Right from volumising shampoos to those for protecting coloured hair or damaged hair, there is a variety of shampoos available. While people may pick one according to their hair needs, they may often think about changing shampoos regularly for healthy hair. It is not just because using the same shampoo can get boring. Many believe that switching shampoos is an ideal thing to do as hair may get immune to the effects of the formula of one shampoo. According to popular belief, if that happens, you may experience hair loss or dandruff or dry hair. Does that mean you need to switch shampoos every few months? We tell you the pros and cons of changing the shampoo often.

What are the advantages of changing your shampoo every three months?

1. Changing your shampoo can help you avoid product buildup

Regularly changing shampoo can prevent product buildup on the scalp and hair, which can lead to cleaner and healthier-looking hair, says dermatologist and cosmetologist Dr Kisalay Saurav. Different shampoos may have different cleansing agents or formulations, allowing for more thorough removal of residues from styling products, oils, and environmental pollutants.

2. Changing your shampoo may address changing hair needs

Hair needs can change over time due to factors like seasonal changes, hormonal fluctuations, or lifestyle habits. By switching shampoos periodically, you can address these changing needs, such as adjusting to climate variations or addressing changes in hair texture or oiliness.

3. Changing the shampoo may prevent resistance

Some people believe that hair can become “immune” to the effects of a particular shampoo over time, leading to decreased effectiveness. Changing shampoo regularly may prevent this potential resistance, ensuring that the hair continues to respond positively to the cleansing and nourishing properties of different formulations, says the expert.

4. It gives you an opportunity to experiment

Periodically changing shampoo allows people to experiment with different formulations and ingredients to find the one that best suits their hair type and concerns. This experimentation can lead to improved hair health, appearance, and satisfaction with hair care products.

5. Switching your shampoo can refresh your routine

Changing shampoo every three months can provide a refreshing change to the hair care routine. It can prevent boredom or dissatisfaction with using the same product continuously.

What are the side effects of switching shampoos regularly?

1. May lead to scalp irritation

Introducing new ingredients to the scalp and hair can sometimes cause irritation or allergic reactions, especially for people with sensitive skin or specific allergies, says Dr Saurav. Regularly changing shampoo increases the likelihood of encountering ingredients that may not agree with the skin, leading to scalp discomfort or inflammation.

2. May disrupt scalp microbiome

The scalp has its own microbiome, a community of microorganisms that play a role in maintaining scalp health. Regularly changing shampoo can disrupt the natural balance of the scalp microbiome, potentially leading to scalp issues such as dandruff, itching, or imbalance in oil production.

3. Results may be inconsistent

Switching shampoos every three months may lead to inconsistency in results, as it can take time for the hair and scalp to adjust to a new formula. This inconsistency can make it challenging to assess the effectiveness of each product and may result in dissatisfaction with the overall hair care routine.

Should you change shampoo regularly?

In general, if you find a shampoo that works well for your hair and scalp without causing any adverse effects, there is typically no need to change it frequently. However, if your current shampoo is causing issues such as scalp irritation or excessive dryness, it may be necessary to switch to a different formula. Also, some people may choose to change shampoo periodically to experiment with different products. Ultimately, the decision to change shampoo regularly should be based on your individual hair care needs and preferences.

What are the signs that indicate you are using the wrong shampoo?

You should change shampoo if you notice the following signs:

1. Scalp irritation

If you experience persistent scalp irritation, itching, redness, or burning sensation after using a shampoo, it may indicate that the formula is too harsh or contains ingredients that irritate your scalp.

2. Excessive dryness

The wrong shampoo can strip the scalp and hair of natural oils, says the expert. This can lead to excessive dryness, flakiness, or a tight, itchy feeling on the scalp.

3. Excessive oiliness

Some shampoos may be too heavy or contain ingredients that overly moisturise the scalp. This can result in an oily or greasy appearance shortly after washing.

4. Dull or limp hair

If your hair looks dull, lifeless, or lacks volume after shampooing, it could be a sign that the shampoo is not providing adequate cleansing or nourishment.

5. Residue buildup

Some shampoos may leave behind a residue on the hair or scalp, causing buildup over time. It can weigh down your hair and make it appear greasy or dirty, even after washing your hair.

6. Allergic reactions

If you develop allergic reactions such as hives, rash, or swelling after using a shampoo, it may contain ingredients that you are sensitive to or allergic to.

How to choose shampoo according to your hair type?

Here are some tips to choose the right shampoo:

• Dy or damaged hair: Look for moisturising shampoos that contain ingredients like oils, shea butter, or glycerin to help hydrate and nourish the hair.
• Oily hair: Opt for clarifying or oil-control shampoos that are formulated to remove excess oil and buildup from the scalp without stripping away too much natural moisture.
• Fine or thin hair: Choose volumising shampoos that add body and texture to the hair without weighing it down.
• Colour-treated hair: Use colour-safe shampoos that are sulfate-free and specifically designed to protect and prolong the vibrancy of dyed or highlighted hair.
• Sensitive scalp: Look for gentle, fragrance-free shampoos that are formulated for sensitive skin and free of potentially irritating ingredients such as sulfates, parabens, and artificial fragrances.

Also, make sure not to wash your hair too often, especially if you have dry hair.
