It’s pretty easy to order. You can fill it out right on Facebook. You pick the necessities you want for your hair, the scent and even if you want it colored or not. It comes in a bottle with a lid and then they also send you pumps which make it was easier. It’s cute seeing your own name printed on your bottles as well. They give you sticker sheets to make them look neat so def try this stuff! They’ve got auto ship so be aware of that

I purchased the straight hair (blue) shampoo and conditioner! BEST DECISION EVER! I was having issues with other brand such as sauce, tresseme, herbal essences, etc.. they never made my hair feel clean! Function of beauty has not only felt healthier but looks healthier. My hair stylist was shocked at how beautiful my hair felt and looked!Function of Beauty

I’m about halfway through my first set of custom shampoo and conditioner, and I’m really noticing a difference in the health of my hair. It has also added some volume to my usually fine and flat hair. A little bit of the shampoo goes a long way, so this makes the price tag worth it to me and I will definitely be repurchasing it in another scent/color combo when I run out!

I was excited to purchase a custom blend for my hair. I wanted smoother hair, something that can help dandruff, and keep it healthy. I purchased a custom shampoo and conditioner since I’ve heard a lot of positive reviews about FOB. Previously to this, I was using clean formulas and my hair was pretty healthy. Unfortunately, the shampoo made my scalp so itchy every time I used it. It also made my scalp flake so much. I honestly ended up throwing away the shampoo and conditioner. I did love the fragrance of these products, but definitely not worth it for me.

This product has it ups and downs. The function of beauty stays grounded with what they put in it, per request. I like that you can create a mixture that is good for you. However, this shampoo can leave some sense of grease leaving my hair greasy which most people do not enjoy. Either way I do think that this product benefits my hair.

I love this product!! Makes my curly hair so soft and smooth. I love that you can choose the scent and what’s in it. The smell from the lotion lasts all day.

I’ve been using the brand function of beauty for my shampoo and conditioner for about a year now. For me, the 16 oz sizes last me about 3 months each and my hair is pretty long at about 2 feet. I would say that overall, I liked the customization, and the goals I set in the quiz were fulfilled. However, I’m not sure I can justify the price. I think that I could likely find a shampoo & conditioner for half the price that could do the same job. I’m only taking off one star because it is a great company with fantastic customer service and a quality product. The only limiting factor is the price, but keep in mind that it is completely customizable to fit your own hair needs.

I love that you can customize their products to meet your hair goals! For me, one hair goal was to reduce frizz, and I think the shampoo and conditioner has made a difference! You can even choose a scent and the colors you want! Highly recommend!

HIGHLY recommend the purple shampoo for brassy hair. I have ZERO gold/orange to my blonde hair. Even my hairdresser can’t believe how well it works. It even works better than professional toners.I leave it on for 5 minutes in the shower and rinse.

i don’t recommend it! it’s too expensive for it to not really do much good for my hair. there’s so many other options if you’re willing to spend the money, like Moroccanoil, Olaplex or SheaMoisture (super affordable alternative too)
