What customers say
about Function of Beauty
Delivery was quick, and the results are noticeable: my hair feels healthier and my scalp less itchy.
Holy grail of haircare! My hair has so much more volume then ever before and almost no frizz after blow drying
Love their hair serum and hair mask. My hair texture has dramatically improved ever since I started using their products in 2020.
The bottles decreased in size from 16 to 11oz which is a BIG difference yet the prices stayed the same or even increased a bit.
They refuse to refund me on a subscription that I had cancelled.
The problem is not the product but the customer service.
