How does it work?

Function of Beauty is the world’s first fully customizable hair care brand that allows you to create shampoos, conditioners, and styling products based on your individual hair type, hair goals, and aesthetic preferences (including color + fragrance). Founded by a dream team of world-class MIT engineers, cosmetic scientists, and developers, each product is individually formulated using the latest science and technology to help ensure that your formula is every bit as unique as you. We cater to all textures of hair, from straight to wavy, curly to coily, and formulate without sulfates and parabens to ensure that customers of all ethnicities and hair types can create a formula that fits their unique hair needs!

How do I complete the hair quiz?

How do I select my hair type?

    We define the different categories of hair type as:

  • Straight: Hair strands tend to not have a bend or a curl. Hair Type 1.
  • Wavy: Hair has a slight bend or wave pattern; somewhere between straight and curly. Hair Type 2.
  • Curly: Hair has a definite curl, S-shaped, or loopy pattern. Can be prone to dryness and frizz. Hair Type 3.
  • Coily: Hair has a tight curl, spiral, or zig-zag pattern; tighter curls than curly hair. Sometimes known as "kinky" or "textured" hair. Hair Type 4.

How do I select my hair structure?

    Hair structure doesn’t refer to the number of hair strands you have, but rather the thickness of each individual strand.

  • Fine: A single strand is thinner than a sewing thread. If you take a strand of hair between your fingers you don't feel anything.
  • Medium: A single strand is about the thickness of a sewing thread. If you take a strand of hair between your fingers you can feel the hair.
  • Coarse: A single strand is thicker than a sewing thread. If you take a strand of hair between your fingers you can feel a strong, thick strand.

How do I select my scalp moisture?

    This is the level of moisture/oil on your scalp:

  • Dry: Your scalp might be dry or flaky. You typically wash every 3-4+ days.
  • Normal: Your scalp is about the same a day after you wash it.
  • Oily: You feel the need to wash your hair daily.

What are the fragrances like?

    Fragrances can definitely be subjective, but we like to think we have something for everyone.

    Signature fragrances:

  • nude (p)each: Top Notes: Peach nectar, mandarin, lemon zest, jasmine.
    Reminds us of: Cutting up fresh, juicy peaches on a hot summer day.
  • (pear)fection: Top Notes: Pear, apple, sweet musk, subtle florals.
    Reminds us of: Biting into a juicy pear on a crisp fall day.
  • all (you)calyptus: Top Notes: Eucalyptus, mint, lavender, rosemary.
    Reminds us of: An exhilarating hike through the misty mountain tops.
  • fragrance free: A great option for those with sensitivities.

    • Limited edition fragrances (but always available to our subscribers!):

  • strike a (r)ose: Top Notes: Rose, black currant, sandalwood, orange blossom.
    Reminds us of: A cool, modern rose fragrance with a bit of edge.
  • milk(shea)ke: Top Notes: Shea butter, vanilla.
    Reminds us of: Indulging in a rich, creamy dessert.
  • cherry bl(awesome): Top Notes: Cherry blossoms, jasmine, amber, lilies.
    Reminds us of: A romantic springtime stroll at peak bloom.
  • naughty or (sp)ice: Top Notes: Cardamom, nutmeg, vanilla bean, cinnamon.
    Reminds us of: Biting into a freshly baked holiday cookie.

How do I choose my hair goals?

  • Strengthen: Increase your hair's natural resilience and elasticity, stimulate healthy hair, and help protect your hair from future breakage.
  • Anti-Frizz: Nourish and soften the hair texture for a smoother appearance, while also protecting strands from added frizz, static, and breakage.

  • Fix Split-Ends: Smooth, coat, and seal your split ends to create a sleek finish while also helping to prevent new split ends from forming.
  • Hydrate: Restore your hair's natural moisture balance, prevent future moisture loss, and help treat damage with an added dose of long-lasting hydration that won't weigh your hair down.
  • Replenish Hair: Replenish nutrient-depleted strands, reverse damage, and help protect your hair from environmental stressors with a unique blend of high-quality hair ingredients.

Do you test on animals? Do the products contain parabens or sulfates? Are your products gluten-free?

No, no and yes!

As a company, we are committed to creating products that use only safe, natural ingredients, wherever possible, and are continuously seeking new and environmentally-friendly ingredients. All of our products are free of sulfates, parabens, mineral oils, phthalates, and gluten, among many other ingredients. Our products are also 100% vegan and cruelty-free!

Do your products contain silicones?

Yes, our products do contain silicones—the majority of which are predominantly water-soluble to help prevent the likelihood of product build-up and loss of hair volume. We do, however, also give you the option to make your shampoo and conditioner formula silicone-free, as we realize that silicones may not be right for everyone.

For formulas that do contain silicone, we use only high-quality, water-soluble silicone that won’t leave a residue on your scalp or hair. We use silicones because they are serious conditioning multitaskers that can help with hair softness, smoothness, and detangling. If you haven't tried a silicone-free product before, it may take a few weeks/washes for your hair to adapt. You can select a silicone-free shampoo and conditioner formula by selecting the "silicone-free" option on the #hairgoals page of the hair quiz.

What are the boxes made out of?

Our kraft boxes are 100% recyclable, and made with at least 30% post-consumer recycled materials. The materials are also sourced from environmentally responsible paper suppliers and are certified by the Sustainable Forestry Initiative.

Are your products safe to use during pregnancy?

First off, congratulations! And yes, our products are all safe to use during pregnancy. If you have any specific concerns though, we always recommend checking with your physician first.

Do all orders come with pumps?

All orders come with pumps! They arrive loose and disassembled in the box. You can also decline to receive a new set of pumps on your order confirmation page. Feel free to use the pumps you have for as long as you’d like (Mother Nature will thank you.)

What are your bottles and caps made of?

Our bottles are all made of 100% recyclable PETE-grade plastic. Our caps are all made from 100% aluminum, which means, like our bottles, they’re now also 100% recyclable!

What if I’m allergic to a specific ingredient?

If there are certain ingredients that you are allergic to or wary of, you can feel free to reach out to us here for more information. We also always recommend consulting your physician first if you have any concerns.

What is your stance on controversial ingredients?

Your safety and well-being are always our top priority. Our formulations avoid potentially harmful or toxic ingredients such as sulfates (including SLS & SLES), parabens, phthalates, triclosan, mineral oils, formaldehyde, among many others (please see below for a more detailed list). We do not formulate with ingredients banned in the EU.

Are your products safe to use on children?

All of our products are formulated to be safe; however, children may have unknown allergies and may be more sensitive to specific ingredients than adults, which is why we always recommend consulting a physician first if you have any concerns.
