX Caffeine Conditioner for the last six weeks or so. I'm not a fan of the screw cap - its fiddly with wet hands and once open, if its knocked over accidentally you're going to lose a lot of shampoo (this did happen to me). That said, it soaps up ok and washes out well. My hair does feel thicker and my hairdresser said so too, so I would definitely recommend this product.

After using this shampoo for 6 weeks or so I can't say my hair feels any thicker or stronger. It does clean well and my hair doesn't get as greasy as quickly. It doesn't lather as well as most shampoos so does feel a little bit more work. For me, I'm not sure it's worth it for the price.

I have been using this shampoo for over a month - it leaves my hair feeling very clean but not necessarily much thicker. Will continue to use and I love the fragrance!

I have issues with my scalp and dry skin and this has actually been a god send, cleared my scalp completely made my hair feel nourished and fresh and I can't remember the last time I left the shower feeling this way and it not being like rats tails

I use this product almost daily and it has made a real difference. It smells great, and comes in a really premium-feel bottle, but ultimately it has made my hair feel thicker. Even my barber has commented on the difference from one hair cut to the next!

I've been using this for 5 weeks and its made my hair softer and healthier.

Pros: this product really really works! My hair did not come out anywhere near as much during wash or brushing. It also left my hair really glossy.

Cons: I cannot wash my hair daily and unfortunately do not have the time. The shampoo was extremely stripping which worried me initially but the conditioner saved the day.

Along with the conditioner this works! Left hair feeling so much thicker with first wash. My hairdresser even asked what I have been using.

I was excited to try this shampoo and conditioner set because at 50 years old my hair is thinning. The scent is beautiful, so fresh and zingy! My hair feels very clean and this feeling last a few days until my next hair wash day. After a month of use my hairdresser commented that my hair is thicker and I couldn't be happier with that! This is definitely going to be a regular purchase, great value for money.

I used this for 2 weeks, while it makes my hair feel brittle it seems to be thicker.

I have been using this for 4 weeks. The bottle is clumpy and with a screw lid, hard to use with wet hands
The 3 minute leave on seems long especially when using conditioner as well which also had 3 minute leave on.
Hair felt and smelt clean, hair did become greasier quicker when used with the conditioner.

Feels refreshing on the scalp but quite drying on the hair, paired with the conditioner tho it feels good but would deffo recommend using the conditioner with it

I'm always a bit sceptical of hair products that promise more volume, but this one actually worked! I have really fine, straight hair, so I was keen to give this shampoo a try. It smells fantastic, and my hair definitely felt like it had a bit more oomph after using it. I also recently had my hair cut into a short bob, so I'm sure that helped too, but combined with this shampoo, my hair feels much fuller and has more body. I'd happily recommend it.

I love that the shampoo is in a aluminium bottle, less plastic is good for the environment.
I opened this shampoo and the smell of the mint & eucalyptus is really nice. Its not overpowering, it's just a nice calming scent. I used this shampoo once a week as I have afro hair, so I used this shampoo every week for 4 weeks.
I poured about a tablespoon into the palm of hands and rubbed them together, this shampoo is nice and thick. When putting it on my scalp and hair, I noticed a nice tingling sensation and it felt like my scalp was getting a nice clean. There wasnt much lather happening, but that could be because my hair was dirty from build up of oils. The 2nd shampoo did have some lather, and the suds were clear when washing out. My hair and scalp felt clean and there was no more build up in my hair. My hair felt a little dry, but I have been dealing with a little damage to my hair so that could be the reason.
After using this shampoo for 4 weeks, I have noticed a difference, my hair isnt so dry and the damage to my hair has gotten a lot better. This is great clarifying shampoo for my hair, I haven't used a moisturising shampoo alongside it as I wanted to see the real benefits of this shampoo. I think I will make a switch and continue to use this shampoo from now on, my hair feels so fresh and clean after. My hair is a lot fuller too

The product smelt very good and the pump was useful however there was only one pump, the product smelt really good but left my hair dry

I've only been using the shampoo and conditioner for three weeks so a bit early to say that it's definitely improved the volume but compared to other caffeine products I have used, these are by far and away the best to date. The shampoo lathers really well and you don't need to use much of it. The conditioner has a creamy texture and both smell divine. My hair feels a lot healthier and is super soft. Time will tell if the volume increases but I will keep using these products anyway if only to maintain condition

The mint and eucalyptus scent is gorgeous - quite zingy but not overpowering. The shampoo cleans my hair really well, though I've not often got time to leave on for 3 minutes or more as instructed - nonetheless my hair felt nourished and soft. The bottle is a convenient size to pack for a weekend away but it being metal I did worry about dropping it in the shower for fear of breaking something. It's quite a runny consistency and a little will go a long way.

This shampoo makes my hair feel so clean and hydrated whilst also leaving a lovely smell in my hair that last for ages!

I have only been using this product for 4 weeks but can certainly see a few small changes, as someone who lost a lot of hair in pregnancy and can feel it thinning now further due to peri menopause. My hair condition feels better with less breakage and split ends, i will continue to use and hope to see further results.
