Review summary

Created with AI, based on recent reviews

Evaluating 1,494 reviews, reviewers overwhelmingly had a great experience with this company. Customers frequently praise the products for significantly improving hair health, making it feel softer, thicker, and shinier, often alleviating scalp issues, and appreciate their natural ingredients and pleasant scents. Many also highlight the effective skincare range and consistently excellent customer service, noting quick issue resolution and a professional, caring approach. However, some customers noted that the products did not suit their hair, leading to dryness, thinning, or a tangled, straw-like texture, and a few also cited issues with thick conditioner consistency or non-functional pump dispensers. Additionally, a small portion of people experienced receiving orders with dented or leaking bottles upon arrival.

Amazing for bleached, fine curls! Highly recommend!

​I was searching for a good shampoo and conditioner set that could tone down the brassy, yellow tones in my bleached hair without causing any damage. I have a lot of hair, but it is very fine, naturally curly, prone to frizz, and easily damaged from bleaching, so I have to be incredibly careful with the products I choose.
​I discovered this brand on Instagram, and after checking the ingredients, I was thrilled to see that they use almost exclusively natural ingredients. Between the clean formula, the great reviews, and a nice promotion, I decided to give it a try.
​After just the first use, I am extremely satisfied! My hair feels in much better condition - it is smooth, lightweight, and flows beautifully. Even better, today is the third day after washing, and my hair still looks completely fresh! I know a true opinion is formed long-term, so I will update this review after a few more uses, but my initial impression is absolutely amazing. Highly recommend!

Thank you for such a thoughtful review, Bozena 💜 We’re delighted the Purple range has toned your bleached curls without weighing them down or drying them out. Fresh-looking hair on day three is a lovely bonus too.

I’m loving my new shampoo and…


I’m loving my new shampoo and conditioner. It took me a while to get used to the fact the shampoo doesn’t froth up too much but I like this fact as it rinses out easily. The conditioner is sublime…I just love it…I massage it in and then run my fingers through it (no combs or brushes for me!). I have tried so many different curly hair products in the past but Cornish Seaweed is my absolute favourite as it defines my naturally curly hair - thank you 🙏🏽

best purple shampoo ive tried

Having used many market brands to reduce the brassiness in my blonde hair, many of which left my hair feeling like straw and in need of deep conditioning afterwards, I was recommended The Cornish Seaweed Company, and I absolutely love their product. Not only does it smell amazing and use natural ingredients, but it also eliminates brassiness without stripping my hair of moisture. I would 100% recommend it and will continue to buy from them.

Doesn’t live up to the claims.

On the surface the instagram advert, ethos and packaging are good. I bought into the menopause support narrative and natural product. However I could not be more disappointed in a range of products. I have no issue with the order process or packaging. I do have an issue with products that despite their claims does not deliver. I tried for weeks now - and thoroughly disappointed in their performance. It is difficult to see where you are applying the shampoo (including the detox one) the consistency is light and breaks down too quickly to know where it’s been applied. I tried them in the shower and basin to see if I could get better results. The conditioner is a better product. Overall, menopause is a difficult enough journey particularly with your hair \ confidence to endure increase shedding, waxy finish and ultimately feeling your hair is still dirty. I really wanted this to work as I liked the messaging and branding (albeit at a higher price point). I have now reverted by to my prior routine now to try and reduce the shedding and get confidence back in my hair routine.

Incredible products

Incredible products. I bought the purple shampoo and conditioner and received a detox shampoo free. I used the detox shampoo first then followed with the purple products. The smell is beautiful and natural from all the products and my hair has never felt so clean. I will definitely be reordering all of these quality products, well worth the expense.

The BEST purple hair care range

The BEST purple hair care range
I was a little sceptical having tried countless purple hair care products. I also wasn’t expecting results straight away, having read natural products can take a few weeks to take effect. However from wash one I was delighted!! Finally a product that didn’t dull down my blonde, or give it a weird purple haze! Added to this I love the smell (spa fresh) and I love how soft and shiny it leaves my hair. All from a completely natural product range too. I would highly recommend this range 🤩

Great products


Great products. Delighted with the shampoo and conditioner. Expensive but you only need to use a small amount. I couldn't be happier with the results. My hair is soft, shiny and a lovely shade of blonde no sign of any brassy tones. Customer service was good. Products arrived swiftly, well packed. Smart designed containers. I will definitely continue to use these products. Thank you.

Lovely products, great customer service

I bought a 3 for 2 sets offer which included free products too. The smell is amazing, clears my head, refreshing and clean. Shampoo/ conditioner leaves my hair soft and feeling healthier,didn't realise how much better until I used another well known very expensive brand while away and I could feel the difference in how bad my hair felt in comparison. I also accidentally ordered an unscented soap, they sent me the one I'd wanted free, even though my own fault!
