Reviews mention

  • Striking, instagrammable bottle design
  • Engaging, customizable quiz experience
  • Pleasant, long-lasting signature scents
  • Occasional effective detangling conditioner
  • Inconsistent, underwhelming formula performance
  • Overpowering, artificial fragrance options
  • Drying, low-slip curly conditioner
  • Residue buildup causing greasy roots

Function of Beauty earns polarized reviews: while customization, scents, and sleek packaging delight many, the formulas often perform like standard shampoos and can leave hair greasy, dry, or even shedding—so the brand is inconsistent rather than reliably good. Reviews also praise detangling conditioners and defined curls for some hair types, but cite overpowering/artificial fragrances, residue and build‑up, weak moisturization for textured hair, and faulty pumps or short straws as recurring drawbacks.

  • The package has not been sent yet or I have not received it yet. I would like to know if it is possible to figure out where is the package located? Thank you

  • I have difficult to manage hair. The shampoo and conditioner from Function of Beauty help control my issues! I also have healthier hair. I am thrilled with their products and the subscription service makes it so easy!

    Feedback

    It is worth giving them a chance for cleaner hair care products! Much better than anything I have tried from stores!

  • I ordered a package. A month later still nothing. The customer service say it going out but then radio silence

  • Absolutely love the products, wonderful hair care and body care. Great fragrance and overall good products.

    Feedback

    My only feed back is for hair care I only need this every 5 months very dry hair. Currently the subscription is every 2 months, I ended up with product overload. You cannot pause that I could see for more then 2 months.

  • Great customer service and my hair has never felt better. Even my hairdresser has noticed the difference in my hair since I switched. I now use hair care and body wash products from FoB and and thinking of subscribing to the face wash too since I have had such great results with their other products.

    The shipping can be a bit delayed. I keep my old bottles of shampoo/conditioner just in case I run out before my resupply gets to me.

  • I love smell of it and get clean and clear hair

    Feedback

    Excellent service from you to me the hole way

  • My hair feels and looks amazing and refreshed after only a few washes with the shampoo and conditioner made for my hair. The only issue is my scalp itches now.

  • I did not like their products. Packing is simple and nice, but the product itself did not work on me. Purple toner did not tone my hair and also didn't make my hair that soft either.

    Looking into your formula.

  • I absolutely love this product I love that I'm able to customize it I dye my hair purple with professional grade hair dye I also have psoriasis that is on my scalp using this product helps my psoriasis I can actually feel the tingling and it's in a good way plus I only have to wash my hair once every 5 days which is great for my hair dye I did an experiment on how long I could go between washes 14 days before I showed any kind of greasiness on my roots I probably could use some dry shampoo in one another two or three days but I didn't I washed my hair. I never use any type of product in my hair.

    At first I went back and forth on ordering because of the price but my 16 oz bottles lasted me 6 months with me making sure that I pumped the exact amount of product out of each bottle every time I wash my hair

  • The concept was cool, being that you could apply your own ingredients. I added hair growth but it just made my hair fall out so much. It was crazy.

    Feedback

    Work on your ingredients rather than your packaging

  • The packaging and the idea behind the product is lovely. The fact you can create your own formula sounds wonderful… However I am not sure how “customized” your formula actually is. I have created mine for dry hair, really just to nurture my hair because I never had any problems. Never in my life have I struggled with dandruff. Since I started using Function of beauty shampoo and conditioner I have experienced really dry scalp and dandruff, which makes me feel quite insecure about my hair right now! I’m highly disappointed in this product because it is not cheap and I expected more from it.

    Feedback

    Make higher quality products… the quality right now is worse than most drug store products

  • Got the curly base shampoo and conditioners from target & added booster shots. The smell was really good but yet again fragrance is drying, which I realized with my hair over time.

    Feedback

    Maybe less fragrance

  • I don’t usually bother to leave reviews but this product was SO bad , I had to. I chose an anti frizz option within my spec which left my hair visibly greasy within hours of use. I think I spent around £38 on a shampoo and conditioner and I’ve thrown it away after using it twice.

    Feedback

    The product is terible

  • I love Function of Beauty! After using this for the first time, my hair felt super soft and was really easy to brush. My hair has never felt healthier. I have had the shampoo and conditioner for almost a month now and I still am not halfway through the bottle and I have long hair! If I can make this last to December, I will be happy to buy more! I love the peach smell as well. It stays in my hair for a few days.

    Feedback

    Only thing that I recommend is please offer more smells! I don’t want to subscribe and feel like I’m missing out on a lot of other good smells :)

  • Don’t fall into the belief that customization and not being a store bought brand makes it a better product. I am someone who cares a whole lot about my hair. I don’t cut my hair at all which means my hair is long, thin, and damaged. It needs good product in order to have the best results. I thought I would have that with FOB but I’ve found that it is not as good as my other shampoo and conditioner (L’Oréal Elvive Dream Lengths). FOB has made my hair feel more brittle and I’ve noticed a lot more hair loss. I will definitely not be purchasing again. The scents and customizations aspects of it are nice, but it is not worth the cost or the results.❤️

  • It was a nice packaging and smell but my hair didnt feel any difference after using it.

    Feedback

    Quality

  • A while ago they sent me their cleanser, serum and moisturizer. I love how I was able to customise everything to fit my needs and wants!

    Feedback

    The products themselves were fantastic, I loved the packaging, everything was a lovely sensorial experience but I do think the price point is a bit steep.

  • Too much packaging. Wasn’t worth it. Would like if made in zero waste for such as a bar.

  • I really wanted to like this, but it was just OK. I have wavy hair that will curl into ringlets and frizz if it's super humid. I purchased the purple for wavy hair, with the curl definition, lengthen and strengthen add ins. I feel like it didn't do much for my hair, it didn't smooth it out or make my curls more defined. I loved the ability to really make it my own with the add ins, but it just didn't do what it said it would for my hair.

    Feedback

    I feel like some of the add ins, like color protection, should be in every bottle and not as an add in.

  • I tested tried this via purchase. It was okay. ‘Y hair didn’t feel particularly nice after using it. They did a reformulation and it still felt dry and straw-like. Wasn’t particularly impressed and had no desire to do another reformulation.

    Feedback

    No idea honestly.
