Function of Beauty Review: Is It Worth It?

Function of Beauty offers hair-conscious customers the opportunity to order fully customized shampoo and conditioner sets based on your hair’s texture and up to five needs. Plus, you can even customize the color and scent.

The idea of personalizing shampoo and conditioner that addresses multiple concerns was started by two MIT grads, Zahir Dossa and Joshua Maciejewski, as well as Cosmetic Chemist Hien Nguyen.

Zahir Dossa, co-founder and CEO, states that the idea for Function of Beauty was inspired by a lack of variety in the shampoo aisle. “Most products will cater to either a hair type or a specific goal,” says Dossa. “Very few cater to multiple goals.”

The company claims that, by using their hair profile, there are 12 billion possible combinations of formula components. Yours are decided using the information you provide, which is then processed within Function of Beauty’s proprietary algorithms to create a product set that’s as unique as your hair.

While Function of Beauty formulas promise to differ greatly depending on the personal information that you enter, everyone shares several things in common. Each shampoo and conditioner they create are:

  • Sulfate free
  • Cruelty free
  • Paraben free
  • Toxin free
  • Made in the USA

Interested in creating a custom shampoo and conditioner? Here’s how:

How to Customize Your Function of Beauty Shampoo and Conditioner

The idea of shampoo and conditioner that’s tailored to suit your hair’s needs is certainly interesting. But, how does it work?

Not to worry—Function of Beauty doesn’t have you researching chemical compounds. Instead, the customization process starts by filling out a hair profile.

Step #1: The first steps include selecting between the following:

  1. Your hair type, from straight, wavy, curly, coily.
  2. Your hair structure, from fine, medium, coarse.
  3. Your scalp moisture, from dry, normal, oily.

Step #2: Function of Beauty asks that you pick five hair goals out of the following: deep condition, replenish hair, fix split ends, strengthen, hydrate, lengthen, volumize, color protection, thermal protection, anti-aging, anti-frizz, curl definition, shine, straighten, nourish roots, soothe scalp, and oil control.

Step #3: Here, you can customize the look and smell of your formulas. Select separate shades for your shampoo and conditioner, choosing between blue, pink, orange, teal, and purple.

Then, choose a fragrance (both shampoo and conditioner will have the same scent), between cucumber mint, grapefruit hibiscus, sandalwood violet, and a minty blend of essential oils.

You can also select your fragrance strength, then choose which name is displayed on the bottles.

How Much Do Function of Beauty Custom Shampoo and Conditioner Cost?

In the final step, you select which size bottles you’d like to order. It’s here that Function of Beauty offers a rarely seen convenience: You can choose mismatched size shampoo and conditioner bottles, which is wonderful for anyone who always goes through the two products at a different pace.

Here’s the rundown on sizes and costs:

  • 8 oz Shampoo & 8 oz Conditioner: $32
  • 16 oz Shampoo & 16 oz Conditioner: $42
  • 8 oz Shampoo & 16 oz Conditioner: $38
  • 16 oz Shampoo & 8 oz Conditioner: $38
  • 16 oz Shampoo: $26
  • 16 oz Conditioner: $26

Every Function of Beauty order offers free shipping and free returns. The only other variable is state tax, which applies to NY and PA residents only.

However, note that there’s a difference between “free returns” and “money back”—the free returns alludes to Function of Beauty’s happy hair guarantee, which states:

“We believe in your happiness and satisfaction above anything else. If you’re not completely satisfied with your set, we’ll reformulate it so that it’s as perfect as you.”

It’s important to understand the parameters of Function of Beauty’s satisfaction guarantee: You can return your shampoo and conditioner for any reason and receive a reformulation. However, you’re not able to return the product for a refund.

What Customers Are Saying About Function of Beauty

To find out whether Function of Beauty products were perceived as perfectly tailored by customers, we headed to Google and the company’s Facebook page in search of reviews.

A review at The Most Happy states that she was thrilled with the oil control offered by her custom shampoo and conditioner, and that it allowed her to go up to 3 three days in between washes.

Hello Giggles reported an overwhelmingly positive review along with a nice touch: That Function of Beauty’s packaging “includes a print-out of your hair profile and a recommended personalized hair care regimen to ensure the products are as effective as possible (for example, some people may benefit most from daily shampooing, while others might benefit from way less).”

