Reviews

Nice product for shine!

"This gloss is lovely. Feels great in application - not too heavy - and rinses out well (like conditioner). The shine on my hair wasn't overly noticeable but I do like the product!!"

Didn’t work for me at all

"Thus was of no use to my hair at all"

Grace P. (1/5)

Do not recommend

"I’m super disappointed in this product. It made my hair feel dryer, duller, and almost like straw. I have thick, straight hair and this made it so much worse. Do not recommend."

Q&A

How do you use the product -- i.e., is it leave in or rinsed out? What are its ingredients?
Hi - Simply wash and condition your hair as usual, then apply the gloss, leaving it in for just 5 minutes before rinsing. Regrarding ingredients - Unlike traditional methods that rely on only smoothing the hair's surface or coating it with silicones to reflect light, our Light Enhancing Technology is engineered with the science of shine at its core and combines an optical brightener and a high gloss emollient. · The high gloss emollient smooths the hair surface, increasing the amount of light reflected off the hair, so they act like tiny mirrors, which ensures every strand reflects light. · The optical brightener absorbs and then converts non-visible UV light to visible light, increasing brilliance on the hair’s surface, it’s like flipping a switch to lightbulbs on your hair.
