I live this shampoo. The scent is beautiful but not overpowering. I love that we can customize the scent and change it on reorder. My hair is soft and manageable. Keep doing what you're doing and thanks for a great product.

SOS Custom Repair leave - n- treatment

9 months ago

I was truly at a lose for shampoo and conditioner until a few years ago when I came across function and actually sat down and took the hair test. Then, I started using it all of the time and never changed back. I have used it every since. My hair is so much healthier and looks so much better. I dye it at home, and it has the option for home dye treatments for your hair. Just try it you will fall in love.

Great product! But. . .

It feels great in my hair, but i always ask for a strong scent of coconut and for the last few purchases, it does not smell like coconut at all. I really would love to have that blissful coconut scent again.

It made my hair dry and tangled.

10 months ago

I need to see if they’ll accept a return/refund on this. I think the SOS line is simply not effective FOR ME. I was finding my hair to be dry and tangled after switching to my new SOS shampoo ; conditioner. I switched back to use up the little remains I have left of my normal Function of Beauty fully custom shampoo and conditioner, and my hair returned back to normal. I think this is simply not for my fine, curly hair type. It’s probably great for people that have thicker hair? Not a clue. I followed the directions on the products and everything, I guess it just doesn’t work for me.

My holy grail :raised_hands::skin-tone-3::raised_hands::skin-tone-3:

10 months ago

I have been using Function of Beauty for a few years now, and it is the ONLY brand I trust for hair care. The shampoo smells delicious, my hair is soft and shiny, and ever since I added the goal for length, my hair has grown down to my waist. This is the most trustworthy and amazing company ; I will continue to recommend it to everybody!