Awareness of Function of Beauty has recently exploded, which has meant a mass of orders—and a few customers say that their shipments have been later than expected.

However, reviews also mention that the company notified each customer with a personal email from the CEO, as well as issued credits for late delivery.

Even despite the late deliveries, reviewers on Function of Beauty’s Facebook page state that they couldn’t be happier with their products—or the company’s customer service.

Some Final Thoughts Regarding Function of Beauty

Overall, reviews of the actual products are positive, with multiple reviews commenting that the formulations addressed not just one, but their own specific combination of hair woes.

For example, one reviewer with oily-but-damaged hair said that her dry ends looked and felt incredibly soft, but the top, more the oil-prone section didn’t appear greasy or weighed-down.

While overall reviews of Function of Beauty are positive, my experience writing about cosmetics and beauty products for HighYa left me with a few concerns:

For example, while filling out the hair profile I noticed that some questions, such as hair type, are pretty straightforward. However, others, such as your scalp moisture, are less so, since my research shows that your scalp can become more oily if your shampoo is too drying, or if you’ve recently started using hot tools.

The risk of user error isn’t huge—consumers buy their own shampoos and conditioners all the time. However, with the mindset of hoping to get the most value out of ordering custom shampoo and conditioner, I was left wanting for more detailed descriptions to help make my selections.

So, I was relieved to come across one review that stated it the customer had a positive experience reaching out to Function of Beauty with questions about how to select options that were best for them.

Bottom Line: Function of Beauty Appears to Aim for High Customer Satisfaction

Considering the overwhelmingly positive reviews and reports of attentive customer service, we think it’s safe to say that consumers who are interested in customizing their hair products might be very pleased with this brand.

However, we think it’s important not to shoot from the hip when it comes to selecting your hair type and goals—to really get a good value (and experience), don’t hesitate to reach out and ask.

Speaking of cost, while the price definitely isn’t cheap when compared to your typical drugstore brand shampoo (these shampoo and conditioner sets go for about $40), it’s absolutely comparable to other luxury and salon-level brands—plus, shipping is free.

Another perk of Function of Beauty customized products is that you can tweak your formula based on the season, if strands have been subjected to a new chemical process, or received a dramatic cut.

Bottom line: If you decide to shop this brand, reviews lead us to believe that you’ll be pleased with the results.

Just don’t rest on your laurels and stick to the same formula! Instead, commit to getting every last drop of value out of each order by asking questions and tweaking your formula to fit your hair’s changing needs.

    I feel conned

    • Brisbane, Queensland, Australia,
    • Jul 11, 2019
    • Verified Reviewer

    An ad for this company popped up on my Instagram feed and I contemplated whether or not to get this for two whole months, I watched YouTube reviews and they all raved about how great it is, but when I finally ordered mine it was nothing as amazing as everyone raves.

    For one of my hair goals, I chose anti-frizz because it's always a problem I have with my curly waves, yet the only thing this product seems to be doing is making my hair frizzier as well as drier. Adding other products like leave-in condition only makes the frizz worse.

    Sure, the custom colors and scents are great and it's aesthetically pleasing but it's like any other cheap formula shampoo and conditioner only more expensive.

    Bottom Line: No, I would not recommend this to a friend

    Function of Beauty, my results from this product

    • Dallas, TX,
    • Jun 26, 2019
    • Verified Reviewer

    I started using this product back in February 2019. I love the colors, the scent, the consistency and how you can take the quiz and it's tailored to your results BUT...I noticed a few weeks ago my hair has been falling out. I have super long hair and very thick hair and my stylist even noticed. She said, "What are you doing differently?" This is what's changed. I changed hair products. I read some other reviews and I'm not the only one this is happening to. I should have requested the ingredients but I didn't so I quit using it. My scalp was even getting itchy every time I used it. It's taken me a good month to get my hair back to normal but I'm sad that this has happened and wish they would change their ingredients but for now I'm going back to my old products.

    Thought I was great, until a few washes later.

    • Queensland, Australia,
    • May 30, 2019

    I honestly will say that the first couple of washes felt and smelt sooo good! But after a while I noticed my hair drying out and becoming more damaged each time and my scalp became so itchy and flakey! And not just like a bit of dandruff, it was embarrassing, and made my hair so hard to brush through as well. I seriously went and cut off most of my hair because I felt my hair was getting that bad. I wouldn't recommend using it on colored hair either as I found my hair color was literally washing out every time. You have to use a lot to really wash all your hair properly. I went back to my regular shampoo and my hair instantly felt so much better and fresh.

