Worth every penny

I never write reviews but felt like I should share . I absolutely love this serum . Living in Fl I always have to straighten my hair or its frizz city . When I use this I do not ! It’s defrizzes my hair smells amazing and is so light . Only takes one pump so will last a few months . I think I found my new holy grail . If you’re debating get it ! You will not be sorry .

When I heat style my hair, I'll split my hair in half and apply 1 pump to each half then style and it always gives me the softest and shiniest look. Even got when I wear my hair natural after it's done air drying I'll apply 2 pumps for my whole head and do the praying hands method then scrunch and it leaves me with soft and shiny curls. 10/10 love this product so lightweight and smells amazing

I'm impressed with how it really makes my hair sleek, not weighed down. I find the key is to make sure the hair is damp then add the product, then blow dry so the hair is very dry, and then follow with a flat iron. Its almost as good as smooth n' 'shine a product hard to find anymore.
