Key Ingredients





How to Use

Apply a quarter sized amount of Fondant Extentioniste conditioner to wet hair, working from mid-length to ends.
Leave in for 2-3 minutes and rinse thoroughly.

Don't forget to apply to the nape area of the head where there can be a lot of hidden damage due to friction with clothing. Also, be mindful of what is physically breaking your hair such as purses on your shoulder or tearing out ponytails!

Complete your hair care routine with cleanse, treat, prime & night essentials.

Rated 5 out of 5 by from Full body I have been using the Fondant condition for a couple of years at the recommendation of my colorist. I leave a small amount in and T-Shirt wrap/dry. This process has been successful in my curly hair not getting frizzy and keeping soft curls longer.
