Have you heard of Function of Beauty? It’s a company that specializes in custom made shampoo and conditioner that you personalize to fit the needs of your specific hair type!
Their laboratories are located here in NYC. If you want to actually go there to make your shampoo or conditioner, you have to set up an appointment on their website - click here.
However, if you're not in NYC or if you just can't get an an appointment, you can always order it online so it can be shipped to your home.
I did a full video review about it, so if you want to know more, check it out!
