Love it
Makes my hair feel so soft and smooth without weighing it down. Adds a nice shine and helps with frizz. A little goes a long way!

Wow
Love the smell. One pump is enough for my thin long hair before blow drying. Keeps my hair soft and smooth.

Use sparingly
Store the bottle upside down for easy use. A little sticky but does an excellent job at protecting the hair. Don’t use on scalp if you have thicker hair as it’ll weigh it down

Good for shine and volume
It’s ok but dosent control the fizziness of my hair so it’s not incredible but it works in detangling and keeping my hair straight after I get out the shower
