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 appearance? Does it contain any unhealthy ingredients? Can purple shampoo ruin hair? And is Luseta Shampoo better or worse than popular shampoo brands like Native Shampoo?

In this article we’ll answer all of these questions and more, as we analyze the ingredients in Luseta Shampoo to give our take on whether it’s likely to be effective for improving hair quality, and whether or not it's healthy.

We'll also share a video examining whether purple shampoo can damage hair, and compare Luseta Shampoo to other popular shampoo brands to pick our winners (and losers).

Key takeaways:

• Contains some hair-promoting active ingredients
• Contains many unhealthy inactive ingredients
• We don't currently recommend Luseta Shampoo

Ingredient Analysis

The ingredients in Luseta Biotin & Collagen Shampoo are shown below:

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.

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.

Overall, we do not currently recommend Luseta Shampoo due to the inactive ingredients highlighted above.

Can Purple Shampoo Ruin Hair?

One of the most popular videos on purple shampoo comes from a YouTube creator named Brand Mondo, whose video reacting to people “ruining” their hair with purple shampoo has over 4 million views:

Luseta Shampoo vs. Popular Shampoos

Here's how Luseta Shampoo compares to other popular shampoo brands in terms of potential effectiveness and healthiness, in our opinion:

Harklinikken

Contains an active ingredient derived from coconut oil, which is clinically shown to protect hair proteins from damage.

Lacking formulation from a potential efficacy perspective, but significantly healthier than Luseta Shampoo because it's free of fragrance and synthetic dye.

Winner: Harklinikken

Native Shampoo

Contains fragrance but is free from synthetic dyes.

Also contains two active ingredients we could find research to support (versus one in Luseta), as we documented in our is Native Shampoo good analysis article.

Winner: Native Shampoo

Odele

Contains more active ingredients we consider effective than Luseta Shampoo, and fewer harmful inactive ingredients.

Winner: Odele

Our Clean Hair Care Picks

Acure Vivacious Volume Shampoo is our top shampoo pick.

It contains argan oil which is clinically shown to help protect hair from damage.

Ritual HyaCera is our top hair growth supplement.

This supplement contains wheat oil extract, and a 2024 clinical trial reported that a wheat lipid complex had "a reducing effect on hair shedding and a stimulating effect on hair reappearance and growth."

Both of the products recommended in this section are free of ingredients we consider to be unhealthy.

Luseta Shampoo Pros and Cons

Pros:

• Affordable
• Contains argan oil
• May protect hair from damage
• Brand takes customer complaints seriously

Cons:

• Contains fragrance
• Contains four preservatives 
• Contains synthetic dyes
• Questionable efficacy of core active ingredients
• Doesn’t appear clinically tested

Conclusion

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.

We consider Harklinikken, Native Shampoo and Odele to all offer higher-quality shampoo formulations than Luseta Shampoo.
