Very bad customer service. Inconsistent number of bottles provided. Leakages. Overpriced. Can't get through to anybody on the phone. Not sure if the product has been working. I hope it has been.

Genuinely a great service from the support team and an amazing product which actually works.

The hair regrowth serum has helped regrow my hair much faster after my hair transplant. I got recommended this product by my hair transplant surgeon and I’m glad I listened to him

Supply issues no contact

Paid for 6 month supply - 6 bottles, but only one bottle arrived with a note detailing supply issues. Stated the rest of my order would arrive in the coming weeks.. 4 weeks later the rest of my order arrived. Their website says next day delivery but it’s not, their customer service didn’t reply to 2 emails chasing my order, and for the price - I’d look at their competitors. Poor customer service/ general service, I won’t be ordering again from them.

Last year the company was brilliant

Last year the company was brilliant. They gave me so much bottles this year the company was awful. They sent me 12 bottles which is not gonna last me up to a year. I requested to have 15 more bottles. Their manager refused and said no I paid £387 out of my account which they took out. It was an embarrassment and the manager was shameful. I would not use this company. They did it to themselves.

Best and quickest customer service

It's so easy to deal with twenty-one again.

Their customer service is simply the best. They always respond and act quickly.

I had a delivery issue with Royal mail. Customer service was straight on it and kept me updated every step of the way.

I cannot recommend this company enough.

Amazing products

Amazing products, couldn’t recommend a company enough.
I have suffered no side effects yet noticed a definite improvement in my hair, I’ve used other products from different companies and had issues with most but these products have changed everything

Hair Loss Treatment

Hair Loss Treatment. Made My Hair Worse and Customer Service Ghosted Me I’ve been struggling with thinning hair for years, so when I saw TwentyOneAgain’s hair loss serum advertised as clinically proven and better than minoxidil I was hopeful. At £85 for a small bottle, it’s pricey, but I figured it might be worth it if it actually worked. The first red flag was the packaging—the bottle arrived leaking, and about a quarter of the product had spilled out. I contacted support, and they apologized and sent a replacement (which also leaked, but less badly) I applied it as directed for two months, and not only did I not see any regrowth, but my hair actually started falling out more. I panicked and stopped using it, but the excessive shedding continued for weeks. I sent photos and a detailed email to their support team, and after one vague reply hair shedding can be part of the process they completely ghosted me. No follow-up, no refund, nothing. I’ve since switched to a cheaper, pharmacy-brand minoxidil, and my hair is finally stabilizing. This product is a complete rip-off, and their customer service is a joke.

Pricing Misrepresentation: The reviewer claims our hair loss serum costs £85, which does not correspond to our actual product pricing displayed on our website. This represents another factual error that misleads potential customers.

No Customer Found: Comprehensive searches of our customer database, shipping records, and customer service logs reveal no record of this customer, the described orders, or any reported packaging issues and customer service interactions.

Product Claims: The specific product attributes and marketing claims mentioned in this review do not align with our actual product descriptions or marketing materials, suggesting fabricated details.

Missing Customer Communication: We have attempted to reach out to this reviewer to verify their experience and offer resolution, but have received no response despite multiple contact attempts.
Pattern of Sabotage: This review appears to be part of a systematic campaign by competitors to damage our reputation through false reviews, representing an unethical business practise that harms both our company and customer trust.

Legal Action for Defamation: Given the demonstrably false information and defamatory nature of this review, we are pursuing legal action and will hold those responsible accountable through the courts.

We encourage anyone with genuine concerns to contact us directly, and urge customers to verify product information and pricing through our official website rather than relying on unverified reviews.

Was recommended the hair lotions from a friend. As I had slight thinning and as a girl it was worrying me.

But within 2 months of using the lotion my hair has become thicker and has gotten its volume back. Will definitely recommend.

No order received despite £368 taken from credit card. Find somewhere else as it looks like I'll have the pain of the chargeback process via the credit card 🥴

Updated review. Support did respond based on the review... Suddenly it's dispatched and suddenly it can't be refunded. Should have just acknowledged the order instead of sitting on it. One star changed to 3

Inadequate packaging and all wet through, leaking inside the bag. Worst experience and support too slow at responding. I am definitely in touch with credit card company. All loose bottles in a thin jiffy bag. No wonder bottles have been squished and leaked.
