Okay, a question asked by our clients often: “Is shampoo bad for your hair?” The answer is no, but the types of shampoo you use can frequently affect your scalp and hair health.
Yet, when it comes to hair care, shampooing is essential to keeping hair clean. So, when is a shampoo bad for your hair, and how must you choose the right one?
The short answer is that shampoos contain surfactants, which help remove impurities, oil, and dirt. The surfactants surround the hair particles, suspending them until they are rinsed.
There are three types available: gentle, medium, and firm. Variables that range between each other are other factors to consider when deciding which type you need.
How Can Your Shampoo Damage Your Hair?

Depending on the type of shampoo you choose, selecting the wrong one can have adverse effects on your hair and scalp:
- The wrong shampoo can strip your natural oils, as some contain harsh chemicals like sulfates. It removes dirt and the essential oils your scalp needs to nourish and protect your hair.
- Once the natural oils are removed, your hair becomes weak and susceptible to environmental concerns, leading to split ends and frizz.
- Shampoos containing silicones can accumulate on your scalp and hair, leading to a buildup that weighs your hair down and may cause various scalp conditions, including dandruff.
- Some shampoos can cause an allergic reaction from the chemicals, leading to a sensitive scalp that is red or itchy.

What Types of Shampoos Are Bad For Your Hair?
When looking at types of shampoos harmful to your hair, it does not mean you should not use them, but instead consider how often you use them:
- When used frequently, Shampoos containing harsh sulfates strip away natural oils, leaving hair dry. These shampoos are best for oily hair but use them sparingly.
- While dry shampoo is excellent for occasional use to help absorb oil, overusing it can lead to scalp buildup. It should never be used as a replacement for your regular shampoo.
- If you have color-treated hair and use blue or purple shampoos, be aware that you may expose yourself to harsh chemicals if you don’t use a sulfate-free one. Also, limit your use to once a week.
- When you visit us for a scalp treatment, we sometimes use a clarifying shampoo to remove residue. However, when overused, it can strip away moisture, so it is advisable to use it at least once a month, followed by a deep conditioner.
When is Shampoo Bad For Your Hair?

While shampoo is not bad for your hair, there are times you must limit your shampooing. Frequent shampooing can remove the natural oils your scalp needs to nourish your hair, especially if you have dry or damaged hair.
In this case, it helps to reduce your shampoo use by using it only a couple of times a week or choosing hydrating formulas. Washing your oily hair too much can stimulate oil production.
We recommend washing it every other day and using a gentle shampoo to help balance the oils on your scalp. On the other hand, underwashing your hair, especially when styling, leads to scalp issues. We recommend a balanced routine to keep your scalp clean and healthy.
If you have curly hair, it can be dry and frizzy, and over-shampooing can exacerbate the issue. Limiting your washing helps, so choose a sulfate-free moisturizing shampoo. Lastly, washing your hair two to three times a week is usually sufficient for most hair types; adjust the frequency according to your needs.
What Shampoo Should You Use?

To choose the right shampoo, you must understand your scalp condition and hair type. While most shampoos have a list to indicate what performance you will reach, they can include:
- Dry hair,
- Oily hair,
- Color-treated hair
- Normal hair
- Sensitive skin
- Volume and more
These formulations are tailored to your hair type and feature moderate surfactants to maintain cleanliness and balance. The characteristics can vary depending on the formulation, with supporting ingredients tailored to meet your specific needs.
Alternatives to Use

If you want to reduce the frequency of shampooing in your hair care routine, you can find gentle alternatives to maintain your hair’s health. These include:
- Dry shampoo is used between washes to absorb excess oil and refresh your hair. Use natural formulas containing plant-based ingredients, but be mindful not to overuse them.
- Co-washing, also known as conditioner washing, is an alternative method for maintaining clean and healthy hair. It involves using conditioner instead of your shampoo. It is particularly beneficial for those with dry or curly hair.
- You can use apple cider vinegar to rinse your hair for a natural conditioner that balances your scalp’s pH levels and leaves your hair with a shine. Use two tablespoons in a cup of water. Rinse your hair with it after your regular wash to help remove buildup, and add some essential oil, such as lavender or rosemary, to mask the smell.
- Other options include herbal and clay rinses, which naturally cleanse the hair and remove dirt and oil.
- If you have a sensitive scalp, we recommend using a sulfate-free shampoo. The same applies to chemically treated hair. It is gentle on the scalp and hair.
