FREQUENTLY ASKED QUESTIONS
What is the main benefit of the Glycolic Gloss Leave-in Serum and the overall Glycolic Gloss range?
The Glycolic Gloss Leave-in Serum is designed to transform your hair by delivering next-level shine and smoothness. Its primary benefits include instantly enveloping each hair fiber with a protective glaze, resulting in 14X smoother, silky hair that radiates a brilliant glossy finish.

How does the 4% Glycolic Acid Complex work across the Glycolic Gloss range to improve my hair?
The Glycolic Acid Complex in the Glycolic Gloss range, particularly concentrated at 4% in the serum, works by laminating the hair cuticle. This process creates an instant shine glaze, for silky, smooth, and hydrated hair. Across the shampoo, conditioner, and leave-in serum, Glycolic Acid plays a crucial role in reducing fluffy hair, taming frizz, and flyaways, making your hair incredibly soft and more manageable by sealing the hair cuticle for a mirror-like shine.

For optimal results and a complete hair gloss treatment, begin your routine with the Glycolic Gloss Shampoo to cleanse and prepare your hair. Follow with the Glycolic Gloss Conditioner to nourish and detangle. Finally, for that extra boost of shine and smoothness, simply apply the Glycolic Gloss Leave-in Serum onto dry or damp hair lengths. It serves as the perfect final step in your hair product routine to lock in gloss and manageability.
What kind of results can I expect to see after using the full Glycolic Gloss routine?
After using the complete Glycolic Gloss routine, the shampoo, conditioner, and leave-in serum, you can expect immediate and noticeable improvements. Your hair will be visibly shinier from the very first application, achieving a brilliant glossy finish. You'll also experience 14x smoother, silkier hair that is incredibly soft, more manageable, and free from frizz and flyaways. This powerful trio leads to overall healthier-looking, hydrated, and radiant hair.
Is the Glycolic Gloss range suitable for all hair types, especially if my hair is fluffy or damaged?
Yes, absolutely! The Glycolic Gloss range is an essential hair treatment designed to make hair silky, smooth, and hydrated. It's particularly effective for those experiencing fluffy hair, as the entire system works collectively to reduce fluffiness and tame frizz and flyaways, contributing to a radiant and polished hair care routine for a wide variety of hair types seeking enhanced shine and smoothness.

100/10, except for the strong perfume scent, ug
a month ago
The product performance is 100/10. I have thick, wavy, color treated hair. I’ve used this twice on dry hair and my blonde hair was transformed, shiny, like natural/pre color treated hair and de-puffed. I love this, BUT, the smell is overwhelming and does not dissipate over time. The scent is very strong, notes of cheap perfume and synthetic sweet fruitiness.
Yes, I recommend this product.

Not good at all.
a month ago
I have always used Loreal hair products and never had a problem with it. Until I got the glossing elvive line. I have always had long thick hair that everyone would compliment, but this product would make my scalp itch super bad and have me getting out of the shower with a whole wad of hair in my hand. I’ve kept useing it cause I didnt realize it until after so many washes. My hair felt so dry and crunchy and now I am left with so much breakage and it’s so upsetting. My mom used the same shampoo and conditioner and woke up with new significant breakage as well. We are both blondes with color and I would not recommend this product..

Amazing results
4 months ago
To preface- I have really easy to manage hair (straight/black/thick). I pair the serum with leave in conditioner with argon oil infused with it.
This product has really added so much shine and vibrancy to my hair. It took a while for me to see the results about a month of consistent use, hence 4 stars.
Another aspect I noticed is my hair holds more moisture than before integrating it with my hair care. I know glycolic acid helps with moisture absorption but I wasn’t expecting such amazing results.
Truly the most bang for your buck and I will be repurchasing this serum.

Overpowering, unpleasant fragrance
4 months ago
I want to love this product, because it makes my fine, straight hair so happy. Unfortunately I can't get past the scent, which is so strong that it lingers on my hair and even my hands for hours after use. I'm not a fan of the scent anyway, but I would tolerate it if it dissipated at all. It's too overpowering, though, and leaves me nauseated after smelling it all day. I'm so sad to have to toss the bottle.

Extreme hair loss
4 months ago
I would give this product is zero or maybe even a minus score if I could. After about 4 weeks of using glycolic gloss my hair was falling out so rapidly I became bald from my forehead to the crown in a strip about 5 in wide. Thankfully my hair has slowly recovered since I quit using it. With all of the negative reviews and the reports of hair loss this product should probably be taken off the market.

Terrible
5 months ago
I wanted to give L’Oreal’s hair gloss for silver white hair a five star. But I can say this, I will never buy that again. It burned my scalp. I left it on for 11 minutes and it turned my hair darker than what the box claimed also burned and irritated the back of my neck and wherever it dripped down.
So if you have sensitive scalp, I would be aware
