Function of Beauty

While i love the product and think it can do wonderful things for your hair I do find it inconvenient that you cannot just walk to the store and pick some up.

I did this customization and there was nothing special about it. I didn’t love it and it wasn’t doing the best for my hair so I just didn’t finnish the bottles and I gave them to my mom to use the rest because she uses anything.

I have used it multiple times this time being the worst I had canceled my subscription prior to this month so I would not receive new shampoo or conditioner yet I still did 60 dollars worth of product I don’t want and won’t use it did nothing for my hair made it feel like straw if anything and it said you could get the purple one for blonde hair yea no I think I’ll stick to my 8 bottle of purple shampoo from Walmart personal opinion not worth the money !!!

After Kheils discontinued my favorite shampoo I've been on the hunt for a mid-priced haircare line that specializes in dry hair and I while I love the concept of this product, after 2 months of use I just didn't feel like I got the benefits it touts. I even used the pro line as opposed to the line they carry at Target. 

I was allergic to the product and it didn't really do anything for my hair

Well I used it long ago and this shampoo cause my hair to shed. Even year after stopping my hair still sheds. I should have known since it had the same scent as the shampoo from different brand that also caused my hair to shed. 
And back to company , I read a lot of reviews that had the same issues. 

Unfortunately, their hair care did nothing for me. It left my hair feeling really oily and gross. :( 

I love this product. My hair is naturally very curly and never in my life have my curls looks so defined. The online quiz is super easy and I always receive my product quickly. The only drawback of this product is the scent/color range. I wish the brand offered more natural scents/colors, but c'est la vie!

Function of Beauty left my hair super oily and I was not satisfied at all. The only thing I liked was the cute packaging. 

I signed up for a $5 trial. While I have sensitive skin and a sensitive scalp, this is the first time a shampoo/conditioner has ever actually made my scalp 'burn' - I reached out to customer service, and they got back to me very quickly with an apology, full refund, advice to immediately cease use, and a complete and total breakdown of my formula to go over with my dermatologist so as to track down my exact allergy. Given the experience, I can't really recommend them, but it's also not as though it could have been predicted, and the customer service in response was as excellent as I could have expected.

I didn’t mind the products, and I did feel like it lasted me a long time, however it felt like it didn’t “wow” me so I moved along to other products. 

The good: the scent is absolutely heavenly and potent when using and the heat protectant is amazing and leaves my hair silky smooth after straightning.
The bad: pretty sure I lost more hair when using this than any other shampoo and conditioner and the smell loses its potency and becomes non existent once washed off :( 

Love all the different options they have when it comes to hair texture for the shampoo and conditioner. Smells great, and leaves my hair feeling soft AND affordable!

Pro:
-Customization: Cool scents, choose your own scent level, Cool color options and packaging 
-Convenience: less time searching for specialized products for my hair type

Cons: 
-Expense: Three 16oz products (Shampoo, conditioner, and go wash) cost $79.98 pre tax
- Slow shipping: I ordered March 26th, it shipped March 9th 

The quiz is fun and I appreciated that they do the hard work of selecting proper products for your hair type. I’ve used the product once and it left my hair hydrated and smelled great. I’ve used cheaper products and gotten similar results. I’ll see if I see any additional benefit with longer term use. I’m not sure if I’ll order again, especially with the recent price increase.

Unrelated, they shipped me 3 pumps, but only one straw attachment. :(


I enjoyed the products I received. I love the ability to customize the product to your liking based on your hair type and/or concern. It definitely worked wonders on my color treated hair. 

After hearing a lot of great things about their customized hair products, I was excited to try them out for myself. Even though I customized my products to be moisturizing, the shampoo and conditioner I received left my hair feeling dry and stringy. I did love the fact that you could customize the scent of your product and hope that more companies may offer this in the future, but the products themselves were sub-par, at best. 

I loved Function of Beauty! I tried got to choose all the attributes of my shampoo-- I wanted volume with shine and split-end repair. I also got to choose the scent and the potency of the fragrance, which was amazing because i loved heavily scented products! 

The shampoo and hair mask worked beautifully! My hair was voluminous and shiny and the simplest packaging looked lovely in my bathroom. 

To be able to order one shampoo without the conditioner and vice versa.

Love these products ! I have very oily hair and always struggled to find the right shampoo. With this one, on the other hand, the texture and smell is wonderful. No more oily scalp for the win.

My hair has never been more, smooth, soft, and damage free than when using these products 

This system has done such wonders for my hair! I started with damaged hair and my hair is slowly becoming more and more healthy each wash

I have used their wavy hair shampoo and conditioner for the last 4 years. I love the way it helps my hair become wavy and soft. I love the fact that I can customize each bottle to best suit my hair goals.
