Hair washing is not a universal practice that applies to everyone in the same way. The frequency at which you should wash your hair depends on several factors.

The American Academy of Dermatology Association (AAD) provides some general guidelines:

  • Oily Hair: If you have oily hair, you may need to wash it daily to control excess oil and maintain a fresh appearance.
  • Dry Hair: Wash less frequently if you have dry hair. Because overwashing can strip away natural oils and lead to dry and damaged hair. Washing every few days or when necessary is recommended.
  • Chemically Treated Hair: In the case of chemically treated hair, such as dyed or permed hair, washing less frequently can help you preserve the hair’s integrity and prevent color fading or damage.
  • Textured or Coily Hair: For textured or coily hair, you should consider washing hair once every 1–2 weeks. Frequent washing can strip natural oils, leading to dryness and potential damage.

As you age, your scalp tends to produce less oil. Meaning you may not need to wash your hair as often. Pay attention to your hair’s appearance and then adjust your washing routine.

Should You Wash Your Hair Daily?

Keep in mind, daily hair washing is not necessary for everyone.

A PubMed article suggests that the frequency of hair washing depends on various factors, including:

  • Hair length
  • Personal preference
  • Culture
  • Social influences

Daily washing is suitable for people with oily hair. Others may only need to wash their hair every few days. It’s important to avoid excessive washing to maintain the natural balance of oils in your hair.

What Factors Affect How Often You Should Wash Your Hair

Environmental Factors

Environmental factors impact how often you should wash your hair, such as:

  • Pollution
  • Sweat
  • Product or oil buildup

Do you live in a polluted area or have an active lifestyle that leads to excessive sweating. You may need to wash your hair more frequently to keep it clean and free from environmental impurities.

Additionally, if you are used to styling products like gels, mousses, or sprays. Washing your hair more often can help prevent product buildup. Otherwise, it will make your hair appear dull.

Lifestyle Considerations

Your lifestyle also plays a role in determining your hair washing frequency. For example, if you exercise regularly and sweat, you may need frequent hair washing.

If you swim in chlorinated pools or saltwater, washing your hair removes damaging substances.

Or if you lead a sedentary lifestyle and your hair doesn’t get exposed to excessive dirt or sweat. You may be able to stretch the time between washes.

What Is the Best Way To Wash Hair

The best way to wash hair without causing damage includes:

  • Use a non-harsh shampoo whenever possible to minimize potential damage to your hair.
  • Use a small amount of shampoo and focus on massaging it into your roots. Don’t apply shampoo directly to the hair shafts, as this can lead to dryness and damage. Avoid vigorous scrubbing to prevent hair damage and scalp irritation.
  • Allow the shampoo to run down the hair shafts for proper cleaning.
  • Do a gentle towel-dry your hair or let it air-dry.
  • Avoid excessive heat styling to maintain your hair health.

How Do You Know Your Hair Need Washing

An oily or dirty appearance, product buildup, or a dull look may indicate you need to wash your hair. Other signs also tell your hair needs washing. These are:

  • Oiliness: If your hair appears greasy and feels oily to the touch, you need to wash your hair. Excess sebum production can make your hair look and dirty.
  • Dirty Appearance: When your hair starts to look visibly dirty, with dust, or product buildup. It’s time to wash your hair. The accumulation of debris can make your hair appear dull.
  • Unpleasant Odor: If your hair emits an unpleasant odor, it’s time for a wash. Sweat, environmental pollutants, and product residue lead to an unpleasant smell.
  • Itchy Scalp: An itchy scalp can be a sign of dirt, sweat, or product buildup. If you constantly scratch your scalp, it’s an indication that your hair needs cleansing.
  • Changes in Texture: You might feel your hair heavy, sticky, or rough to the touch. It may be a result of excess oil, sweat, or styling products. Washing can help restore its natural texture and cleanliness.

It’s important to note that everyone’s hair is different. The frequency of washing can vary depending on your hair type, scalp condition, and preferences. Pay attention to these signs and adjust your hair washing routine to maintain a healthy and clean mane.

Choosing the right shampoo will help you maintain healthy hair. Different shampoos cater to specific hair types and conditions.

