Jasmine Russell –
I’ve used this leave-in for a few weeks now and my hair feels stronger and less frizzy. It adds shine without weighing down my curls. The heat protection is noticeable when I use my flat iron. My colour hasn’t faded as much as before, which is a big plus.
Hannah Miller –
Great product for maintaining healthy hair. It tames frizz and makes my hair smoother. I apply it after washing and before styling. The shine is noticeable, and I feel like my hair is more resilient after each use.

After switching from a regular leave-in, I noticed less breakage and better hold in my curls. The acidic formula seems to protect my colour well. I use it every day and haven’t had any colour fading issues yet.
