What is Function of Beauty?

Published on: Feb 9, 2017

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

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 includes 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 & 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.

    Hair started falling out

    I bought this for my daughter, personalized for her thick head of hair. Although at first, she did like the way it made her hair feel (but it did not control the frizz as she had hoped). Within a few weeks, her hair was falling out in clumps.

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

    Love! I've only used it once, and I can see a difference in my hair! I dye my hair blonde every three months when I usually have dark black hair. Using this product made my hair feel alive again. The only downside is that the bottles are kind of expensive.

    Bottom Line: Yes, I would recommend this to a friend
