Just a great product
Scent: Curly
Honestly I’ve tried plenty of hair mask before and none of them can do what this one does! My hair is so hydrated after 2 uses! When I wash it out my hair actually maintains the water and it’s so easy to comb through and style 10/10

Fantastic heat protection
Color: Biotin, Color: Biotin
I highly recommend this heat protecting spray because it has truly helped my hair become healthier. I blow dry and straighten my hair so much and I rarely use to protect it so it became quite damaged over time. I've been using this for roughly 3 weeks now and my hair is becoming healthier, shinier and growing so much better because it's not breaking or getting dried out. I like the smell of the spray - it's really nice. It's not sticky and doesn't leave any residue in my hair. And it doesn't leave my hair stiff like it's got hair spray in it. This spray stops my hair from going all frizzy including when I'm hot or it's humid. It also protects my hair colour too. I would recommend this.

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
