The shampoo secret beauty companies don’t want you to know

Conny tells The Beauty Brains she has a very sensitive scalp with fine hair and suffers from hair loss and dandruff. Dermatologists have advised her to use a clear gel shampoo that has to be clarifying or deep cleansing. So, she’s tried Suave Daily Clarifying Shampoo, Suave for Men Deep Cleansing shampoo, Neutrogena Anti-residue shampoo, and Prell Classic original formula. She’s not happy with those choices and is asking us to set her straight.

The Right Brain responds:

While we hate to disagree with dermatologists, we don’t understand why they recommended a deep cleansing shampoo when you have dandruff. Deep cleansing type shampoos will remove the surface flakes, but only a dandruff shampoo can control the cause of flaking and itching. So we’d recommend finding a good dandruff shampoo instead of chasing deep cleaning, clarifying and anti-residue products. This may seem confusing to you because the beauty companies tell you there are SO many different kinds of shampoo. But in reality, every shampoo on the market falls into a few basic categories.

There Are Only 4 Different Shampoo Types In the World

All shampoo can be categorized by their basic functional category. So then why are there eleventy million products on the market, you ask? Because the companies that sell shampoo need to find new ways to talk about their products to keep them sounding new and exciting. There’s nothing wrong with them being creative about their names and claims as long as the companies are honestly depicting what their products can do. But you can be a smarter consumer if you can see beyond the marketing hype and understand the functionality of these 4 basic shampoo types.

1) Deep Cleansing Shampoos

(Also known as Volumizing, Clarifying, Balancing, Oil Control, and Thickening.)

These shampoos are designed to get gunk off your hair and scalp. They typically contain slightly higher levels of detergents so they foam and clean better. They include the examples above as well as salon products like Paul Mitchell Shampoo 2. and Frederic Fekkai’s Full Volume.

2) Conditioning Shampoos

(Aka Moisturizing, 2 in 1, Smoothing, Anti-frizz, Strengthening, Color Care, Straightening, and Hydrating)

This kind of formula is all about leaving a moisturizing agent, like a silicone or Polyquaternium 10, on the hair to smooth it and help straighten hair. It’s very good for dry hair, especially if you color treat or heat style but it can weigh down fine hair. Good examples of this type includes most of the Pantene formulas and some products from the L’Oreal Vive collection and Dove ProCare.

3) Baby Shampoos

(Aka Kids shampoo, and Tear-free)

Johnson’s Baby Shampoo is the classic example but this category also includes Touch Of An Angel and The Little Bath. These are milder, lower foaming surfactant formulas that are designed not to sting or burn your eyes. They’re better for babies but they don’t clean hair as well.

4) Anti-Dandruff Shampoos

(Aka Anti-itch, Flake Control, and Dry Scalp)

Head and Shoulders is the leading dandruff product; other examples include Nizoral and Redken Dandruff Control . These are medicated shampoos that contain a drug ingredient that controls itching and flaking. In the United States these are considered to be Over-the-Counter (OTC) Drugs.

The Brains Bottom Line:

Hopefully, this helps you better understand the marketing hype around shampoo names. We’re not saying that all shampoos are the same, or even that all shampoos in a given category type are the same. There are real performance differences, so it’s important that you shop around and find a product that performs the way you like at a price that you can afford. But just don’t get too hung up on the names the companies use to describe the products. That’s the marketing part of the industry, not the science part.
