Great delivery and easy to order
Great delivery and easy to order, it's expensive and probably the limit of what I'd pay for it, but a great product and service.

Amazing styling paste
I’ve been using there products for a couple years now. The shampoo and conditioner is great however their texturising paste is my favourite styling product. I have naturally very straight hair and it isn’t the thickest and I find the paste offer a strong hold and makes my hair look a lot fuller with the added bonus of its ingredients being great for your hair. 10/10 recommend!

Initially
Initially, I wasn't very impressed. After months of waiting for it to become available, it arrived poorly packaged and covered in dents. It was meant to be a gift, which made it quite awkward, honestly.

Shampoo is great
Shampoo is great. Nice smell and hair feels fuller after use.
Good price and was easy to order and fast delivery.
Packaging was a bit scarce inside the bigish box, but that's the only negative.

Very Satisfied
Ordering was easy, delivery by Evri wasn't the best so contacted Thix through their website. They responded in good time and offered a solution which was very well received by myself. Great customer service and would highly recommend. Just started using the product and all looking good so far, hair does actually feel thicker already.

Great product
Great product - smells good, hair feels clean & fresh when used.
Not keen on the metal bottle, makes using it in the shower a bit of a pain
Overall great product

Thanks for the kind review, glad to hear you think the product is great. 😊
We understand using aluminium bottle is bit different to plastic. We're on a mission to remove the mass of single-use plastic from our shower shelves. All our bottle packaging is made from recycled aluminium. It can be infinitely and widely recycled (unlike plastic), with 75% of all aluminium ever produced still in circulation today.
Best wishes, THIX Team. 💚
Thix shampoo is truly amazing
Thix shampoo is truly amazing, before Thix shampoo came into my life, my hair was coming out at a alarming amount, now when I shampoo and leave on for 3 mins, and there is only a small amount, I would highly recommend, especially for the over 50s.
