I used this product once but am still going to leave a glowing 5 star review on behalf of my 25 year old son who basically saw the word thickening and swiped the shampoo and conditioner never for me to be seen again. He however loves it and said he's going to keep using it!

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

I have been using this conditioner on a daily basis for 2 months now. It is a wonderful product, the conditioner is thick and creamy, and you don't need to apply much. It rinses out easily leaving my hair feeling both refreshed and when dry full bodied. People have commented on how my hair now looks thicker.
Would definitely buy this conditioner again.

I used this along with the THIX shampoo. I have thick, coloured hair which can go frizzy in hot weather. I loved this shampoo and conditioner. The texture is just right, the conditioner has a handy pump dispenser. 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 the shampoo and conditioner for two months and am really pleased with the results. Leave on for three minutes while it does its thing and, voila!- thicker, bouncy, shiny hair.
I love the way the conditioner smooths and gives my hair a fresh, bright look. Aluminium bottle for sustainability also gets my vote. Hair does feel thicker using both products in the range - welcome after menopause!

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

I've been using this conditioner for about 4 weeks my hair feels amazing so much thicker than before, a little goes a long way and my hairdresser has noticed what great condition my hair is in. The pump dispenser looks very chic in my bathroom

I have now been using this conditioner in conjunction with the shampoo 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".

This conditioner makes my hair feel great. My hair feels soft and less tangled

I decided to try a caffeine shampoo and conditioner for the first time recently and opted for this one. This conditioner has a pleasant fragrance and is not too pungent - just a lovely fresh smell! I normally need to use a lot of conditioner on my hair and usually run out of conditioner before shampoo (even though I shampoo twice before conditioning) but this was not the case here. I actually found that a little goes a long way, giving better value.
The conditioner left my hair feeling silky soft when still wet (I often leave my hair to air-dry) but then soft and shiny once dry. I cannot comment on thickness as yet after using for 6 weeks, but my hair feels clean, stronger and softer! Love the fact the product doesn't come in a plastic bottle either.

I have tried the shampoo and conditioner for 4 weeks and noticed a difference after 2 weeks. My hair is thicker and less fly away.
I have very dry ends and had to use a hair mask once a week as well, but as a normal conditioner it did a great job.
The bottles are metal which is so much nicer than plastic. The smell is clean and not flowery so my husband would happily use it too.
I am happy with the product and results and will buy again.

Been using this conditioner for 2 months and love it!
Nicely packaged in attractive aluminium bottle which is recyclable. Important when cutting down on plastic
Washed with the matching shampoo then conditioned, leaving in for 3 minutes as it gets to work smoothing and nourishing. Left my hair silky smooth and hydrated and my hair feels much thicker after using these products consistently.

I've been using this in conjunction with the THIX Caffeine Shampoo for the last 6 weeks or so. I like the pump dispenser it comes with, makes getting it out so much easier. It is easy to massage into wet hair and washes out well, leaving my hair feeling so soft. I would definitely recommend this product.

I've used this conditioner, paired with the shampoo, for around 6 weeks and I can't say my hair feels any thicker or stronger yet. Generally it cleans well and the conditioner leaves my hair feeling soft and shiny. I like it as a conditioner but I'm not sure if it is worth it for the price for me.

Again as for the shampoo - left hair lovely and shiny and nice consistency and smell. Not sure my hair feels thicker yet! Will continue to use

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've been using this product for around 5 weeks and haven't used anything else, its made my hair feel softer and healthier.

This product is brilliant and balances out the stripping effect when using the shampoo. It is thick and moisturising to the hair.

Hair felt thicker with first wash, only a small amount needed.

I used this alongside the shampoo for a month and my hairdresser was the first to tell me my hair is now thicker! I love the fresh scent and my hair feels lovely soft after using it. You don't need to use much product so it will last a long time. Definitely a regular purchase from now on, alongside the shampoo. Great value for money.

This is such a brilliant conditioner, it makes and leaves my hair feeling so soft and curly. Love it

I have been using this for 4 weeks now, when applied you instantly feel the smoothness.
Hair remains tangle free, though I did notice hair became greasy quicker.
Bottle is a bit clumpy and the pump make only releases a small amount at a time.
Love the smell.

Feels really nice after the shampoo, the shampoo feels quite drying on the hair but paired with the conditioner it feels great

I'm usually quite sceptical of hair products that claim to add volume, but this conditioner worked really well alongside the shampoo. It smells amazing and left my hair feeling soft without weighing down the lengths. The only thing I found was that I had to be really thorough when rinsing it out, otherwise my roots seemed to need washing a bit sooner than usual. Used together with the shampoo though, they made a great combination and definitely gave my fine, straight hair a bit more body.

I have afro hair and I have been using this weekly for about 4 weeks. The smell of this conditioner is lovely, I like the combination of mint and eucalyptus. It's not too overpowering, like a calming scent.
I used about a tablespoon of this conditioner and used it from root to tip, even though it says the other way round. This is way just works better for me and my hair. This conditioner has plenty of slip and you do not need to use a lot of it which is great.
When washing it out my hair felt a lot softer and after using this for 4 weeks I have noticed my hair is a lot fuller than before and there has been less breakage. My curls are starting to bounce back too.
This conditioner is great for afro hair for when you're doing a regular wash. I will be purchasing this again as I have seen a real difference in my hair.

The smell of the product was fabulous however I found it made my hair feel very dry after using

I've been using this conditioner for a month and my hair feels nourished and thick. It's a super-thick consistency, definitely worth leaving on for a good 3 minutes before rinsing off. I'd definitely recommend this to help strengthen your hair, of any length.

This conditioner leaves my hair feel so hydrated and nice! I've been using it a while now and have had so many compliments regarding my hair being asked what I've changed

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. The conditioner makes your hair super smooth and it also feels so clean after each use.

I like the recyclable bottle.

The conditioner itself is fresh smelling, nice in the summer as it doesn't feel too heavy.

My hair is soft and shiny when dry.

I wanted to like this conditioner as companion to the shampoo but like the shampoo the smell is overwhelming! Using the pump as recommended is difficult as the conditioner is quite thick and difficult to get out.
