    So I bought the shampoo and conditioner and I haven’t used it yet because I’m not done with my other shampoo BUT I’m scared of trying this brand I love my hair a lot and I want to keep the waves and texture of my hair. I’m not sure what to do and I want an opinion because I really don’t want to damage my hair

    I am so glad I found this article because something you said resonated with me so much- i’ve been using my function of beauty products for four months now and just recently I noticed how greasy the inside of my hair is well after my hair has dried from washing. I realize now it’s because of what you said, how if you choose “deep condition“ and “fix split ends“, you can end up with products that are not the best for your scalp and can make it greasy! That has to be what is happening to me! And it’s annoying because I just realized this right as my second shipment is coming to me with that same formula. I found a phone number for the company and I’m going to try and call them today. I emailed with them yesterday and found the exchange annoying although in the end the rep did recommend the same thing you said, to replace those two choices with others. Well, how would I have known that? They should not offer choices that will make your scalp greasy! Great article :)

      I’m glad my post helped! I agree, that’s definitely the danger of leaving these choices up to the consumer with no guidance, because our natural instinct is to focus on the state of our hair and not our roots. I hope the new version works better for you!

        FoB equates Environmental and financial waste.

        The pump bottles don’t work, I got in contact with them, they offered 50% off my next order.

        Ridiculous stickers for your bottles that just end up being on the shower floor.

        • Jenny says:

          Yeah mine broke too which is ridiculous, but stickers aside, aren’t they just as wasteful as any other hair care brand?

          I personally liked the stickers and mine stuck well, but it would be nice for them to give users the options to opt out of getting them!

  3. Thank you so much for your honest review Jenny! I’ve seen Function of Beauty everywhere on social media and I’d love to give them a try <3

    I’ve been using FoB for about 6 months since my sister got me some for my birthday, and I really like it. They do have silicon-free options in shampoo and conditioner, though not in mask, leave-in, or serum, so that’s nice.

    Hi Jenny! I can’t thank you enough for this very detailed, well thought-out review. I, too, have a finicky scalp and selected the same 5 goals for Function of Beauty. Also, thanks for the pro tip about getting a larger shampoo vs conditioner! I will be purchasing through your links as a token of my appreciation for this post!

  6. Thanks for the review and comparison! I do have a sensitive scalp so i should really consider custom shampoos as well. Have you tried Vitabrid? That’s on my list too. I’ll stick with Christophe Robin and Sachajuan masks and conditioners. I am very intrigued by this serum though so will look into that.

  7. I haven’t heard about these guys before. Then again the only social media I make rounds on these days is Twitter. I am a little weary about custom formulas. They do sound like the bees-knees. Who doesn’t want something formulated specifically for their needs. But something about it doesn’t sit right with me. I almost always feel like they create three basic profiles and catalogue you into one of them with the sprucing of being unique to you. I personally haven’t tried any myself but I do have a friend who had tried something after a recommendation from a work colleague and ended up with the same product as hers. Not that Function of Beauty had anything to do with the above!

  8. I’ve never tried the brand before but I’ve seen so many ads on YouTube for it! It was really helpful seeing the brand broken down like this, the products sound great! xo

    My hair is pretty average I d say, so I never looked much into customized hair care. It is good to see that they improved though, and really nice that you gave them a second chance.

  11. Brilliant review and I appreciate the comparison, Jenny. I am toying with the idea of getting a balayage but I honestly couldn’t be arse with the maintenance and am quite happy with my low key shampoo + conditioner routine. Maybe if I have a finicky scalp and higher maintenance hair then I would try Function of Beauty.
