We cover the reliability of the Biolage Full Density duo, including who should use it, how they work, what customers are saying, and more. Hopefully, our Biolage Full Density reviews help you determine if this is the right option for you.
Who is it Best for?
If you’re looking for a hair-volumizing shampoo, bring Biolage Full Density into your hair care routine. Formulated with biotin and zinc PCA, Biolage promises to eliminate impurities and deliver lasting, refreshed volume from roots to tips without weighing your hair down.
If you have fine hair, the best Biolage shampoo for you is Volume Bloom which is designed to pump up your hair, especially the roots. It’s worth mentioning that fine doesn’t always mean thin, and vice versa. You can have fine hair with a high density on the scalp, making it look thicker.
According to the manufacturer, Biolage Full Density is suitable for all hair types (from 1 to 4C) and hair textures (fine to coarse), including colored and chemically-treated hair. One thing for sure is that Biolage Full Density won’t help grow your hair but promote fuller-looking hair instead.
Now let’s take a closer look at the products.
The Formula, Scent, and More
Biolage Full Density Shampoo has a soft, thick texture that lathers and distributes easily on your scalp. Although it’s thick, the shampoo washes out easily and has no heaviness to it that can weigh down your hair.
Needless to say, Biolage is widely known for its iconic tall, white packaging which uses 100% recycled plastic, except the caps. It also has a strong minty, but pleasant scent. But it doesn’t last when your hair is dry. While it’s loved by many users, it might bother some with fragrance sensitivity.

Now let’s check the price.
Where to buy Biolage Full Density Shampoo?
We recommend getting Biolage Full Density from Amazon since they often give big discounts. Not to mention its fair shipping cost and wide delivery network make it easy for you to order from anywhere around the globe.
When it comes to pricing, we think Biolage Full Density shampoo is pretty fair at around $23 for 13.5 fl oz and $38 for 33.8 fl oz. Compared to some of the high-end professional shampoos, Biolage Full Density is more affordable. However, some feel the price is higher than drugstore shampoos.
Overall, if you want to get salon-quality results at home, Biolage Full Density Shampoo can be a great option for you. As always, the conditioner is a must to further fortify and nourish your hair. Buy them as a bundle if you are on a budget.

In the next section, we take a closer look at the Biolage Full Density Ingredients to get a better understanding of the reliability and safety.
Biolage Full Density Ingredient Breakdown
Inspired by nature, Biolage is formulated with 100% vegan, no animal-derived ingredients. Biolage Full Density is free of animal testing, parabens, mineral oil, silicone, and artificial color. Given below are the full ingredients of Biolage Full Density Shampoo:
After looking at the list, you may notice lots of unfamiliar, mouthful ingredients. But here, we make it simple for you by breaking down the important ingredients in bold here. This will help you to determine whether or not the shampoo is safe for your hair.
As the name implies, it is a synthetic ingredient made of two components: Zinc and PCA (Pyrrolidone Carboxylic Acid, a naturally-occurring amino acid). Zinc PCA has antibacterial properties that are beneficial to reduce dandruff, excessive sebum, and inflammation. Overall, zinc PCA is best suited for oily, flaky scalps.
While taken orally, biotin helps promote healthy hair, skin, and nails due to its major role in producing keratin. Not only in dietary supplements, but Biotin is also commonly found in hair masks, serums, and shampoos.
There aren’t sufficient studies regarding biotin-containing shampoos that can promote hair growth as it does in dietary supplements.
Since shampoo is only left on your scalp for a short time, the ingredients may not be effective to work at follicle levels. But, it may help deliver a fuller-looking hair appearance, strengthen your hair, and reduce breakage.
Rich in linoleic acid, safflower is believed to help moisturize and nourish the hair, making it supple and easy to comb. Linoleic acid is also believed to help promote hair growth and maintain scalp health.
Since Biolage Full Density Shampoo is a rinse-off product, again, this may not be effective to regrow hair because the ingredient doesn’t have much time to penetrate the follicles. But, you may still gain the benefit of moisturizing the hair.
Sulfates (Sodium Laureth Sulfate and Sodium Lauryl Sulfate)
Getting healthy hair isn’t always glued to your routine, but paying attention to the ingredients is also important to do. If you strictly steer clear of sulfates in any beauty products, then Biolage Full Density Shampoo may not be the right option for you.
Sulfates are great at stripping away impurities, dirt, sebum, and buildup on your hair. However, they are often too good which then strips your hair’s natural oil, leaving hair dry and brittle over time.
Those who have super dry, frizzy, damaged, curly, and coarse hair as well as dry and sensitive scalps may need to avoid sulfates as possible. Colored and chemically-treated hair should steer clear of sulfates as these may strip the hair color and damage the hair.
It serves as an exfoliator that works by dissolving dead cells on your scalp. That’s why salicylic acid is effective to treat dandruff and seborrheic dermatitis.
While most people can gain benefits from salicylic acid, those with sensitive or dry scalps as well as dry hair should proceed with caution to avoid dryness. Always follow with products that feature hydrating ingredients like glycerin.
Biolage Full Density Shampoo features 9 scenting agents in the formulation. These include Fragrance, Limonene, Hexyl Cinnamal, Coumarin, Linalool, Amyl Cinnamal, Geraniol, Isoeugenol, and Alpha-Isomethyl Ionone.
While these ingredients give the product a very pleasant scent, it’s not the best for you, especially if you have sensitive skin or scalp. One study shows that fragrance mix is one of the most common causes of allergic reactions like scalp itching and burning.
Now, let’s take a look at what customers are saying about Biolage Full Density Shampoo.

