got questions?

What’s the difference between co-wash, conditioner, and shampoo?

Co-wash is a cleansing conditioner used between shampoos to gently cleanse the scalp and hydrate hair at the same time, never stripping the hair + scalp of natural oils or drying it out. It's formulated to be lighter on the roots than a conditioner, and it’s not as drying or harshly cleansing as a shampoo.

What hair types can use co-wash?

Co-wash is specifically created for curly and coily hair types (as well as color-treated hair) that sometimes find shampoo to be too drying for their hair, too difficult to detangle, and/or want to be able to refresh their hair between shampoos. While co-wash is recommended for curly or coily hair types, straight and wavy hair can still use it - your hair might feel weighed down or you may find you need to wash sooner than you would using regular shampoo when washing with co-wash.

How often should co-wash be used?

Co-wash can be used 1-2 times per week to gently cleanse hair and scalp in between wash days. We recommend using Function of Beauty shampoo every 2-3 weeks (in place of your co-wash) to fully cleanse the hair and scalp from any potential build-up.

Should I use co-wash with my Function of Beauty shampoo and conditioner?

We recommend using co-wash alongside your Function of Beauty shampoo and conditioner for an optimal wash routine. Adjust usage as necessary, but if you have curly or coily hair, or dry, damaged, or color-treated hair, we recommend using co-wash and conditioner together regularly, and shampoo once every few washes to more deeply cleanse the scalp of any build-up.

What does it mean to be Curly Girl Approved?

Curly Girl Approved products are made to keep curls happy and healthy-- always silicone-free, sulfate-free, free of drying alcohols, some soap ingredients and non-soluble waxes. Function of Beauty is not associated with Lorraine Massey, the Curly Girl Method (“CGM”), or Curly Girl: The Handbook.
