Who is it for?
Inspired by water-resistant camellia, Biolage SmoothProof is specially tailored for frizzy hair that needs humidity control and anti-frizz agents. Dryness is the primary factor that can exacerbate frizz.
There are several essential causes of why your hair become dry and frizzy, for instance:
- Humidity: If you live in a humid zone (Florida, Texas, or Southern California), are traveling somewhere warm, or passing hot, summer days, then Biolage SmoothProof can be your go-to shampoo.
- Diameter of the hair fibers: Basically, frizzy hair is the effect of misaligned hair fibers. And, those with thick hair fibers usually find it hard to realign the hair.
- Curly hair is prone to frizz. The curlier the hair, the harder it is to realign the hair.
- Hair damage: Over-heat styling, sun exposure, or coloring can lead to split ends and breakage. This eventually gives frizz-looking hair because the hair fibers aren’t running in the same direction.
SmoothProof Shampoo tames your frizzy hair with camellia that works in a two-way approach.
- First, provide rich hydration to rejuvenate your hair’s natural moisture.
- Second, give protection against humid weather that can swell the hair cuticles, making moisture move in and out of the fibers.
Now let’s take a closer look at the shampoo.
Biolage SmoothProof Shampoo: The Texture, Scent, and Packaging
The shampoo has an incredible light texture and disperses easily onto your wet hair. It’s not the type of heavy shampoo that leaves residue and a stiff feeling to your hair. It lathers nicely to cleanse all grime and rinses out with ease.
It has a pleasant, soft floral scent, and isn’t too strong or perfumey. Overall, most users have no headaches from using it. If you’re not a fan of fragrance, it doesn’t linger for a long time. So, it might only bother you during lathering.
The SmoothProof Shampoo comes in eco-friendly white packaging in two sizes. The 400-ml bottle has a slender design with a yellow flip-top lid. It’s also easy to tip the bottle upside down to get the last drop. The 1-liter bottle doesn’t come with a pump, so it might be too big in your hand while pouring the shampoo.
Let’s check the value of Biolage SmoothProof Shampoo.

At just $23 (for 13.5 fl oz / 400 ml), this smoothing treatment is more affordable than some of the high-end professional shampoos out there. With its high-quality formula and generous size, the Biolage SmoothProof Shampoo is good value for money.

Next, we take a closer look at the ingredients of Biolage SmoothProof Shampoo.
Biolage SmoothProof Shampoo Ingredients Breakdown
This paraben-free formula is infused with lots of hair-conditioning ingredients that are largely targeted at frizzy hair. The new-and-improved formula of Biolage SmoothProof Shampoo is certified vegan and cruelty-free. Given below is the full list of the product ingredients:
In this section, we take a look at the standout ingredients of Biolage SmoothProof Shampoo and how they work individually.
Glycerin
It is a real hero for curly, thick, dehydrated, coarse, and frizzy hair that needs extra hydration, though it is good for all hair types. Glycerin is an effective humectant, which attracts moisture from the environment to your hair and keeps it there. It is also beneficial to help reduce frizz, split ends, and breakage.
Additionally, glycerin may help treat dandruff and dry scalp for an optimal scalp environment. Click here to learn more about glycerin.
Amodimethicone
A water-soluble silicone modified from dimethicone. Amodimethicone is usually used in hair care products for curly, wavy, and textured hair to help enhance curl patterns and doesn’t weigh down the hair.
Amodimethicone helps improve hair shine, reduce frizziness, and lock in moisture by creating a protective layer on top of the hair cuticles. One study suggests that as this may build up your hair, taking a few sessions with a clarifying shampoo can remove all the residue.
Polyquaternium-10
It is readily soluble in water that acts as an anti-static agent, which is great for frizzy, curly, and thick hair. Polyquaternium-10 helps to reduce frizz, improve hair’s manageability, and define curls. It is also beneficial to strengthen hair that has been damaged physically or chemically.
Salicylic Acid
It is an anti-dandruff agent which makes it very helpful to treat flaky, oily, and itchy scalps. Generally, salicylic acid is a chemical exfoliator that works by breaking down dead cells on your scalp and removing excessive sebum.
Propylene Glycol
It is a water-soluble synthetic compound made of a combination of propylene oxide (derived from refining petroleum) and water. Propylene glycol can draw moisture from the air to keep your hair stay hydrated (humectant), which is very useful for dry, curly, and frizzy hair.
It also acts as a preservative that prevents the growth of mold, fungi, and bacteria.
Camellia Kissi Seed Oil
It is a truly promising ingredient that has more than 80% oleic acid and antioxidants. Camellia may help fight against free radicals that can damage your hair. Camellia kissi oil also helps to moisturize and soften dry hair due to its fatty acid content which is shown to promote skin and hair smoothness.
Now we know that Biolage SmoothProof Shampoo is rich in powerful replenishing ingredients that are beneficial to promote well-hydrated and smooth hair. It is also infused with anti-dandruff agents which makes it also suitable for those with flaky scalps for deep cleansing.

Reviews from Different Hair Types, Textures, and Concerns
“I’ve used this on my daughter for over 5 years. She is very active and has shoulder-length hair, which creates a lot of tangles and split ends. This shampoo truly helps.” – 5 stars
“I have fine, combo/oily hair and it doesn’t weigh my hair down at all.” – 5 stars
“I have curly hair (3b to 3c) and I only truly wash my hair once a week. Curly hair = frizz so I was happy to try this shampoo” – 4 stars
“My hair is coarse and wavy. Since I started using this it cuts my straightening time.” – 5 stars
“I have very thick, wavy, shoulder-length hair but at even the slightest hint of humidity, my hair frizzes. I live in Southern California so frizzing happens frequently.” – 5 stars
“I have very fine hair, annoyingly. It’s more flyaways than frizz really, but this calmed it quite a bit.” – 4 stars
Biolage SmoothProof Shampoo seems to work great on almost all hair types and textures. Not only does it helps people with thick hair that usually deals with frizziness and tangles. The product also works best on fine hair to calm flyaways without adding weight to it.
Product Reliability
“I am 72 with graying hair that wants to frizz or stick up or out. This product makes my hair feel soft and smooth but not flat, thin, w/o body, and my natural waves remain.” – 5 stars
“It’s good and it does its job, it leaves my hair soft. But I feel like it’s for dry scalp, mine is normal-oily.” – 4 stars
“This Biolage shampoo doesn’t give me any obvious improvement. It’s not a bad shampoo, but it’s nothing special and doesn’t make my hair look less frizzy or particularly smooth or good. The sulfate-free shampoos give me better results and seem less drying.” – 3 stars
“My hair is so smooth and soft since using this shampoo. With the humidity at its worst, I have noticed that my hair doesn’t get frizzy as it used to.” – 5 stars
“I was having trouble with my hair all winter long. It was so staticky that I couldn’t even wear my hair down without pieces flying everywhere. I finally bought this shampoo and I am so happy. My hair has never felt this soft or had no static since summer.” – 5 stars
“I’ve been using the Biolage for color-treated hair for years and love it. I found this version to leave my hair feeling greasy rather quickly.” – 3 stars
Overall, Biolage SmoothProof Shampoo works as advertised, helping deliver smooth and frizz-free hair, even in the worst humidity. However, it seems not everyone notices better improvement. Some find that the shampoo makes their hair dry out due to the sulfate or makes their hair limp.
