Makes my hair so soft and healthy! BUT
Color: Biotin
I bought this obviously as a heat protectant for my hair. Most heat protectanta leave my hair with texture, like an almost sticky straw like feel to my hair. I thought that was normal. This one though leaves my hair silky, soft, smooth. It literally is so soft to run my fingers theough and takes down my flyaways/breakage from damaged hair. It has increased the quality of my hair so much it feels young and healthy again. HOWEVER, as much as I love this product , because of how soft it leaves my hair, my hair doesn't hold a curl when I use this. I wear beach waves most daysr and once I've used this my hair doesn't want to curl AT ALL. it feels equivalent to curling my hair in humidity. By the time I get to the second side, the first side has fallen out. It took me a while to realize it was how soft this product was leaving my hair that was the culprit. I've decided I don't care and am just figuring slightly different ways of styling my hair with less curl than I'm used to because I'm going to keep using this product for everything it does for me.
OH! Also I bought a bottle and after like a hundred pumps nothing ever came out so I exchanged for a new one and the second did the same thing, I figured they couldn't both be broken so I just kept pumping and pumping and pumping (literally way too many times) and it finally started spraying and has been working perfectly fine. So just keep pricing that pump for what feels like forever and it'll start working for you! I highly recommend this product

Protects from heat and damage
Color: Biotin, Color: Biotin
This spray claims to protect hair from heat damage and strengthen it with biotin. I've noticed a significant reduction in frizz when using heat styling tools, and my hair feels stronger and looks healthier overall.
The spray has a lightweight texture that doesn't weigh down my hair or make it greasy. It distributes evenly through damp or dry hair, making it convenient to use before styling.
The scent is subtle and pleasant, not overpowering. It provides a decent level of heat protection.
The spray bottle is practical and easy to use, though a lock mechanism for travel would be helpful to prevent accidental spills.
I would recommend the Biotin Hair Protection Spray to anyone looking to protect their hair from heat damage and strengthen it over time.