    Smells great...but lost like half my hair

    • Massachusetts,
    • Apr 25, 2019
    • Verified Reviewer

    I wish I researched better...I selected "oily scalp" and like many reviews, I'm now coming across my hair has been falling out by the handful. Never again. Yes, it smells delicious, and my name's on the bottle, but the pros end there. I know we all shed hair naturally, but this is literally in clumps every time I touch my hair. I'm devastated. It took me about 1/3 of the bottle used before figuring this out...but shame on Function of Beauty who call themselves scientists saying they can formulate the perfect shampoo...nothing perfect about this. You couldn't pay me to continue using their products.

    No chemicals, then why did my product smell like chemicals?

    • Georgia,
    • Apr 6, 2019
    • Verified Reviewer

    I got this to try and when I opened the bottle the first time it smelled a little chemically, but I was like ok, I will still give it a try. The first and only time I used it I washed my hair and the shampoo smelled a bit chemically, not at all like pear. The conditioner on the other hand, as soon as I put it in my hair, it smelled like pure nail polish remover. I have never rinsed my hair out so fast in my life. After using it my hair actually felt really dry. Maybe they made a bad batch for me, but I wouldn't risk it again! Funny thing also, when looking back at my emails, not a single one of them has an order number, just pictures of what I ordered and the date!

    Customer service has improved! Refunds aren't a hassle.

    • Oregon,
    • Mar 28, 2019
    • Verified Reviewer

    I have wavy hair that needs a lot of hydration. Even though I chose "deep condition," "hydrate," and "anti-frizz," my hair was dry and frizzy even after TWO applications of conditioner. Needless to say, the product didn't work for me.

    The company has a 30-day money back guarantee, but I was really nervous after reading other reviews on here. No need! Customer service was great. They will still offer you a reformulation, but as long as you DO NOT ACCEPT it and it's within 30 days, they will refund you the purchase price.

    Good to know that you can get a refund if it doesn't work out for you!

    Likely scam

    Their product doesn't make any difference and they are really expensive. Just a word of caution - they have a NO RETURN POLICY, even for unopened products.

    Their site hosts their review so not trustworthy at all.

    Great shampoo and conditioner!

    I wanted a shampoo + conditioner that's cruelty-free, good for dandruff, and good for oily hair. I decided to try out this company and it's great!

    I was able to customize the formula, color, scent, scent strength, etc. Even included a sticker pack. I don't have any complaints.

    Not worth the money

    • Orange County, CA,
    • Mar 11, 2019
    • Verified Reviewer

    I am all about spending money on a hair product that works great and I love. So, I figured I would try this. This product completely dried out my hair and left it damaged. I know my hair really well and I am confident that I chose the right formula that they were asking. Great scent and it was nice knowing it was pure; However, the damage was not worth the money. It is definitely noticeable if a shampoo and conditioner are working with your hair, and this definitely did not work for mine. My sister also feels the same way. Almost got to the halfway point if our separate bottles and had to throw them out. Don’t get it and don’t listen to the people who do it for an ad so they get money!

    Amazing!

    • Canandaigua, NY,

    I've always struggled with an oily scalp, but dry, split ends and frizzy hair. I tried so many different products from cheap drugstore brands to expensive salon products and none resolved all of my hair problems. I am so glad that I finally tried Function of Beauty and will never go back to any other brand! My scalp isn't oily anymore and I can easily go 3-4 days between washes. My hair is so soft and easy to manage and the ends aren't dry and straw-like anymore. I have long, thick hair and have always used more conditioner than shampoo, so I order the 8 oz shampoo and 16 oz conditioner and they last about 3 months. It's a very concentrated product, so you don't have to use a lot. I prefer dye free, so I can't comment on the colors, but I LOVE the scents - I've tried Peach and Pineapple so far and they are both wonderful!

    Function of Beauty has changed my life! My hair has always been damaged due to bleaching but not anymore. My hair has never felt or looked better. I love the sents and I love that you get to customize everything! Also, if it doesn’t work for you, return it within 30 days and they will reformulate it for you! I absolutely love Function of Beauty.
