Read our Editorial Guidelines to learn more about what makes our site the premier resource for online health information.

Luseta Beauty is a cosmetics brand that’s famous for their purple shampoo. The brand claims that their shampoo “helps to thicken and texturize” hair and also “strengthens and fortifies the hair shaft.”

But does Luseta Shampoo contain ingredients shown in medical studies to improve hair quality and hair health or are these just marketing claims? Does it contain any questionable additives? What retailer sells Luseta Shampoo for the best price? And how do real users rate and describe the effects of Luseta Shampoo?

In this article we’ll answer all of these questions and more as we analyze the ingredients in Luseta Shampoo based on medical studies to give our take on whether it’s likely to be effective or if it’s a waste of money.

We’ll also publish a cost breakdown to show which retailer sells Luseta Shampoo for the best price, and feature Luseta Shampoo customer reviews.

Ingredient Analysis

Luseta Shampoo ingredients

The ingredients in Luseta Shampoo, called Biotin & Collagen Shampoo, are shown above.

There is only one active ingredient in this shampoo that we can find research backing for in regard to improving hair quality.

Argania spinosa (argan) kernel oil was shown to protect hair against damage in a clinical trial published in the Journal of Cosmetic Dermatology.

We cannot find any research suggesting that the two ingredients highlighted by the brand in the actual name of the product (biotin and collagen) can improve hair when applied topically.

Biotin is typically used as an oral supplement rather than topically, and a 2017 medical review analyzed the effectiveness of biotin for hair growth and concluded the following: 

“Though its use as a hair and nail growth supplement is prevalent, research demonstrating the efficacy of biotin is limited.”

We can’t find a single clinical trial showing that biotin is effective when applied topically, nor does the brand cite any on their product page.

Hydrolyzed collagen can help promote hair growth when taken orally, but we can’t find any research suggesting it’s effective when applied topically, nor does the brand cite any.

Luseta Shampoo contains several inactive ingredients that may be questionable from a health perspective.

Parfum is another term for fragrance, and this ingredient has been clinically shown to cause negative effects on human health as we documented in our Briogeo reviews article on another shampoo brand containing this ingredient.

Phenoxyethanol, sodium benzoate, potassium sorbate and benzyl alcohol are all preservative ingredients, the first of which was shown in a 2020 clinical trial to be toxic to human cells.

CI 17200 and CI 60730 are synthetic dyes used to give the shampoo its purple color. A 2015 medical review reports that synthetic dyes can be absorbed through the skin, and can have toxic effects in the body.

We think that this shampoo has far too many questionable ingredients to use regularly, but how do real users rate it? We’ll review in the next section.

Where to Get the Best Price

Luseta Shampoo is sold at a variety of online retailers. Here’s a price breakdown at the time of publishing this article:

Brand website: $16 (plus $5.95 shipping, link)

Walmart: $17.50 (third-party seller, link)

iHerb: $12.93 (plus shipping, link)

Amazon: $12.99 (free shippinglink to official Amazon listing)

Luseta shampoo is 41% cheaper on Amazon than on the brand’s website when considering shipping costs, which is one of the largest discrepancies in any shampoo review we’ve published to Illuminate Health.

Real Customers Review Luseta Shampoo

Amazon is a better resource for honest customer reviews than a brand’s website in our opinion.

Luseta Biotin & Collagen Shampoo has been reviewed over 1,700 times on Amazon, with an average review rating of 4.4 out of 5 stars.

The top positive review from a verified purchaser comes from a user named “Cassidy” who liked the aesthetic effects of the shampoo:

“Once it dried it made my hair really soft and silky, it's been sooooooo long since my hair felt that good after using a hair product since it's damaged. I'm not sure if it was just the Shamp&Cond or of the combo with the glossy pearl oil made it that way but either way I'm super happy was was really surpised. Deff think it's worth the money now.”

The top negative review from a verified purchaser named “Stephanie” who claims the shampoo caused irritation:

“I purchased this because my hair is damaged and dry also it’s very brittle. Well this conditioner did NOT deliver what it says it does. My scalp was very itchy. My hair felt extra dry and brittle. PLEASE SAVE YOUR MONEY AND YOUR HAIR.”

Luseta Beauty has responded to all customer complaints on their Better Business Bureau (BBB) page attempting to resolve the situation, which is a sign of a high-quality brand.

We consider Luseta Shampoo to have one of the worst formulations of any shampoo we’ve reviewed on Illuminate Health.

We’re only able to identify one ingredient we consider likely effective for improving hair quality (argan oil), and this shampoo contains a number of questionable additives, including artificial dye, fragrance and four different preservatives.

Luseta doesn’t cite any clinical studies on their product page suggesting that the two active ingredients from which this product gets its name (biotin and collagen) are effective for improving hair quality when applied topically. We can’t find any studies proving such.

Luseta is affordable, but we believe there are similarly-priced brands with greatly superior ingredients both in regard to efficacy and safety.

For consumers intent on purchasing Luseta Shampoo, Amazon currently has the best prices by a wide margin.
