Can Shampoo Cause Hair Loss? A Few Myths & Points To Remember

When you notice excessive hair fall while shampooing, you immediately think of changing the shampoo. But does shampoo cause hair loss? It seems counterproductive to everything they stand for and claim. Here are a few things you may want to consider.

Not all shampoos may cause hair loss or damage your hair. It depends on the product’s formulation, which depletes the scalp of natural oils and damages your hair. Hair loss can also be caused by how often you shampoo and how much shampoo you use. Read on to learn what ingredients to avoid in shampoos to prevent hair loss.

Ingredients You Should Avoid

If you’re wondering why hair falling out in the shower after shampooing? One reason could be shampoo. Do check the ingredients in your shampoo because several ingredients in shampoos can contribute to hair loss. Some of them can be irritants and cause scalp inflammation, making your hair thin and brittle. High alcohol percentage in the shampoos can dehydrate your hair. Ingredients, such as mineral oil and petroleum, which are used as lubricants, might weigh the hair down. Hence, look for shampoos that are devoid of such ingredients.

Here’s what you need to avoid:

• Sulfates

Ammonium lauryl sulfate (ALS) and sodium lauryl sulfate (SLS) are the two most common sulfates used in shampoos.

They are strong detergents that have good cleansing and foaming properties that create a rich lather. But the downside is that they can make your hair dull, frizzy, rough, and prone to tangling (1). These sulfates are potential irritants, even at low concentrations, and cause hair damage. If you notice chunks of your while you are shampooing, know that your shampoo has a huge concentration of sulfates.

• Sodium Chloride

Sodium chloride, also known as table salt, is used as a thickener in shampoos.

It might dry out your hair and scalp and cause eye irritation and itchy scalp. High concentrations of sodium chloride can also cause hair loss (2).

• Formaldehyde

Formaldehyde is an antibioticⁱ  A type of antimicrobial substance that inhibits or slows down the growth of bacteria in the human body. that helps keep your shampoo safe and shelf-stable.

But high concentrations of formaldehyde can cause contact allergy and rashes (3). It is also considered a carcinogenⁱ  Any substance, agent, or ingredient with the potential of causing cancer or increasing its risk. (4). Formaldehyde and other preservatives penetrate the hair and interfere with hair growth and cause damage, leading to hair loss.

Did You Know?

Sweden and Japan have banned the use of formaldehyde in cosmetics and toiletries as it is a possible carcinogen.

• Propylene Glycol

Propylene glycol acts as a humectantⁱ  A substance commonly found in shampoos and lotions that is used to preserve moisture in the skin. and helps nutrients penetrate your scalp.

However, high levels of propylene glycol may cause scalp irritation or allergic reactions (5). It may also worsen hair thinning. If you cannot find shampoos without this ingredient, opt for products with a low concentration of propylene glycol.

• Alcohol

Stearyl, cetearyl, and cetyl alcohols are found in many shampoos. These alcohols are very drying and might strip the natural oils of your hair. Thus, use shampoos with less concentration of alcohol.

• Fragrances

If you have sensitive skin or hair, avoid artificial fragrances and colors in your shampoos. They can cause scalp irritation. Switch to fragrance-free shampoos.

The following section has busted some myths related to shampoos and hair. Scroll down to know more.

Common Myths About Shampoo And Your Hair

Myth 1: If You Use Same Shampoo For Long Time, Your Hair Stops Responding.

You have probably heard that changing your shampoo every once in a while is necessary because your hair gets used to it and does not respond to the formula any longer. However, the truth is far from this.

If your shampoo is not as effective as it used to be, it might be due to changes in your lifestyle, food habits, or medications. It might also be due to a change in the formula or the wrong formula for your hair type. Too many surfactantsⁱ  Chemical compounds that reduce the surface tension between two liquids, allowing one to mix well with the other. in the shampoo can leave your hair dry, or too many ingredients can coat the hair and weigh it down. Hence, the solution is not to switch up shampoos but to choose one suitable for your hair type and issues.

Myth 2: Your Hair Will Clean Itself Without Using Any Shampoo.