Here are some guidelines for selecting the right shampoo.

  • Normal Hair Shampoo: This type of shampoo is suitable for hair if you have not undergone chemical treatments and your scalp produces moderate oil. Normal hair shampoos provide minimal conditioning and effective cleaning.
  • Oily Hair Shampoo: Shampoos formulated for oily hair do not contain conditioners. Therefore suitable for individuals with excess oil production.
  • Dry Hair Shampoo: Have you undergone chemical treatments or harsh styling procedures. Choose a shampoo specifically designed for dry hair. These shampoos offer good conditioning properties and mild cleansing.
  • Deep Cleaning Shampoo: If you use styling products like gel, mousse, or hairspray, consider using a deep cleaning shampoo. These shampoos contain specific ingredients, such as lauryl sulfate, for the effective removal of product buildup from the hair shaft. It’s advisable to use this type of shampoo once a week.
  • Professional Shampoo: Professional shampoos are typically used by hair stylists before cutting or styling the hair. They are not meant for daily use.
  • Medicated Shampoo: If you have scalp conditions like psoriasis, seborrheic dermatitis, or bacterial or fungal infections, medicated shampoos can provide relief. These shampoos contain active ingredients to target specific conditions.
  • Everyday Shampoo: These shampoos are designed for daily cleaning and contain mild cleansers. They usually don’t contain conditioners. So if you opt for an everyday shampoo, also use a separate conditioner.
  • Baby Shampoo: Baby shampoos contain mild detergents. They are suitable if you have sensitive scalps or prefer gentler hair care products.

What Are The Best Alternatives To Shampoo?

Several alternatives to traditional shampoo are worth using. They can help prevent scalp dryness and hair damage. Some common alternatives include:

Cleansing Conditioner: Cleansing conditioners combine cleaning properties with the benefits of a conditioner. They can serve as a replacement for shampoo, providing gentle cleaning without stripping away too much natural oil.

Dry Shampoo: Dry shampoo is a popular choice if you have oily or fine hair. Or if you want to prolong the time between washes. It’s important to note that dry shampoo does not remove dirt or debris from the hair. It can also leave a powdery residue that may cause irritation or buildup.

Apple Cider Vinegar Rinse: Diluted apple cider vinegar can act as a natural clarifying agent. It removes buildup and balances the scalp’s pH. Mix one part vinegar with three parts water and apply to hair. Wash hair after 2 to 3 minutes.

Remember, the effectiveness of these alternatives may vary depending on your hair type and needs. It’s always a good idea to experiment and find what works best for you.

What Overwashing Do to Your Hair?

Overwashing can have several negative effects on hair health and appearance. It’s important to find a balance and wash your hair according to your specific needs.

Here’s what overwashing can do to your hair.

Strips Natural Oils: Washing your hair more often can strip away the natural oils that keep your hair moisturized and protected. This can lead to dryness, frizz, and a dull appearance.

Dry Scalp: Excessive washing can disrupt the balance of your scalp’s natural oils, leading to dryness and irritation. It may cause itchiness, flakiness, and discomfort.

Breakage and Damage: Overwashing weakens the hair shaft and makes it more prone to breakage. It can also strip away the protective cuticle layer of the scalp. Thus making your hair vulnerable to damage from environmental factors and styling tools.

Increased Oil Production: Overwashing can also stimulate the scalp to produce more oil as a compensatory mechanism. This can result in an oily scalp and greasy-looking hair.

Fading Hair Color: If you have colored or treated hair, frequent washing can cause the color to fade. The chemicals in shampoos can strip away the color molecules, leading to dull and less vibrant hair.

To maintain your hair health, it’s important to find a balance and avoid overwashing. Pay attention to your hair’s needs, consider your hair type, and adjust your washing frequency.


In summary, determining how often to wash your hair depends on various factors, such as hair type, oiliness, and the presence of sweat, dirt, or styling products. People with oily hair or who use hair care products daily may need to wash their hair more frequently. While those with dry hair can wash it less often.

Individuals with textured or coily hair should wash their hair once every 1–2 weeks. Choosing the right shampoo for your hair type and using proper washing techniques can help you maintain healthy and beautiful hair.
