Sub cancelled after 6 years
I had been a long time customer, around 6 years. I loved the customisation of the shampoo/conditioner and since I only wash my hair once or twice a week the product lasted for some time. Then the price increase happened- I stayed with them because I liked the product but my recent order has had me finally cancel my subscription. Not only was the order almost a month delayed, it took an additional 2.5 weeks to arrive. The bottles have gone down in size by 148mls/5oz which is quite substantial when the price point is still $100. I cannot justify the price anymore.

I have been using my formula for years…
I have been using my formula for years now and did a reorder on 4/28/26. It didn't ship until 5/20 and here it is 5/25 and it won't be delivered until tomorrow. Ridiculous! 0 stars for promptness and 5 for product which averaged to mt 3 star review.

Utter customer service FAIL
I'm giving two stars because I've been a loyal customer for years and have really loved the products. But my recent experience has been a complete failure and the customer service team has not done anything to rectify it.
My subscription was set to renew on 4/15. I received an email notification my order had shipped, and my card was charged in full. I checked my account on 5/1 since I had not received the order and the tracking link didn't work so I contacted them asking them to check on the order. They replied on 5/3 saying my order never actually shipped and was delayed due to "increased demand." They gave applied a 20% discount on my account for the next order.
I replied to them on 5/6 asking why my card was charged and I received shipment notification if it never shipped. The order was displaying as fulfilled on their website. I asked them to send my order with expedited shipping to make the situation right. They replied the next day saying my replacement order had been shipped and provided the tracking information but said nothing about my request to expedite it. I replied the same day to ask if they expedited the shipping. They replied the next day, completely ignored my question about expedited shipping and gave me a 20% refund on my order as an apology.
I replied again on 5/11 because the tracking link they provided was not updated with a delivery date. By this time my order was basically a month late and I was out of shampoo and conditioner. I asked to speak with a manager about the situation and asked why they didn't expedite the shipment like I had requested. They replied with a 50% refund on my order but ignored my request to speak with someone else and continued to ignore my question about expedited shipping.
I responded again, and thanked them for the refund, however, I explained that the refund doesn't make shampoo show up in my mailbox. I don't need the money back, I need the product I paid for. I asked why content of my emails was being completely ignored. That email, and the subsequent email I sent two days later was also completely ignored. They stopped responding to me.
And by the way, I STILL DON'T HAVE MY ORDER.

Product is expensive, customer service questionable.
I didn't receive the email confirming my order was upcoming so I could change the date. My credit card was charged, and within 12 hours I emailed FoB to stop this order and refund the money. There is no possible way my order had gone into production and it could have been delayed, reasonable customer service would have accommodated that. I was told "too bad, so sad" - no confidence FoB has the desire to "make it right".
I ordered a personalized shampoo and conditioner based on my hair profile. The checkout was simple, with questions about hair type and goals that helped tailor the formula. Delivery was quick, and the results are noticeable: my hair feels healthier and my scalp less itchy. Quality product, and my partner now wants her own custom set too 😊

Look somewhere else
First off, there is no phone number for you to contact the company. So if you have a request, you can wait 3-4 business days until they reply to your email. My last order was "created" 19 days prior to it shipping and then they told me that they can't cancel it because it was already processing. I was with them for quite a few years and I finally had enough. I had also signed my 2 daughters up. My one daughter's hair got so greasy after using their shampoo and conditioner that we're sill struggling with this issue months later. Needless to say, I will not be purchasing from them again.

Customization is interesting
Customization is interesting, but results were not exactly what I expected.

Illegally Used My Credit Card
This review is not about the product itself which is just good, but it is about their illegal & unethical business practices. I was a faithful customer for at least 7 years, but when I wanted to cancel my subscription I sensed it would be a problem & I was right. So, I thought that the easy way to do it would be to just wait for the credit card they were using to expire & inform them I was canceling then. It seemed to work, but then six to twelve months later, they Illegally started using my credit card number again & sending me product. It was a HUGE hassle getting charges reversed & getting them to stop this. They would not admit they had done anything wrong. I DO NOT recommend getting involved with this company.
I used to use FoB religiously about ~4 years ago. Since then, every new order would have smaller bottles for higher prices. I cancelled my subscription long ago but kept a secondary one for my MIL. Now I've been charged FOR A THIRD TIME for my MILs subscription, even though I cancelled it 3 times already. This company is genuinely predatory. I used to pay 60 $ for a shampoo + conditioner that would last nearly 6 months, now I got charged 100 $ for a 11oz shampoo + conditioner. The last uncancellable subscription shipment before that cost 80 $, with the 20 $ price hike being neither announced or warranted.
Received NO warning before my subscription renewed after a 6 month break, emailed immediately after I was told my order had been placed (with a price increase I was unaware of) and then radio silence from the team until my order was already in the factory meaning nothing could be done. The formula was wrong and now I have lost $70! Horrendous customer support.
I have been a customer for 4 years, but sadly today they have lost my loyalty!
I love the products, I am a customer since 2021 and my hair never felt better, however, the price just keeps growing and growing to the point where it is no longer worth it. Website has a lot of bugs, cannot change sizes myself, cannot add phone number to delivery details (I mean I can but it does not stay there), thus always missing my delivery, and when got in touch with CS (especially via email), felt no care to my issues at all. The company was so much better at the beginning, used to praise it to all my friends, I truly hope they will improve.
So so disappointed in this company. I made a purchase in Nov 2024, an automatic subscription charged me 40.00 more from the last purchase for the same products. I email them on the day I receive an email noticing they have taken 160.00 from my account, to change the order as I have now got colour in my hair so thought to change the type. Not allowed to make any changes to orders, what a rip off. Too expensive, terrible customer service, all automatated, please be warned they just dont care.

Overpriced! Not worth the money
I was a longtime user but they’ve gotten so much more expensive and that with smaller packaging then before! So less for more. I like the product but it’s overpriced and not much better then much cheaper brands. Also, when you skip your order they still charge you and send it like it never happened. Also I had a product that wasn’t working how is should be, and I had to fix it myself. So there’s not much service for how expensive it is. I would avoid and try alternative brands!

Avoid
Like many other people here, my subscription was reactivated after cancelling. When I reached out, I was told it was essentially my fault and that they weren’t going to cancel my order.
The products smell lovely but they gave me dandruff despite never having it before. I even reformulated my products so that they addressed dandruff and they made it even worse.
They don't cancel subsciptions. Password for account will no longer work and they dont do password resets to cancel subscription. Finally charging back with credit card.

They reactivate cancelled subscriptions and charge your account
I have been a customer for over three years. I received a shipment notification for an upcoming shipment and logged in to canceled my subscription. That was likely three months ago. I just received a shipment notification. I chatted with their customer service to dispute, and conveniently they have no record of my prior cancellation, and "due to the nature of the product it's non-refundable." She then gave me my tracking information! I googled this issue, and apparently I am not the only one they have done this to.
when i first got my shampoo it was amazing my hair is soo nice… but now they are charging double amount and giving less product and even if u subscribe they still charge £20 for delivery and its just extra money for nothing… sadly am leaving function of beauty bcus its not the same as it was 3 years ago… even the app is strange now so bye bye from me cus every thing about them is bad and they dont even help any more.. thts all
I asked to cancel my order right as it was placed (automatic order) and was denied because it was already processing. Not sure how it can process within minutes… anyways, after being a loyal customer for over 6 years, I would have expected a better customer service response but the interaction was so mediocre and poor. I have subsequently cancelled my subscription entirely.