If you do not wash your hair, it will gather dust, dirt, and be coated in the sebum and oils releases from the sebaceous glandsⁱ  Present in the skin and hair that release an oil called sebum, which keeps the skin and hair lubricated. . Shampooing once a week is a must. Heard of the no-poo method? This involves washing your hair with a gentler alternative to traditional shampoos – like vinegar, baking soda, or just water. The no-poo method helps prevent scalp irritation and dryness caused by harmful ingredients in your shampoo. It also helps reduce the overproduction of greasy oils on your scalp. By avoiding shampoos, you are limiting your hair’s exposure to irritants.

Myth 3: Frequent Shampooing Damages Your Hair.

A shampoo not meant for your hair type or with harmful ingredients can damage your hair. Frequent shampooing strips the natural oils of your scalp and causes dryness. Thus, use a shampoo as per your hair type, and follow up with a leave-in conditioner. Remember, overusing any hair care products might hamper your hair health.

Myth 4: All Natural Shampoos Are Safe.

Not all natural shampoos are completely safe for everyone, as some may cause irritation or allergic reactions, especially for sensitive scalps. It’s important to read the ingredient list carefully and test the product on a small patch of skin before using it properly. Additionally, the term ‘natural’ is not strictly regulated, so some products may still contain synthetic additives. Always check for transparency in labeling and choose a shampoo that suits your hair and scalp needs.

Quick Tip

While shampooing, ensure you do not pile up long hair on top of the head. It may cause hair breakage and tangling.

How Often Should You Shampoo Your Hair?

It depends on your hair type and scalp health. If you have dry hair, shampoo not more than twice a week. On the other hand, oily hair types may require daily washing. If you have a normal hair type, shampoo your hair whenever you feel like you need it.

To reap maximum benefits from shampooing, remember these points.

A survey conducted on 5793 Americans found that 29% shampooed daily, 31% shampooed 3 to 4 times a week, 26% shampooed 1 to 2 times a week, and 11% shampooed less than once a week. Out of the 31% that shampooed 3 to 4 times a week, 27% were male and 35% were female.

There are many reasons for hair loss, and an unsuitable shampoo or persistent hair wash could be some of them. However, to determine the exact reason, it is crucial to know what type of hair loss you are facing. Is shampoo a reason or some other underlying health issue, such as hormonal imbalance, poor diet, etc.? This will help you find the right solution for the stated concern.

Points To Remember

• Massage your scalp frequently to improve blood circulation and achieve healthy and shiny hair. Aaliyah, a hair blogger, frequently massages her scalp to grow strong and healthy hair. She recommends,”You can give your scalp a good massage when washing your hair like I do, or another great way is to massage an oil (like Jamaican Black Castor Oil) into your scalp whilst upside down before you wash (i).”
• Avoid 2-in-1 shampoo and conditioner products as they cause product buildup.
• Use a leave-in conditioner for extra smoothening and moisturizing your hair.
• Rinse your hair with lukewarm water as cold water discourages blood flow to your scalp.

Clearly, using the right shampoos plays a major role in controlling hair loss. But how can you choose the right shampoo? Keep reading to know more.

How To Choose the Right Shampoo

• Pick a shampoo made specifically for your hair type, such as kicky, curly, straight, and wavy, or hair issue, such as oiliness, dryness, frizz, and more.
• Focus on scalp needs, like hydrating formulas for dryness or clarifying shampoos for oily scalps.
• Avoid harmful ingredients like sulfates, parabens, phthalates, and alcohol, which can strip natural oils, cause dryness, or irritate the scalp.
• If you have a sensitive scalp, look for gentle, fragrance-free shampoos to minimize irritation.
• Match your shampoo to your hair goals, such as adding volume, controlling frizz, or repairing damage.
• Check the ingredient list and ensure transparency. A good product clearly mentions its ingredients without vague terms like ‘fragrance’ or ‘proprietary blend’.
• Look for nourishing ingredients like aloe vera, argan oil, keratin, or biotin, depending on your hair’s needs.
• Test a small size or sample first to see how it works for your hair before committing to a full-sized bottle.
• Read reviews to learn about others’ experiences, especially from people with hair similar to yours.