Many users reported that they’re very happy with Biolage Full Density Shampoo which did wonders on their hair. Here’s a review we found on the brand’s site.
“[My hair] is so thin and damaged and this Full Density Shampoo has added volume and softness with a month’s use. It lathers well and suds all over. It makes my hair so soft as well.”
Another user with postpartum hair loss wrote on Amazon about the great reliability of Biolage Full Density Shampoo.
“I had postpartum hair loss and it was beginning to become very noticeable. It helped my hair not look so thin, gave me volume, and helped fill in the thinner spots. I would recommend blow-drying your hair after using it because that seemed to make a difference.”
Similar to both platforms, Biolage Full Density Shampoo also gained lots of positive reviews. This review comes from a man who also uses Biolage for his beard.
“This shampoo keeps my hair feeling so incredible and healthy. My hair is easier to fix because it isn’t dried out at all. I recommend this to absolutely anyone with a finicky scalp. And it really works well with my beard as well.”
Lastly, another review mentioned that Biolage Full Density Shampoo on Amazon is a legit high-quality product.
“It is a quality product and unlike one reviewer’s photo, they did not compare the same product. If you go on the Biolage website, they refer to Amazon as a source to purchase.”
Let’s take a look at what customers did not like from Biolage Full Density Shampoo.
When it comes to negative reviews, most users felt unsatisfied about the new formula that didn’t meet their expectations. Below are the reviews about someone’s disappointment with the new formula.
“I absolutely loved the Full Density range and have used it for so long. It was the best for my hair and now this new formula has left my hair limp and lifeless.”
On Amazon, we found someone who reported that Biolage Full Density Shampoo stripped her hair, but the conditioner would help to fix it.
“I’m not sure if it’s detoxifying but what I feel is stripping off all oils. You cannot use this shampoo without a conditioner. Once you use the shampoo you can feel the roughness and dryness of your hair. The conditioner helps after but it for sure doesn’t feel fuller.”
Another mediocre review from Influenster noted that the shampoo didn’t bring any improvement in hair volume.
“The smell is amazing as with most Biolage products. I didn’t notice a huge difference in the thickness of my hair, yet it didn’t make it feel oily or heavy either.”
Here is the last review of someone who considers that Biolage Full Density Shampoo is not worth the money.
“No problem with the conditioner, but I don’t find it any better than others I have bought over-the-counter for a fraction of the price.”
After reading the customer reviews, now let’s take a look at the possible side effects of Biolage Full Density Shampoo.
Disadvantages and Possible Side Effects
After taking a deep analysis of Biolage Full Density Shampoo, it seems that the product may not be suitable for everyone or every hair type. Certain ingredients may interrupt your hair and scalp health, especially if you have allergies to related ingredients.
Below are possible side effects and disadvantages of Biolage Full Density Shampoo.
It’s not sulfate-free
Biolage Full Density Shampoo is not sulfate-free. Those who have eczema, contact dermatitis, or a sensitive/ dry scalp may need to stay away from this shampoo.
Although the company claims Biolage is suitable for all hair types. People with extremely dry, fragile, curly, coily, fine, coarse, colored, and chemically treated hair, better steer clear of sulfate shampoo to be on the safe side. Sulfate may strip out too much moisture and hair color.
May cause allergic reactions due to fragrance ingredients
Biolage Full Density Shampoo contains lots of perfuming ingredients. It is advised to do a patch test to avoid allergic reactions if you are sensitive to fragrance.

Contains icky preservatives
The combination of Methylchloroisothiazolinone (MCI) and Methylisothiazolinone (MI) is an effective preservative in Biolage Full Density Shampoo to fight against bacteria, fungi, and yeast. However, this may cause allergic reactions, such as redness, swelling, or itching in people with dermatitis.
If you have a contact dermatitis history, you may need to do a patch test to prevent unwanted allergic reactions.
Contains drying alcohol
Biolage Full Density Shampoo contains Alcohol Denat, short-chain alcohol that evaporates quickly due to its small size. That is why it’s used as an additive to help decrease the time it takes for the hair to dry.
However, this action can lead to hair dryness and frizziness due to it may cause water or oil loss from the hair along with the alcohol. As compensation, it might lead to a rebound-type of effect where your hair and scalp produces excessive oil, leading to greasy and limp hair.
If you notice your hair looks greasy, you can opt for Biolage Scalp Sync Cooling Mint Shampoo No products found. which is designed for oily hair/ scalp. You can also use natural remedies like aloe vera which has been shown to help reduce sebum production.
