Personal Experience

If you’re looking for a personalized hair care experience, Function of Beauty might be the right choice for you. With their custom shampoo and conditioner, you can choose your hair type, hair goals, and even the scent and color of your products.

When I tried Function of Beauty, I was impressed by the level of personalization. The products arrived in sleek, minimalist packaging, and the scent I chose (peach) was subtle and pleasant. After using the products for a few weeks, I noticed that my hair felt softer and looked shinier.

However, it’s worth noting that Function of Beauty’s products can be more expensive than some other hair care brands. Additionally, the customization process can be overwhelming for some people, with a lot of options to choose from.

Pros and Cons

Here are some pros and cons to consider before trying Function of Beauty:

Personalized to your hair type and goalsCan be more expensive than other brands
Customizable scent and color optionsCustomization process can be overwhelming
Products are cruelty-free and veganMay not work for all hair types

Overall, Function of Beauty can be a great choice for those looking for a personalized hair care experience. However, it’s important to weigh the pros and cons and decide if the higher price point and customization process are worth it for you.

Function of Beauty Alternatives

When it comes to personalized hair care, Function of Beauty has several competitors in the market. Two of the most popular ones are Prose and Formulate. Both brands offer customized hair care products for a variety of hair types, just like Function of Beauty.

Prose’s hair quiz is much more comprehensive and offers a wide range of products, including a pre-shampoo hair mask and hair oil. However, Function of Beauty is more affordable and customizable.

Function of Beauty also offers a subscription service that includes a 20% discount on shampoo and conditioner, and the ability to add on exclusive products like a wide-tooth comb and cute toiletry bag with reusable bottles and hair ties.

Formulate, on the other hand, has a similar quiz to Function of Beauty, but with fewer options. Formulate also offers a subscription service, but their prices are higher than Function of Beauty’s.

Ultimately, the choice between these brands comes down to personal preference, budget, and hair needs. If you’re looking for a more comprehensive quiz and a wider range of products, Prose may be the better option.

If you’re looking for affordability and customization, Function of Beauty may be the way to go. And if you’re looking for a more premium option, Formulate may be the brand for you.
