Reviews

Brilliant

"I am a little salt & pepper these days and have lots of new growth and hair gets frizzy, this is magic, really makes the hair sleek and smooth. Definitely recommend"

— Julie B. (5/5)

Senior hair

"Replenish that fading shine"

— Jeffrey F. (4/5)

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."

— Paige (1/5)

Amazing Product

"Amazing product. I have wavy, frizzy hair and this does exactly what it says. Had many comments on how healthy my hair looks. I also don’t need to put any other smoothing products in my hair which is great. I would say that it is essential to remove the excess water in order for this to work properly and that is based on personal experience"

— Rachel G. (5/5)

Worth it!!!!

"Ok, I admit I was skeptical! However, my very first use (adding it in with conditioner and letting it sit for 5-6 mins) and the softness and low frizz that followed was A-mazing!! I am a 2C/3A hair type with medium coarseness and this really tamed my wild frizz! I’m a believer!!"

— Kena G. (5/5)

Very disappointed

"I was excited to see if this would shine up my slightly grey lackluster hair. I’ve used it twice and it does nothing but make my hair look dirty sooner."

— Kim D. (2/5)

What an amazing product. My

"What an amazing product. My fine hair has never had such a shine!"

— Susan M. (5/5)

Amazing fit

"Better than buying in amazon because on your site things are not expired."

— JUAN M. (5/5)

Unimpressed

"Not really giving much shine and doesn’t smooth over hair like you see in the ads. You end up using a considerable amount in one wash so wouldn’t say it’s worth the price tag. Influenced on Instagram and not happy with the results."

— Betsi T. (3/5)

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.
