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!

3 guiding principles keep us honest:

1. We have a really long checklist.
All of our formulations follow the European Union regulations on safe cosmetics, (which bans nearly 1400 ingredients, vs only 11 by the FDA). We’re constantly checking up to ensure our ingredients are in full compliance with the strictest standards.

On top of that, we thoroughly check every new ingredient against 26 checklist items by 3 different departments. This screens for specific environmental and health hazards. The ingredients that make the cut are then reviewed in formulation with one another to make sure they’re safe when combined, and to safeguard the long-term health of our team in the factory.
2. We’re picky about our ingredients.
We're passionate about only using ingredients that actually help you achieve your hair goals and deliver performance without compromising safety. That’s why we use a combination of both natural and lab-made ingredients in our formulations – we know what’s natural is not always the safest or the best-performing, and what’s lab-made is not always bad or toxic.

No matter how you customize, it's all clean:
• Colors: all of our colors are both FDA and EU-approved for cosmetics. Plus, you can go dye-free
• Fragrances: our expertly-blended fragrances evoke sensorial experiences while sticking to our strict ingredient list. We also offer 100% natural fragrances blended from essential oils, and fragrance-free options
• Silicones: silicones are conditioning workhorses and have a long track record of safety, but we do offer silicone-free options for those who prefer it
3. We don’t compromise on our values.
Our ingredients are always vegan and cruelty-free. We strive to be responsibly sourced in as many of our ingredients as possible, and are always raising the bar in this area.

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!

Yes, our products do contain silicones— we’re a fan of them for a few reasons. For hair, silicone helps to create that silky, smooth feeling post-use. On skin, silicone acts as a barrier— letting moisture in but blocking particles like pollutants from entering. In both cases, silicone is unlikely to cause an allergic reaction, is vegan, and is known not to clog pores. For anyone who’s not a fan, though, we give the option to go silicone-free for most formulas. You can’t go wrong!

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.

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.)

If you head over to your account page, you can update your account info, shipping address, payment info, and see your order history. From there you can reorder your formula or make adjustments to a past order. You can also manage your subscription and find your referral link (with an easy to fill out form to send to your friends so they’ll receive a discount on their first purchase. You'll also receive the same amount in credit if they place an order using your link!)

As a Function Plus member, you can get ongoing deliveries of your favorite personalized formulas on the delivery schedule of your choice (every month, 2, 3 or 6 months). It’s easy to make changes to your formula’s hair goals, colors, or fragrances within your account. You also get exclusive perks (think free shipping, access to exclusive and past limited-edition colors + fragrances, invitations to help test-drive new products, and more!).

A few days before your subscription order is set to be filled, you will receive an email reminder to adjust your formula, change your delivery date, update your account details (like your address or billing info), and make any other edits to your subscription. You will be charged for your subscription when we start working on your new order.

Please note that since all formulas are fully customized, we cannot accept returns or apply refunds after your order has been processed. Any adjustments or cancellations made to your subscription after a payment has been made will not change your current subscription order and will instead be applied to the following subscription order.

You can modify your subscription plan from your account page. Under "Your Subscriptions", select "Manage" on the subscription you’d like to modify, and you’ll find the option to edit your formulation, edit the sizes of your bottles and frequency of shipments, adjust your billing information and shipping address, add or remove pumps, and choose fun add-ons like our customized leave-in treatment!

There’s also an option to "Cancel Subscription." Please note that since all formulas are fully customized, we cannot accept cancellations, returns, or apply refunds after your order has been billed and processed. All cancellations will apply to the following scheduled delivery.

Once you have successfully canceled your subscription, you will receive an email from us confirming that your subscription has been canceled. If you do not receive this email after 24-hours, please reach out to us here so that we can help!

At this time, we’re unable to create and package multiple sets for the same order. After placing an order though, it should be simple enough to go through and place another one, as we securely save your details in your account.

If you feel like your first order of custom hair care, skin care, or body care hasn’t met your standards, let us know. We truly want to hear from you so we can improve your experience, and the experiences of others.

Reach out to us at hello@functionofbeauty.com with the details of your concern within 30 days of receipt of your first order and we'll do our best to address your needs with a free one-time reformulation.

Great question! You choose a shampoo and conditioner based on your natural hair type, choose up to 3 #hairgoal booster shots - then snap, pour, and shake to activate. You can find out more here, or watch this short Youtube video.

No, you don’t need to (but we always think the more the merrier!). You can buy 1, 2, or 3 - but not more than 3, as it won’t all fit and mix properly.

For best results, yes! Of course, you can add the booster shots to your current shampoo and conditioner, but we can’t guarantee luscious locks. ;-)
