Disclaimer: Hair Mask and Hair Serum were sent by Function of Beauty for review. Opinions are my own.
Happy October! The leaves are starting to change and I’m wearing sweaters again. the most magical time of the year!
Today I’m reviewing the two newest products from Function of Beauty that launch today!
Introducing the Custom Hair Mask and the Custom Hair Serum!

I’ve previously reviewed Function’s shampoo and conditioner and leave-in treatment. That blog got deleted with my other blog entries when I switched blog platforms. But here’s a TLDR:
- Did not like the Shampoo and Conditioner. Thought it was too stripping and did not clean well
- Liked the leave-in
- Think the reasons I did not like the S&C was because of my hair goal choices
Moving on! Based on my past experience, I decided to approach these products differently. Every Function of Beauty order is custom made for you! You begin your order with a quiz to build your hair profile(Hair Type, Hair Structure, and Scalp Moisture) then you select your hair goals, fragrance, and color.

I approached my Hair Goals a little differently this time. You can choose up to 5, and in my first function order I chose 5 without thinking about them. This time I thought about what I really wanted, and also what goals would compliment each other. I ended up only choosing 4 this time but the experience has been so much better!
For fragrance I picked ‘Feeling (f)ineapple’ a yummy pineapple coconut mix. You can customize the color of the hair mask(I forgot to do this) but not the hair serum.
Now onto the Reviews!

Review: I love this hair mask! I’ve used it 3 times and my hair was soft and shiny and smelt wonderful all day! Function recommended I leave it on for 5-10 minutes, which is the perfect time frame. The little comb they sent is perfect for dispersing the product through my thick, wet hair. Also works great as a quick conditioner as well. And $19 dollars is not a bad price for almost 8oz of hair mask.
Custom Hair Serum

A lightweight, customizable finishing product that’s designed to help enhance shine, smooth frizz, and increase hair’s overall manageability. Apply as a styling or finishing product.
Quick Facts:
- 3oz bottle
- $19
- Customizable Color and Scent
- Key ingredients include Argan Oil, Jojoba Oil, Anatto Oil, Sunflower Oil.
- Can be used on wet and dry hair.
Review: Overall, a solid product! It has not replaced my beloved verb ghost oil as a daily finishing product, but I do enjoy it a lot. It’s not heavy or greasy, and does give an great smooth, hydrated look. I only use it on wet hair, so I can’t speak on how it performs on dry hair. But definitely a fan!
