Olaplex - IceE81 review for No. 7 Bonding Oil

I brought this Olaplex bonding oil as I have dry 4c hair that lacks shine. I tend to use it when my hair is dry. I add a palm full , and it gives my hair a nice shine. I do find that towards the end of the day, the shine is waining, so I have to use it regularly to keep the shine. This oil is also good for heat protection. So after putting it in my hair, I straighten it. The oil helps to prevent heat damage. It is supposed to shorten drying time. I can't say I've noticed any difference in this aspect. It's vegan, alcohol free and fragrance free. .
